Yowamushi Pedal

Synopsis

The rear slope race has finished, and Onoda has returned to Akiba to buy some more anime goods. There he runs into Naruko Shoukichi, a boy with a Kansai accent who is riding a bike. Naruko reveals he is originally from Osaka, but his family moved for work reasons, and he is in Osaka for the first time. Onoda buys some goods for Naruko's younger siblings, and the two become friends. When a passing car throws a cigarette butt at Onoda's bike, Naruko becomes infuriated, and he talks Onoda into pursuing this car with him on their bikes. Thanks to Miki, Onoda has gained a new front derailleur that might just provide him and Naruko the means to catch the car.
