Omega Megaera

In a world where people have one of three sexes-alpha, beta, or omega-in addition to being male or female, alphas have pushed their way to the top. Omegas are oppressed, their status determined by whether or not they successfully bear alpha children. An omega named Saimon marries into the prolific Hanabusa family, a major conglomerate, but is unable to produce an heir for his alpha husband Seijuro, and is shunned as a “Megaera,” a creature that brings ill fortune. One day, Saimon is summoned by the family patriarch Zenjiro and ordered to locate the man's illegitimate son. Saimon finds the boy, Mamiya, who has been making a life for himself on the streets while hiding the fact that he's an omega. Desperate to regain his position as Seijuro's top spouse, Saimon proposes an audacious plan: pass Mamiya off as an alpha heir and try to gain the headship of the Hanabusa family.

Saimon's big plan is off to a perilous start when Mamiya goes into his first heat right after he's introduced to the Hanabusa family. And just when Saimon thinks they're in the clear, the Hanabusa family butler, Shiba, reveals that he knows of Mamiya's true nature-and he wants in on their plot. With Shiba's help, Saimon manipulates his way back into his sister's pharmaceutical company to make illegal heat suppressants for Mamiya. But will the pills be enough for Mamiya to survive in an elite high school full of alphas? And what's Shiba getting out of this arrangement…?

To take down Reiko in the student council election and secure himself as heir to the Hanabusa family, Mamiya joins forces with Reiko's peculiar former childhood friend turned rival, Lily. Despite Lily's adorable attire, the student council treasurer is willing to go to extreme lengths to see Reiko defeated, induding dredging up a tragic incident from the previous school year. But when lori, Mamiya's only friend in the Hanabusa household, ends up implicated in the scandal, how far will Mamiya be willing to compromise his own ethics to secure his future?

The student council election is finally upon Mamiya, Lily, and Reiko, and not only are their futures, but those of Saimon and the entire Hanabusa family, are riding on the outcome. The mood at school is in Lily's favor, but Reiko isn't giving up until the last vote is cast. In the wake of the election, Zenjuro announces who will inherit the headship, but his choice only further inflames the Hanabusas' internecine struggles. The alpha and omega members of the family aren't the only ones with agendas, either-Shiba is hiding a secret he's been nursing for decades, one that will rock Saimon's beliefs about his world. And there's still one more member of the family with a revelation in store…
