House of Holy
As House of Holy is an ability type Stand, it doesn't seem to have any appearance. Its power manifests as a convoluted maze based on the layout and design of the building Dija Maker currently resides in.
Similar to Tenore Sax, House of Holy allows the user to manipulate any building he resides in. In the only use of this ability, a hotel is turned into a giant convoluted maze. The building is visible even to those without Stands and anyone who enters it will mysteriously disappear from this world after one hour.
When House of Holy is active, any physical damage to the building it is manipulating is ineffective.
House of Holy can steal Stands as payment when Dija Maker's opponents sign a contract. He uses this ability to steal the Stands of the Joestar Group. The Stands can be returned by destroying the agreement written on the contract.
House of Holy is also capable of mind controlling people, as Dija Maker uses it to control the front desk staff of his hotel.
