Additional thoughts
Picture the X-shaped reject mark (メ) trapped inside the cardboard box (凵). The crossing slash inside the container looks like a warning symbol—danger sealed within. The villain is literally boxed-up evil waiting to escape.

A cardboard box you reject bursts open, unleashing a wicked villain.
