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. Because of all those he lost to demons, he harbors a deep hatred towards demons and is convinced that humans and demons can never coexist.
