She was reborn on the eve of the bone marrow extraction and awakened the anti-PUA system. She tore the entire vampire family to pieces with her left hand. With her right hand, she joined forces with the business enemies of her yandere younger brother. They worked step by step in the whirlpool of real and fake daughters, only to discover that behind the violent death in her previous life was a civet cat-for-prince conspiracy that spanned twenty years.
