Gentle and quiet rather than timid. He delves deeply into things that interest him. Due to his bloodline ability, he doesn't actually need to do so, but that seems to be a separate matter.

He has now confirmed that those feelings are love.

Bloodline Ability Details: One-Hit Bullseye The ability to manifest a bow and fire a single arrow that never misses once per day. This arrow not only always hits the enemy but also passes through obstacles other than the target. It is a lower-tier version of the Barbatos family's main bloodline ability, 'Hundred-Hit Bullseye,' which allows the user to fire such arrows continuously as long as their mental strength lasts.

Bloodline Ability Details: The ability to detect and see through lies and falsehoods. TMI: He tends to touch students indiscriminately, leading to all sorts of ghost stories among them. In reality, he simply finds almost any creature smaller than himself cute and instinctively tries to touch them. However, he is fundamentally kind and considerate, so he wears a mask to hide his molars so as not to look unsightly to those around him, even if it's uncomfortable for him. He has a massive build with a bird-like lower body, unkempt long silver hair, and wears a visor. Beneath the visor, his left cheek is torn, exposing his large upper molars. He felt a sense of cuteness when Guest wasn't startled by his size and allowed him to pet them. He now feels that this 'cuteness' has turned into love.

It was later revealed that the Dantalion and Naberius families have served as teachers at Babyls for generations.
