I’ve Transmigrated as the Supreme Villainess... But I Have No Idea WTF I’m Supposed to Do!

Parody Visual Novel of Soul Union. The last thing I remember was falling asleep sometime in the middle of the epilogue. And then waking up… All around me is the landscape of a low effort paint and sketch filter. Oh. I am savvy enough with anime related fandoms. When I run out of visual novels to play, I read light novels. I must have been isekai’ed into the game that I had just wasted my entire night reading. At least I didn’t die getting hit by Truck-kun? By the looks of this huge rack and impossibly long purple hair, I am in the role of supreme villainess, Noctisse.
