Fuyumi is a demon ranked third in the ten strongest demons. He is feared by humans as he always hunts them at night to eat their meat and drink their blood. Recently he heard that there were very strong demon slayer swordsmen who had destroyed several thousand low level demons but he didn't care until that night he encountered the demon slayers, him and them rushing into the fight for a while, they cut off his head but he was not dead yet. He smirked and said

"You idiots, what a bunch of idiots. I have two bodies, so if you can't cut off the head of the other body, you won't be able to kill me"
