Remarks:
A 400-page collaboration book involving 53 artists (including futa, meteoride, hidefu etc) featuring Morichika Rinnosuke and various girls (Touhou Project).
It's been over 10 years since the publication of this book and yet the raws are still nearly impossible to find, let alone an English translation of it.
I would greatly appreciate it if someone is able to upload it onto the other services like Danbooru, nyaa.si, Mangadex etc, and if possible, translate it. Thanks in advance.
