The mansion is indeed large, but it doesn't have many rooms. After all, it was initially meant for only Felix to live in, aside from the master bedroom, there are only two guest rooms.
Dedarose and Felix naturally don't have the privilege to sleep in a room. These two Holy Sanctuary Mages are at the bottom of the hierarchy in this mansion. Logically, they were supposed to serve Ash at night, but the Sword Maiden and others kindly relinquished such rights for Ash.
Although Sonia and the others aren't particularly concerned about ranks, if it's the idol Dedarose, Sonia would be happy to squeeze in. However, there's another issue — the sudden shutdown of Level Six of Hell from the Void Realm market has left demigod players displaced, but the Dream Stairs didn't shut down!
You demigods have Ash to support you, but we gain nothing from it and can only continue training steadfastly in the Void Realm.
