Pokemon-Hello, from The Heights: Ghost of Mount Hideaway

[ THIS IS A FICTIONAL SERIES WITH FANTASY ELEMENTS. PLEASE DO NOT ATTEMPT ANYTHING DESCRIBED. DRIVE SAFELY AND RESPONSIBLY. THANK YOU! :) ]

There are some people in the Pokemon world who battle without Pokemon, whether for competitive sport or for recreational fun. Some of these people battle on the streets in their cars, regardless of legality. The two most popular forms of street motor sports is touge (mountain racing) and wangan (highway racing).

Yutaro Watanabe (渡辺佑太朗) is an ordinary delivery boy for his dad's mochi business. Every other night, he drives up Mount Hideaway to the hotel at the top, and then back down. He has to be quick with his deliveries so the mochi doesn't go too warm, so he's built an unconventional way of driving fast.
His best friend, Akua Enatsu (江夏青水) is an utaite singer, a trainer, and a very big car enthusiast. She's tried to get Yutaro into cars before, but he's constantly told her he knows what he need to know about cars-they take you places and they're well-engineered.
Little do the two friends know what kind of 'secondary world' they'll suddenly immerse themselves in.
