I Possessed a Body and Became an Urban Legend

Waking up inside a coffin on the day of her own funeral, she assumes she has transmigrated into a standard romance fantasy novel. Judging by her terrified maids and cold family, she figures she must be the classic doomed villainess and uses a mysterious magic circle to summon a powerful beast for protection. Instead of a fierce dragon, she summons a bizarre, three-eyed, leopard-spotted orange cat! While she happily embraces her cute new pet and cheerfully tries to survive her assumed "romance novel" plot, she is completely oblivious to the horrifying reality. To everyone else, this isn't a romance at all she is a terrifying monster wearing a dead noblewoman's skin, and her cheerful antics are plunging everyone around her into a living, breathing horror story!
