Red House

The Red House (い) is hinted to be the former home of Yugi Amane and Yugi Tsukasa, but due to the number of haunted occurrences and death befalling those who trespassed its grounds, it is currently unknown who owned the house previously.

It was nicknamed the Red House for its distinctive red roof, but despite the elements, the house still remains intact and overgrown by plants. It has tiled roofs and parts of the house separated into different quarters, as well as a second floor. In the front yard, a makeshift fence made out of beads is meant to keep out visitors.

When Nene and Kou visited the house after hearing a child's cries from inside, they were greeted with a collection of broken and discarded dolls. An unidentified ghost appeared behind Nene before vanishing, and one of the house's inhabitants is a young child with choppy, dark hair and dilated pupils, who is later revealed to be Yugi Tsukasa's younger self.

History
The house was home to several people and a family, as the child stated, and they still linger here. Due to some unknown phenomenon, those who live in the house must never go outside. It intercepted Kou's phone with an ominous warning the moment Nene tried opening the door with the child in her arms. When he appeared in the same room where the child was doodling, there were two doors across from each other: one that leads farther in and the other that leads outside of the house.

For those who are trapped inside the house, they are led down a labyrinth of paths pertaining to a wish or thought they want, whether it is materialistic or idealistic. It can grant any wish in exchange for an offering, given there's a door that leads to the outside. The current inhabitant of the house is presumably Tsukasa, but Kou's wishes were prevalently shown instead of his.

Locations
Although the house itself is dilapidated, it was seldom ever visited by people due to the number of suicide and accident-related incidents. There are a number of antique dolls strewn around, either with broken limbs and some missing eyes. In addition, there are unusual skeletons of small creatures left behind, presumably the corpses of lizards.
