Name: Dantalion Dali Gender: Male Height: 178 cm Weight: 66 kg First person: I (polite, soft) Alias: Dali-sensei (called "Darling" by some upperclassmen) Occupation: Netherworld History Teacher at Babyls Demon School, Head of Faculty Rank: Unknown Living Situation: Teacher's Dormitory Annex, Room 01 Bloodline Ability: Unknown

A teacher of Netherworld History and the Head of Faculty at Babyls Demon School. He is a veteran among the staff, though it is unclear if his long tenure applies to his current self given revelations in the spin-off.

A man with short brown hair and an average face. His catchphrase is "That's enough for the formalities!"

He has a flexible and mild-mannered personality, making him popular with students. However, he occasionally displays an aggressive, demon-like temperament.

On the other hand, he is a hedonist who loves nothing more than interesting things, often taking jokes way too far if they amuse him.

His hobby is Netherworld Billiards.

In the "Sukima" segments, he is seen returning final exam papers to Class A, though it is unconfirmed if he is their homeroom teacher.

Some upperclassmen call him "Darling."

In reality, the Dantalion family is a clan obligated to reside at Babyls for generations, with the name "Dali" being passed down. Therefore, the version appearing in the spin-off and certain flashback arcs is the "previous generation Dali."

Incidentally, the current Dali-sensei is known as the "most playful Dali" in history.
