Main characters

 * Akira Sengoku (仙石 アキラ)
 * 3rd year, class 4, is the main character of the series, a Japanese schoolboy. He seems to be a bystander who reacts to events rather than choosing his own destiny. He is regarded by his fellow students as a lazy good-for-nothing. He is not much of a reliable guy but in times of peril he springs courageously into action that helps the group survival, and eventually making him the leader of the group. He also seems to have a crush on Rion but can't express his feelings to her since they are childhood friends.


 * Rion Akagami (赤神 りおん)
 * 3rd year, class 1, is a pretty, athletic girl who is considered the school's number one idol and the ace of the Gymnastics Club. She is Akira's childhood friend and may have a crush on him.


 * Kanako Oomori is a plucky young flight attendant who survives the crash. She acts as the group's medic. Even though, at first, she is seen as not very smart (she failed her flight attendant test 16 times before passing as the storyline begins) she is actually quite intelligent, knowing all the chemicals that could be used for first aid and more serious wounds. Being with Akira gives her the courage to survive and protect the others to the best of her ability.


 * Shirou Mariya, 3rd year, class 4,is one of Akira's classmates, a rude yet timid boy with a high IQ who is considered the school's prodigy. He is extremely knowledgeable about prehistoric animals and has a scientific database in the laptop computer he carries with him.


 * Arita Kouhei, 3rd year, class 2. Handsome and popular, he is a tall natural athlete and the star of the school volleyball team. He is Akira's best friend. He is the one who stabbed the pilot with a knife. He won't allow anyone to find out his secret.


 * Motoko Kurusu is a young female schoolteacher from Akira's school . She is very kind and has a great relationship with her students. She admires Kouichi as a natural leader and follows him throughout the island.


 * Hades is a mysterious, mentally disturbed student who claims he is the "Lord of Hades." He conceals his identity with a souvenir mask bought from Guam. In his mind, this world they have fallen into is survival of the fittest and he plans to kill anyone and everyone on the island. He also instigates Arita to become a murderer after he tricks him into killing an innocent girl to protect his secret. He seems to have a vendetta against Sengoku. It is unknown as to which student he is yet.


 * Kazuma Zaji, 3rd year, class 3, is a classmate from Akira's school. He's a delinquent with perverted thoughts about women who never takes things seriously and loves to joke. He tends to let his emotions get the better of him, like when punching Yoshimoto when he was wrong about the monsters and panics about it. He used to be childhood friends with Yoshimoto until his grades fell in junior high and they became distant. He tried to become friends with him again, but later discovered they were just using him to escape and Yoshimoto kicks him overboard. He later decides to join up with Akira's group and becomes good friends with them.


 * Isurugi Miina, a 10 year old little transvestite boy that supposedly 'bosses' over a camp consisting of some adult passengers that were not a part of Sengoku's class.
