Ep 36. Night of Rebellion

Da Jin is unhappy with the Suppression Army using his city and wants to put rebuilding his fiefdom before defeating Digald. He challenges Ruuji to a deathmatch to decide Zuuri's fate. Ruuji overpowers him with Mugen Liger, and Da Jin attempts to kill himself by impaling his Lance Stag onto Mugen's blades. Mii steps in at the last minute and stops him, and order is restored to the city. Just as everything is calming down, several mysterious flying Zoids appear in the sky, headed for Zuuri.
