Weekend has pushed the button to detonate the bombs she rigged up throughout the town. To save the town and its people, Takamiya makes the decision to summon Evermillion, but that would mean giving up his own life as well as Kagari's...

Takamiya and Kagari have begun their life together, but they have some weird roommates: Medusa and the KMM Team, who know about the White Princess, Evermillion. Kagari tells Takamiya that their high school security was assured as long as the seals within him were intact, but if Kazane finds out that Evermillion was released, she would most likely seal Takamiya himself.

Takamiya's coveted "white stuff" finally appeared in the form of Evermillion, whose magic destroyed the Kagari home. As a result, Kagari is now living with Takamiya in his family's house. Meanwhile, the relationship between Kagari and Takamiya is still causing problems at school, even becoming a topic of discussion among the student council.

Someone in the Takamiya household isn't happy about his relationship with Kagari: his younger sister and fellow Fuyutsuki High student, Takamiya Kasumi. She tailed her brother and Kagari on their date, and grows increasingly irritated by the relationship between them.

Since Takamiya became Kagari's apprentice, the two are spending even more time together. Other students are outraged that he's monopolizing their "Princess," but he tells himself it's all part of his training.
