Зеотикус Гремори

Lord Gremori, the current head of the Gremori family, whose real name is Zeoticus Gremori, is the husband of Venelana and the father of Rias and Sazeris, as well as the grandfather of Millicas. He gets along well with the parents of Issei Hyodo. When the girls from the occult club started living with Issei, Rias asked her father to renovate the Hyodo house. The new house that Lord Gremori built in one night has three floors, two basements, an underground pool, and a large kitchen. However, it turned out that Lord Gremori wanted to build an even larger house and had planned for it to have many maids working there, but Rias talked him out of it.
