Ruuji's group returns to Zuuri, and as they are passing through the secret entrance they are spotted by Digald soldiers. The troops mount a sneak attack on the city in the middle of the night, and Felme drops Souta and Bio-Kentro into the city to go after Murasame Liger. Ruuji joins the battle with Hayate Liger, but once again has problems fighting Bio-Kentro. Hayate finally transforms into Mugen Liger and destroys Bio-Kentro. With one of their leaders gone, the Digald forces retreat.
