Synopsis
She Slays Monsters and Hearts Alike!
Bernstein, the daughter of a marquess but christened as a boy, attends an all-boys military academy. A knight of idol status, she must hide her gender from everyone—even her friends—to graduate. But she dreams of establishing an order of female knights in a kingdom where knights are exclusively male, hoping that one day she’ll be able to openly serve her nation with honor. When a monster appears, taking down knight after knight, Bernstein sets out to accomplish what no man has done before: vanquish a beast of legend and earn her place in history!
What will become of Bernstein as she prepares to fight this legendary monster that slays every knight that faces it? What will her friends and colleagues think when they discover that the strongest knight is actually a woman?!

Quite the pleasant read! It wraps up nicely. Thanks for sharing!
I’m guessing this is considered Gender Bender because she was christened as a boy?
