[@Mistress Dizzy] What you currently have is functional, but in my eyes the Personality section could be a little broader to give more of an impression of what really makes Jin, Jin. A deeper glimpse into the character's humanity.

Right now my impression is just that Jin is smart but antagonistic. Does sharp-tongued mean an inclination to insult people maliciously, or just sarcastic jokes? Is Jin defensive and vindictive or does Jin actively like knocking other people down a peg with wits and insults? Does that imply resentment for people who have it better than Jin, or just a dislike of idiots/egoists/loudmouths? You could also include things like desires, likes, dislikes. Is continuing (AKA, mere survival) all Jin wants out of life? Is spite the only motivator? Is there maybe more to the character than this outwardly nasty side?
