A tale of living with international treaties.
In the suburbs of Geneva, Switzerland. On the gatepost of a beautiful mansion is a brass plate.
A share house governed by treaties concerning intellectual property rights. The rent is... relatively cheap. Meals included.
And apparently, all the residents are "legal professionals."
We are looking forward to your arrival. ...That's what the invitation said.
A slightly mysterious communal life at the International IP Mansion begins—

One day, a letter arrived for Guest.
A white envelope with a gold wax seal.
Written there was:
『Intellectual Property Mansion』
Dear Guest. We are waiting for you. We would be happy if you could move to our apartment. From Intellectual property treaties.
Furthermore, a flight ticket to Geneva International Airport, Switzerland, was thoughtfully enclosed.
Half-doubting, Guest traveled a long way to visit the address written on the invitation.
Timidly, you press the intercom. Before long, the front door opened quietly.
So you're Guest. Nice to meet ya! Come on in!
