The characters bios were taken off a website. When Im not lazy I will right the description just not for sometime now though... Sorry D:

Tsukasa:Tsukasa is kind of a loner and doesn't like attention - just wishes everyone would leave him alone. In the real world, no one knows for sure who Tsukasa really is.

Mimiru:In "The World", Mimiru is a swordsman. In the real world, she's a teen, and her real life personality transfers to her character in "The World". She likes meeting new people, but has a tendency to get mad quickly if she feels they are rude to her. She tends to spend most of her time in the game around Bear.

Bear:In "The World", Bear is a warrior and the more fatherly figure of the game. He seeks to protect, and to unravel the mystery of Tsukasa. In the real world, Bear is a middle aged man. He has taken the initiative to investigate the circumstances in the real world to find the real Tsukasa in hopes of helping him.

Subaru:In The World, Subaru appears to be a guardian/semi-goddess, who commands a lot of respect from the other players. When she asks something, it usually gets done. She is the leader of the Scarlet Knights, but sometimes disagrees with their philosophy. She believes that they are there to fulfill a role, but that they have certain boundaries that they cannot cross without interfering on players’ rights. Subaru is very serious, very concerned with responsibility, and becomes deeply concerned about Tsukasa and his condition. He becomes a close friend of hers because she perceives them as being so similar. In the real world, we don't know much about her, although it appears she is an older teen and possibly a loner.

Crim:In "The World", Kurim is a very powerful spearsman. It appears that he used to have Ginkan’s position as Subaru’s protector, but had to stop playing the game for a while and so gave that position up. To Kurim, this is just a game and he is constantly reminding people that they should be playing to have fun. There's enough responsibility in the real world. Here, you should do what you enjoy. For the most part, though, he keeps his online and offline personalities separate, only ready to reveal his offline nature to Subaru. In the real world, Kurim is a business man.

BT:In The World, BT doesn't take responsibility as seriously as many of the characters, and because of that, tends to switch loyalties whenever it suits her. She and Mimiru don't get along, but she seems to respect Bear and Kurim, although she appears to be jealous of Kurim’s relationship with Subaru. Because of her nature, she is the person Sora harasses the most. In the real world, BT appears to be a girl in her upper 20s who plays the game to escape reality.

Sora:In The World, Sora is an anarchist who loves intimidating people with his maxed stats. If he meets someone who won't act according to his wishes, he'll kill them on the spot. He acts solely for himself, at the expense of anyone else involved. Out of "The World" Sora is a forth grader.

Sto:Sto is Tsukasa's guardian. He protects him from enemies throughout the show when he is told to. The bad thing about Sto is that he won't stop until the character is dead, and in the real world the person playing as the character is knocked unconcious and loses a small amount of memory, but nobody knows how and why that happens.

Cat:Cat was a servant of the voice in the server where Tsukasa found Aura. Later on though the Cat betrays the voice and helps out Tsukasa instead.
