In a last-ditch effort to lose his virginity and die right after, Takeshi draws a demonic circle in hopes of summoning a succubus to wring him dry. He successfully calls upon one named Miyu, however, she is also a virgin—completely inexperienced with her sole purpose. While Miyu's best efforts to please Takeshi to the point of killing him are not fully effective, perhaps the unity of these two virgins can help them realize their true destinies.

Meanwhile, a man named Shuu has recently moved to a new apartment where he notices a blonde doll sitting above his closet. Following the decision to take care of it out of fear that a curse will befall him if he disposes of it instead, he finds himself brimming with good luck. Eventually, the doll assumes a human form and introduces herself as Nina. As if things could not get any better, she promptly proceeds to alleviate Shuu's sexual desires.
