R15 version downloaded from the booth.pm shop. Game is switchable between Japanese, Chinese & English.

I repacked the zip into a self-extracting solid RAR5 archive to eke a bit more compression out of it (and make it easier to open for people who can't into rar files).

----There is no R18 version of this----

This is a short prequel to the vol.1 that was released at the previous Comiket.
