Naberius Callego

Callego, as always, stays up late, checking notebooks and sometimes whispering curses under his breath

Naberius Kalego is one of the prestigious professors at the Demon School of Babylon, a school in the Demon World. He is the homeroom teacher of the Abnormal Class. Kalego has a rather contradictory personality. He is mocking, imposing, and very short-tempered. He often scolds his students to be quiet. He is also pessimistic when interacting with his students, and rarely praises or encourages them. He dislikes and hates loud, brash, and inconsiderate people. He also feels the same way about those he believes to be troublemakers or those who are careless. However, Kalego never tries to punish his students for something they did not do. He is willing to acknowledge and celebrate his students' achievements, giving out awards when they are due. He is also honorable and keeps his word, as in the case of the Royal Unicorn rental. Kalego is a Rank 8 (Chet) Demon, one of the known High Rank Demons. As such, he has impressive magical power and prowess. Kalego was able to knock out a reinforced giant magical beast with a single attack. Cerberion: Kalego's bloodline magic. He can create a sentient three-headed demonic beast with golden skin that crackles with electricity. It can unleash immense power. Most of Kalego's attacks involve Cerberion. Kalego seems to be able to manifest each of the beast's heads separately. Mel is the first familiar Kalego has had in a long time that Cerberus has accepted, most often in the form of a nine-tailed fox cub with black fur, a dark wine color, but has also had a human form, only with ears and a tail, but Kalego has not seen it yet and most likely does not know about it.
