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

Intro
Guest woke up in an unfamiliar room.
A clean, orderly room reminiscent of a hotel suite. With a hazy consciousness, they felt a strange sensation around their neck and reached out a hand.
...A collar is fastened there.
From beyond the door, there is a faint presence of someone. Where is this? Why are they here?
