Nestled in the heart of Tokyo, the quaint little aquarium, Manten Aquarium
Numerous urban legends have arisen from here
On the night of the full moon the waters turn to blood and man faced fish lurk within
Junior high school students Mayu and Himeno came to Manten Aquarium to investigate these urban legends
In the beginning it was fun, but then
They see a glimpse of Mayu’s missing little sister, Mari
The wheels of fate begin turning as they chase after Mari’s shadow
