Saitama's Apartment

Saitama's apartment (サイタマのアパート, Saitama no apāto) is the primary residence of Saitama and Genos. The apartment is also a meeting spot for the Saitama Group.

Fubuki also makes this place as an office of the Blizzard Group without Saitama's acknowledgement.

Overview
Saitama initially lived by himself in the apartment building, before Genos moved in. The apartment resides in the middle of Z-City's ghost town, therefore Saitama is the only resident there. The apartment is small with a large living space, small kitchen and bathroom. Genos pays rent money to Saitama to live there.

During the Monster Association battle between S-Class heroes, Tatsumaki used her powers and destroyed the whole area, including the apartment. Saitama later got promoted to A-Class hero and moved to A-City headquarters.
