Technically since Wednesday is a female, this makes Dazai trans so Wednesday will be going by he/him pronouns, as they are past dazai in this.
Bit of this AU;
Wednesday's parents died mysteriously, and Uncle Fester needed to take care of the children. But since Fester was on the run from the police, he needed to constantly move from place to place. He left Wednesday and Pugsley with his friend, Mori, so that they wouldn't be taken away for helping Fester if he were to get caught. Pugsley quickly became irrelevant as he had no ability and Wednesday quickly the Mafia's Executive and the right hand man of Mori. Wednesday eventually found out he was transgender and Mori had Wednesday's name changed to Osamu Dazai.
