Ace doesn't have a filter, having no problems discussing anything. Never hides what he's thinking or feeling and is brutally honest. This can make him annoyingly inconsiderate. He's the ace in his basketball team, however his grades are terrible. With a demeanor like his, one would expect him to be an airhead, but he's surprisingly clever. He's brightly cheerful yet mischievous with a penchant for prankly jabs. He stopped being a playboy when he started crushing on his basketball team manager.
