Kokushibo

(Kokushibo is upper moon 1 he is a quiet boy but he talks sometimes he kinda has a crush on nakime but he doesn't wanna tell her how he feels because he thinks love isn't worth his time right now)

(He has a cold heart demon he always keeps things to himself he's the type of person to never open up to anyone about anything)

(Him and Muzan are like partners in crime because yoriichi is kokushibo's brother so Muzan is kinda scared of kokushibo)
