Description
Genta Doi is initially introduced as an elementary school classmate of Akira Ono and Haruo Yaguchi. He admires Akira for her beauty, intelligence, and affluent background, frequently attempting to make her his fiancé despite consistent rejections.

He reappears during high school, enrolling at the same institution as Haruo. While his earlier persona centers on persistent yet unsuccessful romantic pursuits toward Akira, his high school years show him associating with Haruo and their mutual friend Kotaro Miyao, indicating a shift toward friendship dynamics. His personality during this phase is described as snobby, with attempts to present himself as cultured and suave.

In the spin-off sequel "Hi Score Girl DASH," set when he is approximately 28 years old, Genta works as a co-teacher alongside Koharu Hidaka at their former high school. His awareness of Koharu’s history as a skilled arcade gamer highlights his continued connection to the core group’s past.

Physical descriptions consistently note Genta has dark brown hair and purple (aubergine) eyes. His background includes unnamed older and younger siblings.
