Description
Jōji Tanaka is the grandson of a frequent visitor to the health and welfare office and serves as a supporting character in the series. He is a 22-year-old banker, a job that reflects a responsible and professional demeanor. His most recognizable personality trait is his strong sense of responsibility, which frames his interactions with others. He is characterized as a try-hard type, someone who puts in significant effort and dedication into his endeavors.

Jōji shares a long history with his childhood friend and rival, Yutaka Hasebe, having gone to school with him. This friendship is defined by a deep-seated and one-sided competitive rivalry, as Jōji has never managed to beat the effortless genius of Yutaka at anything. This dynamic has led to an awkward friendship where Jōji harbors feelings of resentment and inferiority. In one notable instance, his frustration boils over in a drunken rant where he complains that Yutaka is wasting his talents on a mundane job as a civil servant and is pursuing a plain girl like Lucy Yamagami. This complex history makes him a foil to Yutaka, representing the hard worker who is perpetually overshadowed by someone with natural talent.

Within the story's setting of a government office, Jōji is primarily connected through his grandmother, affectionately known as Mrs. Tanaka, who frequents the office and tries to set him up with the soft-spoken employee Saya Miyoshi. This setup creates an awkward dynamic between Jōji and Saya, as he is often described as infiltrating her space for trivial reasons, though she eventually develops a better feeling toward him. Another character, Chihaya Megumi, even hints that Jōji might have unrequited feelings not for Saya, but for Yutaka, adding a layer of unspoken complexity to his intense rivalry.

Throughout the series, Jōji's development is subtle, primarily focusing on his relationship with his long-standing inferiority complex. His motivations are largely driven by his desire to compete with and finally surpass Yutaka, as well as by the expectations placed on him by his grandmother and his own responsible nature. While not possessing any special abilities, his notable trait is his dedication to his work as a banker, which requires precision and responsibility, contrasting with Yutaka's more lackadaisical approach to his own civil service job.
