Side story
Soukou Akki Muramasa: Shokuzai Hen


In the first half of 20th century, Rokuhara Shogunate rules Japan with an iron fist of robotic suits of armor called Tsurugi, while the West wants to turn Japan into another military base. A policeman called Kageaki Minato arrives into a city of Kamakura to solve various different cases involving Tsurugi users (or Mushas), and when all other means are proven useless, defeats them with a skillful use of his own Tsurugi, the bloody red Muramasa. But he doesn't do that out of justice. He only wants to atone for his past sins and to defeat the most powerful Musha, one known as the Silver Star.

“The devil I shall meet, the devil I shall cut. The saint I shall meet, the saint I shall cut.”

This is the phrase that Kageaki says when fusing with Muramasa, and this is the phrase that tells both his past and his future…

Classmate of Kazuki. A green haired, ponytailed girl with a short physique and childish face, which often makes her to be confused as a junior high schooler. Younger sister of Wakana, Mika is a prodigy that skipped grades in school. In particular, her forte lies in computer/robot hardwares. Albeit she's bright and energetic, her selfish behavior causes other people to look down on her, thus she don't have many friends. While she's a slow runner, she's good at ball games. Loves dancing, dislikes being treated like a child, and also dislikes carrots/peas.
