Eira Kingston, a feared assassin, never imagined that death would lead her to transmigrate into the body of Ephyra Allen, the disgraced first daughter of the once-powerful Allen family. But what shocked her even more was the soft mechanical voice in her mind, addressing her as “master” and informing her that her soul had returned to its original body.Eira dismissed the strange voice, thinking she was having a post-death hallucination. But waking up in a hospital, with memories that weren’t hers flooding back, she was forced to confront the truth.Ephyra’s life had been nothing short of a nightmare. Despite being the legitimate daughter, she was labeled a bastard, shunned by all, and overshadowed by her scheming stepsister, who had stolen the love of her father and her betrothed. To make matters worse, the wealth and status the Allen family enjoyed were all thanks to Ephyra’s late mother, and the only reason she hadn’t been discarded entirely was due to her mother’s inheritance, locked away until she turned eighteen.But Eira wasn’t one to be defeated by circumstances. If she was going to live Ephyra’s life, she would do so on her own terms. She would destroy those who had caused Ephyra pain, claim the inheritance that was rightfully hers, and find out who was behind her own death. Because if there was one thing Eira knew how to do well, it was to survive—and make her enemies pay.However, being a high-schooler with nothing to her name wasn’t enough. As Ephyra, she’s powerless, but as an assassin, she’s lethal. Still, even that wasn't enough until she became the contracted wife of Lyle Aelion—a powerful, enigmatic figure in the business world with a secret illness. And it turns out, the only thing that can relieve him is her scent.

In the Central 46 Compound, the Captain-Commander of the Gotei 13 and the notorious scourge of the Female Shinigami Association, Masatsuki Aozaki, stood before the Sages and Judges.“You have improper relationships with numerous members, Seated Officers, and Captains of the Seireitei?”“As Captain-Commander, maintaining close relationships with them helps facilitate my work.”“...”The Judge narrowed his eyes. “Then how do you explain modifying the female Shinigami's Shihakushō into miniskirts?”“To transform the Seireitei into a perfect paradise.”“Tsk tsk… A paradise for all Shinigami? That’s not entirely unreasonable…”“No, a personal paradise.”“A private—wait! Captain-Commander Masatsuki, that kind of thinking is clearly wrong!”“Do you want to die?”“...”“Forget it, Captain-Commander Masatsuki. We’ll set this matter aside for now. Let’s discuss some of the outrageous statements you’ve made in the past. Those were jokes, right?”“No, I was completely serious.”Masatsuki calmly ran his hand along the hilt of his Zanpakutō and spoke with conviction. “I have a great relationship with my subordinates, I get along well with Hueco Mundo, and I’m even friends with all of your wives and girlfriends. But rest assured, I’m a good Shinigami. You can safely leave the world in my hands!”Genryūsai Shigekuni Yamamoto: That damn brat! Shunsui, Jūshirō, don’t stop me—I need to teach him a lesson!Thus begins the tale of the most incorrigible Shinigami!
