To confront a great evil, three organizations of justice selected their respective aces and formed a dream team. One day, Dino Tops, Cosmo Red, and Magna Pink joined forces to pursue the villain Gushion from Negastia, but a new threat emerges—the beautiful demon executive Velmaria from the Demon Empire. Velmaria effortlessly defeats the villain and captures the trio, dragging them into the demon realm. While tormenting Dino Tops and the others, Velmaria proposes a wager as the condition for their release: Dino Tops must endure ten days of her sexual torture without ejaculating. Dino Tops accepts the challenge and manages to hold back until the final day. However, just then, his former comrades—now enslaved by Velmaria—appear, plunging Dino Tops into despair. Overwhelmed, Velmaria intensifies her torment, and Dino Tops finally loses control, ejaculating and thereby swearing loyalty to her. As his first command, he is ordered to execute his former ally, Magna Pink... [BAD END]
