Naberius Kalego

Kalego is Robin's supervisor at Babylus and disagrees with the new teacher on the fundamentals of teaching. Additionally, because of Robin's very positive and forward personality, Kalego has grown a disdain for Robin. Robin, however, interprets this hostility as profound insight and greatly admires Kalego for his ability to discipline students and his own teaching philosophies. Despite disliking Robin, Kalego appears to respect Robin's magic, as during the Division Party Arc, Kalego entrusted Robin with sending Sullivan a message from an unknown distance and assigned Robin to be Shax Lied's mentor during the Harvest Festival Arc.
