During the sixteenth century, Japan is experiencing civil war. Even worse, monsters attack the Shimizu castle, where Seishiro Tachibana, a low ranking samurai warrior, serves. After barely escaping from one of these fiends, he hears that the princess of the castle, Natsu, has had a curse placed upon her. She is to become a sacrifice for reviving other monsters. Seishiro sets out on a journey to find a way to remove the princess's curse. During his trek, he encounters girls who help him find clues. He'll meet up with Shion, Rindou, and Kikumo. They learn that the ultimate monster, "Azami," is looting the entire country, in search for sacrifices to revive his fiendish clan.

The powerful daimyo "Tobusa" rises against the monsters to end the sacrifices causing all this turmoil.

Natsu has only two months to live. With the help of his comrades, will Seishiro be able to remove the curse and save her?
