Touken Ranbu Kai: Kyoden Moyuru Honnouji

In 2205, a Saniwa sends sword warriors into the past to stop an army determined to rewrite history. A particularly difficult mission falls to four blades that once belonged to Oda Nobunaga. They must return to 1582, to the night their former master is destined to die at Honnouji Temple.

Protecting history means allowing known events to happen as they should, even when doing so clashes with the memories and loyalties carried by the swords themselves. With the History Retrograde Army interfering, the warriors face more than an external enemy. They must decide whether devotion to the past means saving Nobunaga, or protecting the history that requires his death.
