Storyline

My name is Daichi Shou. I tell my folks back at home that I'm a big shot, but I'm really just a delivery boy for a shop, here near the Himeda mountain ridge. I live in my simple apartment, with a simple life, driving these mountains every day. I'm absolutely nothing special... but all that changed after I got into an accident while on my delivery route. I didn't remember the details, but I awoke in the passenger-side seat of a taxi, driven by a beautiful girl! Her name was Michi, a girl with top-notch driving skills and a sexy body to boost. She claimed I was a genius racing navigator, and with me, she should be the best. Even if this wasn't true, I followed along with her case of mistaken identity. However, with my help, she became even better, and I've now started to attract the attention of other beautiful racer girls. Which one will I choose to guide to victory?!
