The main residence of Sanae is Patricia's quite huge apartement on the surface of Pittsburgh, in one of the few cities with a bit more distance to the large industrial parts of Pittsburgh.
Planet Honshu
On Honshu's surface, unfar a large city is the Bessō Miyasu. A huge manor which was build around 460 A.S and since then is in the Miyasu's familys hands. Despite its age it still offers any luxury one could think about. It currently plays host for around 90 staff members as well as the small rest of Sanae's family.
Planet Los Angeles
Now that Iriel became part of the Miyasu family, her manor became part of the family's property too. Iriel's manor was once the home to a libertorian senator. His and Iriel's shared past, involving Iriel's actual family, leaded to his decease and Iriel taking over the manor. To Sanae's surprise her sister signed over the manor to Sanae. She owns it now but due to her position in Kusari, it rarely gets visited by her.
Freeport 1
While Sanae had been on Freeport 1, she decided to get a room permanently there. Right now it isn't in use by herself and she told the Zoners aboard that they could keep using it for visitors, even though she still practically owns it.
Planet Manhattan
A small apartement which was barely used in her times in Liberty. Nowadays rented to a Libertorian family.
Planet New Tokyo
A medium-sized apartment at the edge of the Kōkyo District. Serves as place for the night at very long days at the nearby office.
Planet Cambridge
To her own surprise, Sanae kept the keys for Sapphire's old safehouse on Cambridge's surface. Hoping that she will never need to really use it for the purpose it exists but one never knows. Though she has no idea if the safehouse even exists anymore, she decided to keep the key.
