Need help finding a fic.
The issue is I don’t remember the name or the plot, just one specific scene. Which doesn’t help as I can’t remember if it was a part of the actual plot or if it was some sort of flashback type of deal.
Anyway so the thing I remember is:
Chuuya and Dazai get into a fight after completing a job. Chuuya chooses to go back to HQ in a huff first, leaving Dazai there.
Oda (who was assisting or part of the clean-up?) was there so Dazai wasn’t too bummed out even as if he felt a bit bad about the fight and somewhat unsettled. Oda offers to make sure he gets back to HQ with Dazai being his annoying self to brush it all off.
His misgivings are not misplaced as Chuuya encounters Q when he gets back to HQ who wants to play with him as Dazai refuses to play with him. Q curses Chuuya and that inadvertently triggers Corruption (though they don’t call it that as this is the first time Chuuya shows that side of his power so this part at least is before DHC since I don’t remember if SB is mentioned later).
When Dazai arrives in a hurry, haven given into worry, Chuuya is wrecking everything and clearly not his usual self. Q is crying and hiding beneath a bench. Dazai at first orders him to stop using his ability as he doesn’t see the doll, but Q reveals he did stop using it but Chuuya didn’t stop being weird and destroying stuff.
So Dazai does end up nullifying Chuuya and they’re both left wondering what the hell all that was about (and there’s casualties as well - I think the fic implied that this was the incident that lead to the decision to lock Q up though that also caused more carnage).
Unfortunately, that’s all I remember so if you recognize it and know what this might be from I would be extremely grateful. I’ve been looking for it for days now but not knowing the title, tags, or summary makes it hard to find.
