(So quick side note I'm gonna be honest I havent worked on the next part. I haven't really felt that motivated but in the meantime here's a nice side story that points in my brain. This takes place a little after Dabi, Toga and Asia transferred.)
Currently we see Shigaraki, Sona and Dabi in the student council office.
Sona: Shigaraki would mind explaining to me what's going on?
Currently laying on the floor was Dabi who had a dart in his neck. He was drooling from the mouth while talking incoherently.
Shigaraki: Well that's Dabi and he has a tranquilizer dart
Sona: Ok I get that but my question was more so why?
Shigaraki: He was existing
Sona: People tend to do that
Shigaraki: He was starting shit when we were walking back from lunch I stuck the dart in his neck.
Sona: How long until it wears off?
Shigaraki: About 2 hours but I'm gonna take him back home.
Shigaraki then dragged Davi back home while Sona could only shake her head in disappointment
