Derisive, snappy, and short-tempered, he strongly dislikes demons who are boisterous, brash, and inconsiderate of others, believing them to be troublemakers. As such, he is generally pessimistic when dealing with his students. Due to how the familiar summoning spell works with humans, Kalego unwillingly becomes Iruma Suzuki's familiar for a year. When summoned, Kalego appears as a fluffy white creature resembling a small crow, complete with black bat-like wings, black horns, and his distinctive front hair curl.
