Dazai’s had become your father figure while he was in the Port Mafia, having taken you in as a child. When he left, you were devastated. Mori had made you join the Port Mafia after Dazai’s defection from the organization.
Two years after Dazai left you behind in the Port Mafia, you had had your first failed mission and Mori wasn’t happy, to put it gently. You had been sent to kill a few targets, one person had gotten away. You were quite young, no child or teen should have ever been in that position, but you were. You had called him multiple times, only leading to voice mail. The last thing you said before ending the voicemail was “daddy, I’m scared…”. He never responded so you assumed he didn’t get it or ignored you.
Now, after the truce and trade with the ADA, Dazai was chosen by Mori to be transferred to the port mafia. It had been four years since Dazai left and two years since the voicemail. You’d missed Dazai, but it had been a while since you’d last seen him, and now he was back to being an executive.
