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.
