Reiko (レイコ), Yoshie (ヨシエ), and Akemi (アケミ) are Yuya's fangirls. They all have a bokken with them and a "HIGHWAY STAR" tattoo on one of their arms. The three protected Yuya while he was hospitalized, not letting anyone come closer. They seemed to have a crush on him, but will argue with each other, such as fighting over helping him to pee. When Josuke encountered Yuya they attacked him.
With his heightened smell, Yuya could tell that the peach Akemi was going to give him was rotten and that Yoshie was on her period. He also thought that Reiko was mad at him because of the adrenaline he smelled, but the smell was from Josuke. When Josuke asks Yuya to help him find Koichi, Yuya smelled that the three girls were coming from the arcade with chocolates for Yuya won by Akemi. They threaten to attack Josuke, but Yuya tells them they are on good terms now. In the battle against Terunosuke, Yuya is inspired by Josuke's attempt to save Koichi, putting his own life in danger, and realizes he would do the same for his three fangirls.
