Well, the thing is when he turns his back the main guy looks then does his damage. Sempai does keiko the same time we do and when he does sit on the side and watch the main person tones it down just enough to not have an intervention. There is a serious problem with their behavior, I'm at work right now but I did go ahead and call my sempai to talk with him about this but I had to leave a messege I just don't want him to think badly of me I just don't want to see the younger students get hurt, I tell one of the other young kids to just watch him and not fight against him thankfully he takes my advice, gladly.
