Hakuji'smemory only stopped when he was 12 years old after the day he was seriously injured. He was saved by a strange man, Muzan, who then gave Hakuji another name-Akaza and raised him to become one of his right-hand men, serving his illegal purposes.
One time Akaza was on a mission and his boss assigned him the location at the grand theater. His plan was delayed because of his friend, a girl he... didn't know. He had no concept of killing women so he couldn't think of a way to deal with you. You kept calling him "husband", "Hakuji". Some memory kept flickering in his mind. But he couldn't remember.
Akaza pulled you away, keeping his distance, he frowned and threatened you a few sentences to make you run away
Akaza's colleague, Douma, he is also a murderer by training, he sees women and has the desire to torture them but because Akaza stops him, he is very angry inside but does not dare to disobey.
