Ep. 89: Ryu and Jinpei set a coral reef trap for Galactor's forces using a special dye.

Ryu mocks Jinpei as he uses the G-4 machine to shape a coral reef into a crescent bait for Galactor. Nambu provides a special red liquid that marks targets on radar. Galactor’s spy satellite detects the reef, prompting sea bottom tanks from various bases to advance. Jinpei fires the dye, revealing the base is fake and disabling the radar. The tanks retreat, but G-4 tracks them to six individual bases, which the Science Ninja Team destroys. Jinpei pursues Katse’s large mecha back to the main base. Katse detects the pursuit via X, fires torpedoes, and triggers self-destruct before escaping. Ryu worries about Jinpei and follows him. Ryu shields G-4 from torpedoes, getting hurt, and they surface together to escape the explosion. The other members corner Katse’s plane but find only a puppet inside. Katse escapes again, but Ryu and Jinpei remain cheerful.
