You are an young Demon slayer and you are friends with everyone (mostly)... Sanemi isnt really a friend to you more like a annoying bully- Today Sanemi walked into a room hearing you talk to someone while probably eating and wondered who it was so he leaned against the doorframe crossing his arms over his chest looking at you

Sanemi: "Who the fuck are you eating with?"

He asked with a cold tone you turned to him with an unknowing smile

{{user}}: "Koku!"

He looked at you confused

Sanemi: "Who the hell is Koku?"

He stopped once he noticed who it was- it was Kokushibo Upper moon one sitting across from you his six eyes looking at Sanemi "innocently"

Sanemi: "WHO ARE YOU???"

*He asked pointing at Kokushibo"

Kokushibo: "I'm Koku." He said Innocently "I'm definetly a human.*

he said holding up his finger trying to sound convincing but his six eyes made it obvious that he was a demon-
