The year is 1991, and arcade video games are the latest craze. Becoming a professional gamer is a far-fetched dream in an industry that has yet to spread its influence. Yet, that is the path sixth-grader Haruo Yaguchi wants to pursue. His aptitude for video games has earned him respect in local arcades and bestowed him with confidence and pride, both of which are shattered when fellow classmate Akira Oono easily defeats him in Street Fighter 2.

But Haruo had never cared about these things as, despite his multiple shortcomings as a person, his supremacy in video games was, in his mind, undisputed.
