Wakaba has finally earned his driver's license, and he has exactly one thing planned with it: a date with his girlfriend Clutch. To save money, he chose the cheapest driving school available.

When a staff member with an unusual laugh and a visible tail arrives to escort him personally, Wakaba says goodbye to Clutch and follows — into something considerably stranger than driver training.
