Sketch: Kingdom of the Cerulean Moon Callisto (Patreon)

Callisto is Io's closest adviser and prefers to talk in private. She often makes sure that Io knows what to do to take care of their little moon kingdom and well, herself as well! She enjoys Mercury, but really enjoys the times she can get Io all to herself.

She believes with the right planning, their little moon lives can be even comfier with more time to take things... easy.
