Yuuki Asaba is one of the main characters of the Kimi to Boku anime and manga.
Yuuki is the younger of the Asaba twins and attends Homare High School with the rest of the boys. He is generally summarized as the more laid back of the twins, as well as being the more athletic and agile.
In the AWA fics, Yuuki is a student at the AWA Academy and is a part of Class 23. Yuuki is also part of the AWA Rookie 20 and his ranked #3.
In the TWA fics, Yuuki is one of the major characters. Yuuki is part of the Honor Fighting Force and is a member of The Ragtag of Heroes.
Yuuki is a tall young man with a light-brown hair and has brown eyes. He wears a yellow long-sleeved sweater over a white dress shirt, black pants and brown shoes.
Yuuki is rather inconsiderate, and can rarely tell or determine when he has said something that may have been rude or uncalled for. With this, he also does not seem to care much for other's feelings on the outside, though deep down it would appear he is generous as well as passionate for the things he cares for. When given the motivation for anything, he works harder than most of the boys, and will not give up until he has what it is he is after. These rewards usually include manga, which is his one main interest along with video games. In fact, it would seem that these are two of his only interests, as in the first episode of the anime they could not seem to find one single club at school that intrigued him enough to join, despite he is talented in many things (like cooking, Basketball and Judo) he doesn't particularly enjoy any of them, only putting effort into things if there's something in it for him. He constantly makes trouble with his indifferent personality. However in the end, he's convinced by his friends to join the manga club, as mangas are truly his main interest.
Yuuki's lone wolf was toned down. He is more talkative and more cooperative, he has raised his voice multiple times and he is very supportive to his friends.
Yuuki is a strong fighter and often fights with an impassive expression. Yuuki mostly fights with wrestling moves but his true potential is yet to be demonstrated.
