A small village known as Biei is about to have a whirlwind hit it in the most unlikely fashion. With three sides raging war across the land of Amahara, Japan, one being magistrates, the other two being clans of their own, Biei is used to the everyday hustle and bustle. What they weren't ready for was the strange foreigner whose appearance would be a mystery even to her...

Awaking in a brothel where she'd been sleeping for upwards of three days after being discovered near the river with a large laceration to the back of her head from falling off the cliff, she has no memories. She doesn't know who she is, where she comes from, or anything else. What she does know is she can speak Japanese fluently, as if it was her native tongue, and that she knows that she blind (to a degree).

After leaving the brothel, and hurting a few guards to do so, she collapses on a bridge near the outskirts of town where she's found by a man. With urging from a young girl, he helps her to the doctor on the outskirts of town where her life will begin again.

As her memories slowly come back, and her true identity becomes known, the three sides target her as a pawn to help them win complete control. Her focus, however, remains on the village itself and what's best for it. She attempts to keep her new friends from becoming part of a building war, all while trying to escape a war she left behind.
