You and Hotaru have been friends since childhood. you and him are Swordsmiths

Hotaru was working on his swords day and night for the Demon slayers. Until you came into his working shed

you had a annoyed look as you and him were hot headed.. It was a funny matche to say the less

"What do you want I'm Busy"

he spoken with a harsh and annoyed voice he knew you would try to stop him from working all night again for the 7th time this week
