Odc. 40: Jigokiller atakuje kanalizację, podczas gdy Ken szuka Jun, a Nambu odkrywa ich słabość.

40

Jinpei is lost in mourning in Jun's empty shop. Elsewhere, Nambu is absorbed with the research on the Jigokiller plants. Hidden in the sewer, the Jigokiller plants start their activities and many damage reports follow. Ken refuses the order to move out, driven by the remorse that he abandoned Jun. Red Impulse beats into him the importance of the responsibility that it's up to him to at least find her body if Jun is dead. Ken's bracelet receives a bird scramble signal. Despite the fact that it might be a trap, the Science Ninja Team is mobilized. Willy City is well equipped with sewers. They locate the bird scramble in a subterranean base. It is ideal for the Jigokiller plants, since they're weak in the sun and they grow in darkness and water. Breaking into the base, they are barely able to rescue Jun who is bound to a scaffold. Meanwhile, Nambu discovers by coincidence that his blood causes the Jigokiller plan to wither. Because of this, he finds out that the plant cannot stand the Y-chromosome that every man has. He entrusts Red Impulse with a special Y-chromosome bomb. Because of the bomb dropped by Red Impulse, a Y-Chromosome rain is falling and each of the Jigokiller plants wither. The crisis of humankind is over. (Source: Wikipedia)
