Burapa: The Black Parade

A high school student discovers an old, unused tram car and considers it a good spot for a secret hideout. He meets Fujino, a lively person who initiates a contest for control of the location. The contest takes the form of an imaginative, public game that surprises the student with its energy and creativity. Though initially skeptical, he finds the experience more thrilling than his usual video game sessions. The two eventually become friends and start exploring together, using the tram car, which they rename the "Black Parade," as their base for adventures.
