Set during the turbulent Bakumatsu period, this anime brings Edo's streets to life through the eyes of sword warriors tasked with preserving history against forces that seek to rewrite it. The story centers on two humanoid manifestations of Hijikata Toshizo's legendary blades, whose deep connection to the era makes their mission as personal as it is urgent. Fans visiting Tokyo will find resonance in real historical sites tied to the Shinsengumi, the very world this series works so hard to protect.
