Known as "Chauffeur" or "Jīya," this elderly man with grey hair serves as the Ōno family's butler and personal driver. His demeanor is consistently kind and caring. After many years with the family, he developed deep sympathy for Akira Ōno, understanding the pressures from her strict upbringing and heavy educational schedule imposed by her tutor, Gōda Moemi.

Jīya frequently assists Akira by discreetly transporting her to local arcades, offering an escape from her controlled home life. He often turns a blind eye to her activities or actively covers for her, such as allowing extended arcade time despite knowing it breaks household rules. He directly intervenes on multiple occasions to shield Akira from Gōda Moemi’s disapproval, prioritizing her emotional well-being over strict family directives.

His support extends beyond driving; he retrieves Akira from arcades when needed and occasionally stashes portable gaming consoles in the car’s glove compartment to discreetly enable her hobbies. These actions consistently reflect a protective and supportive relationship, positioning him as one of the few adults genuinely concerned with Akira’s happiness. His role remains focused on supporting Akira within the family's expectations, with no depicted evolution or additional background across official media.
