Akio Tsuchiya (土屋昭夫, Tsuchiya Akio), commonly known by his stage name King Arthur or simply Arthur, is a spirtually aware Human who has attained special powers, he is also the ex-boyfriend of Marise Asahina. He is also the lead vocalist of his band, King Arthur's Court.
Akio is a handsome young man with messy blonde hair and chocolate brown eyes, and is fairly tall. He has an unusual and intricate tattoo pattern on his arm. His attire usually consists of a dress shirt with casual pants. At other times though, when he is either performing or chooses a day to relax, he's seen to dress more loosely.
Akio is a very haughty man who thinks that the whole world revolves around him. (Or at least should). He also believes that he's very smooth with the ladies and constantly flirts with anything wearing a skirt. He's known to be extremely lazy and will usually convince other people to do things for him. He's not very trusting and is even less loyal, as seen when he immediately leaves his childhood band to become famous in Tokyo. Akio is caring when he chooses to be although he doesn't like to show it. He truly enjoys singing and loves to eat as well, there has not been a single food he has come across in which he didn't enjoy it.
