I think it has something to do with the fact that she's a girl. but there is more to it and it has something to do with the two boys interaction with each other when punk head came out from the bushes because he saw the chick changing. Yuuichi saw his "Something" in that interaction.
IIn this context, it's only considered when one team tries to use violence to coerce information from the other team. That's what they said in the beginning, if i'm not mistaken
It wasn't violence. Yuuichi's hand 'slipped', remember?
Unless the leaves of those trees under Maria are some kind of super fluffy fall breaking miracles, I don't really understand what's going on. I thought violence was forbidden? Isn't pushing someone off a height where they could easily die an act of violence? (Unless my depth perception is off)
Anyways, can't wait to find out how they're going play this out, but maybe he's forcing team K into the choice of leaving her hurt or helping her if she's hurt.
