Name: Dantalion Dali (Note: Originally "Dandalion" in the magazine, corrected to "Dantalion" in the volume release) Gender: Male Height: 178cm Weight: 66kg First person: I (soft, polite) Address: Dali-sensei (called "Darling" by some upperclassmen) A Magic History teacher at Babyls Academy for Demons and the Chief of the Faculty. He is a veteran among the teachers, though facts revealed in the spin-off make it unclear if they apply to his current self. Rank: Unknown Family: Otonja (Security Devil and Dormitory Manager) Living Situation: Faculty Dormitory Annex, Room 01 Bloodline Magic: Unknown A male teacher with short brown hair and an ordinary face. His catchphrase is "That's the official stance!" He has a flexible and mild-mannered personality and is popular with students. However, he can sometimes show an aggressive demonic nature. On the other hand, he is a hedonist who loves interesting things above all else, often going along with pranks if they seem fun. He often teams up with Stolas Suzy to introduce school events. While many teachers fear Kalego, Dali treats him quite casually; he was actually Kalego's mentor during his rookie days. He revealed this at a wrap-up party after the Harvest Festival, but those who didn't know the fact thought he was lying, joking, or drunk (Balam, who can detect lies, later confirmed it was true). He lives in the faculty dormitory, but unlike other teachers, he lives in the Annex (he stubbornly refused to show the Annex when guiding Iruma Suzuki through the dorms). By the way, the dorm manager Otonja is actually his Security Devil (SD). During the "Heartbreaker" exam, he monitored the overall situation as the General Commander. When the new teacher Atri was identified as a "Return to Origins," he immediately ordered the teachers to secure him. Near the end of the exam, he popped the last balloon of Team Iruma—who were stunned by the events following Atri's attack—almost like a sneak attack, but Team Asmodeus survived by defending their balloon with their last strength. He is quite sadistic and educates teachers who mess up by pressuring them with a silent, smiling face. The Dantalion family is a lineage obligated to be stationed at Babyls for generations, inheriting the name "Dali." Therefore, the one appearing in spin-offs or past arcs is the "Previous Dali." → Dantalion Dali (Previous) Incidentally, the current Dali-sensei is called the "most playful Dali." He loves everyone and takes the lead (dominant). He's the type to tease a little but then strike hard. High libido. He usually keeps a composed face. His love is quite heavy.
