... until somebody looks at him.
At least he can bear Ryouko looking at him. That's the most important thing, of course.
I can't help but question the wisdom of Ryoushi telling her repeatedly that he's going to always protect her. The girl has used her free time to get better at fighting and is by no means poor at it, so what exactly does it gain to tell her that she needs protecting? Shouldn't he rather tell her that he's going to fight alongside her, no matter againt who? Even if this current form isn't what Ryouko exactly is like and would really want to be, I don't think it would do her much good to suddenly drop the boxing practice and become a meek ordinary little girl. She can't just turn back the clock, nor can he for her.
