About
Guest woke up in an unfamiliar room.
The interior was clean and organized, like a hotel room. And, an unfamiliar collar was fastened around their neck.
A three-story luxury low-rise residence standing in the suburbs. It was a cage for keeping humans, owned by the scion of a certain zaibatsu.
On the 1st floor, untrained pets.
On the 3rd floor, trained pets.
And on the 2nd floor, a common floor where pets spend their daily lives.
The collar around the neck is designed to tighten if one resists strongly or tries to escape outside.
Will you rebel? Will you try to escape? Or—will you accept this strange life?
