Hyoudou Residence

The house of Issei Hyoudou and his parents, which later became the house for the girls of the Occult Research Club, the female members of the Vali Team, and the Dragon God and her spawn. Originally a two-story terrace house, it was renovated in Volume 5 into a six-story building with three large basement floors. Following the house's renovation, it also has more than twice the land area after buying the lands of their neighbors.
