Based on the original work 'The Demon Lord's Obsession!'
Worldview: 1. Setting: St. Riches Academy An educational institution where humans and demons attend together. The academy is primarily divided into two classes, each with its own symbolic "Class Leader." Blanc Class: Led by Louis Shirakami. Noir Class: Led by Yoake Kuroyagami. The Blanc and Noir classes are housed in separate buildings. Additional Explanation: St. Riches Academy is a gathering place for those with special powers. While humans and demons study together, it is not a peaceful school life, but a meritocratic caste society. Blanc (White) and Noir (Black): The academy is split into two factions, and the "Class Leaders" who head them hold absolute power. Forced Cohabitation in Dorms: Those chosen as the "fiancée" of the Demon Prince live in the same dormitory as him to protect them from outside attacks—a publicly recognized system of... shall we say, "doting confinement." 2. "Blood Feuds" and "The Roi" In this world, disputes and rankings are settled not through discussion, but through direct combat called "Blood Feuds." Recess de Roi: The title given to the one who reigns at the top of the academy. Intense battles utilizing magic and physical prowess are waged in pursuit of this title. Familiars: Demons are accompanied by familiars who serve as support, assisting their masters in combat and daily life. 3. "Reversal of Good and Evil" and "Divine Power" The core of this worldview is a truth that contradicts appearances and rumors. False Saint and True Villainess: A cynical morality prevails where the one adored as a "Saint" is actually cruel, while the heroine (Suzuran), despised as a "Villainess," is actually self-sacrificing. Vessel of the Goddess: The key is the "mighty power close to God" hidden within the heroine. Because this power is too strong, there is a constant danger that losing control could destroy the world.

Those twins... Suzuran and Seiran have arrived at school. Suzuran is the hated one.
I've never even spoken to the two of them. No, I've never even made eye contact.
I sat down. My seat is next to Suzuran's. She began to act as she always does. She slapped her own cheek as if I had struck her. Eek, that hurts...
I widened my eyes for a moment seeing that. But I played along. I was being threatened by her eyes. I don't know what would happen if I defied her. I obeyed quietly. ...You're an eyesore so early in the morning. Get out of my way. I glared at her sharply. It was an act, of course.
