After their arrival at the Leukocyte Kingdom, the whole area looks like a RPG with an inn, a weapon shop and well, everything there is in a RPG. As they stop by several shops, they meet a little Tama inside Tama's body and together they head to the castle where they ask the Leukocyte King for aid. But after few minutes it turns out that the King and all the other Leukocyte are in truth Tapir, the enemies. As they try to escape after a battle, they are attacked by the former King, but are saved by the real Leukocyte King who looks just like Gintoki. Then they all together head out to the main castle to destroy the virus.
