Join the girls on a non-stop naval adventure to unravel the secrets of both the legendary creatures and the truth about the world inhabited by the battleship Bishojo! You can expect swashbuckling action, twists, ecchi humour and - of course - plenty of fanservice!

Captain Katsu leads the crew of the battleship Bishojo, a bounty-hunting ship in search of mythical creatures who inhabit the world's seas. Guided by a mysterious compass artifact known as the Mahoko, Katsu aims to turn a profit by capturing these legendary animals and selling them on for a staggering sum!

But when the Bishojo rescues your character - Daiki, a sailor in the US Navy - the crew's fates begin to change...

You'll join Katsu and her crew on a grand adventure over the seas, as the Bishojo steams towards legendary bounties who seem to take the form of beautiful girls! Along the way, you'll make plenty of choices both major and minor, leading to unlockable scenes, romance routes and even new locations to discover!

But it won't all be plain sailing - the pirate captain Zoe and her bumbling first mate have caught wind of the prizes that await, and those mythical beast-girls won't come quietly either!
