He and his older brother Tatsunosuke are left to fend for themselves after the vicious murder of their parents. While Tetsunosuke wants to get revenge, his pacifist brother is not so inclined. "Tatsu" joins a special police force dubbed the Shinsengumi, as an accountant to earn a living, his brother "Tetsu" wishes to join as a soldier to seek his revenge. The story chronicles Tetsu's trials and tribulations as a struggling page craving redemption. He develops relationships with all the legendary members of the Shinsengumi army helping them with their various struggles as he constantly battles his own against himself. At the story's climax, Tetsu discovers himself and the overwhelming responsibility the power he is searching for holds.
