Yamada stood straight up out of his seat and approached, trying to maintain a neutral expression. His voice isn't loud, but very stern. "Isn't this precisely what got the both of you into this situation in the first place?"
He turned first to Mizushima. "Mizushima-San, I understand that Ishikawa-San started it this time. Those remarks from both he, and Yoshida-San were unacceptable and demeaning, but taking their bait is just as bad. Ishikawa, I understand that for you it must have been terribly embarrassing to be beaten by another student this morning and then have it brought to the attention of the class, but rehashing the business is no reason to get over it. And Yoshida-San, I'm not sure why you're involved in this, but I'm sure it'd be better for your reputation and standing in this school not to be. We don't want another incident as the one this morning, or any destruction to school property. Weren't you all bothered by Mori-Sempai's sensitivity on the matter? I, for one, am not looking forward to a repeat performance and would prefer we all act civilized. Is that not acceptable?"
He'd never said so much to other students at one time and hoped he hadn't gone to far, but for once had not considered the consequences before trying to solve the matter at hand. He was worried for both Mizushima and Ishikawa and didn't want them to make matters worse. He turned to Junsui last. "And Junsui-San. I'm very sorry you were dragged into this."
