After being reborn in another world, Irene thought she'd been handed the protagonist's script: transmigration, magic, swords, and knights, the whole standard package.
She studied under a master, trained relentlessly, and by the age of twenty had become the youngest Grand Knight Commander in the Human Empire.
She thought she could keep enjoying smooth sailing and become one of the most powerful people in the world.
But before long, a beautiful silver-haired girl dressed in black Lolita clothes dealt her a crushing blow. With just one casual strike, Irene was left on the brink of death.
Kneeling on one knee, Irene stared at the silver-haired girl with blood-red eyes. She was none other than the Human Empire's most powerful enemy, the Empress of the Bloodmoon Empire.
"Lilyas..."
"You certainly have some nerve, Your Excellency. You dared to fight me alone just to cover your teammates' escape."
"Heh. I'm not far from death anyway. Kill me or do whatever you want."
"Oh? Is that what you say..."
The other girl gave her a wicked grin.
When she woke again, Irene found that her hair had turned white. And her teeth... why did they feel so sharp?
In the mirror was a silver-haired girl with blood-red eyes, who looked remarkably like Lilyas.
How had she become a vampire?!
"Natia Bloodmoon, I look forward to getting along with you from now on, my daughter."
"???"
Wait, who's your daughter?!
And why had the Human Empire's mighty Grand Knight Commander woken up as a vampire princess?!
