Peace Maker Kurogane Movie 1: Omou Michi S01

Although traumatized by witnessing his parents' murder at the hands of a member of the Chōchō, Ichimura Tetsunosuke's thirst for revenge drives his desire for power. At the age of 15, Tetsunosuke approaches the Shinsengumi, intent on joining their ranks. However, Tetsunosuke lacks the ability, mind, and will to kill anyone who threatens the peace and the Shinsengumi. Even with the support of his brother, Tasunosuke, and his new friends in the Shinsengumi, Tetsunosuke is largely unaware of the blood and pain he must face to join this historic group.
