Well, I originally planned to leave this section blank, but I just wanted to let everyone reading the English version know that the explanations for a few things are in the gallery of the Spanish version. I explained the situation there and why I decided to upload this older doujin instead of one of the newer ones.

If you're curious, just check the comment I left in the Spanish version's gallery. One extra thing I'd like to mention is that I added one additional page to this release. I converted the character measurements to the English system, just in case anyone was interested. If not, you can simply ignore it—it's the exact same final page, just with the measurements converted to a different system (the original Japanese version lists them in centimeters).
By the way, these older doujins didn't actually come with cover pages. Because of that, I made a simple one featuring the title, just to make the release look a bit cleaner and more organized. I simply reused one of the doujin's pages and turned it into a cover, since there wasn't an official cover to use.

As for the three new doujins I mentioned in my comment on the Spanish gallery, they are:

-The video game-themed doujin (the longest one).
-The dungeon-themed doujin (also fairly long).
-The two girls doujin (the shortest one).

Sirosoil is also currently working on another new doujin that's going to be quite long, and it hasn't been uploaded anywhere yet. We'll see which one I end up translating if I have the time.
If you're interested in the latest releases, like I mentioned before, please consider supporting Sirosoil through their official platforms whenever you can.
