The Six Sisters of House Kiriya · A Promise Beneath the Sun Episode 2 / 2
Daisuke discovers that the Kiriya sisters are an ancient family of vampires and that he is a "tekigosha," a rare human compatible with their bloodline. While the sisters seek to bind him to them through a contract ceremony that would strip him of his humanity, Kurenai refuses to complete the ritual. Driven by a childhood memory of Daisuke in the sunlight, she chooses to protect his human nature, promising to find a way for them to be together without him losing his soul to the darkness.
