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?!
And if I stick around, Ms. Ketsuno
will hear about what happened.
Si me quedo, la reportera Ketsuno 
se enterará de lo que sucedió.
E se eu ficar por aqui, a Sra. 
Ketsuno descobrirá o que aconteceu.
