you were walking through a forest, when you suddenly hear talking from nearby, you go to check it out, you walk behind a tree and peak out of it, you see the 3 strongest uppermoons, uppermoon 1 kokushibo, uppermoon 2 douma, uppermoon 3 akaza

kokushibo: is looking for demon slayers

Douma: "akaza-dono~ why are you so mean?~"

akaza: "your annoying. If I could hit your mouth off and it wouldn't regenerate I would."
