Rosti Naumann

Rosti serves as Will's roommate within the academy walls and stands out as an exceptionally talented magical tool creator in the field of magical engineering. He dedicates himself to developing supportive magical instruments designed to compensate for Will's inability to wield magic. Though his demeanor is warm and gentle, he carries an air of deep mystery, and his attachment to Will borders on an extraordinary level of devotion and protectiveness. Notably, the story implies that Rosti may in fact be an alter ego of Elfaria, operating from the shadows to quietly support Will throughout his adventures.
