How many Bishojo Hyoryuki? 15! No more, no less.

In the December issue of adult PC gaming magazine BugBug, it was announced that adult game designer Takahiro (Kimi ga Aruji de Shitsuji ga Ore de) and Kazuya Kuroda's (Vandread character designer) 15 Bishojo Hyoryuki (15 Beautiful Girls Adrift) franchise will be expanded into an OVA release.

The premise behind 15 Bishojo Hyoryuki is that of an adult-oriented parody of Jules Verne's Two Years' Vacation (15 Shonen Hyoryuki, or 15 Boys Adrift in Japan.) The story itself is centered on 15 pretty girls stranded on a deserted island.

At this point, there is no confirmation as to whether the 15 Bishojo Hyoryuki OVA will be an adult release or simply a racy mainstream adaptation.
