A debate show that has gathered 100 otaku is on the air. Shinpachi, the captain of the Tsu Terakado Fan Club, is amongst the participants. As everyone gets into a heated argument over their beliefs, one man has a fierce dispute with Shinpachi. That man is Hijikata who was driven out of the Shinsengumi after being turned into an otaku by the demon sword's curse. Confronted by a completely different Hijikata, Gintoki and the others learn the demon sword's terrifying past. Meanwhile, Ito has quickly gained power within the Shinsengumi and the squad members are starting to give off threatening vibes.
I heard that you two knew each other
before the Shinsengumi was formed.
Oí que se conocían desde antes 
de que se formase el Shinsengumi.
Fiquei sabendo que vocês se conhecem 
antes mesmo da formação do Shinsengumi.
