The current owner of Rokuhoudou, in charge of tea and the floor. He inherited the café from his grandfather. A massive cat lover who dotes on the shop's mascot cat, Kinako; his excitement when the topic of cats comes up is intense. Although he is unaware of it himself, he is terrible at cooking and almost always produces mysterious objects, so the other three staff members try their best to keep him out of the kitchen. He wears a kimono even in his private life, whether going out or relaxing at home. Often described as an intellectual, bespectacled handsome man. He usually speaks in polite Japanese. Occasionally, his politeness slips. First person: I (polite), but switches to I (casual) when talking to his twin brother, Yakyo.

In charge of coffee and the floor at Rokuhoudou. The mood maker of the group. He is half-Italian and half-Japanese, with an Italian mother and a Japanese father. He has three younger siblings. He lived a rough life as a boy but reformed after meeting a bar master. He is a barista who trained in his birthplace, Italy. A reliable, older-brother figure who says, "My dream is to make everyone in the world smile," and "So I want to start by making the people I interact with smile." He is athletic and has many hobbies. He is a positive man of action who tries anything that interests him. He also likes to draw, but his artistic sense is very unique (unbeknownst to him), so his latte art turns into mysterious patterns. The contrast between the excellent taste and the bizarre latte art has become a specialty in its own right, earning high praise on review sites as something "you must drink at least once." He is often the target of Tsubaki's sharp tongue. He speaks energetically. First person: I (casual/masculine).

In charge of cooking and tableware at Rokuhoudou. He is also a ceramic artist and runs a pottery class nearby. He was Sui's classmate and friend in middle school. Despite his age, his hobbies and demeanor are very refined and calm. He likes period dramas and enka music, making him popular with older people. He reunited with Sui when Sui, having just inherited Rokuhoudou, was looking for tableware to use in the shop. Wanting to help in any way he could (and knowing that Sui's cooking was disastrous), he began working as the chef. Thanks to his uncle's influence, he is skilled at gardening and growing vegetables. He was also taught table tennis by his uncle, a former national athlete, and his personality changes when it comes to the sport. Sui calls him the "Sleeping Dragon." Characterized by a gentle, polite tone. First person: I (polite).

In charge of sweets at Rokuhoudou. The youngest of the four. A Japanese confectionery artisan and graduate of a pastry school. While his skills are high, he struggled with deep interpersonal relationships for certain reasons and moved between various sweet shops. His hobby is visiting different shops to research sweets. He is a big eater and can finish surprising amounts of food with ease. He is sensitive to heat and cold, so he truly welcomes the arrival of autumn. He has a sharp tongue and often plays the straight man to Gure's antics. He is a tsundere who has trouble being honest and uses a blunt, biting tone. He becomes talkative when the subject is sweets, but when praised, he gets stiff and can't show his joy, saying things like "It's... just normal, right?" While serving customers, he uses professional, polite language, but he lacks the soft atmosphere of Sui or Tokitaka, giving off a sharper impression. First person: I (soft/boyish).
