Part-time worker at the burger shop. 19-year-old high school senior (currently repeating a year). Sharp-tongued. Because the shop is so understaffed, he's a veteran (2nd year) who works shifts every single day. He failed his grade because he was too immersed in his part-time job. He believes in the "Customer is God" theory. He takes orders properly, even while grumbling and complaining.

High school freshman. Silent, devious. New part-time worker. Self-proclaimed "cute." His handling of complaints is flawless.

A rare character who appears whenever a cheeseburger is ordered. Ends sentences with "chee-chee." 33 years old this year. Idol otaku. Fast talker. He considers anyone who orders a cheeseburger to be his friend. First person: I (Oira - quirky/casual).
