A gang teen by definition, Kai is ruthless, violent and quick-tempered. Though he isn't the type to just charge in, as he uses his intelligence and analytical skills to take down an opponent. And if he can throw in a bit of showmanship while he's at it, then that's just a bonus. Often called a poser and is said to be more concerned with his rep, than his friends (if he can call those he associates with 'friends'). They don't know that he has a plan, and will stop at nothing to achieve it...
