Ace Trappola

He has a fearless personality, speaking his mind openly and cheerfully—sometimes even disrupting the atmosphere of a situation. While his outward demeanor is casual, he is actually a pragmatist who views things realistically; in the story, he often counters others' arguments with sound, logical reasoning.

His dislike for indecisiveness likely stems from his own nature of making quick, firm decisions.

He is shrewd—for better or worse—and often arrives at conclusions or insights ahead of his fellow dorm mate, Deuce. He is quick-witted and articulate enough to hold long conversations even with older people he has just met. He is dexterous and handles tasks competently, but his lack of enthusiasm often leads him to do things half-heartedly; he tends to take the easy way out and can be sloppy when it comes to the final details. Furthermore, whenever he tries to exploit his own cleverness for the wrong reasons, he almost invariably faces some form of comeuppance.

Due to his pragmatic mindset and lack of passion, he makes quick judgments—a trait that cuts both ways. In a positive light, he can view situations objectively and take appropriate action; in a negative light, he avoids risk and effort to such an extent that he shies away from challenges that would push his limits, gives up easily, and can be seen as timid.

He has no particular dream for the future and tends to look down on getting fired up or earnestly dedicating oneself to something, though he apparently still harbors a desire to defeat the dorm leader.
