Hero, You Can't Marry Your Archrival

Reincarnation should have been the start of a wonderful life, until Sarafi opened her eyes and discovered that not only had her gender changed, she hadn't even kept her species.

As a member of the "Ring Clan," an enemy of humanity, Sarafi was born just as the regime changed. One of the heirs to the former ruler, the "Arcane Emperor," she was appointed (exiled) to serve as a border lord on the front line against humanity before she'd even had a sip of milk.

But Sarafi had a good attitude. No troops? No problem! No money? She'd make do! As long as the humans didn't invade, she was perfectly happy to slack off while staring at those headache-inducing financial reports.

Then war broke out.

Looking at the sea of human soldiers beneath the city walls, then at the ledger full of red ink in her hands, Sarafi fell into deep thought.

But three seconds later, she quickly made a decision that went against everything her ancestors stood for: surrender.

She tied her own hands together and slowly walked up to the human army. "I surrender. Make it quick, please."

The hero leading the army, the champion, stared at this "enemy of humanity" who had offered herself up for execution and remained silent for a long while.

Then, as the entire army watched in stunned silence, the strongest human dropped to one knee:

"I want to ask for your hand in marriage. Will you marry me?"

Sarafi: ???

Wait, did someone hand me the wrong script?

Hero, we're sworn enemies. Sworn enemies can't get married!
