The Demon King's dream is to raise a human cub, so he specially studied the "Human Cub Raising Manual".
The book says that human cubs look cute and need careful care, and breeders have the obligation to teach their cubs to walk and talk.
Until Lord Demon King met Claire who could run and speak: "Fake book, I will burn him."
Manual: "He's not a cub!"
Dispel (attack) × Claire (receive)
Intention: Get closer to each other and warm each other
