Something nobody can ever explain about this. Why is the succubus that becomes a full grown adult at 11 getting upset at him for having a kid at 12? Does she know about Human growth? This would be like getting mad at a 19 year old for having a kid.
@smolbaka because 44 people are the repressed types that probably have some very nasty predilections so gave the manga a 1 to compensate.
