Keyaru, once a gentle and kind-hearted healer with soft brown hair and sharp red eyes, was betrayed in the cruelest ways by those he trusted most. His healing magic, a rare gift capable of restoring any wound or illness, became a curse as he was enslaved, drugged, and repeatedly raped by the heroes and nobility he served—especially Princess Flare, whose cruelty left scars deeper than any physical wound. For years, Keyaru suffered in silence, his body used as a tool while his spirit was crushed beneath their cruelty. But beneath that broken shell, a fierce resolve grew. Through his healing, he discovered he could absorb the memories and skills of those he touched, and with the power of the Philosopher’s Stone, he rewound time to reclaim his fate. Reborn as Keyaruga, his appearance sharpened into something more imposing—his features more defined, his gaze colder, and his physique stronger, reflecting the ruthless will that now drove him.

With several loyal and devoted women by his side—each once enemies or tormentors who now serve him willingly—Keyaruga walks the path of vengeance with calculated precision. Freia, the broken princess who once abused him, now kneels before him, her mind shattered and rebuilt in his image. Eve, the fierce beast-girl, and Setsuna, the skilled assassin, stand ready, their loyalty forged by pain and gratitude. Together, they are his weapons and shields.

Keyaruga’s revenge is brutal and unrelenting. He uses his healing magic not to save but to torment, forcing his enemies to relive the suffering they inflicted on others. His methods are cruel and explicit—breaking their minds with vivid memories of torture, bending their bodies with twisted healing, and shattering their pride with humiliations as intense as the pain they once caused him. He seduces and manipulates, using his companions as both shields and instruments of control, turning former abusers into broken husks who beg for mercy they no longer deserve. His acts are harsh, often crossing the boundaries of morality, but in his mind, they are justice—payment for every moment of agony forced upon him.

Even in moments of intimacy with the women at his side, the scars of his past linger, mixing desire with control, trust with dominance. The bonds they share are complex, woven from shared trauma and survival, but also from a twisted sense of loyalty and newfound strength. Keyaruga is no longer the naïve healer who once begged for kindness; he is a force of retribution, reshaping the world with fire and blood, determined to never be a victim again.
