@Moridin69: The problem with that is that once they step inside the field, whomever's at the door would hear what's going on. The solution is of course to cast the spell with the volume he chose, and
lock the door. Which is, of course, just the superpower you said.
Mareena also once again proved her status as excess. Carol isn't stupid; she's never done something so stupid as to walk in on a man and a woman in what appears to be a personal, private situation and
stay there, but that's
exactly what Mareena would do. I suppose it's all to beat this dead horse of a misandrist joke that the author seems to favor all of a sudden.
I can't say much that hasn't already been said regarding his interactions with that feminist harem; it's pretty hypocritical, given that they are a harem, too--I have no doubt that the fact that they look up to their master is a product of love (one of them even wants him to do them what
they think Ichinojou's doing to Haru), which Ichinojou and Haru very obviously have for each other. Furthermore, they saw something was happening between the two in their private room, and also chose to stay--and kept the kid with them. This is obviously supposed to be a gag, but how is any of this funny to anyone?
That said, the ugly nun is a special case: she kept mean-mugging Ichinojou, spouting her "enemy of women" business, when he could have bounced her off the walls if he wasn't so nice (as required by this gag). Cracking her knuckles and making threat displays would have surely set Haru off too if she wasn't inebriated--how unfortunate. Characters like that nun really don't get what they deserve enough. I wonder if there's a manga out there in which such characters do get their just deserts.
