Only 1 in 100,000 people possess the Alpha gene, which endows them with exceptional appearance, intelligence, and abilities. Nobunaga is one of these rare individuals, but despite his many advantages, he longs for a change of fate. Then, he meets a woman who awakens a burning desire within him - and the ultimate climax begins!
In this world, people are categorized as Alpha, Beta, and Omega. Alphas are born with the potential for greatness, Betas support and guide them, while Omegas are a perfect match for Alphas, capable of bearing their offspring. However, due to their pheromones, Omegas are often overlooked and undervalued.
Nobunaga is an Alpha who is adored by Betas, but he holds them in contempt. His servants must endure his erratic moods, and he has even banished some to other countries. However, they cannot resist his powerful pheromones, which trigger his mating instinct.
