Suddenly, Taku Shimamura, a high school student, finds himself thrust into the surreal world of Slaffleaze. This place is governed by highly intelligent creatures, headed by the nefarious Zolba, and they are hatching a plan to invade Earth, which they refer to as Capricorn. Collaborating with the downtrodden Slaffleaze peasants, Taku embarks on a quest to thwart Zolba's evil machinations before they find their way to unsuspecting Earth. But before he can do that, he must earn the trust and affection of the last surviving Yappie, Slaffleaze's ancestral guardians. This, however, is not a simple task because the female Yappie happens to be a dragon, making it a daring mission that requires a great deal of courage.
