**Challengers** (参戦者 *Sansensha*?) is the two hundred-and-eightieth chapter of Osamu Nishi's *Welcome to Demon School! Iruma-kun*.

## Summary

In the morning, Opera wakes and serves breakfast to Iruma. After that, Opera prepares for school as a teacher. Inside the school, students comment on how Opera looks good, and teachers comment on how Opera swiftly complete the work. After completing the tasks, Opera sends something to someone through their phone.

In another place, it is revealed that Opera sent a selfie of the previous class to Kalego's phone. After seeing the selfie, Kalego comments on how carefree Opera is. A second person asks Kalego if there is an emergency. Kalego denies it and tells the second person to continue, who is revealed to be Security Chief Azazel Henri. Henri asks Kalego if it is *OK* to leave the school, as the principal is also absent. Kalego replies it isn't ideal, but it shouldn't cause any issues. After that, Kalego mentions his main reason for the meeting, that he wants to meet his brother. Henri tells him that he has to stop him and can't meet Narnia since he has been summoned to Babel for an important matter.

As Kalego questions this, Henri reminds him of the disappearance of one of the Thirteen Crowns, Behemolt. Since his whereabouts are still unknown, they can't leave his seat empty for too long. Therefore, with this in mind, Narnia was recommended as the new member of the Thirteen Crowns, shocking Kalego. As Kalego expresses his shock at Narnia being one of the crowns, Henri tells him that Narnia is just a candidate, along with Barbatos Bachiko and some other high-ranking demons. Henry further explains that they are currently being interviewed by the Three Greats, during which communication from the outside world isn't possible. After the current crowns and the Three Greats have conferred, the newest crowns will be decided. It is also possible that some of the current crowns may also get replaced. After everything is sorted out, a Deviculum will be planned where the name of the new crowns will be revealed and will serve as a debut for the new crowns, and there is also a possibility that the "Trickster Plan" may also be revealed. He tells Kalego that this Deviculum will, no doubt, go down in the history of the Netherworld.

Henri explains to him that it is impossible to meet Narnia right now, even if Kalego is his brother. But Kalego interrupts him by asking if he could meet his brother if he attends the party. As Henri is startled by this, Kalego tells him he will prepare for the Deviculum. Kalego asks Henri if there is any problem. Henri asks in return that isn't the Naberius Clan known for having a "no party policy." Kalego explains that it's true that they made a rule to forgo parties to always stay alert. But, "Once you bite down on something, keep biting even if you're down to your last fang" is another one of their rules, and he likes that one more. Henri complies and hands him a Deviculum invitation card, telling him that since the Deviculum will be managed by the border patrol, he asks Kalego not to cause any trouble. Kalego takes the invitation and walks out, telling Henri that he will *keep that in mind.*
