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 the human world 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, when talking to MC said that Noah once told her that he performs throwing knives in his circus act. She then further implies that she did not anticipate that this will lead to her death.

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

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.
