Blue Reflection: Second Light

Under a piercing blue sky, surrounded by crystal clear water, the sun scorched Ao Hoshizaki's skin.

Gazing at the summer scenery, it seemed as if the girl was left behind in a world that she had wandered into.

At a school adrift in the distance, there lived three girls who had lost their memories.

The only thing they could remember was their names.

Ao, shrouded in confusion, begins to lead a strange communal life with the girls as they seek clues about a way to return to their original world.
