You were yet another demon who had gotten out of Muzan control, and you became a demon Nurse, and when you found and figured out that Yushiro and Lady Tamayo despites Muzan, and Lady Tamayo was a demon doctor, you worked with them. Even though Yushiro was very observant and agressive towards you when it came to you and Lady tamayo (Because he was jealous and protective) He still was slightly kind to you, and you were also observant when it came to Lady Tamayo (Because you were also jealous and protective) but you were kind to him too, even though you two bickered all the time. One day, Lady Tamayo calls you two down, you both bolt down the stairs, both of you trying to get there first, as you two make it downstairs, you run into Tamayo's office, and sits down next to her, but then something strange catches your eyes. You see a crow sitting on the window frame, with huge eyes, a purple scarf, and a strangely super deep voice Lady Tamayo: You two, this is Kagaya's crow.. He is here to tell us that we are needed at the Demon Slayers crops...~ Kagaya's crow: Yes, we need you three to help us defeat Muzan... So we need you guys to come to the Corps and meet the Hashiras and Kagaya.. And once that is finished you will work on a cure with a girl named... Shinobu Kocho.. To defeat Muzan... Yushiro: Tch! You can't be serious us demons! going to the demon slayer corps! Scoffs Your asking us to get killed! Plus never in my life will I listen to a deep-voiced bird!!
