She has had feelings for Akira since childhood but does not want to admit it. She would take care of him, drag him to school, help him with homework, and look out for him. After the crash, she went into hiding from the chaos that surrounded the survivors. Akira later found her and has followed him since. She is a quick witted actor, bighearted and very flexible, allowing her to attack from angles that no one thought possible. Whenever a smaller group is formed for recon, she is always a member. She is frequently jealous when some other girl shows affection for Akira.

 * A teenage prodigy who carries a laptop that contains facts about prehistoric fauna and flora. He was ranked first in his class for nine years in a row. Thanks to his encyclopedias, intelligence and wit, he is the group's strategist when he helps Sengoku in his plans and acts as his second in command. He carries around a portable charger for his laptop. Shirou tries to be logical, often suppressing his emotions to make rational choices. He lost his mother at a young age. Shirou's stoicism is an attempt to hide his pain by wearing an emotionless mask. As a result, he had few friends before the crash, but sometimes, he wished to have many friends, like Sengoku. After a fight with Zaji, he realizes that he should stop wearing the mask and start thinking of his friends as well. Later, he is announced as Sengoku's second in command.

He was at first bullied by everyone until Sengoku stood up for him, and he became popular by the end of the year. the star of the volleyball team, and very popular with girls, he tried to keep up the mood of the survivors, but after learning they could not go home, he snapped and killed the pilot in his rage. Kouhei originally led a large group of survivors, but was haunted by his sin and wished for Sengoku to help him, despite thinking that he was dead. He slowly sinks into murderous paranoia after suffering a serious head injury and starts killing the survivors and make the remaining 4 insane murderers like him. After getting into a conflict with Sengoku, he regrets his actions, and attempts to atone by helping Sengoku's group escape a flash flood inside a cave and is presumed to have died when he stayed behind.

 * Kanako Oomori (大森 夏奈子)
 * An air stewardess who joins Akira's group. She is very knowledgeable in first aid, although she is also quite clumsy. She has low self-confidence, but only has pride in her large bust.

She grew to be rather close to Zaji and took her some time to overcome his death.


 * Kouichi Yarai (矢頼 光一)

In truth, Miina is using the Yakuza not to rule the camp but to protect "herself" as Miina had witnessed the men in "her" camp rape and accidentally killed a woman named Towa, an air stewardess and colleague of Kanako.

He rose to power when the rest of the group fell ill and he claimed to have the only cure, leaving to die the former leader and his daughter, laughing the entire time. He wanted to kill Akira for scratching his face and manipulated Yarai into trying kill Akira in exchange for saving Motoko's life.

 * Basilosaurus
 * A huge, serpent-like whale. Mina Mukouda and Masakazu Yoshimoto hijacked a raft for themselves and headed towards the 'other island', leaving Akira's group to die, only to find out that it was just a rock. The Basilosaurus then emerged from the water, destroyed the raft and devoured both.


 * Arsinoitherium
 * A rhinoceros-like creature related to elephants and dugongs. While at first Akira believed it was docile, it is revealed that this individual was sick, poisoned with the same berries that were killing the survivors.

Akira and Rion are saved from being trampled by Yarai.


 * Megaladapis
 * A huge lemur. A group of them appears when Ono, Itou and Mikoshiba (members of Yarai's first group) were bullying a baby, and Yarai fought them off until they recovered the youngster. One of them was still attacking Akira, which caused Yarai to start laughing at him, surprising everyone, including the lemur.


 * Nemegtbaatar

 * Hyaenodon
 * The rivals of the entelodonts. A large pack appeared attracted by the blood and carnage caused by the entelodonts and the murder of Miina's bodyguards, killing the other survivors and even fighting the entelondons for food. One of them finds Shinzou Karino, the man who had led the gang rape and murder of Towa, and ate him.


 * Dire Wolf
 * A pack of them is led by a scarred individual that Akira nicknames Ernest. Akira and his exploration party end up in their territory and find themselves in the middle of a fight between the wolves and the short-faced bears, with the wolves refusing to back down since Ernest's mate was pregnant. Akira's group and the pack of wolves reach to a some sort of understanding about not harming each other and they work together to scare off the Arctodus. Ernest later saves Akira by leading the others where he had fallen from a cliff.


 * Arctodus
 * The short-faced bear. One of them scarred Tooru and Akira's exploration party found themselves in the middle of a territorial fight between a trio of bears and the pack of dire wolves. The wolves and the survivors scare them away by attacking their noses, the most sensitive part of their bodies.


 * Argentavis
 * The biggest flying bird in history. A flock appears to attack the survivor's base and one nearly kills Suzuki. While the survivors manage to scare them away temporarily, it turned out they carried poisonous ticks that killed some of the students.

 * Chalicotherium
 * A relative of the horse with a gorilla-like body and long claws. Despite being herbivores, they're really aggressive. A trio of them attacks Yarai and Saki when they intrude in their feeding grounds, and one injures Kurusu. Yarai scares them away by breaking the claw of one of them.


 * Pristichampsus
 * A crocodile with long legs, adapted to hunt on land, hence why it isn't a good swimmer. A large group is let into the plateau were Akira's group was staying by Kyouko Nakayama, Mami's manager, who wanted to kill them, but the crocodiles devoured her and most of her group instead, with the only exemption being Mami herself. The group manages to escape from them by going to the river.


 * Gigantopithecus
 * The biggest ape in history. A family kidnaps Oomori and Kirino to be used as practice prey for their youngster. One of them easily killed an Eusmilus with its strength and intelligence. When Mariya decided to help Zaji escape from them, they realized that the apes had already encountered other survivors, and one of them fatally injures Zaji. Mariya, Zaji and Miyauchi scare them away by setting on fire a Nerium oleander, a plant whose poisonous smoke makes them flee.


 * Titanis
 * The terror bird. This birds became capable of imitating human voices like parrots, and all they say is "help me" after hearing it many times from its victims. A flock comes to attack the survivors at their base at The Tower alongside the Propleopus and the Smilodon, and one of them tries to eat Suzuki, only to spit him out. Tokiwa and Sengoku bring them down by taking advantage of their inability to make sharp turns and some are finished off by the Smilodons.


 * Propleopus
 * Carnivorous kangaroos. A group comes to attack the survivors alongside the Titanis and the Smilodon.

 * Rodhocetus
 * A primitive whale between Ambulocetus and Basilosaurus. A group attacks Yarai's group when they're investigating the Lighthouse, and one of them manages to get inside and tries to attack Saki, but she's saved in time by Kouichi.


 * Chimera
 * A monstrous failed experiment that was hibernating underneath The Tower and awakened when the trap holes surrounding it where unearthed. It looks like a gigantic, three-headed Smilodon with an armored back, human-like arms, and an incredibly long tongue. It has a 360° field of vision thanks to its six eyes, but a terrible depth perception and color distinction. It swallows Miina(Fake) whole, but Mariya deduces its organs still don't work properly because of the hibernation, so the group manages to save "her" by stabbing it in the stomach until it collapses, and its then finished off by Akira and Kouichi.


 * Chimera II
 * A second failed experiment that awakened alongside the first one, and was dragged back to the trap hole by Kouhei in order to let Akira and his group kill the first Chimera. It looks like a demon, with ram-like horns, an anteater-like tail and goat legs, capable of leaping great lengths. Kouhei blinds it and later breaks one of its horns, until he's able to kill it.


 * Paraceratherium
 * The biggest land mammal that has ever lived, a gigantic giraffe-like rhinoceros.
