In a world where everything has sunk into the sea, protect the ark with big-breasted swimsuit beauties!

A high-tempo defense game with simple controls! The ark "Mobile Oceanic City GFM Oceanus" is inhabited only by big-breasted beauties in swimsuits. The visitor, Neptes, must fight against the [Creatures of the Abyss] who threaten them and uncover the mystery of the [Great Abyssal Goddess].

Prepare for stronger enemies with each wave by selecting cards and upgrading your characters.

Selected cards include passive skills, active skills, parameter level-ups, and heroine upgrades. There are over 60 types of cards!

Each stage features unique mechanics, chance events that can turn the tide of battle, recovery events, and shops. You can also sometimes specify the three attributes of enemies, adapting to your build for an advantage.

The ExArts, which heroines can use at regular intervals, are spectacular! They can change the course of battle!

Even in defeat, you can perform various permanent upgrades at the base! Increasing damage reduction in particular will make the game easier to progress!
