The manager of the convenience store 'Tenderness, Mojiko Koganemura Branch'. He is 30 years old. He is the third of the five Shiba siblings. Members of his older brother Tsugi's fan club call him 'Mic-chan', his younger sister Jewel calls him 'Mitsu-oppa', Mitsuri calls him 'Phero-Manager', and others call him Shiba. He is a handsome man who exudes pheromones regardless of gender or age and is kind to everyone. He seems to truly love the convenience store where he works. Something must have happened in his past; in the only glimpse of his history, he once mentioned during small talk, "There was a child who said something like that before." That incident is likely the reason why Shiba came to love and work so hard at the convenience store.

The younger sister of Mitsuhiko and Nihiko. She is the youngest and the only daughter among the five Shiba siblings. As expected of Mitsuhiko's sister, she is mentioned to be an incredible beauty. There is a significant age gap between her and her older brothers, and she is currently a high school student. She has a history of suddenly showing up at Shiba's convenience store. After being lightly scolded by Shiba and Tsugi, who rushed back to the store, and having a consultation with them, Jewel declared, "I'm going to work at my brothers' convenience store too." Currently, she is working a desk job on the floor above the store until she finds what she truly wants to do.

A part-time worker at the Tenderness convenience store. She is around 40 years old. She is a housewife with a husband and a son. Her hobby is drawing manga; she posts manga inspired by Shiba, which has received good reviews, ranking high and gaining fans. Her husband also supports her. She enjoys observing the daily occurrences at the convenience store from a third-party perspective to get material, and she has a kind heart.

Mitsuhiko's second older brother. He is two years older than Mitsuhiko. He is called by his nickname 'Tsugi' (meaning 'second') rather than his real name. Unlike his younger brother Mitsuhiko, he has a rugged 'manly man' style with thick hair and a beard, and he works as a 'Jack-of-all-trades'. He mostly eats at Shiba's convenience store, and the brothers share a deep bond, helping each other out. He operates throughout the Kyushu region.

A healthy elderly man who wears unique fashion and rides around the neighborhood on a bright red tricycle. Perhaps because of his tricycle, the local children call him 'Grandpa Red'. He is a source of information.

A part-time worker at the Tenderness convenience store. He is a bit blunt and good at pointing out the cold, hard facts.
