Ouji Hagemashi

About

Hagemashi Ouji is pretty level-headed, but becomes a bit of a fanatic of the girls for a while. He becomes obsessed with their weirdness, and even more frustrated because it seems like he's the only person who notices, despite all his "evidence". He is determined to discover the truth about the girls.
He hates bugs, so is terrified when P-ko lands on his lips. P-ko really loves Ouji, but even if Ouji reciprocates the feelings, he doesn't show it. At a Christmas party, Ouji sat under the mistletoe with P-ko... but he didn't give her a kiss until later, when they were being attacked. And even then, the kiss was an accident, and as soon as it happened, P-ko turned into a cockroach and thoroughly freaked out Ouji.
