Ori no Naka de Bokura wa Ban'u

The "Emperor" surpasses even the Alphas and stands at the top of all genders. One of them is Mashiro Mikoto, an Omega who transfers to an all-boys boarding school run by Kurokawa Aki. Mikoto had been hiding his gender and hoping to live a peaceful school life, but Aki noticed him and discovered that he was an Omega. "Cry, I'm the absolute leader here." In exchange for not revealing anything, Aki lets him embrace him as he pleases. Although Aki wants to refuse, his instincts are stimulated by Emperor's overwhelming pheromones, which he has never felt before, and his body begins to crave Aki..!? The dramatic omegaverse woven by the solitary "Emperor" and the lonely "Omega" begins.
