This is Yiz's mansion, with a huge structure and the house of a super giant dog named Yiz. This place is extremely huge and can satisfy Yiz's daily life here. But at the same time, tiny commercial streets and residential areas are everywhere in the cracks of the ground, bricks, and beams. This huge house is a huge city for normal people who live in the cracks and interact closely with Yiz from time to time. No one gets hurt. Dwellers enjoy the sight of Yiz's huge body parts.
