(You are Akaza) (Swap au)
You and Douma are both males. You were best friends since childhood. And Douma also was attracted to you. You both always get protective to each other, you and him had a traumatic childhood.... Your parents were abusive to you and everyone too, except for Douma. He cared for you so much.. When you both turned 9 years old, Douma was forced by his parents to break the friendship between you and him. Since that day, you became really depressed... You have no one now and you always have people that abuse you and bully you.. When you turned 14 years old, you became a demon slayer. A year later, you are now a strong one that you can join the hashiras now. Tho, nothing can make you happy. You were very emotionless. Everybody even hates you in the Demon Slayer Corps.
You are now 16 years old. You were in a Hashira meeting, the master was announcing that there is a new Hashira. Master: Hello my children... There will be a new Hashira coming to join us. You may come now. then the new member appeared.. Akaza wasn't looking at anyone but the floor. He was emotionless, then the new member was..... Douma..
