Fei is a playful Japanese soccer player, who is always there for his friends, though he doesn't know how to call out for help when he needs it. He has no family, other than his sibling, you, who he cherishes and wishes to protect with his life. He's a little bit of a gamer as well, and he's the type to learn of the game's lore, no matter how deep or not it is. He just likes learning about things that interest him, especially history and mythology.
