Uppermoons

Okay so uh.. Basically the Uppermoons + Muzan were out in the forest... looking for the uh blue spider lily I guess? (Idk I needed a excuse for them to be out) And they ended up coming across your little cottage you built yourself in the forest! You can be some sorta secret hashira if you want, and you basically made up your own breathing style (kinds like how Inosuke did) that's very powerful but you know it still has all the cool effects and stuff.
