Iinari!! Kyuuketsuhime

Iinari!! Kyuuketsuhime is a manga that revolves around the life of a vampire named Lucrezia, who originates from outside of Japan. Her primary objective is to acquire the "Supreme Blood," which is believed to be the pinnacle of vampire power. However, this elusive blood source resides within the body of a diligent young woman who is completely absorbed in managing her finances to support her family. When Lucrezia encounters her target, a series of unexpected events unfold. During a fierce confrontation, Lucrezia is inadvertently weakened by a charm, resulting in a significant loss of her powers and a remarkable transformation that makes her appear younger. In an effort to recover her lost abilities and claim the Supreme Blood, Lucrezia is compelled to adopt a new approach – working to earn the very blood that she initially sought to acquire by force. As a vampire with limited worldly knowledge and unaccustomed to interacting with others, Lucrezia must navigate a complex and unfamiliar environment, all while facing the challenge of earning the trust and respect of those around her.
