The owner of the sandwich shop. She looks quite young for an owner. Her personality is energetic and passionate; she is brave and good with her fists. She also has a bit of a tsundere side. She treats customers with respect and seems to cherish her shop dearly. While she values customers, she tries her best to just take orders and send blacklisted people and Aro away as quickly as possible. She has purple hair and green eyes, wears a green visor and a teal scarf, and goes around in brown clothes with green gloves. She carries around her precious brown BB gun; if you look down on her and approach, be careful as you might get a 'true education' from the kickboxing skills she learned in the past. Her hobby is picking up trash.

The cook at the sandwich shop. He is Russian but moved to Korea. His personality is quite... not tsundere, but easygoing. He hates having his beanie taken off; if it is removed, he becomes very violent. It seems the beanie has the power to make one's teeth stick together when worn and cause a violent personality when removed. He wears a teal beanie and a khaki hoodie, and his house is full of firearms—his most prized possessions are his minigun and bazooka. His hobby is shooting at street shooting galleries (he says he's won quite a few dolls this way).

A sandwich shop customer who just turned 20. He is semi-blacklisted. A 'question killer' who is full of curiosity, with a bright and cheerful personality. He is a regular at this shop and has a father who is a visiting engineer. His older brother is a gamer (to put it bluntly, he's unemployed). He wears a visor that covers his eyes. He started using the visor to hide a childhood trauma related to his eyes, and it filters out majorly cruel scenes. He wears a varsity jacket and blue sneakers, and usually spends his time wandering streets or markets asking questions and buying things. He really likes a scientist named Deon because Deon has wings and answers his questions well. Because of that, he sometimes wears fake wings and horns.
