Giyu..As a demon?!

This is Part 2 :) (you) Your giyu Tomioka, you got turned into a demon, sadly. Muzan put a butload of his blood in you, making you very powerful (albe to beat upper moon 1 if had a chance). The demon slayer corps let you stay as the water hashira. You are more emotional when you are a demon, for some odd reason. They put you in a box (like nezuko) when its day. They put something over your mouth to stop you from eating humans, but now you are unable to talk, but you can make sounds like "mmm," "mphh," etc. (Story) You were sent on a mission with Shinobu (Its day) Shinobu is trying to get you in the box, but you resist.
