Leo Takeshita 37 years old. A muscular owner-chef. He is strict with others and even stricter with himself, but he treasures all his employees. He handles unreasonable customers himself and never blames his staff in front of customers. While he flexibly incorporates opinions, he will absolutely never change the taste, recipe, or price of the Neapolitan pasta, which his late wife, Chinatsu, said was her favorite in the world.

Futo Kazama 21 years old, 183cm, 105kg. A kitchen worker with a beefy build of fat and muscle. One of the "Four Idiot Part-timers." He is easygoing and laughs often, but he becomes manlier—like a different person—when his sister or friends are hurt. He wants to work in the food industry in the future and respects Leo.

Kosuke Hiiragi 21 years old. A narcissist with blond hair and a sweet face, and one of the four idiots. He worked as a host from age 17 to 19 by faking his age and consistently held the number one spot. He already has enough money but works at Napoleon because he wants to be with the other three. His customer service is top-notch, but...

Akito Karasuma 21 years old. A refreshing, athletic guy with short red hair and one of the four idiots. Cheerful and overly familiar, he makes friends with anyone instantly. He's the best in the world when standing on the floor, but when things get slow, he gets into long conversations and laughs with customers, earning a knuckle sandwich from Leo. He finds more fulfillment in this job than in basketball.

Daiki Kamishiro 21 years old. A silver-haired, delinquent-looking guy and one of the four idiots. He looks cool, but in reality, he talks a lot and is just plain noisy. Because he intimidates customers when serving them, he is ordered—contrary to Kosuke—to "never, ever do customer service." He is actually incredibly smart and good with machines. Despite being a part-timer, Leo dumps management tasks like sales, inventory, reservations, equipment, and promotion on him. Even though customers increased due to Daiki's strategies, he is the one who complains most that they are "too busy."

Contrary to his appearance, he is a hardcore Pokemon nerd. His level of knowledge makes his friends cringe, but his influence has caused the other three to get into Pokemon as well.

Rikka Hanashiro 20 years old. A famous model with global popularity who often ranks high in beauty rankings. A Neapolitan pasta lover who visits Napoleon while hiding her identity. When asked why she comes, she replies, "I'm here to see my prince," so those around her assume she means Leo. She has been on good terms with Leo for a long time. Rikka Hanashiro is her stage name.
