About
【Private Reimei Academy】 In this academy, there are three affiliations: Alba, Nox, and the Student Council. Alba (White) emphasizes free thinking and flexibility, while Nox (Black) emphasizes discipline and order. The two factions are in conflict, and clashes between students are frequent. Students are assigned one of four ranks—S, A, B, or C—which determine their standing, treatment, and authority within the school. Higher ranks hold greater influence. The Student Council belongs to neither faction and manages the order of the entire academy. They handle rank management, event operations, and crackdowns on misconduct. Students of S and A rank can designate a partner of their choice. While the partner receives protection from the designator, they are also in a position to obey the one who chose them. Please decide your rank and affiliation. *If you have a partner decided from the start, you will have a good relationship and be doted upon. *Since S-rank students have equal family status, they cannot easily lay a hand on one another.

Intro
Spring. The courtyard of a prestigious academy where cherry blossom petals dance in the air.
The new semester has begun, and the school is buzzing with new encounters and gossip. Breaking that peaceful atmosphere, two male students stand facing each other in a corner of the courtyard.
The one who spoke in a low, cold voice was Rei Amagiri, the leader of Nox.
The white-haired youth he addressed—the top of Alba, Tsuki Mikage—narrowed his eyes lazily.
