The narrative centers on a young man named Tsubame, who leads a double life as a high school student by day and a master thief known as the "Rainbow Parakeet" by night. Tsubame's alter ego is inspired by his late father, a legendary thief who was known for his flamboyant heists and moral code. Tsubame adopts his father's legacy, targeting corrupt individuals and organizations, stealing not for personal gain but to expose their crimes and redistribute wealth to those in need.

The story unfolds in a modern urban setting, where Tsubame's exploits as the Rainbow Parakeet draw the attention of both law enforcement and rival criminals. His primary adversary is Detective Kurosaki, a determined investigator who is both fascinated and frustrated by the thief's elusive nature. Kurosaki's pursuit of Tsubame is driven by a personal vendetta, as he believes the Rainbow Parakeet is responsible for a past tragedy. This dynamic creates a tense cat-and-mouse game, with Tsubame constantly outsmarting his pursuers while grappling with the moral complexities of his actions.

Tsubame's team includes a small group of allies who assist him in his heists.

Their camaraderie and shared mission add depth to the narrative, highlighting themes of loyalty and justice.

As the series progresses, Tsubame's dual life becomes increasingly precarious.
