I Was REBORN As The Villainess's Pet HOUND, But I'm Secretly an SSS-Rank Monster!

He died protecting a village nobody asked him to protect. Now the most feared creature in existence is six weeks old, fits in a basket, and belongs to a girl everyone calls a villainess. Wei Lin thinks she bought a pet. She has no idea what's sleeping on that pink pillow. Someone is sending people to her garden at night. Her engagement is being destroyed from the inside. Her father is being manipulated by the second most powerful man in the empire. And every piece of it has been moving for eight months without her seeing a single hand. She's alone. Except she's not. Because whatever Kei actually is — gods avoided eye contact with it. Armies ran from its name. And right now it's watching her back. She just doesn't know it yet.
