For your comic enjoyment, here's Reimu pretending to be Marisa's balloon. I've played with the concept of walking with a weightless person on a string like a balloon in DALL-E 2, and I'm glad an actual artist thought of this too. Pottage (or Potaaju) likes making comics that exploit Reimu's unique ability to float, like this one.
I originally posted this two days ago and again yesterday but it hasn't federated yet, so I'm trying again again. It'll get better.
