He is uncomfortable around Opera-senpai.

He is the "Watchdog of Babyls" and the top student. He fights by controlling Cerberus, a giant three-headed demonic hound. The Naberius clan are the "Noble Black Dogs who protect the Netherworld," a family of absolute loyalists.

He has been tasked with the role of "Watchdog protecting Babyls Demon School" since childhood.

He became childhood friends with Balam after happening to sit in the quietest seat where Balam was already sitting.

He dislikes people who are "noisy," "lack moderation," or "go at their own pace." He prefers quiet women and is reportedly weak to kindness.

He usually refers to himself as "Ore" and calls others "Kisama," but switches to "Omae" when speaking with close acquaintances or in informal settings.

He is excellent, serious, and prideful, but also a constant ball of grumpiness—gloomy yet strict. He calls everyone "trash" or "idiots." If a subordinate makes him angry, he resorts to physical force.

Because of his strong desire to touch and confirm the creatures he loves, his affection for living things (and sometimes the demons around him) manifests as physical contact.

His upper lip is scarred, leaving his left fang exposed. Out of consideration for others, he usually hides his mouth with a mask.

According to Opera, Kalego and Balam are their "underlings."

There is a group called the "Bancho Battler" that defeats delinquents and those who disrupt the order of the Demon School, consisting of Opera, Kalego, and Balam (Kalego and Balam were forced to join). Naturally, the leader is Opera.
