Kalego Naberius

Professor Naberius Kalego stands as one of the most formidable figures within Babyls Demon School, commanding respect and a healthy dose of fear from students and fellow teachers alike. As the homeroom teacher of the notorious Misfit Class, he enforces impossibly high standards while quietly investing in every student's growth. Despite holding the impressive Rank 8 designation, fate took a humorous turn when the human boy Iruma accidentally summoned him as a familiar — transforming this fearsome educator into an unexpectedly fluffy and adorable creature. This striking contrast between his stern demeanor and cute familiar form has made him one of the most beloved mentor figures in Welcome to Demon School! Iruma-kun.
