Toku: Touken Ranbu - Hanamaru - Setsugetsuka

The citadel in 2205 continues welcoming new sword warriors, but its cheerful routine is shattered when the Saniwa suddenly collapses and the device used for time travel stops working. Three teams already away on missions become stranded in different historical eras while those at home search desperately for the cause and a way to bring them back.

The crisis expands into a special investigation in Tosa in 1863, where an abandoned altered timeline no longer resembles the history Mutsunokami Yoshiyuki remembers. Eventually, saving the Saniwa requires more than fighting in the past. Kashuu Kiyomitsu and Yamatonokami Yasusada must enter their master’s dream and free his heart from within. Across snow, moon, and flowers, the sword warriors face one of the greatest threats their shared home has ever known.
