A brief description of the light novel Lord of Pets:
【Pets】【Masters】【Summons】【Contracts】【Evolution】【Mutation】
This is a world of monsters. Demonic beasts, demons, angels, giants, elves, undead, fairies, witches, beastfolk, insectoids… countless races, endless divisions, infinite mysteries. Human masters can make contracts with familiars. Hence, taming, grooming, ascension, evolution, battles… is their daily life!
