Kimi Meku Yoru ni Kogarete

At Seiruri Girls School, two groups stand in opposition: the "Ruri Gumi," composed of well-mannered students, and the "Ai Gumi," consisting of students with rebellious behavior. Within the Ai Gumi, Nanase Mitsuki is particularly feared by the Ruri Gumi due to her intimidating presence. Nanase feels conflicted about this reputation until she encounters Yuka Hosho, a member of the Ruri Gumi, walking alone in the streets at night. This leads to a brief romantic connection between the two, who can only be together during the night.
