Manga: Chapter 8

Kazuma Saji (左治 一馬, Saji Kazuma), also known as Zaji (ザジ, Zaji), was one of the first people Akira Sengoku met on the island. Kazuma was originally part of another group consisting of his childhood friend Masakazu Yoshimoto. Kazuma was usually alone during the school which caused him to treasure the people around him much more.


Kazuma appears as a dark-skinned muscular man. He wears a long singlet that is rugged and torn at the bottom. The singlet is usually accompanied by text saying something like "Reflection"-- this often changes throughout the series. Kazuma wears the usual male school uniform slacks and also the white sneakers. Kazuma has black hair that is not only long, but spiky. He usually is seen with a white bandana around his head. He is relatively tall and also has been seen swapping his shirt around as seen by the different text.


Kazuma originally appears as a carefree, perverted delinquent. At first, he was someone who complained about not wanting to die during the epidemic case and someone who was often messing around and enjoying himself. As he has a crush on Kanako Oomori, he is constantly seen trying to impress or partner up with her throughout the series. He also comes across as a tough and strong individual, despite his common perverted jokes and antics. During the series, he was commonly not recognized by the others which caused him to blush and show embarrassment. He has also shown to get angry or fustrated easily and also bring out his anger in violent means as seen by both his actions towards Masakazu and Shirou Mariya.

Despite this, he is also someone who is kind and determined to protect anyone he considers a friend. He isn't afraid to put himself in danger for other people and later is even ready to put his own life in danger despite anything to save Kanako during the kidnapping case. He was always like this too, when wanting to save Masakazu. He also regretted not being able to save him during his time on the Cursed Mountain, he was having illusions of Masakazu attacking him. To him, he considers all his friends apart of his own family because of his complicated family history. Despite his perverted nature, Kazuma would never force a girl into anything they were uncomfitable with, showing greater moral fiber than most males in the series.


He was both childhood friends with Masakazu and Maya. He once attended Miyauchi's dojo, but quitted pretty soon and was seemingly ditched by Masakazu when Kazuma's grades dropped. He didn't have a good reputation at school and people thought him as a delinquent. The first girlfriend he dated was also a friend of his sisters. In Akira's memories, it seemed he had no friends in school and his only friends were children.

In his childhood, he lived with a complicated family who mainly didn't care for him. In the outside, they did look like a loving and happy family, but however it was noticeable that none of his family paid any attention to Kazuma, which he knew. His real mother had actually ran off with another man and his father quickly remarried whilst his new mother didn't care a bit for Kazuma and only paid attention to his sister. His father was also someone who didn't care for children and acted as if Kazuma was invisible that made it seem that Kazuma was a person who actually lived alone even in his own house.


Raft arc

Kazuma first appears when Akira's Group came out from the jungle and found him alone on the beach. He wasn't alone. Masakazu, Masanori Tanaka and Mina Mukouda were there with him, but they went out gathering materials. Akira introduced his group to him and asked what was he doing. Kazuma simply replied he was building a Raft and wanted their help. He's planning to leave the island with the Raft. Akira's Group was stunned by his plan. They thought it was a bad idea. Kazuma pointed out somewhere in the ocean. There was another island nearby. Shirou calculated the distance is 5 km. On behalf of his group Akira agreed to help Kazuma out. Before shaking hand with Akira, Kazuma flipped the skirts of Kanako and Rion Akagami up. Masakazu, Masanori and Mina returned from gathering materials for the Raft. Shirou pulled out his Laptop and showed them a picture of Andrewsarchus. Kazuma and his friends immediately recognised the animal from the second night on the island. He described the animal in details to them. Masakazu added that the Andrewsarchus won't come near the beach, because of its nature. When they were running short of materials again Kazuma suggested he will go with Rion and Kanako, but Akira put a stop to that. In the end Akira, Rion and Kazuma headed out. Kazuma smelled something odd and they hid inside the trees. He saw a Meiolania getting attacked by an Andrewsarchus. They hurried back to the beach to inform the Andrewsarchus' attack. Upon return Kazuma hit Masakazu for his mistake and left. Akira left also to bring Kazuma back. Kazuma told Akira about his history with Masakazu. After that Akira and Kazuma walked back to the group.

Kazuma heard screams from the jungle. Masakazu, Masanori and Mina had been away for a while. Akira and Kazuma will check it out. They tracked the screams down and saw Andrewsarchus tossing Masakazu around. They jumped into action. While Kazuma held the animal's mouth, Akira swoop down and saved Masakazu. The Andrewsarchus eventually broke free of Kazuma's hands. It chased the fivesome back to the beach. An Ambulocetus jumped out from the water and grabbed Rion. The rest of the group were stuck on the beach with the Andrewsarchus. Kazuma and Akira defended themselves with wooden sticks while the rest was pushing the Raft into the ocean. It broke through the defense and ate Masanori up. The Andrewsarchus was in pain. Akira ordered the group to leave with the Raft. They climbed onboard leaving Akira behind. Mina immediately bit Kanako on her hand and Masakazu hit Kazuma on his head. They pushed Kanako and Kazuma off the Raft. The helpless Shirou was the last one to get off. Kanako and Kazuma were back on the beach. She saw Shirou drowning in the water. Kazuma didn't want to go back to the ocean because of the Ambulocetus. Kanako didn't want anyone else to die. So stripped off her clothes and dived into the ocean. Kazuma followed after her. Both of them dragged Shirou back to the beach only after they saw the Raft destroyed by the Basilosaurus. Back on the beach Shirou, Kanako and Kazuma were walking along the shore when they saw Akira and Rion being alive. The next morning they left to find a suitable place for Rion to heal. Before leaving Kazuma found Masakazu's shoes on the beach and hung it up on a stick for his friend.

Epidemic arc

Akira and Kazuma stood guard outside the cave for three days. Kazuma confessed to him, he liked Kanako. His first time was his friend´s girlfriend. Akira might even have a shot at Rion in this world. Akira, Shirou and Kazuma accompanied Kanako to the lake. An Arsinoitherium raise from the water and headed toward them. Kazuma left his Spear behind and ran away. The Arsinoitherium just ran passed them and started to eat the Berries. Shirou informed Kazuma that Akira has the best chance of surviving here.

Akira’s Group were eating the fruits from the nearby trees. Shirou informed Kazuma that the cave is the ideal refuge to settle. Shirou, Kazuma and Kanako heard a scream near the cave. Motoko Kurusu was surrounded by a group of Nemegtbaatar Gobiensis. The rest of Kouichi's Group came out from the bush. Kazuma watched as Kouichi Yarai refused to shake hand with Akira. Kouichi and his boys just walked past them and ransacked the cave. Kazuma didn´t say much when Itou asked what he was looking at. Before the boys can do any more damage, Kouichi sent his boys out for food.

Akira’s Group heard some noise in the jungle, so Akira went in to investigate. The next morning the rest of Akira’s Group heard what happened in the jungle last night. Kazuma seemed happy that the Kouichi´s boys were beaten down by Megaladapis Edwardsi. He had now a chance and asked Akira to help him finish them up. Akira declined and Kanako thought Kouichi is very cool. Kazuma became very angry for Kanako’s comment. Motoko wanted everyone to leave this island together. Before she said anything else, they found her lying on the ground. Everyone was stunned by her fever. They carried her back to the cave. Kazuma felt sorry for the teacher, because they didn´t have doctor around here. Akira’s Group was forced to leave the cave because Kouichi said so. Akira thinks Kouichi did that on purpose. Only his group was infected. Not before long Shirou was infected. Akira carried Shirou back to the cave. Kazuma and the rest soon followed after them. He thought the infected people were just exaggerating with their fever. Kazuma first saw Ono to die first. After Kouichi and Akira buried Ono, Kazuma caught the disease. His eyes had turned red also. He didn´t want to die like Ono.

Kouichi, Rion and Akira returned with the cure the next morning. He heard Kouichi and Motoko left together. One by one Akira’s Group started to get better.

Rion tied Kazuma up a tree after suggesting searching the area slowly. The next day they were caught by Shinzou Karino's men. Shinzou threated to kill them if Akira wouldn't surrender himself. He noticed the blood stains on the men's clothes. Shirou knews something is wrong here. They heard Shinzou explained the event toward Towa's death.

Brain Loss arc

Akira’s Group arrived at the river. They decided to rest and take a separate bath. His mind started to wander about Kanako taken a bath. Akira asked him if he would watch Miina for a while. Miina made him to swim while Miina sit on his back. After crossing over the riverbank he was exhausted from swimming and carrying Miina on his back. Kanako and Rion returned from bath with an unconscious Yuki Sakuma. Akira recognised her as a classmate. Yuki woke up and immediately requested Akira to save Kouhei Arita. Yuki informed Akira’s Group about a demonic murderer killing her group. Akira’s Group and Yuki headed upstream the river. Akira asked more information about the demonic murderer from Yuki. Yuki told the event that led them to a Limestone Cavern and ended up finding them. Akira told the story how he met Kouhei for the first time. Akira’s Group followed upstream until they hit a dead end. They took a detour around and suddenly they fell through a sinkhole.

After landing underground Kazuma saw a rockface on a wall. As they explored the area they find Gerrothoraxes, Kannemeyerias and Lystrosauruses. They saw something else. They found Tamura's dead body. They found three passages ahead of them. He suggested tunnel two with no particular reason. Shirou backed up his choice and Akira accepted it. They found themselves a dead end. Akira climbed through cliffedges to the other side and tied up a rope for him and others to crossover. Akira’s Group found themselves back at the place where they first landed there. They headed now to another tunnel. Rion and Yuki left the group to pee. After a while Akira’s Group heard a scream. Akira, Shirou, Miina, Kazuma and Kanako were shouting for Rion and Yuki. Suddenly Kanako went missing from behind. Shirou started to believe the murderers had kidnapped Kanako. He didn't believe it at first, but Akira did. Together they sent out to find their missing friends.

Akira dashed and prevented Kouhei from stabbing Kanako. The others came to Kanako's aid. Kazuma, Miina and Shirou were stunned when Kanako called Akira to stop attacking Kouhei. Miina and Kazuma watched as Shirou looked at Kanako's wound. Miina will suture the wound while Shirou and Kazuma had other tasks to do. Kazuma blocked Kouhei from fleeing the scene. For his trouble Kouhei hit him hard. He wouldn't let Kouhei passed the exit. Kazuma woke Akira up from his initial shock. Akira stood up and started hitting Kouhei with all his strength. Kouhei revealed his action to Akira’s Group. He saw a Cyclotosaurus walked by. Kazuma ignored it until it bit a piece of his shoe off. A swarm of Cyclotosaurus surrounded Akira’s Group and Kouhei. He didn't understand why they would eat them. The boys defended themselves while Miina sutures Kanako's wound. After it was done, Akira and Kouhei will carry Kanako to safetly. Kazuma and Miina protested against Kouhei. But they didn't have any other choices. They alone evaded the Cyclotosaurus with ease until they started to fly across the room. He thought Akira and Kouhei would have more difficulty evading the animals. But he was wrong, they were able to crossover with no problem. They escaped safetly into the tunnel only to find the remaining members of Arita's Group. Akira tried to warn him, but Kazuma got hit by a stone from Ueno. Kouhei stopped his group from attacking Akira’s Group. He led his group away. Akira heard a yell and rushed to Kouhei's aid. Miina and Shirou followed after him. Kazuma stayed behind to watch over Kanako.

He was relieved to see Akira came back with the missing Rion and Yuki. Kazuma reported Kanako just fainted not too long ago. They heard a rumbling sound headed their way. The water level started to rise up. They started to head back where they came from. They found out that Motoko and Yuki are above ground. They lowered a rope for them to climb up. Akira noticed the water level dropped. Shirou warned them a flash flood was about to hit them. Akira, Kazuma, Shirou, Rion and Kouhei ran back to the tunnel. They encounter a fork road ahead of them. Kouhei advised them to head down and he and the others followed after him. They found themselves at a dead end. Kouhei revealed that the river connected to the outside.

Inside the School Camp they encountered students from various classes. Takashi requested his group to help them building a country. Together with the teacher Kawai and Fujimoto, Takashi explained to Akira’s Group the event after the incident until they reached here. Akira’s Group watched as Takashi pulled up a new flag symbolising their new country. Kazuma started to help out with his new job as Technician. At night he slept in the same tent as Akira.

The next morning he heard Miina went missing. Akira’s Group couldn't find Miina anywhere. On the fence he saw Miina lying on the ground. He went back and reported to Akira. Akira, Rion, Shirou, Yuki and Kazuma saw a group of Canis Dirus were approaching Miina's position. Akira and Kazuma climbed down the fence and headed toward Miina. They found Miina tied down on his hand and his face was bloody. Kazuma warned Akira that the Canis Diruses are about to attack them. Luckly the Alpha Wolf Ernest called off the attack and the pack returned to their leader. Akira saw Ernest with its scar on his nose. They carried Miina back to their tent. Shirou examined Miina and told the group that Miina might have some aftereffects.

Rion, Shirou, Kazuma and Yuki woke up the next morning and saw Akira destroying the School. Everyone was confused why he does it. Akira’s Group listened when the teachers and Takashi tried to reason with Akira. The teachers accidently revealed Miina being a boy. Akira asked Kazuma if he had told anyone. He wouldn't do that. Nobody outside Akira’s Group knew Miina is a boy. The teachers revealed their true intention about the School country. Feeling they had lost the group Kawai and Fujimoto left the School. After the crisis had settled down, Akira’s Group packed up their belonings. Akira told his group about his dream a couple days ago. He was afraid Takashi will kick them out.

They came across a rocky cliff area. Akira saw someone and called his group to investigate. Behind the big rock they encountered a bandage man called Tooru Rinzai. Rei Ooguro and Kotomi Kawana were pleased to meet them. They requested the Exploration Party to help them. Their belongings got stolen by a wild dog. His face got pulled by Rei when he asks the contents of the bags. Kazuma started to sweat from walking under the sun. Kotomi cleaned his face off and asked him to endure it a bit longer. Akira yelled at him to remind him of Kanako.

At dawn they tracked down their belonings. When they were close, they discovered they enter a trap made by the dire wolves. He asked Akira what to do. When nothing happened, he saw an Arctodus Simus attacking the wolves. The Exploration Party and their friends were surrounded by two animals. Rion suggested they hide inside a crevice. When inside Takashi, Kazuma, Rion yelled at Akira and Rei, because they were chased by the bear.

After a while Akira, Kazuma and Takashi took a peek on the outside. The animals were on a standoff. Takashi suggested they should leave while it is raining. They headed out and watched out for other crevices and the animals. He heard Rion's scream from behind and saw a trio of Artodus Simus. While Akira ran after Rion, they encountered another Arodus Simus themselves. Kazuma saved Akira from the bear's attack while he was thinking about Rion. They couldn't outrun the bears. The wolves came and attacked the bears. The wolves were no match against the bears. Akira believed the pack are protecting Ernest's pregnant wolf. They hurried back to Rion's fallen crevice. Once inside they decided they will not give up on the fight. Takashi suggested to split into two group to escape, but Akira prefered they went out together or die. When climbing outside he saw an Artodus Simus pulled Akira out of the crevice. Rion wanna saved Akira, but Kazuma pulled her back. They got out when the wolves started to scratch the bears' noses. They heard a scream. Kotomi was hurt. They climbed back to the crevice to rest. Rei explained to the group of Kotomi's past. The group named the Alpha wolf Ernest after hearing Takashi's story.

The next morning they heard Ernest's howl. They got up and found Akira and Kotomi missing. Ernest lured them to Akira's position. Along the way Kazuma found Rei's panties dropped from Rei's bag. They found Akira hurt on the ground and Kotomi dead. They buried Kotomi before heading back to camp. Along the way he hoped Akira won't die on them. They brought Akira inside the tent. Before he can explain to everyone, Miina kicked him between the legs. He blamed him for Akira's condition. Luckly Akira saved him from Miina. Everyone was relieved to hear his voice. People started to leave the tent. Shinji Gotou asked him about Rei and Tooru. He explained to Shinji and Tadashi Katou about Tooru's scar. When Tooru took of his bandage, they were stunned by his cool scar. He felt confidence they are safe inside the School Camp.

Argentavis arc

Kazuma watched as Kanako walks around the Camp. Everyone wanna talked to her. He stood in Akira's tent looking over her. He made a complain to Akira about seeing her first. Akira just told him that maybe Kanako isn't into him anymore. They made a small fight until Maya arrived in his tent. She ordered him to leave on a patrol. He left without a fight.

Akira’s Group heard a scream from outside the fence. Sanae Kashiwagi pointed above the cause of her scream. An Argentavis landed on top of Ryouichi Suzuki. They were stunned by the new huge animal. The Argentavis flew toward them and they ducked to avoid the hit. Luckly the bird flew away. Akira’s Group discussed the new threat. Shirou explained the basic of Argentavis to the group. He wondered why it attacked them and don't they only eat corpses. Shirou pointed out that they view them like rats they eat sometimes. Shirou suggested they make pairs. One will look into the sky while the other does something. Takashi helped Kazuma pairing up with Kanako. He got a bit jealous when other people wanna stay close to Kanako as well. Someone cried out that the Argentavis has returned. The Argentavis swoop down and caused chaos inside the Camp. He tried to protect Kanako, but an Argentavis pushed her away from him. The Argentavis advanced toward Kanako. Kazuma intervened and protected her of the hit from the bird. He grabbed Kanako's hand and they flee the scene.

He heard Akira's whistle outside the fence and called the Argentavis to feast on him. Everyone was stunned by his sacrifice. From his act the group started to fight back and drove the Argentavis off the Camp. At night Kanako made a sling for Kazuma. The next morning they found the deaths of Matsushita, Ken Tanaka, Murata and Takao Sugimasa. The group lived in fear of the unknown disease. Shirou found the cause and called everyone to head toward the river. He told everyone to wash their bodies thoroughly and not to touch the ticks. Shirou called them poisonous ticks. Akira figured it out how the ticks enter their camp. Someone yelled out. It appeared the Argentavis has returned again. They made a dive attack above the river. He saw an Argentavis is about to attack Maya. He warned her and Maya ducked to avoid the attack. She schold him for being here. Across the field they both saw Miina stood near an Argentavis. Luckly Akira came and saved him from the bird. Another bird came and it tried to grab Kazuma. He blocked it with his wooden stick. He watched as Akira caused harm on the Argentavis' chest. Maya grabbed Kazuma's wooden stick and pierced it throught the bird's chest. The others flee after seeing a death of their own. They had won a battle against an extinct animal. Akira believed that they need to leave before night falls. Akira’s Group packed up their stuff and met Akira on the outside. They watched as the camp sat into fire. Shirou suggested they head toward the mountain.

Akira’s Group was tracking through the jungle. Kazuma listened as Shirou explained why they have to travel to the top of the mountain. He recalled the event at the ocean. They need to see if they could find a coastline somewhere on top. And also on top they could see other survivors. At night they made small campfires.

Cursed Mountain arc

Akira’s Group were on their second day heading to the mountain. Kazuma and Maya scouted the area ahead of them and found no dangerous animals nearby. They returned and informed Akira. Akira told Shinji, Kazuma and Takashi about his dream last night. He dreamt about girls were approaching him. In his mind he dreamt a nude image of Kanako.

They reached the base of the mountain. Everyone was ready for the climb. Kanako noticed something is rolling down the mountain. It landed next to a bush. Akira, Maya, Kazuma and Takashi investigated the object and warned the group not to look at the dead body. Akira’s Group started to freak out of the situation. On their way to the top they discussed what happened to the person and why. The climbing got quite a steep. The group changed its line according to Tooru's advice. They encountered some wind as they further climbed up. A slide trail was found and a student id on the ground. It belonged to Noriaki Matsuki. They suspected he wasn't alone on the mountain. The mist is getting thicker. They found Nagatsuka from Class 1. He recalled Noriaki came back to life and chased after them. They encountered a cliff. Akira climbed up and lowered the ropes for everyone to climb up. After walking for a whole day they decided to rest behind huge rocks.

As the sun raise on top of the mountain, Kazuma couldn't move his body. He suffered a hallucination like almost everyone else. Maya tried to calm Kazuma down, but failed. Akira came back and told the group about his hallucination. Shirou preferred they solved the hallucination before it kills them. As the mist cleared out from the view, they saw the top is near them. Akira ordered everyone to climb up. The group followed Akira's order. The image of the island astounished them. The land went beyond the horizon. They discovered a Pile of Rocks with a shirt stuck inside. It had a message for them. The group headed down the mountain a bit to recover. During the descent to the base of the mountain everyone seemed to recover very well.

Mami the Clairvoyant arc

Akira’s Group were surrounded by a pack of Pristichampus. They were on their backs against the wall. Kazuma tried to hit the Pristichampus with his stick. But it got shatter by its bite. Someone on top of the cliff yelled at them to run to the river. They jumped into the river and the Pristichampuses stood at the riverside. Akira and Tooru came back from their talk with Mami's Group. Kazuma swore to have seen Mami Kagura from somewhere. Kanako asked if Mami is her type. He quickly denied it. Suddenly he recognied her as Mami the Clairvoyant. The rest of the group seemed to hear of her. Kazuma wanted Mami's signature on his shirt. Mami's Group and Akira came back to his camp. Kyouko Nakayama told the group about Mami's premonition. Akira’s Group discussed about the letter W. Shinji overheard the whole conversation and walked angerily away. He listened as Tadashi told Shinji's past with premonition.

Takashi came running into camp. He followed the group as they found Shinji and Tadashi dead near the cliff. Rion pointed Akira out that the dead bodies look like a W. Akira’s Group freaked out of the premonition. Tadahiko Uchimura came to the burial. He recalled the event after the incident. Most of his group died in the bottomless swamp. Tadahiko recommended them to believe in Mami's premonition. Masayuki Ikeda and Shouji Mukai came and relayed another premonition to them. Akira’s Group started to freak out. Kanako asked Kazuma to stay away from her. Shirou recruited Kazuma and Maya to follow him and Kanako. After the meeting with Kyouko, they followed Shirou and Kanako into the forest. Mitsuhiro Muramatsu and Kyouko came out of the bushes. Mitsuhiro took a swing at Shirou and Kanako. Kazuma pushed them away as Maya blocked the attack. Shirou finally revealed his master plan. Kyouko got away after punching Kazuma on the face. He felt down on the ground with a single hit. They brought Mitsuhiro back to camp. They accused him as the killer of Shinji and Tadashi. Kazuma brought Mami and the rest of her group to camp. Mami had another death premonition, but Akira’s Group didn't believe her. Akira ordered everyone to find Kyouko first if they wanna know if Mami wasn't lying about her premonition. They came across the Pristichampus. Akira’s Group defended themselves with sticks against the Pristichampus. They came to Mami's rescue. Mami revealed she has another death premonition. Akira reorganised his group to protect Mami as they headed to the river. Shirou noticed the Pristichampus' tactic and suggested their legs are their weakness. Maya made a spinning leg sweep and the animal lost its balance. Kazuma made an attempt and failed. Akira and Mami were the last one to jump into the river. The whole group was saved again.

They walked along the river for four or five hours. They decided to rest on a sandbank middle in the river. Akira and Shirou came back from their walk. Kazuma told them they will host the first "Queen of the night contest". Each boy will get one vote. Everyone was astonised by the results. He freaked out as someone else voted for Kanako too. Kazuma suspected Tooru as the second voter. Rei came along and found the contest out. At night Kazuma and Kanako decided to walk somewhere. Kazuma held her when she wanna returned to camp. Kanako recalled the event when she saw him for the first time. She thought Kazuma being irreplaceable person in the group.

Zaji comforting Kanako after being rejected

She preferred reliable guy when Kazuma asked her what kinda guy she likes. In return Kazuma described the girl he likes. All the qualities she quickly thought about Yuki the girl Kazuma likes. She thought Kazuma wanted her out here as being a cupid to them. Kazuma accidently said Yuki likes Akira. Being stubborn she didn't listen the last comment. At last Kazuma confessed his love to her. She bowed to him as she couldn't return his love. Feeling blue, he knew he's just a kid compare to her. He helped Kanako up and saw her face with tears. Even he's rejected by her, he will protect her even it costs his life.

Gigantopithecus arc

Akira’s Group had stayed at the sandbank for a day and they are ready to leave. Kazuma's eyes were still red from last night with Kanako. They found Pile of Rocks left behind by Makoto. It led them to a jungle.with huge trees. They decided to make camp before heading into the jungle.

Kazuma and the others heard Rion's cry near the camp. Rion told them what happens to Kanako and her. Shirou found the footprints of the animal. They were afraid of the size of the animal. Akira decided to go after her. Kazuma hoped Kanako will be saved soon. Along the footprints they also found Kanako's jacket. They noticed a little blood spot on it. Akira’s Group was now heading deep into the jungle. Their supplies of Torch Pine were burning out. They need to fan out to search for more. Kazuma asked Yuki if she could help him lighting the torches. She reassured him that Kanako is fine. In return Kazuma reassured Yuki about her feeling toward Akira. When the last torch went out, the unknown animal started its attack. Out of the darkness an Eusmilus came out and faced the unknown animal. Akira’s Group hid behind the trees and watched the confrontation between the two animals. Eusmilus attacked the unknown animal and got killed by it. Moonlight shined on the silhouette and Shirou recognised it as a Gigantopithecus. After killing the Eusmilus, the Gigantopithecus left the scene. Akira’s Group were now afraid of Kanako's attacker. Even Shirou gave up on Kanako. Kazuma beat him up for that. Akira stopped Kazuma from beating Shirou to death. After the beating down Akira and Kazuma will rescue Kanako on their own. Shuu volunteered to join the rescue. Mami had a premonition when Kazuma touches her shoulder. She had seen what will happen to him. They followed the footprints' trail. Kazuma revealed to Akira that he confesses to Kanako last night. He got rejected by her. They came across three Gigantopithecuses. Kazuma suggested he will create a diversion for Akira and Shuu to find Kanako. He will apologise to Shirou when he get back. After all, the group is his family. Kazuma created a diversion and the three Gigantopithecuses chased after him. A Gigantopithecus was about to grab Kazuma, but it got stuck between two trees. His thought was thinking about Kanako that he lost track of the three Gigantopithecuses. He turned his head and saw only one Gigantopithecus behind him. He wondered where the other two Gigantopithecuses went. A Gigantopithecus emerged in front of him and another Gigantopithecus blocked the other corner. Kazuma found himself trapped between the three Gigantopithecuses and a cliff. A fourth Gigantopithecus came out of the bushes. It gave the others the signal to attack Kazuma.



Shirou came down the cliff to help him against the Gigantopithecuses. They were now trapped at all corners. Shirou whispered something to Kazuma's ear. They headed toward a Gigantopithecus. The Gigantopithecus attacked them and missed. Shirou and Kazuma split themselves apart and come around behind Gigantopithecus' back. Kazuma thanked Shirou for coming to his aid. The four Gigantopithecuses still chased after them.

being chased

Kazuma found it weird why they were chasing human in the first place if they didn't encounter them before. Shirou concluded they have encountered human before in the jungle. Shirou was hurt by the Gigantopithecus' attack. Kazuma helped him up. Shirou was thinking in his mind when he didn't notice the Gigantopithecus is about to hit him. Kazuma pushed him away to take the hit. It drove Kazuma against the tree and landed hard on the ground. Maya pulled him in the bushes when the Gigantopithecus smashes the spot where Kazuma used to be. Shirou dove into the bushes and found Kazuma and Maya. Maya came down to deliver a message to Kazuma. The Gigantopithecuses were on top of them. They left the scene. Maya noticed that Kazuma was lagging behind. In response Kazuma complimented Maya for having good asses. He knew they will get out of this since they have Shirou with them. They came across an area of dead Meganeura Monyis. Shirou figured out the solution of their problem. Before he could do that, he noticed some changes on Kazuma. But Kazuma was fine according to his words. They started a fire on a nearby bushs. But the fire spreaded out so fast that they couldn't escape from the smoke.

Luckly Akira came and carried them away from the fire. The rest of the group returned and carried them to the edge of the jungle and found an old footprints trail. Blood was leaking behind Kazuma's back. Kanako thanked Kazuma for saving her life. He offered to take the rear as the group move forward. More blood was dripping on the ground. On his back there is a big hole leaking blood. He was pierced when the Gigantopithecus hit him to the tree and the branches were sticking out. He lost his balance as he lost so much blood. Kazuma saw a way out without making Kanako to cry about. He voluntary fell off the cliff. Akira’s Group had climbed down the cliff, but they couldn't find Kazuma's body anywhere.

At the valley the girls were talking about Kazuma's death. Kanako felt sad about her loss. Maya was the only one who can cheer Kanako up by using Kazuma's quotes. In the end Kanako hugged Rion for thanking everyone for their encouragment words.
