The 3rd entry of the Infinite Cross series...
This is a story about Justice.

=======================================
On a summer night, an unexpected, yet well-known figure charges into the "Noian Anything Detective Agency", and demands to speak with its owner.

"I may have conducted a terrible mistake."

At another location, a girl wakes up without any recollection of what just happened, and without any clue of who she is, where she's at, and why she's here.

The only clues: An open diary book in front of her, and the weird shrine maiden clothes she's wearing, and the fact that she seems to process an extraordinary memory (yes, ironic, we know) and a great sense of hearing.

Confused, she reads the diary...

"If you are reading this, my plans have been set into motion;"
"The dice has been cast."
"It may be a terrible decision, and probably would prove to be a huge mistake, but that's something I must do, or my years' work would be meaningless."
"Please, forgive me, forgive us."

Such was written on its few pages.

There's no use staying in an empty building, especially for a girl with amnesia, thus, she sets off.

As for the rest of the story, set into this girl's shoes, and play the game to find out.
