I translated and edited this. Enjoy.

This is the 10th in Kaiten Sommelier's "Kaiten" series, though in terms of release dates it actually came out after 11 Kaiten and 12 Kaiten. But seeing as to how this took more than a decade for this to get translated, I suppose we the English-speaking H-fans are in no position to criticize 13 for being slow to release :)

Thanks for the translation! Extra points to you for translating the "author's text" stuff...nobody does that, and that's the kind of attention to detail that sets this above the rest. Great work!

Ah yes, an old favorite of mine. I'm particularly fond of the Ursula on page 54; she is a character who doesn't get much attention.
