The monster on the road is me

Koda Okita is a high school student in modern-day Japan who isn t very popular. He suffers from narcolepsy and has to wear a watermelon-sized helmet to protect his head in case he falls. But Koda couldn t care less about his low social standing. He is content with taking long bike rides and hanging out in the convenience store parking lot with his school-dropout friend, Haru.
