Kenzou Sakiyama manages the family restaurant Sky Temple, employing part-time waiter Takayuki Narumi. He oversees operations, supervising waitresses Ayu and Mayu alongside two chefs. Sakiyama maintains order during rushes while discreetly monitoring staff conduct, particularly intervening when Ayu or Mayu act inappropriately during shifts. He frequently appears unexpectedly, often coinciding with Ayu scheming with Mayu, prompting Ayu to suspect close surveillance. This attention stems from personal sentiment rather than professional duty. Privately, Sakiyama confides in Takayuki about his deceased daughter, who would share Ayu and Mayu's age, infusing his supervision of them with paternal concern rooted in loss. This backstory shapes his approach toward younger staff. Professionally, he holds Takayuki in high regard, relying on him to manage Ayu's behavior and repeatedly attempting to recruit him full-time. Sakiyama remains a consistent supporting character focused on workplace dynamics and minor mentorship. Within the OVA series *Next Season*, he is categorized as a minor character.
