Anri won't attack Yuri unless he seriously provokes her, but provoking her will be a bit easier than normal. She's pretty much at the end of her rope in general, sob, so it may be more -- huge emotional breakdown than actually attacking anyone. Does that make sense? I can't think of any reason why he would make her so angry she'd want to attack him, especially since she almost never gets angry.
Yay poker game! Does it count as strip when they both barely wear clothes to begin with? :D
