I tried getting Ayame into a maid's outfit but it wouldn't fly, sadly she had good reasoning as well. If a noble's butler goes on a buying spree it's pretty normal to have guards protecting me and the wares I acquire, a position she was more than happy to fulfill. Naturally, we would be wearing our masks.
Why all the secrecy? We will be using the storage ring to our heart's content, so it's best to pretend to be of a noble background, who would be able to afford such an artifact. Doing so would also make the common riffraff steer clear of us, ideally even the guards as well.
As for Luke's party's corpses that were occupying my spatial storage, they've been emptied out during the past week in a random ditch, though I kept his skull for collection purposes.
Once we were ready, the three of us teleported to the shady alley where we killed Ian, Grunt, and his two slaves, and thankfully no one welcomed our exit from the gate.
