"Your case is not fused with the flooring," Ryuuko stated, eyeing the vase's ultimate defence carefully. Having considered how their thief had bypassed all the other defences, here presented one avenue in that took even less work than moving the wall away: at least the wall was a single continuous structure, "Which leads me to assume that the thief could have removed the floor and worked their way beneath the vase. Or they could have displaced merely a part of their own body to be able to access and move the vase. Even without cancelling the defences on this case, they have displayed a potential ability to move the mansion's walls out of the way and I doubt that a clear container would be much impediment."
