Summer Helena basically rides a D-Bike or whatever the thing is called in her Noble Phantasm.
Oh. I had to look up references on what that looked like (post #2852690).
In that case, trait connection is still invalid, because it shows the wrong Yu-Gi-Oh character; Yusei's D-Wheel is more of a motorcycle. It would be valid if it showed Jack Atlas instead; his D-Wheel is also a monowheel (proof: post #726365). Another valid example: post #2816857
