Personality: Kou's the kind of person who's always doing something, be it handling work, reading, running errands, and other such things. He treads the line between extrovert and introvert, though, often never getting too social not too withdrawn. All in all, he's a fairly balanced person who just has a knack for getting things done, one way or the other.
Abilities: Kou can create shockwaves by punching or kicking. In theory, he could also make them by shouting, headbutting people, or other such actions that force the movement of air, but it's mainly punching and kicking. Oh, and he can shoot blasts of air with his hands by putting the latter in the shape of a gun and mimicking the motions thereof, recoil and everything.
Skills: It wouldn't be too far off to call Kou a jack-of-all-trades in regards to day-to-day life; he can cook, clean, and, strangely enough, is pretty good at parkour, just to name a few. He doesn't excel in any given area, but it's not as if he isn't still looking for something he CAN excel at.
Brief Backstory: Kou's just your average high school senior... Except, well, only with the loosest definition of the word 'average' here. He's been abnormally lucky during his life, having had the fortune of randomly winning every minor raffle that he's entered as a kid (which has thus led him to soft-ban himself from entering) and, for some reason, has been particularly lucky when it comes to gacha games of any sort, physical or otherwise. He's been dubbed 'The God of Fortune' by his friends as a result, and they often joke around about how if he does anything luck-based for them, it'll work out. It usually does, but maybe that's just observer bias in the works. Kou learned about parkour when his uncle came from overseas one day and showed him the ropes while the two were waiting around at home; the former sprained an ankle in the process, granted, but the experience was fun enough to make him want to practice more. Granted, a cityscape was pretty dangerous to practice in, but thanks to that very same luck he hasn't had very many injuries. Still hurts, though, but that's beside the point. As a result of this training, though, people occasionally come to him to deliver things, simply because it's much faster to go over buildings than around them. Of course he gets paid for it, though. Sweet slush fund for all those books, games, and sweet, sweet gacha game rolls. ...And obviously food and stuff come on now he's not that much of a fool.
