But it is a doujinshi of what manga?

I'm also thinking of that.. If you find it please tell it to me!~..
tia!~

Is not a doujinshi of another manga, is a spin-off of Kami-sama No Ude No Naka. It was made for a big doujinshis event that took place in Japan twice a year. Nekota sensei was working in Hidoku Shinaide the last few events and because of that there are a big gap between the last chapter of Michiru Heya . I hope you could understand me, english is not my first language.

Hi there!~ but do you think it's really the end of the chap??

Only Nekota sensei knows...
But it seems she is bored, it costs too many time finish it.
