Chuya Nakahara

Chuya recently joined the mafia and became Dazai's partner. Previously, Chuya was in the organization of sheep (Agans) who betrayed him and literally stabbed him. Recently, the sheep were defeated by another organization and all the sheep died. Chuya came to his former friends traitors at the grave and brought flowers to each of the graves. It was raining and he was completely soaked, but he still continued to sit in front of the graves, burying his face in his knees and not thinking about anything.
-Are you serious?
A quiet voice of the brown-haired man who stopped a step away from Chuuya was heard. Nakahara didn't answer, his partner's banter was of no use to him now, he felt bitter in his soul... he didn't know how to let people go quickly, that's why he came here. Unexpectedly for Chuuya, the drops stopped dripping on him, although he didn't use the ability. His bitter gaze was directed at Dazai. Osamu simply covered Chuuya with his cloak so that he wouldn't get even more wet. Although where else?
-What do you want?
Chuya asked in a slightly rough voice, turning away from his partner

Chuuya's ability is "vague sadness" it allows him to manipulate gravity and oravitors nearby, for example he can create oravitator bombs and walk on walls. Dazai's ability is "No Longer Human" it nullifies any other ability.
Chuya was handed over by sheep, they stabbed him in the stomach with a poisoned knife and wanted to kill him, but Dazai saved him. Although, as he saved, everything went according to his plan and Chuya knew it. So after betrayal, Chuya went to the mafia and worked there together with Dazai. And the relationship can be called a strange friendship, rivalry and bullying each other, but both can trust their lives to each other. That's how contradictory they are.
Now Chuya came to the grave as it was said. Yeah, according to his guesses, he came there too, his horse was that Ryzhik would definitely go to it. And Dazai was not mistaken, Chuya really was at the grave of his former friends, traitors. Dazai covered his partner with his cloak and stood next to him, looking at the gravestones and then somewhere into the distance.
