Everyone likes to rave about the men in the harem (because they deserve it tbh) but one of the biggest pulls of the series (if not THE pull) for me is Yeldriya herself. Thrust into the body of a cruel "real" villain (who is also influential), knowing absolutely nothing about this game, faced with a heroine that is determined to "clear" it, and having to protect herself under these circumstances is way too much to handle normally. But Yeldriya tries to pull through, getting teeny bits of information at a time, trying to keep in-line with the villainess's character, and save her skin.
She tries to act responsible for her current body's past behavior as much as she can and help those who were affected, but doesn't completely ease up on her villainess act, so she's still acting like an authoritative and slightly cruel person. Moments like the latest chapter only help add to her character. Lots of character development for her, and I'm excited to see what's next.
