Trivial Characters

This list contains characters who have only been introduced in the story briefly or have been mentioned a few times at some point through the game.

The Demon King
The Demon King (悪魔の王) is the current ruler of Devildom, although he resides at the bottom of Devildom as he has no interest in the affairs of the three worlds. His son, Diavolo rules Devildom, but he hasn't been crowned as the next king yet. He was also responsible for the brothers ranking and "age" when they fell from the Celestial Realm, with Lucifer being the oldest and most powerful and Belphegor being the youngest and the weakest. Despite being youngest, Satan was deemed the fourth oldest because of his power instead of his actual age.

According to Luke, he has not seen the Demon King since a ceremony 1,000 years ago. This could’ve been his last public appearance.

Grisella
Grisella (ドリセラ) is a witch who resides in the human world. She was introduced in Lesson 10 when MC, Lucifer, Satan, and Mammon decide to journey to London to seek her help to return Lucifer and Satan back to their original bodies when the two swapped due to Grisella's magical book being touched by them at the same time. She was later killed in a train by her supposed-to-be apprentice, Noah.

Noah
Noah (ノア) yearns to become Grisella's apprentice. However, he kills her by stabbing her with a knife in Lesson 11 due to Grisella continuously refusing Noah to be her apprentice. Grisella's spirit said that Noah once told her that he performs throwing knives in his circus act. She later reveals that she didn't take apprentices because she was aware of her impending death, but did not anticipate that Noah would kill her because of her rejection.

Mephistopheles
In the first-ever RAD Newspaper Club chat, Mephistopheles (メフィストフェレス) was in 10th place in the unofficial results, but he and Mammon were disqualified due to falsified ballots. This was later commented on by Asmodeus, Satan, and Leviathan, with the latter being upset he only made the list after the disqualifications.

He used to be the president of the Newspaper Club but was forced to step down, due in part to falsified ballots but also to the errant posts made by the Newspaper Club soon after.

Astaroth
In the first-ever RAD Newspaper Club chat, Astaroth (アスタロト) was not on the unofficial results, but he earned 9th place after Mephistopheles and Mammon were disqualified due to falsified ballots.

Dantalion
Satan invited MC to the Museum, which is holding an event featuring the art of a mysterious painter that never shows their face in public. The art exposes the viewer's core, while their core also burns red and white with passion and lust. Satan tells the MC that rumors say that Dantalion (ダンタリオン) is that artist, but is unconfirmed.

Diaval
Diaval (ディアバル) is demon who had gone to the human world as an exchange student, supposedly with Belphegor.

Michael
Michael (ミカエル) is an archangel often brought up by Luke, saying he reports to Michael directly, which implies he's in some authority position at the Celestial Realm.

Michael loves sweets of all kinds, according to Luke in Lesson 5-12.

In Lesson 23-3, the brothers reveal that Michael always admired and loved Lucifer.

In Lesson 23-5, Barbatos refers to Michael as "Michael the Archangel" and mentions that he's also the present leader of the Celestial Realm's legion of angels and the guardian angel of confectioners.

[unsure of lesson] It is revealed that Micheal used to teach Mammon but didn't know how to deal with him so Lucifer took over.

Lucifugus
Lucifugus (ルキフグス), Asmodeus, and several others throw a party Lucifugus' house. Asmodeus invited the MC to the party, saying they will pick up MC after class and hinting at getting another partner, a.k.a. make a pact with another demon.

Mahazael
Mahazael (マハザエル) is a real estate agent that tells Mammon that he has to sign a two-year contract and pay monthly rent to live on his own. Mammon believes it is a scam and tells him to "shove his two-year contract where the sun don't shine." Mahazael then tells Mammon that he will inform Diavolo and Lucifer if Mammon didn't pay.

Maddi
A famous witch who is known as the Great Witch Maddi (マディー) and possesses great power despite being a human. In The Escorts, Diavolo asks Lucifer and Satan to escort her while she's in Devildom for they are her "type". She once aggressively pursued Diavolo and refused to return to the human world unless he married her, which he had a hard time convincing her to give up. Mammon had gone home with her one time, and the experience left him traumatic for he had nightmares and stopped spending money. According to Lucifer, her beauty rivals the succubus who won the beauty portion in the Queen Contest.

Little D.s
