**Opera-Sensei** (オペラ先生 *Opera Sensei*?) is the two hundred-and-seventy-seventh chapter of Osamu Nishi's *Welcome to Demon School! Iruma-kun*.

## Summary

Opera enters Sullivan's room to witness a depressed chair demon. Upset that he let his angry side out in front of his grandson and the other students during the Heartbreaker Challenge. Wanting to apologize for his behavior but is conflicted with going with the other Three Greats at Babel Tower. To the chair demon's surprise, Opera changes the subject by asking Sullivan if he may become a teacher in Babyls. Back with the meeting between Opera and Kalego, he was surprised as Sullivan but more horrified.

Opera explains since Kalego and the principal will be absent, they will need a replacement for Atori and extra eyes on Shiida. And so, Opera became a new member of the Babyls staff.

He introduces himself to the other staff, shocked and confused by the news. But only Dali shows humor to this, and Robin is excited to hear he has a new Kouhai to mentor. Kalego silenced him while the Momonoki tried to apologize. However, it didn't bother Opera, liking the idea of being a Kouhai. He then meets up with the student council president, who is delighted to hear they'll see each other more often. Ameri then asks Opera if he has the time to train her and the student council. He agrees to her requests despite the other council members' dismay.

Opera continues his tour of Babyls meeting the rest of the staff, while the students gossip over the news of the principal's security devil as the new teacher. They review his coolness and how lucky the Abnormal Class is to have him as their teacher. Their thoughts on Opera being a teacher are very concerned about his lessons. Not sure what he'll do, but they keep their guard up and ready for anything. Opera then offers a tea party for the misfits to get to know them. Surprised and confused, the class follows Opera by his request to not use their wings.

Outside of Babyls, Opera and Shiida sit together with their tea. Though Opera is ashamed, wondering why the misfits are taking so long. It turns out that Opera's tea party is actually a surprise lesson. While he and Shiida are atop a spire, the misfits are stuck at the bottom, forced to climb up. Only their bodies and the magic they've learned are allowed, not using their wings, familiars, or bloodline magic. Opera's first lesson has begun, and it's just evil.
