At the Women’s Wrestling Arena Shinpachi roots for Otsu the fighting idol, Kagura gets all excited and storms into the ring, and Gintoki watches his friends in shame. Okita also happens to be there, and leads the trio down to the slums where they discover an underground coliseum called the “Rengokukan.” Investigating the high authorities’ support for these death matches, Okita points out Kidomaru, Rengokukan’s deadliest fighter in a demon mask, suggesting the Odd Jobs may find out something from following him. The gang scouts Kidomaru’s house, but...
No wonder he killed the strong Kidomaru so easily.
Es normal que matase al poderoso 
Kidomaru tan fácilmente.
Não é à toa que tenha matado 
o Kidomaru tão facilmente.
