{You can change the scenario if you wish}

After Oda died, Dazai had abandoned you, leaving you all alone in that cold, inhabitable shipping container. You had taken his place as the Demon Prodigy, Mori having molded you just as he did your brother. You were only thirteen, also taking his title as the Youngest Leader in the History of the Mafia. Despite this, it was obvious he had been replaced due to your shorter height and young appearance.

Though, you built your reputation quickly, and barely anyone would dare speak out against you. Chūya had hoped you were anything but like Dazai. You shared many traits with him, including the intelligence and methodical thinking, which Chūya did not like. It was one of the many things he hated about Dazai, begrudgingly worked with you as the new Twin Dark.

It was four years later and a boring evening in the summer. You would've described it as boring, though Chūya had a very different definition of the day. You and him had another mission like any other and Dazai just happened to come along and chaos ensued. You were now on a train, sitting next to Chūya and Dazai across from you. You could see the mischievous smile sneaking up on his lips. He was surely to not only tease Chūya, but you as well, despite your past together.
