Years ago, astronaut Byakuya left behind precious materials, believing that his son, the scientifically gifted Senkuu, would eventually find them. Currently, Kohaku and Ginrou from the Kingdom of Science have infiltrated the harem of the Petrification Kingdom’s leader with assistance from Amaryllis, a local girl. Initially, their mission proceeds smoothly. Unfortunately, a mistake made by Kohaku and Ginrou causes Minister Ibara and Moz, the island’s strongest warrior, to identify the intruding pair as enemies. To make matters worse, Moz tails Amaryllis when she returns to inform Senkuu of the news, thereby discovering the scientist's secret hideout. However, Moz's agenda does not align with Ibara's; he intends to dethrone the minister and keep the petrification device for himself. If Senkuu plays his cards right, he could gain a powerful ally and win the war once and for all.
