Published by Fujimi Comics in 1996.

There was a gallery with the two volumes mixed together, but it had been taken down since. I sorted all the pages, renamed them with the real page number, and here it comes. This volume should be complete, as it has the side stories chapters featuring another girl, Yukika.

English version has many comic book releases, the part corresponding to this book starts there: https://e-hentai.org/g/21520/f0e0d2f6df/
