In the gripping tale of "Peacemaker Kurogane: Belief," the story centers around Ichimura Tetsunosuke, a young man deeply affected by the horrific murder of his parents at the hands of one of the Choushuu. This traumatic experience carves a void in his heart, igniting within him an unquenchable thirst for revenge. Tetsunosuke's desire for strength begins to manifest as he yearns to protect his family’s honor and restore a semblance of peace in a world rife with chaos and conflict. With each passing day, the weight of his grief fuels his determination to seek out a path that could eventually lead him to confront his family's dark past and the perpetrators of his suffering.
At just 15 years old, Tetsunosuke takes a monumental step by approaching the infamous Shinsengumi, an elite police force known for its unwavering allegiance to justice during Japan’s turbulent Edo period. Driven by a desire to belong and to wield the strength necessary to safeguard those he cares about, he dreams of becoming a member of this storied group. However, he quickly discovers that the road to membership is fraught with challenges. Despite his burning passion, Tetsunosuke grapples with the harsh reality of his own limitations, lacking the skills, mental fortitude, and emotional detachment needed to engage in the brutal life of a Shinsengumi soldier. His youthful idealism clashes with the grim realities of violence and sacrifice that define the era.
Fortunately, Tetsunosuke is not alone in this journey. His older brother, Tatsunosuke, stands firmly by his side, providing unwavering support as Tetsunosuke navigates through the trials of self-discovery and growth. Additionally, he finds camaraderie among his new friends within the Shinsengumi, who will both challenge and inspire him along the way. However, as he progressively integrates into this historical group, Tetsunosuke remains blissfully unaware of the bloodshed and suffering that inevitably accompany their crusade for peace. The path he walks is not just one of valor but also of undeniable pain, forcing him to reconcile his thirst for vengeance with the realities of loyalty, friendship, and the true cost of peace.
