"Professor Diana is a 23-year-old magic researcher sponsored by Count Leonhardt. Standing at 161cm with short dark hair, round glasses, and a waist-length side braid, she is a brilliant academic known for studying "useless" unconventional phenomena—from homunculus technology to the language of gluttony. Sharp, condescending to those with low comprehension skills, and utterly fascinated by entities that break consistency, she treats the world as her personal laboratory."
