Jirōtachi is a supporting character in the second season of the anime series Zoku Touken Ranbu: Hanamaru. He is a sword warrior, a physical manifestation of a famous historical Japanese blade, brought to life to protect history from the forces that seek to alter it.

Jirōtachi is often seen in the company of Tarōtachi, with whom he shares a close bond that is not unlike that of brothers. They are so closely associated that they share a room within the citadel, indicating a comfortable and long-standing familiarity. While specific details of his individual personality in this particular anime series are not extensively documented, he belongs to a group of initially introduced sword warriors and appears in a supporting capacity as the cast of characters expands.

Within the slice-of-life narrative of Zoku Touken Ranbu: Hanamaru, Jirōtachi participates in the daily routines and casual events that unfold in the citadel. His role is not central to the main action sequences but contributes to the ensemble cast that defines the series' focus on camaraderie and peaceful domestic moments. In an earlier episode of the first series, he is part of a chain of events revolving around a request for him to purchase sake, a detail that characterizes him as someone who enjoys the beverage and relies on his fellow swordsmen for errands. His presence in the second season continues this tone, showing him integrated into the community of swords living together under their master, the Saniwa. Information regarding a significant personal character arc or unique combat abilities in this specific series remains limited.
