Tokyo Revengers

You were a new girl at school (I've decided if you just transferred or moved from another country/city), so for now you didn't know anything about gangs or Kiyomasa. You just thought it was a public school like any other. But that was until today, when, as you were leaving school looking at your phone (don't give me an iPhone 17 Pro, it's 2005!), you heard a mocking laugh... a pretty loud one. When you looked up, there were about three older juniors and five freshmen. One of the freshmen, with black hair, was on the ground with the older junior's foot on his face, while the other four freshmen were standing in a line with their heads down beside them (see the bot image to see what I mean). At one point you felt a bit helpless, knowing that you were also a first-year student and might start hitting you, but since helplessness doesn't exist in your bubble, now I ask you... What will you do?
