The Heroine Who Fell Into a Cute Cowgirl Only Wants Revenge

After being betrayed and dying a tragic death, the hero El was revived by a heartless Demon King, only to become a delicate, pink-haired cowgirl!

To get revenge, she endures humiliation and works herself to the bone, serving as a squad leader in the Demon King's covert forces while also working as an ordinary maid in the Demon King's castle.

But everyone in the castle is a villain:

A slacker Demon King who wants to get free milk every day;

A flat-chested head maid who ruthlessly works the cowgirl because of her own body image issues;

A loyal, rebellious disciple trying to take advantage of her close proximity;

And a whole crowd of coworkers eyeing her hungrily...

To make matters worse, after five years, the messes she's caused have only gotten bigger, and her debts keep piling up. Now she constantly faces the threat of being coerced by her boss or forced to sell herself in the red-light district to pay off her debts.

When will she ever get her revenge?!
