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.

If the girls solve the mystery, what will they obtain?

With gorgeous translucent designs by Mel Kishida, as well as a story that depicts the youth of lifelike girls, based on a theme of human identity and bonding, a new title in the BLUE REFLECTION series is here!
