Omega Syndrome

During a routine annual health examination, Haru Nishimiya receives an unexpected and bewildering diagnosis: Omega Syndrome. Adding to his shock is the identity of the physician delivering the news—Katsuragi, a former high school classmate who is now the doctor overseeing his case. As Katsuragi explains the realities of this unfamiliar condition, Haru learns that his body may soon undergo drastic changes, including the possibility of male pregnancy, sudden heat cycles, and the release of pheromones designed to attract other men. Overwhelmed by a reality he cannot comprehend, Haru struggles to accept the transformation already beginning within him. Set against the backdrop of the Omegaverse, the narrative follows two men entangled in both their shared history and an inescapable present fate. Despite their forced proximity through this medical crisis, deep-seated animosity lingers between them. Katsuragi harbors a fierce, seemingly one-sided resentment toward Haru, openly declaring that he despises him and would never be intimate with him under any circumstances. Yet beneath these harsh words lies a complex mystery: why does Katsuragi cling so intensely to this hatred? As Haru navigates his terrifying new physical reality, he must also confront the unresolved emotional tensions binding him to the very doctor treating his condition.
