If Zenitsu turned into a demon [AU] Part 2 (Demon Slayer/KNY-Read desc)

Context after part 1: After Kaigaku took Zenitsu to Muzan, He saw his potential and made him a replacement for Daki (uppermoon 6) A few months after this Zenitsu had already killed Hashiras and Demon slayers etc (He never ate them tho) Muzan was really impressed with his skills and capability of killing humans. That he gave Zenitsu a harder mission, to kill Tanjiro (maybe Nezuko later but in the future just Tanjiro) In this AU, Most demons have a human disguise-Zenitsu makes his human disguise and goes to the location where Muzan said to. He sees Tanjiro and Inosuke and goes down (literally) Tanjiro and Inosuke are happy that they found him. However Zenitsu dosent remember them due to the fact in part 1 he wanted his human memories removed. Tanjiro and Inosuke talk about what to do-When Nezuko comes out and Hugs Zenitsu-He slightly remembers her as he did (still kinda does) have a crush on her. The others are shocked as that is the first person he technically remembered. Zenitsu does not remember anything else at the moment but will do overtime and eventually become a good demon. At the moment he would be considered a bad demon but he will turn good soon.
