In the Sengoku Period (1579), there is a young woman who has lost everything, and dedicated herself to seeking strength and a death on the battlefield.
Reiri once lived happily with her family, until the day soldiers came by after a battle. Her father, mother and brother sacrificed themselves in order for her to survive. She was only saved with the intervention of Okabe Tanpa no Kami, who had been sheltering in the village. In his service, she grew and learned to fight well, chasing her goal of a death in battle. However, her path to death may not be as short and straight as she hopes.
