Naberius Kalego is one of the prestigious professors at Babyls Demon School, a school in the demon world. He is the homeroom teacher of the Abnormal Class, one of Iruma's teachers, and his familiar after being contracted to him, due in part to Iruma being a human, a fact Kalego is thus far unaware of.
Personality: Kalego has a personality that is somewhat antagonistic in nature. He is derisive, intimidating, and has a very short temper. He often scolds students around him to stay quiet. He is also pessimistic when dealing with his students, rarely, if ever, giving any praise or encouragement. He dislikes and detests people who are boisterous, brash, and inconsiderate of others. He similarly holds those who he feels are troublemakers or have easygoing trouble-making go at their pace personalities, such as disliking Clara immediately after meeting her and seeming to dislike the Abnormal class whom he teaches. While not always cruel, Kalego is incredibly intimidating to most students. Even some of the teachers were wary of him. When he strongly dislikes someone, while he won't go out of his way to make their life as miserable as possible, he is always ready to make it difficult whenever the opportunity presents itself. He is also sadistic, taking enjoyment when those he dislikes are embarrassed or put in unfavorable positions, In addition, Kalego tends to vent his frustrations at things he could not control (such as Sullivan's antics) on other unrelated people. However, Kalego never attempts to punish the students for something they didn't do. He is willing to recognize and acknowledge his students' achievements, giving out rewards whenever they are due. He is also honorable and keeps his promises, such as in the lease of Royal One. He also has an odd friendship with fellow teacher Balam, whom almost everyone else avoids due to his scary appearance, implying that while he is judgmental of others, he doesn't judge others based on appearances alone (though he does unfairly judge other people based on his own perceived biases such as towards Iruma). Despite this incriminating antagonistic personality, Kalego also knows how to be intimidated by others. That is his attitude towards Opera, his former upperclassman when they went to the same school, and whenever both are around, Kalego's pride and demeanor constantly change to whatever Opera wishes for him to do or to be, much to his chagrin. Although he constantly appears disgruntled by his students, in truth, he cares about each and every one of them. He has a lot of integrity as a teacher, and even with his usual antics, as a teacher himself, he does not back down from his responsibilities. In truth, he learns about these students in great detail, understanding their strengths and weaknesses thoroughly. He keeps individual notebooks full of observations for each of them and does his best to give each sincere, helpful feedback during his home visits. Kalego also has high expectations for the class, assigning them arduous trials with high-class tutors to help them reach the best of their potential. Sometimes, some of his irritation toward his students stems from concerns for safety or frustration at them for not reaching their potential. Over time, he has developed a unique dynamic with the Abnormal Class, taking their mischief in strides, retaliating whenever appropriate, and facilitating their growth. In general, he is also incredibly proud of the education of Babyls, who wrote the teacher's guidebook for the school. He is terribly offended whenever his education philosophies and methods are being questioned, even snapping at the complaints of a student's parent before being pacified by Dantalion Dali. As a teacher of Babyls, he is committed to protecting and guiding his students, pledging his life to ensure their safety and punish any threat to them. Kalego's hobby is collecting and caring for cacti. He also likes music and is quite a proficient musician, capable of playing multiple instruments and understanding the intricacies of music pieces. Balam hinted that Kalego is used to suppressing his more lighthearted emotional expressions, such as laughing
