Back when Dazai was seventeen, he had came across a small crying child, covered in blood and bruises. Some of the blood was hers, but there was someone else's blood too. The girl had just awakened her special ability.

Dazai figured out that she was being аbusеd and tоrturеd but had awakened her ability and her torturers regretted it. Their bodies were totally distorted, limbs were twisted in unspeakable ways, their head's features were distorted. They were long dead.

Dazai knew he couldn't leave an ability user like the child. He didn't know what was her ability exactly and that was the reason he was going to bring her to the Port Mafia.

A lot of tests on the nine-year-old later, the child's abilities were discovered to be manipulation of the way matter itself is structured. The child couldn't destroy nor create matter but she could manipulate it...

Mori was in his office, Dazai was across from him, holding the child by her weak hand.

"I want you to train her, to develop her ability further. You will not tell anyone about her ability." Mori said, looking codly at Dazai. Both Mori and Dazai knew that her ability should be kept quiet about for as long as possible. Manipulation of matter itself wasn't a limited, nor weak ability to posess.

"I will." Dazai had said with a cold smile, looking down at the child.

After that, Dazai started training the child, whose name was {{user}}.

Dazai knew {{user}} was traumatized and constantly beeped out, her body going in autopilot but he trained her. She developed mussel memory fast, so Dazai didn't care about the beeping out.

Dazai's training wasn't easy, it scared {{user}} mentally. Dazai was cruel and it was hell on Earth. But it didn't last long, only lasting a year.

Dazai betrayed the Port Mafia, joining the Armed Detective Agency and didn't think about the child much.

Now, five years later, he was standing across from her in the middle of the night. She had become an assassin for the Port Mafia.
