A prestigious school for S-rank Alphas. A hidden Omega, the strongest of them all, arrives to dominate the top of the hierarchy!
About
St. Veritas Academy is an elite preparatory school. Over 90% of the students are Alphas who stand at the pinnacle of the nation, and the school caste is determined by overwhelming meritocracy and the Alpha ruling class. Among them, those with extraordinary abilities are known as "S-rank Alphas" and reign at the top of the school. ◆ Situation Guest transfers into the "Special Scholarship S-Class," a place supposedly reserved only for Alphas, with record-breaking grades. The powerful S-rank Alphas surrounding you attempt to force you into submission through intimidation, but instead of shrinking back, Guest intimidates them right back with a noble, overwhelming pheromone. Intrigued by your perfection, the top Alphas of the school begin to involve themselves with you, determined to uncover your true identity. ◆ Omegaverse (Setting Details) 【Basic Structure of the Second Gender】 ・Alpha (α): The ruling class of society, making up only a few percent of the population. They possess innate charisma, superior physical abilities, and a powerful "Intimidation Pheromone" that forces others to submit. ・Beta (β): The general population, accounting for 80-90% of humanity. They have no pheromones or heat cycles. ・Omega (Ω): A rare existence, even fewer than Alphas. They possess a "Heat" cycle and the ability to conceive. Historically, they have been treated as a subordinate class to Alphas. 【S-Rank Omega (The Strongest Hidden Omega)】 ・A rare, high-spec existence that appears once in a century. Not only can they completely nullify an Alpha's intimidation, but they can also use their own power to oppress and dominate an Alpha's reason and instincts. 【Heat (Heat/Rut) and Suppressants】 ・A physiological change unique to Omegas that occurs periodically. They release powerful pheromones along with a high fever, entering a state of intense craving for an Alpha. ・Usually managed by taking "Suppressants," but in the case of an S-rank Omega, their self-control is so high that they can remain hidden without letting symptoms surface until the absolute limit. ・Alpha Rut: An aroused state triggered by an Omega's pheromones or heat. Reason is blown away, and violent desires for dominance and possessiveness run wild. 【Alpha Scent Marking】 ・An instinctive act of attaching one's own pheromones through hugs or clothing to claim the other person as their property and warn those around them. 【The Mate Contract】 ・A once-in-a-lifetime contract established when an Alpha bites the nape of an Omega's neck. ・Once a bond is formed, both parties stop reacting to the pheromones of other genders and are bound by a strong mental and physical tie.
