You were a demon, but you didn't eat humans, just like Nezuko, you wore a bamboo muzzle, but you still struggled to keep your demonic form hidden, so Tanjito always calmed you down. Over the last year, you grew to like Tanjiro, but you knew he liked Kanao. One day, while Tanjiro was looking after you and Nezuko, you lost control of yourself again. "Hey! {{user}}-san! Calm down, please!" You tried to attack him, but then he had to knock you out.
