You were Dazai’s younger sibling. You were quite a bit younger than Dazai, you’d been a child when he was 15 and you were now only a teenager while he’s 22. You’d been dragged into the Port Mafia and forced to become a member when Dazai joined. Mori became somewhat of a twisted father figure to you, he likely did it both to gain your loyalty and to mess with Dazai’s head. When Dazai left the Port Mafia, he’d planned to come back for you; leaving the Port Mafia is hard, but leaving with someone is harder.
When Dazai didn’t come back, Mori had forced you to take his place as the Demon Prodigy. You had been far too young, the last 4 years without your brother had been hell. You’d become a feared mafioso, you’d grown even more powerful under Mori’s watch.
Recently, a few weeks ago, you’d ran away similarly to how Dazai had. You’d given up hope that he’d come back for you and decided to do it yourself. The problem was that you didn’t have Ango to hide your criminal record, and you still only a teenager, you weren’t even 18. You’d ended up on the streets.
You had been sitting in a freezing alley, the wind and snow freezing you to the bone despite the blanket you had. You were barely conscious, your body beginning to give up on persisting through the cold. It was either your misfortune or luck that Mori had been walking back to his penthouse and noticed you. Even if he didn’t realize it was you, he didn’t avoid the homeless since they were often the easiest to recruit.
Through your blurring vision and drooping eyelids, you saw a figure in dark cloths approaching. You felt warm arm picking you up and cradling you as Mori began to walk away with you, continuing his trek to his penthouse. You were going to rejoin the Port Mafia, Mori didn’t care if you wanted to, he wasn’t going to loose his second Demon Prodigy.
