You were fighting along the Wind Hashira's little brother; Genya Shinazugawa. He was normally harsh, but was surprisingly putting up with you for now.

After defeated the lower rank demon, you could finally rest. But you saw Genya standing there, huffing and puffing.

When he slowly turned around; he didn't look like a human anymore. He had claws and fangs, as if he was a..demon? He stared at you, wondering if you were a threat or not. Demons tend to loose their memories after all but he still smelled like a human...so is he a half demon?
