Rikako Ota is the daughter of RGO owner Kazuo Ota, and an aspiring tuner herself. Known to inherit RGO from her father after his retirement, she follows her father's footsteps as a tuner by engaging in tuning herself. When Eiji Kamiya comes over to Tokyo and works for RGO, she tunes his Evo along with him and even comes along during his battle with the Devil Z and Blackbird. Her first solo tuning work was with the Devil Z, after Akio specifically asked for her help in tuning the Z's engine. Her addition of a dry sump lubrication system on the Z's L28 engine resulted in Akio's victory against Kijima's FC and the Blackbird. Since then, Jun Kitami has entrusted her with tuning the Devil Z, as he told her before the race with the Z's race with Kijima and Blackbird that he would no longer tune the Devil Z.
