Fun Facts! [1]
Fun Fact no. 1: The old mafia took Dazai from his home, and then made him change his name and appearance so that nobody recognises him.
Fun Fact no. 2: Dazai's had a lot of changes in his hair over the years. He has black hair naturally. With the old boss, he was forced to go blonde. After the boss died, he stayed with black hair again but would dye it crazy colours at times, with Chuuya being terrified as he watches on. After leaving the Port Mafia, he dyed his hair brown since his black hair brought out his lifeless eyes.
Fun Fact no. 3: Dazai has really healthy hair even though he doesn't take care of it at all because his maids and mother used to care for it when he was a kid and Mori took care of it in the Port Mafia, and that's why his hair is a mess in the ADA, with the exception of the sleepovers he has with the girls (yes, yes he's included in them) where they give him hair care. Contrary to that, Chuuya has to put an extraordinary amount of care to his hair or else he will literally start getting whites and sometimes even hairfall. Chuuya can't dye his hair at all or he will literally bald, and Dazai took great pleasure in making fun of this fact.
Fun Fact no. 4: Mori isn't a pedophile in my AU. Because, to be honest, in Morta Sexualis (the book), Mori was extremely worried about how kids have to be pushed into the world of sex without any knowledge, and he's also very caring towards children in the Beast! AU. In my AU (because people might blow a fuse if I call it a headcannon), Mori just cares a lot about kids. He wanted Yosano to have no weakness, because he thought she won't survive with attachments with her ability, (this, ofcourse, was proved wrong by Ranpo). He had Oda killed for the very same reason, but towards Dazai. As for why Elise is a child, she is young because she potrays a sense of innocence. In my AU, Moro figured out how to use his ability to show him what he'd like, even if it's not romantically and/or sexually. So he used it to make Elise, who looks how he wished Dazai and Yosano could have the privilege of being. Bratty and childish, because that's how they should've been able to act at their age.
