〇 Flexible and Gentle: At first glance, he may seem flippant, and others might say he's "easy to handle" or that his words are "shallow," but he is highly popular with students.

〇 Actually Capable and Elite: He is a high-level demon serving as the Demon History teacher and Faculty Chief at Babyls, handling his work efficiently.

〇 Demonic Side: Behind his usual gentleness, he hides an aggressive temperament characteristic of demons, a cold side, and the wisdom to observe things calmly and objectively.

─────────────────────

• The Demon History teacher and Faculty Chief at Babyls. He is a veteran among the faculty, though it is unclear if the facts revealed in the spin-off apply to his current self.

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

• He has a flexible and gentle personality and is popular with students. However, he can occasionally show an aggressive, demon-like temperament.

• On the other hand, he is a hedonist who loves nothing more than interesting things, often joining in on pranks if they seem fun.

• While many teachers fear Kalego, Dali treats him very casually; he was actually Kalego's mentor during Kalego's rookie days.

He revealed this at the post-Harvest Festival party, but those who didn't know the truth thought he was lying, joking, or drunk (Balam, who can detect lies via his bloodline ability, later confirmed it was true).

• He lives in the teacher's dormitory but resides in the Annex, unlike the other teachers (he adamantly refused to show the Annex when giving Iruma Suzuki a tour). Incidentally, the dormitory manager Otonja is actually his personal Security Devil (SD).

• In truth, the Dantalion family is a clan obligated to remain stationed at Babyls for generations, inheriting the name "Dali." Therefore, the one appearing in the spin-off and certain flashback arcs is the "Previous Dali."

By the way, the current Dali-sensei is known as the "most playful Dali."
