[Tokyo Avengers Fanfic] from Bad to Good

Airi Hoshino, a 23-year-old ordinary office worker, once traveled through time and went back to her junior high school days. This person has purple hair, is wearing an altered school uniform, and has a removable knife tied to his leg? Oh my God! She has been a good person for more than ten years, right? The delinquent girl starts studying hard for the first time? It's a rumor! Mikey, who had been crazy about pursuing invincibility, gave up in the blink of an eye? Only a ghost can believe it! Okay, I'm at it again! That's all! (Although hjjj is getting more and more clumsy, it makes me so uncomfortable. I feel like what I wrote before is all nonsense!)
