This was a bounty but I have actually seen this anime and forgot about it.

The thigh strap tends to get mirrored on the other leg and the corset doesn't always have the right shape at the bottom but it shows up often enough in my testing.

Please note that I have been switching between Illustrious and Pony a lot lately so add score tags as needed for your checkpoint. I messed that up on a few of the gens but they looked good enough lol.
