Kimi Meku Yoru ni Kogarete

At Seiruri Girls School, there are two opposing factions: the "Ruri Gumi," made up of respectable young ladies, and the "Ai Gumi," made up of delinquents with questionable behavior.

Among the Ai-gumi students, Nanase Mitsuki is the one most feared by the Ruri-gumi because of her fierce appearance.
Nanase has mixed feelings about her reputation, until one night when she sees one of the good girls, Yuka Hosho, wandering the streets alone at night…?

This is a sweet and fleeting love story between two people who can only meet at night.
