WARNING: DARK AND MATURE CONTENT. Readers discretion advised.Serena Alaric wanted nothing more than a quiet life, far from the shadows of her family’s dark past. But when masked enforcers storm her home and drag her into the clutches of the Council of Vitae, she learns her blood is the key to a deadly legacy she never asked for.Lucian Draven is the cold and ruthless leader of a powerful mafia syndicate, cursed to endure unimaginable pain. The Council claims Serena is his only salvation. Yet beneath the Council’s polished facade lies a web of lies, experiments, and betrayal that runs far deeper than either of them imagined.Forced into an uneasy alliance and given a time limit to produce an heir, Serena and Lucian must navigate a treacherous world of power and manipulation, where trust is a rare commodity. As they uncover the truth about the Council’s sinister plans, their hatred begins to give way to something unexpected—a bond forged in fire and blood.But with enemies closing in from all sides and time running out, Serena and Lucian must decide: will they fight their fates, or embrace the dangerous connection that could either save them, or destroy them both?

15 years ago the world discovered magic as well as mythical beings (basically beings from various legends) in another dimension. Humankind learned to summon these dangerous mythical beings and use their power to great effect. Seven countries formed contracts with these “mythical beings” and gained their allegiance as a result. The mythical beings will choose their summoners on their 14th birthday and give them a stigma. Schools have been set up to train summoners and magical swordsman (basically bodyguards that give the summoners time to cast their spell) as a result.

15 years later after the finding of magic Kazuki Hayashizaki is chosen as a summoner and given a stigma to indicate that. This is surprising since males aren’t chosen as summoners due to their low amount of mana compared to females. As the first male to be a summoner Kazuki is under a lot of scrutiny by almost everyone.

To complicate matters his sister (who’s a magical swordsman) is against him going into summoner school to train there as a summoner. Because summoners and magical swordsman have a cat mouse thing going on where summoners look down on magical swordsman as inferior so his sister naturally is against him going there. She’ll stop him even if it means going to war.

Kazuki however is determined to thrive in summoner school and has already determined to give it his all. Even if he’s the lowest ranked student (ranked E) and his fellow students intend to demean him he’ll prove himself as the strongest summoner.
