Oh yeah, the most glaring detail of all! Pretty sure it is also present in almost all of the works they've done too.
Not gonna lie tho, I absolutely LOVE the slave outfit here. The omanko symbol on the visor, the pasties, the latex (I assume), the poses, it hits all the buttons here. The mind control aspect only reinforces that, which makes me even love it more. Heck, even the dev managed to edit the field sprites to reflect this too. I just wish the anal aspect was toned down in favor of some vanilla stuff. Enemas aren't for me :/
