[Well, that was unexpected. Given that this was Eichi, the hit at the very least earns a light and surprised "Oof" from Madara, but it isn't like it hurt that much, nor did he really flinch or budge.

Okay, now this was just kind of weird? Madara didn't even do anything yet, why was Eichi already resorting to violence? It's so weird that rather than returning the hit tenfold now that the Laws of That Land were not holding him back, Madara responds less violently. With both hands, he casually lifts the Student Council President off the ground, holding him out at arms length like an unruly puppy, a frown mixed with concern and bewilderment.]

Hmm... You're not usually this direct with your thirst for blood, Eichi-san? Did you hit yourself on the head or something? Ah, but if you did, you'd probably just die on the spot wouldn't you? [On closer study, it doesn't seem like he suffered any injuries? He's in irritatingly pristine condition.] What could it be, then? Come on, you can tell Mama.

[Or not. Either way, Madara would rather hit him when he's being himself. For now, anyway.]
