Plot
Miu Sakurai is a high-school girl who is ashamed of her childish features, and believes they keep her from being noticed by her crush, Shion Amamiya. After praying in church has no results, she uses an old book she found to read an incantation that grants any wish, not really believing it will work. The spell summons Satan, who demands her virginity as the price of her wish. Miu is reluctant to agree, and tries to avoid him, but he claims he has already granted her wish. The spell doesn't work, however, due to Amamiya's being a Christian, so Satan turns himself into a high schooler named "Kai", and changes the memories of people around her to become her older brother. He also changes his crow Marupasu into a small boy named Tsubasa to be her younger brother. Miu grows confused as Satan continues to both seduce and hurt her, while claiming he will give her Amamiya's heart.

Amamiya's followers are upset by Miu's seeming to grow closer to their idol and bully her. Satan initially watches, intending for Amamiya to rescue her, but when Amamiya doesn't arrive in a timely fashion, he uses his powers to allow Miu to defeat her bullies. Amamiya arrives afterwards and is upset at her use of violence. Despondent and certain Amamiya now hates her, Miu finally gives in to Satan's demands and agrees to give him her virginity. Satan says he will take it on the night Amamiya confesses, then proceeds to help her win Amamiya's love. Along the way, Miu finds her heart thrown into confusion as she develops feelings for Satan.

After school, Satan finds her in the church to begins making love to her, but is surprised to find her crying as she asks if he really will leave her afterwards and begs him to make her forget him.

Amamiya, having realized who Kai really is, breaks into the church and impales Satan with a sword. It is revealed that Amamiya is actual the archangel Michael, the only other person besides God to wound Satan. Having foreseen Satan's coming, Michael had assumed the form of Amamiya in order to wait for him. They battle in the church, and Satan is wounded after Miu tries to stop the fight and protect him. Michael prepares to send Satan back to Hell, but as he collapses he promises to take Miu's heart with him and tells her that he loves her. Miu runs to him and begs him not to leave, pledging her eternal love if he will stay with her. Michael admits defeat as he can not fight love. As he leaves, he says he hopes Satan will return to being the beautiful angel he once was. Alone again, Satan reverts back to his human form to claim Miu, but she faints from the excitement before they can finish.

In the morning, Miu wakes up to find people have forgotten her "brothers" Kai and Tsubasa. At school, she finds that Satan has now become her biology teacher, still using the same name. Tsubasa is now in her class as a high school student and assigned to protect Miu from any danger. Michael/Amamiya summons Sarah, a half angel-half demon, to Earth and tells her about Satan being in love with a human woman. She summons Satan back to hell, infuriating him.

Miu follows but Satan is furious and tells her that he will call the Sabbat, a gathering of demons where he slept with Sarah for show, and that Miu must attend to receive her punishment. There, he calls Miu from the crowd to be his consort and begins to take her in front of the gathering. Crying, she swears she has not betrayed his love, and Satan permanently closes the Sabbat then takes her inside where he makes love to her while calling telling her she is "precious."
