Red Knight: Servant of Shield Hero

A boy who was supposed to have a happy life disappeared from Earth. Stuck in a void, he was reborn as Mordred Pendragon, but this isn't the fate universe he used to know, and why is he a "girl" now?! With the death of King Arthur and the Black Dragon wreaking havoc on the world, she raised her sword and fights the Black Dragon. She ultimately defeated the dragon at the price of her second life. But now the third chance has been bestowed on Mordred. Summoned by Naofumi Iwatani, Mordred swore to be loyal to him as his Red Knight. This time, she will create another legend, but not alone.  - (Rising of The Shield Hero fanfic) Missing Genre: Gender Bender (Male to Female) Slow updates warning.
