The fourth battle of Wakayama Castle is between Ichinotani Tenma and Anayama Kosuke.  Anayama says "Justice" a lot.  He attacks Tenma with his warped sense of justice.  A badly wounded Tenma continues to fight, hoping for just one thing: to meet the father and mother he's never seen.
I'll defeat the Insect-men!
¡Derrotaré a los hombres-insecto!
¡Derrotaremos a los Hombres Insectos!
Eu derrotarei os Homens-Inseto!
