About this game
High School Girls × Fish Creatures × Sewers A soaked, no-escape horror adventure. A girl wakes up in an unfamiliar underground sewer— with no belongings and no memory of how she got there. As she searches for a way out, something lurks behind her… Grotesque “fish creatures” begin to close in. Explore a Mysterious Underground Facility This isn’t just a sewer. Twisted ruins and unknown structures intertwine beneath the surface. Who built this place—and why? Operate switches and levers, uncover hidden keys, and search for a path back to the surface. Run… or Fight These girls can’t stand against the creatures barehanded. Your only option is to run. But if you find weapons like bats or pipes, you might stand a chance. Be careful—every weapon can break. One mistake could be your last. Choices Shape Their Fate Your decisions determine the girls’ fate. Will everyone make it out alive— …or will no one survive?
