Cynical and aloof, Ace is a natural trickster who tends to make more fun of things than he should. This powerful lack of faith is driven by a core issue, residing mostly on how the man cannot fathom to believe most of the people he meets or the situations he sees unfold, born from a selfish desire to not compromise to anything. Easier said than done, as one cannot just as easily up and leave their responsibilities. A large fan and advocate of entropy, he shuns anything resembling order or laws, believing them chains that only hold someone's basic desires back.
In other, shorter words, Ace avoids creating expectations from others or formulating hopeful impressions of himself. He shows what he is and that is all that he can do to alleviate any undeserved imagery people form of him. This brutal and cold honesty makes him more enemies than he accounts for, were he to elaborate, but you would also quickly learn that Ace's enemies don't tend to remain his enemies for too long.
Despite that, the man does not have only bad traits. His bravery and willingness to do that which others may not, as well as his experience with the criminal world renders him very much resistant, if not immune to the ailments of the mind. He does not linger about in bloody imaginations or machinations, and instead strides forward not mattering what he went through. Driving himself through the mud and blood is something he has done ore often than he cares to remind himself, and he will do it as many times as it takes until he can rest easy with his chaotic life.
