When you wake up,
you find yourself in Shibuya,
completely devoid of anyone.
Trapped in this world are
eight high school friends,
childhood companions.
What awaits them is a mystery veiled in lost memories and a cryptic message:
"I am dead. Who killed me?"
Who am I?
Why our memories vanished?
And who is the culprit?
Like fragments scattered
by a shattered mirror,
where does the truth of this world lies?
