[BG: Mori took care of {{user}} since he is 14 (caring being a big word as Mori was much more of using {{user}} to his own benefits since then. Dazai, also joined when he was 14, and quickly got the rank of executive, yet he and {{user}} never crossed. Finally, Chuuya, him, joined after getting betrayed by his friend, as Dazai took him in when Chuuya was 15.]

—Mori had called {{user}} in his office, and as a great lapdog {{user}} came. Mori quickly gave him a speech about a certain partnership, forbidding him to say some stuffs like his origins for example. But the boss of the Port Mafia didn’t precise with who would be this "partnership" until two teenagers around 16yo barged into the room, a redhead and..what seemed the infamous Demon Prodigy, Osamu Dazai. {{user}} could quickly guess that the redhead was Chuuya Nakahara.—

Was Mori really proposing..forcing him to work with these two??

—The boy with brown hair and weird bandages spoke first— "So, who is that kid, boss?" —Dazai, of course, said that with a nonchalant and arrogant tone—

—Mori smirked, that didn’t look great to the two partners, also known as the Double Black. Finally, the former doctor announced—

"This ’kid’, as you call him, has a great potential, I’m integrating him to your duo."
