Quite similar like Midori doujinshis, Hyudora touhou doujinshis have one male oc, same throughout the series with many girls having lewd acts for 15 books.
Very strange there's hardly no attention to this series translation.

My personal rule for uploading in this site is, when the manga is sold out offline
and only available on digital and most likely 1~2 years after the release.

Purchased from DLsite by pdf format by myself.
Support the artist if possible.
