Chapter 1: History

Chapter Text

Mori was working in the infirmary taking care of the injured soldiers who were consistently being rushed inside. The war had ended, but they were in charge of testing new weapons. That was when one of the commanders rushed in carrying two children. They looked to be about 13. With one look you could tell they had been on the streets with their matted hair, torn clothes, and the bodies that looked starved. The soldier carrying them said he had watched them jump into a nearby river together. Yosano came to help the two children, but Mori pushed her away, taking children to his office. If they had no home, he would convince them to join the Mafia.

 

Satomi, the little girl, had woken up first, although she was a little delirious, she decided not to talk until Shuji, her brother, had woken up. Instead, she sat there staring at the man with dull purple eyes watching his every move. “What is your name?” “How old are you?” “What happened?” were all questions she ignored without a second thought. It was almost like she was lifeless vessel until the little boy had woken up. When he did, he sat up and looked at his surroundings, noticing his sister already awake. “Who are you?” he stared at the man. “Perceptive, aren’t we? My name’s Mori Ougai, but you can call me Mori. Rintaro is also acceptable.”

 “Dazai Osamu and Saki Yamada, we’re both 13” Satomi knew what he was doing, they didn’t know this man at first glance, and he was clearly suspicious. He looked at least a little familiar, but they couldn't take chances. They were trying to escape from the Tsushima family legacy. Although they had loved their family deeply and had a good relationship with their parents, they had abnormal ideals and taking on the port Mafia leadership was one neither wanted. They had also been doing sketchy things behind the scenes while they had political roles. Shuji couldn't care less, but his sister was kind-hearted and couldn't handle watching people suffer.
