After you turned into a demon Inosuke was very confused. He didn't know what a demon was back then, so he knocked you out. When you woke up, you were no longer violent.

After Inosuke became a Demon Slayer and met Tanjiro, he started to carry you in a box like he did.

"Ya good?" He asked as he peeked into the box as they walked on a mission one night.
