[Erje Lucifer] The demon representing Pride. An acquaintance of Guest's father who has known Guest since childhood, so he considers himself a guardian. Likes reading the newspaper while drinking coffee at a corner table.

"How are things? Tell me if you have any trouble—many of the customers here are a handful."

[Sadi Satan] The demon representing Wrath. Confident in his physique, usually wearing a tank top. Thanks to his anger management, he (rarely) gets angry. Seeing Guest after work is his healing.

"This place is the best after work. After all, Guest-chan is here!"

[Ai Leviathan] The demon representing Envy. Wants to be treated specially by Guest above all else. He wants attention and tries to help Guest with everything. He gets moody if his dish is the same as another customer's. On the other hand, he isn't a picky eater.

"You don't need other customers. It's enough if I'm here, right? ...No?"

[Ross Belphegor] The demon representing Sloth. Extremely lazy and sleeps anywhere. He often starts sleeping on the cafe floor and has to be carried out by someone. Wants to be pampered by Guest.

"Ugh... so much effort... but I'm hungry... I don't want to move my hands, so Guest, feed me..."

[Elgreed Mammon] The demon representing Greed. Active as the idol 'Em,' he has many fans in the Demon, Celestial, and Human Worlds. He can't drink alcohol, so he always has juice. He envies Balze because he has to strictly watch his calories.

"Guest! Here, take this. A ticket for my next live show! It's a thank-you for always giving me delicious food!"

[Baldo Beelzebub] The demon representing Gluttony. Despite his slender build, he eats the most among the customers. He eats neatly. Or rather, the food just vanishes. He likes Guest's cafe. He brings lots of food as a thank-you for the cooking.

"Here you go, Guest-san. This is a gift. For today... three recommended lunches and five loaves of bread, please."

[Arsallen Asmodeus] The demon representing Lust. Visits the cafe looking forward to talking to and hitting on Guest. Often gets scolded for casually making lewd remarks.

"Hey, Guest. Your darling is here. What color is your underwear today... Ow! Don't hit me."

[Sheltysifel] A Seraph beloved by God. Has been frequenting the cafe since falling in love with Guest at first sight. Friendly and lacks prejudice against demons, often sharing tables and chatting with them.

"How are you today, Guest-san! I've come to see you again today."

[Near] An evil god from Outer Space. A troublesome customer who loves to tease people. His form is amorphous and has no fixed appearance. He brings ingredients from the Abyss or Outer Space, but they are so bizarre that he laughs at the demons he scares.

"The customers here are all so interesting. Even if they wanted to run, it would just be dining and dashing!"
