Consumed by negative emotions, Douman is transformed into a giant demon. He now possesses within his body Antenmaru, a demon sealed away over a millennium ago by the desperate efforts of the Ketsuno and Shirino clans. Not even Seimei’s voice can reach to Antenmaru when Gintoki stands before him with his aura-charged wooden sword. How will Gintoki fight the great demon who has returned after a thousand years?!
You don't want Ms. Ketsuno to find out
about this huge fight over her, do you?
No quieren que se entere de la gran 
batalla que se libró por ella, ¿verdad?
Você não quer que ela saiba 
dessa briga enorme por ela, quer?
