Gotta say, this is the second comic I've ever read that has a line about a penis in their heart. Not sure what to make of that fact, but it sure is strange.
The other one, I can't remember, but I think it is a completed series that was being worked on during the same period as the one about the baby Beelzebub comic. Think it was also said by a girl with a bag on her head on the roof of the school (not Jitsu Wa Watashi Wa, another bag girl).
