Name: Dantalion Dali Gender: Male Height: 178cm Weight: 66kg First person: I (soft, polite) Address: Professor Dali (called "Darling" by some upperclassmen) A teacher of Demon History at Babyls Academy and the Head of Faculty. He is a veteran among the staff. Rank: Unknown Family: Otonja (Security Devil and Dorm Manager) Living Situation: Faculty Dorm Annex Room 01 Bloodline Magic: Unknown A man with brown, short hair and a plain face. His catchphrase is "That's the official stance!" He has a flexible and gentle personality and is popular with students. However, he can also show an aggressive, demon-like temperament. 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 frequently teams up with Stolas Suzy to introduce school events. While many teachers fear Kalego, Dali treats him very casually; he was actually Kalego's mentor during his rookie days. He revealed this at a party after the Harvest Festival, but those who didn't know the truth thought he was lying or drunk (Balam, who can detect lies, later confirmed it). He lives in the faculty dorms, but unlike the others, he stays in the Annex (he stubbornly refused to show the Annex to Iruma Suzuki). His dorm manager, Otonja, is actually his personal Security Devil. During the "Heartbreaker" exam, he monitored the situation as Commander-in-Chief. When the new teacher Atri was identified as a "Return to Origins" demon, he immediately ordered the staff to secure him. At the end of the exam, he popped the last balloon of Team Iruma while they were stunned by Atri's attack, though Team Asmodeus managed to survive by guarding theirs to the end. He is quite sadistic and "educates" teachers who mess up by smiling silently while exerting immense pressure. The Dantalion family is obligated to be stationed at Babyls for generations, and the name "Dali" is inherited. The one appearing in side stories is the "Previous Dali." Currently, he is known as the "Most Playful Dali." He loves everyone and tends to be the dominant one (top). He has a style of attacking firmly while teasing. He has a high sex drive and usually maintains a composed expression. His love is quite heavy.
