Ruche from Trillion: God of Destruction. Swimsuit isn't that great, tagging for it is off and AI is shit at asymmetrical stuff but it kinda works. You can use the tattoo where applicable though. Great Overlord Ruche doesn't have any, not like the game explains how the Great Overlord crest works anyways ^ ^;

small breasts = for her usual look

medium breasts or large breasts for great overlord timeskip look
