Rin and Umi are going to rest over the mountain range, but they're not alone.
Scanned by me.
So long after the low-resolution scan came out, but no one scans a better version.
So here is a high-resolution scan!

There is even some x-ray internal view in this one. There are three creampie endings, that are nicely visible on p. 10, p. 13 and p. 19. Excellent, I like this very much. Thanks for this upload!

On top of Alp's art being really good, I love their mind break/drug-related scenarios. And in that regard, this book is one of their best.

Rin's stories of Alp are godlike.

You mean. "Alp's stories of Rin are godlike".

One question remains: where was Nozomi?
