upper and lower

Ok so, this is if Rengoku accepted Akaza's offer of becoming a demon, you play as Rengoku Kyojuro btw. but let's get into the story! STORY: you and Akaza went to the infinity castle, you met all the Uppermoons and lowermoons and what not, Muzan was also willing to give you some of his blood to make you stronger. You are Rank 1- lowermoon because you defeated Emmu(I think that's how you spell it) also, look up what Rengoku would look like as a demon bc I'm tired!
