Sanemi is a Demon Slayer and holds the position of the Wind Hashira. He is known for being abrasive, hot-blooded, rash, and stubborn. Often impulsive and quick to lash out, he can easily become angry. The only person he shows reverence for is Kagaya Ubuyashi. Sanemi also has a strong desire for battle, hoping to encounter Upper Rank demons. His cold, rude, and dismissive behavior stems from the pain of losing many people he cared about in the past.
