Reimu wanted babies, Reimu had babies, didn't like the babies, killed babies. Wow. Really rare that all the babies are just of one type, though. On a side note, tagged some of these strips with shithead as well.
It seems Reimu's mother tried to teach her daughter how to take it easy by doing her part with everyone else. Sadly, she became a deimu instead. I almost feel sorry for her... almost.
I actually think that the mother was a deibu as well, considering she killed some kids for no more reason than they were being noisy, and she might have killed the neighbouring Reimu for what could have been an accident.
