Cube House

Cube House (キューブハウス Kyūbuhausu) is the Stand of Penelope de la Rosa, who unknowingly wields it. It evolves into Arrow Cross House, the main body of Reimi Sugimoto.

Appearance
Cube House appears as a white Tesseract-like structure because of its four-dimensional interior. Its walls have doors all over them, leading to different rooms. It has no windows or doors from the outside, nor any known entrance.

History
Back in 2004, the Cube House had just suddenly moved to Morioh from Nishi Akatsuki. None of the people from the town had known who it belonged to, or where it came from.

Structure
Its interior is built like a fourth-dimensional Tesseract. With eight rooms joined together on every side. The doors inside of the house leads you to a different room each time. Joji explains that the House defies all logic and the laws of physics because of its bizarre rules. He lists them below in order: "1. Parallel movements remain on the floor.

2. Doors on the floor always connect to the ceiling.

3. The side doors to Rohan's study do not connect to the next rooms of the Cube House, but to the halls of the Arrow House."

The Secret Universe
Because the House has seven cubes, it forms an eight cube which surrounds all of them. Allowing it to create its single universe of its own, meaning the walls of the House are the borders of that universe. Meaning if you attack the House or damage it whatsoever, it will never reach the inside of its interior.

Joji wonders how Fukashigi and Rohan avoided exploding from Kira's Killer Queen after being placed under the Arrow Cross House. He learns that under the Arrow Cross House, was the Cube House. And reveals that in there, was a zone where everything was set to zero.

The House is only designed for one person only. Reimi warns Joji that if one or more people are in the House, it will cause 'contradictions', making the rooms rotate in order to make space for its inhabitants. In order to solve the contradictions, the Cube House will pull one of the persons and will send them into a parallel universe, trapped there forever with no escape.
