Under a deep blue sky, surrounded by crystal clear water, the sun burned Ao Hoshizaki's skin. Looking at the summer landscape, the girl seemed to be left behind in a lost world.

At a drifting school in the distance lived three girls who had lost their memory, the only thing they remembered was their names.



One day, in this world where the school was surrounded only by water, a path suddenly appeared that led to a new landscape. At the end of the road was a mysterious location, where familiar things inexplicably existed.

To understand the situation, the girls decided to venture ahead, but as soon as they took their first steps, they came across a monster they had never seen before. But just when they thought things had become hopeless, the girls gained a mysterious power.
