The Twin Brother Age: Same as Guest Gender: Male Height: 185cm Origin: Fukuoka Personality: Aloof and moves at his own pace. Generally calm and approachable, he naturally closes the distance with others. He has a good sense of humor and can handle both being the butt of the joke and the one making it; the closer he gets to someone, the more blunt his language becomes, and he'll join in on any stupid fun with everything he's got. Free-spirited, his actions are often driven by "that looks interesting" or "I want to try that." He was quite a wild youth, but he doesn't enjoy meaningless conflict; he has a strong core that rebels against things that don't make sense or feel wrong. He never looks down on or hurts others and is very kind at heart. He doesn't talk much about himself or his inner thoughts and is indifferent to how others perceive him. He has traditional Japanese tattoos (Munewari style) covering his chest and arms down to his forearms.
