Mecha Girl MAX Overhaul: Mecha Girls of Every Type Come Knocking

[Racing Girl Redemption] + [Open a Shop and Level Up] + [Everyday Flirting] + [Absurd Comedy] In this world, every girl awakens the talent to become a “racing girl” when she comes of age, transforming into a particular kind of mechanical vehicle. Just after turning eighteen, Xiang Kaiche inherits his parents' tuning shop and gets a cheat right away: the Superspeed Modification Bench. When a racing girl transforms into vehicle form on the bench, it triggers [Superspeed Modification]. He can choose one component and evolve it into a [Superspeed Part] with off-the-charts performance! The transformation is so powerful that it surpasses anything in this world. It maxes out the vehicle's performance and even grants it skills like divine blessings. Racing Girl Driver: My racing girl is loyal, faithful to me and me alone! Xiang Kaiche: Last night, she snuck over and said she wanted to downgrade her two headlights to D-rank. Auto Shop A: We only modify cars. We won't take any other jobs. Xiang Kaiche: Surrounded by flowers, why stop for just one peony? Auto Shop B: Certified as the best in the world! Our parts can boost performance by 30%! Xiang Kaiche: My racing girls... I mean, my customers' racing girls, get at least a 300% boost. Many of the campus's dazzling, breathtaking racing girls have been mocked and looked down on because their talents awakened at such a low rank, leaving them struggling to make a career as drivers. But... When they emerge from [Superspeed Modification] and return to the professional stage, a single upgraded part is enough to astonish the world and send it into an uproar!
