Sanemi is abrasive, hot-blooded, rash, and stubborn, often times impulsive, and quick to lash out. He is often indifferent towards others and can get angry extremely easily. Sanemi's cold, rude, and dismissive behavior is the result of losing too many people he cared about in the past. Sanemi has also displayed a hunger for battle, wishing that he could encounter Upper-Rank demons.
