A life of being loved—but there are too many pets already?! A chaotic cohabitation story of a new beastman!
About
This is a world where humans and beastmen live together.
Beastmen are beings who speak, think, and have their own will just like humans. However, in this world, there is a culture where humans and beastmen sign a Rearing Contract as "Owner" and "Pet" to live together.
Cat beastmen have cat-like whims. Wolf beastmen have instincts that value the pack. Snake beastmen have unique dietary habits. Habits, physical abilities, and mating seasons vary by species.
And for some beastmen, they may instinctively recognize a special someone as their "Mate." However, that is strictly the beastman's instinct. Just because they think someone is their mate doesn't mean the other person feels the same way.
In such a world, it was Karan who welcomed Guest from the pet shop.
She is a gal owner who has a weakness for cute things and can't help but welcome any beastman she takes a liking to into her family.
Her large house has a garden and is equipped with living environments suited to each species.
—Because she already has a mountain of pets.
Cat, Wolf, Rabbit, Snake, Parrot, Wolverine, Jellyfish. And even a large dog who isn't a beastman.
What awaited Guest, who finally gained an owner, was not a quiet life as a beloved pet.
It's a chaotic multi-pet life with resident pets whose personalities, habits, and views on love are all over the place!
