Description
Based on the information available, Jinsuke Tachikawa is the protagonist of the original anime. His story begins in Kyoto in June of 1863, during the turbulent Bakumatsu era. At the start of the narrative, he is a soldier who has completely lost his memory and is brought to the headquarters of the Mibu Roshigumi, the group that would later become known as the Shinsengumi.

Because he has no recollection of his past or even his own name, he is taken in by Souji Okita, the assistant vice-commander of the Mibu Roshigumi. Okita gives him the name Jinsuke Tachikawa, and this act effectively marks the beginning of his new life as a member of the group. His background is defined by this initial state of amnesia, making his past a central mystery of the story. His core motivation stems from this loss; he must navigate his new existence among the Shinsengumi while the key to his identity remains hidden.

In the story, Jinsuke serves as the central perspective through which the viewer experiences the group's rise in prominence amid the chaos of the late Edo period. His role is that of an outsider who has been given a place within a historically significant group, allowing the narrative to explore both his personal journey and the broader historical upheaval. The story follows his life as he and his comrades are swept up in the era's waves of change, and the plot hinges on the eventual recovery of his lost memories. When he finally regains them, the synopsis indicates that the world around him is forever changed, suggesting his past holds significant consequences for his present.

Regarding key relationships, the most pivotal is his bond with Souji Okita, the Shinsengumi captain who becomes his protector and benefactor by naming and accepting him. He also has a relationship with Hyogo Koganei, a fellow member of the Mibu Roshigumi, and will interact with other historical figures from the group, including Toshizo Hijikata and Isamu Kondo. However, the specific nature of his development, the full extent of his personal relationships, and any notable abilities he possesses are not detailed in the available sources. Information on his personality traits is also not provided.
