Aozora Floppy

Overview

Twelve years before the start of the story, Tokio Sorano was picked up in a coin locker at Shinjuku Station and raised by a group of vagrants. Undeterred by adversity, Tokio grew up to become a popular boy in the city, now ready to start middle school. His dutiful homeroom teacher, Masao Marui, tries to understand him, but Tokio is out of the norm in every way. As soon as he entered the school Tokio shows off his brilliant ball skill, which leads to his footwork being noticed by a classmate, Miyako Takano, a forward on the boys' soccer team!
