When he moved to the Sanctuary along with all of his Valkyries, Sam was given an entire building near one of the entrances to make it easy for him to move when necessary.
With their ship being wrecked beyond repair he chose to relocate only the most essential of essentials there, which could be boiled down to three Eirs and the equipment needed to make use of his drones and the satellite he launched to space when they arrived.
The rooms had little in terms of furniture, but at the very least each one had a shower.
Sam took off his clothes, went in and started the shower, but after a couple of seconds he peeked outside and saw that Ichigo was still standing there, her face a brilliant shade of red as she stared at him with wide eyes.
"Aren't you coming?" He asked, holding back the urge to smile.
When they entered the room, Sam suddenly got the urge to see how the extremely shy Valkyrie would react if he suddenly began taking his clothes off.
