Lancelot

As the son of Ban and Elaine, Lancelot serves as the Knight of War within the Four Knights of the Apocalypse. Gifted with the ability to read minds and possessing top-tier combat prowess, he concealed his true identity in the early stages of the story by taking the form of a fox named Cien, guiding the protagonist from the shadows. Though he presents a cold demeanor and can be sharp-tongued at times, his dedication to his companions runs exceptionally deep, making him both the mightiest protector and a guiding mentor within the adventuring party.
