Naoto Kagami is a character from the anime and manga series set in the early Meiji period. He comes from a fishing family in the countryside of the Choshu Domain. His education at the Seizan school and the influence of a teacher from his school days left a deep impression on him, leading him to become a fervent supporter of imperial rule and the expulsion of foreigners. This ideological conviction defines much of his character. He is a skilled ninja who operates as a terrorist, with his primary targets being the Kumo family, the central family of the series. His ultimate goal is to assassinate the Emperor and throw Japan into chaos, a mission he pursues with unwavering dedication. In the story, after the apparent death of Tenka Kumo, the eldest brother of the Kumo family, Kagami allies himself with Chutaro Kumo, the youngest brother, who seeks revenge. Kagami accompanies Chutaro on this path, serving as both a partner and a dark influence on his journey. His personality is characterized by a fanatical commitment to his ideals, a serious and disciplined demeanor, and a readiness to use violence to achieve his ends. He is portrayed as a calculating and dangerous figure whose abilities as a ninja make him a formidable adversary. While his role in the narrative is that of an antagonist and a catalyst for Chutaro's conflict, his motivations stem from his rigid ideological worldview rather than personal malice. His development is largely tied to his influence on the Kumo brothers and his unwavering pursuit of his revolutionary goals, with no significant redemption arc presented in the main storyline.
