Revenge. But a single word defines Kaito Ukei’s second chance at life. After being mercilessly betrayed and murdered by his so-called comrades, he goes back in time to the day he met the princess who ultimately double-crossed him. But killing her isn’t enough—he wants to revel in every second of her agony as he looks her in the eye and robs her of all she holds dear. Her debt is the first to be repaid, though it shall not be the last. And by the time he’s finished, he will bathe in the blood of every last traitor who dared to cross him…
Metalia ambushes Kaito just after he completes his latest feat of vengeance, forcing him through a portal back to present-day Japan. Stripped of his memories, Kaito comes to terms with his tragic new reality--a world where almost everyone he knows is dead and the police surveil him around the clock on suspicion of committing a heinous crime. Even this fragile status quo is disrupted when an assassin nearly succeeds in taking his life. But the brush with death restores Kaito of his memories and powers, giving him the perfect opportunity to take revenge on his assailant and chart a course back to his partners in crime...
