After ending the Genpei War and sealing away the Aion, Benkei settled into life in the modern day. But out of nowhere, he found himself thrown back to the late Heian period.
Benkei and Yoshitsune had a dramatic reunion, but he had lost his memory from the shock of the time slip.
From western Japan all the way to Oshu, the curtain will rise on the Heian Sengoku epic once more.
