Harry Potter and the Knight King of Hogwarts

Luna Pendragon, a legendary Hogwarts graduate, returns to her alma mater as the youngest professor in history, wielding EX-rank magical power and an ancient legacy of Runes. She takes charge of the perilous Defense Against the Dark Arts post. Her mysterious assistant, Artoria, is elegant and powerful, and her true identity is none other than the King of the Knights of Britain, who crossed through time and space.

As Voldemort's shadow quietly rises again in the Wizarding World, undercurrents stir beneath Hogwarts' peaceful surface. Luna's revolutionary teaching methods ruffle the feathers of pure-blood nobles, while Artoria's arrival awakens the fated echoes in the bloodlines of the Round Table's descendants, dating back a thousand years. Magical duels in the classroom and secrets hidden deep within the castle all point to an even older mystery.

On a board where magic, courage, and fate intertwine, a professor wielding the power of the stars stands shoulder to shoulder with a king who commands the Holy Sword. How will they illuminate the darkness and protect this thousand-year-old castle? A legend transcending magic and time is about to begin.
