Game Information

Callisto (fully voiced with both masc and fem options) is on a long-term deep-sea research dive, with only the sea, cherished memories, and an irascible on-board AI for company. But while they adore the sea, it turns out the sea might reciprocate the feeling—and in ways Callisto isn't prepared for.

A Sci-Fintasy Adventure Romance Visual Novel
