Gorō is a supporting character in the anime Shin Dokonjo Gaeru, known in the original series as Dokonjo Gaeru. Despite his small stature, he is a loyal friend and a consistent presence in the daily life of the main protagonist, Hiroshi Kaizuka. He is presented as being only a year younger than Hiroshi, yet he always addresses Hiroshi with the respectful title of senpai, demonstrating his admiration and the dynamic of their friendship where he often plays the role of a devoted, if sometimes less assertive, companion.

In terms of his role within the story, Gorō functions primarily as Hiroshi’s sidekick. He is frequently seen alongside Hiroshi and his girlfriend, Kyoko Yoshizawa, as they navigate the humorous misadventures that make up the series. While Hiroshi often takes the lead and gets into trouble, Gorō is typically there to provide support, react to the chaos, and participate in the various pranks and schemes. The series establishes that he has a girlfriend named Misaka, indicating he has his own life and relationships outside of his friendship with Hiroshi, though these are less central to the main narrative.

Regarding development, relatively little information is available about any significant personal growth or change in Gorō's character throughout the series. His personality and circumstances appear to be fairly static, serving as a reliable and familiar element within the ensemble cast. He does not possess any extraordinary abilities or notable physical traits beyond being recognized for his short height, which is a defining characteristic. His value to the series lies in his steadfast loyalty and his role as a dependable friend who helps ground the more impulsive and rambunctious actions of Hiroshi and the frog Pyonkichi.
