This history is very touching and all but i just don't understand one little thing: if kam...

You know that an erection depends on blood too, right? So if we are taking this literally they have a much more serious problem in their hands than blushing.

But they show a "hands-on" approach to solve that one.
(Forgive me, I couldn't resist m (_ _) m)

A "hands-on" tactic could be exhaustively applied but without the blood the result would still be really sad for everybody. Neither them nor us would have any fun. So lets be grateful that mangakas are incredibly inventive and prone to ignore the laws of nature.
(There is nothing to forgive, dear friend, I would have done the same.)

Oh the left side of my brain went on vacation right about when they introduced the "omnipotent ointment". (Don't get me wrong, I love this story to pieces.)
Hence I only shrugged when Waki pulled a fully-grown humanoid out of a bathtub he'd formerly thrown paper. (The magic is strong with that one. *nods* )

I felt a little awkward when the paper turned up to be a dog and I thought "zoofilia?" but then the dog became human and everything was alright. *nods*

But that's exactly why I loved the little extra about Ryusei & Morya delving into the "necrophilia-issue" ~ why should I take this all so serious? They don't, either... ╮(￣▽￣)╭
(It's like every turn the reader might take with the story, the mangaka already "got that covered")

Well, that is what mangakas are for. If I wanted reality I would go and read newspaper! They painstakingly ran their brain trying to create something completely improbable, utopic, crazy, impossible, and so on while entertaining us readers. That is a noble job. I am so grateful to them! m(_ _)m Where else would we find a house full of sexy walking paper dolls, a cute dog/boy paper doll, a family that profits from killing people and still manages to steal our hearts to the point where we cheer for them all to be happy (well, people that can kill other people with only words isn't that common either), and lets not forget the guy that is alive and kicking for centuries, and a kid raised in the basement that loves icecream. A woman that looks more like a guy than the guys themselves. And a "thing" that is big enough to almost hit the knees (poor Kon...or not). I love this manga! It has everything a fujoshi needs!

All in all I rejoice about the fact that I can discuss this leisurely 'here' ~ trying to sum up the story however to intrigue an innocent bystander might drive me to my boundaries ... So "Good Job!" to whoever wrote that summary;
"In the weird house of Wakeari" is really most...suitable.

Weird... Yea, that fits.(●￣(ｴ)￣●)
