FROM THE MAKERS OF APPLESEED AND VEXILLE - A NEW LEGEND IS BORN.

Ichi is a sole goze (blind woman singer) carrying only a shamisen (Japanese stringed instrument) and a walking stick, traveling on her own to find the man who has brought her up and cared for her as a child. People try to take advantage of the fact that she is blind, but Ichi fights back with her unusual skill with swords, using the sword hidden inside her walking stick. An incident brings her to meet Toma, who tries to save Ichi from the Banki-to gang, but ends up showing his awful skills in swordplay and is saved by Ichi in return. Ichi unwillingly starts traveling together with Toma, and comes upon the village, where the Banki-to gang, led by the inhuman heartless Banki, is taking charge. They also run into Toraji, who is the successor of the Shirakawa yakuza family trying to keep order of the village apart from Banki. Toma offers to help, but Ichi is uninterested, until she finds that Banki might know the man she was looking for. Now the deadly battle is about to begin.
