The main character is the Devil King. He is a powerful figure from the Devil World but is now stuck working part - time in the human world. Another important character is the human girl who befriends him or at least gets involved in his life in some way. She represents the normal human perspective in the story. And of course, his minions who also accompany him to the human world and are part of his new part - time working crew are also main characters in a sense.
The Devil King is one of the main characters. He has to adapt to the human world and work part - time. There is also his female follower, who also plays an important role in the story as they navigate through the human world together.
The main plot involves the Devil King and his minions having to work part - time jobs in the human world. They face various challenges while trying to blend in and survive, like dealing with human co - workers and the mundanity of human jobs.
Since I haven't read it, I can't say for sure. But it's likely that the devil is one of the main characters, given the title.
The main character is Satan. He is the devil who has to adapt to the human world and work part - time jobs.
There is also a human character who befriends the devil. She helps him understand the ways of the human world. Her kindness and patience contrast with the devil's brash and sometimes clueless nature. Another important character is the devil's underling from the devil world who sometimes shows up in the human world and causes more chaos with his attempts to follow the devil's orders in a world he doesn't understand.
The main character is the devil. His name is Sadao Maou. His human form has a normal life in the human world, working at MgRonald's. Emilia, who is also from Ente Isla, is another important character. She has her own goals and her relationship with Sadao is complex. Chiho, a human girl who has a crush on Sadao, also plays a significant role in the story as she gets involved in the world of the devil and his friends.
Satan, also known as Maou Sadao in the human world, is a central figure. He's trying to take over the world but gets sidetracked by human life. Emi Yusa, or Emilia Justina in her true form, is a strong female character who opposes Satan. Alciel, whose real name is Shiro Ashiya, is always by Satan's side, and they have a lot of comical exchanges as they navigate the human world together.
The main character is the devil who has to work part - time. There are also probably some human characters he interacts with.
Emi Yusa is also a main character. She has a complex relationship with the Devil as they are from different worlds but are also connected in the human world.
Emi Yusa is also a main character. She is an enemy of the Devil in their original world but in the human world, there are all kinds of interactions between them. And then there's Chiho Sasaki, a human girl who has a crush on Sadao and often gets involved in their affairs.
The devil is definitely one of the main characters. He has his own goals and motives, like trying to survive in the human world while still having his devilish nature. Then there's the girl who has a special connection with him. She might be a human, but she gets dragged into the devil's world in a way. And don't forget his workmates. They are there in the part - time job setting and add to the humor and the overall story. They might not be as powerful as the devil, but they are important for the story's development.
