Umio is a timid teenager who has just begun working part-time at a manga shop right in the heart of the city. Yet his daily routine is far from as dazzling as the neon glow that lights up the streets. Umio's closest companions are his fellow employees, each a distinct personality, and while they are kind-hearted, they carry their own eccentricities. They form a close-knit circle, exchange playful nicknames, and spend weekends indoors, shielded from the extravagant bustle outside, while the city hums with endless neon brightly dreams everywhere.
