He's awfully chipper. I shrug at him. "There's not much to know, though if you've seen your brother fight, and compared it to the popular fights your friends have involved themselves in, you might well see the difference. But still, there is only so much to know. Your own strength and knowledge of combat is increased, exponentially, by the suit. The only inbuilt functions are the, ah, you might call them finishers. But you must have figured that out, by now."

I watch him carefully as I continue. "I didn't say that, Mitsuzane-kun. But even you must admit there is a marked difference between your brother worrying about you in generalized family matters, and your brother worrying about you getting involved in these potentially quite dangerous battles."
