At the beginning of the episode, Yuzuriha and Chrome are successfully revived by the Kingdom of Science. Yuzuriha's craftsmanship and Chrome's intuition make them valuable additions to the team. They are immediately tasked with building the drone, which marks the beginning of a three-dimensional conflict with the Petrification Kingdom.

Ukyo, a former sonar operator, is also revived. He insists on obtaining information about the enemy. At this moment, Amaryllis arrives with crucial information from Kohaku about the Medusa, confirming that it operates based on scientific principles. The team begins analyzing the enemy's abilities and internal affairs.

Suddenly, Moz appears, the strongest warrior of the Petrification Kingdom. He has followed Amaryllis and confronts the Kingdom of Science. Gen, the mentalist, takes charge of negotiations with Moz. Through a series of psychological techniques, Gen succeeds in steering the conversation from a potential battle into a partnership.

Moz reveals that he is not loyal to Ibara, the current ruler of the Petrification Kingdom, and is willing to overthrow him. Both parties realize their interests align: Moz wants control of the island, while the Kingdom of Science wants the Medusa. They agree to cooperate, albeit cautiously, as they know Moz might betray them later.

The episode ends with Moz launching a nighttime attack on his own people to make them believe the Kingdom of Science is a formidable enemy. This is part of a larger strategy to force the enemy to reveal the Medusa.
