The year is 1991 and 6th grader Yaguchi Haruo only has video games to live for. He's not popular in school and he's neither handsome, funny, nice nor even friendly. The only thing he has going for him is that he is good at video games. One day at the local arcade, he plays Oono Akira, a fellow classmate but who's popular, smart, pretty and a rich girl that absolutely destroys him at Street Fighter II. Not only does he lose to her 30 times in a row, he can’t beat her at any game. Haruo can’t seem to shake Akira off as she follows him from arcade to arcade everyday after school and beats him every time. As weird as it sounds, the odd couple begins a strange bond and friendship.

Now in his first year of high school, Haruo realizes his time playing the new Sega Saturn console at home have greatly diminished his arcade skills.

As Haruo pulls off Guile's super combo moves on the newly added Super Street Fighter II X machine, a familiar face returns to the local arcade scene.

With high school entrance exams coming up next year, Haruo fears his time playing fighting games at the arcade with Akira will soon come to an end.

Moemi has pushed Akira to excel her whole life, but all she cared about was arcade games. She still likes games, but she also likes Haruo.

With tours of historic landmarks over for the day, Haruo sneaks off alone to the city of Osaka to compete in the Super Street Fighter II X tournament.

The tournament begins with Haruo running on very little sleep. After he advances in his own match, he's dumbfounded to see the result of Akira's.

Stranded out late with Akira, Haruo asks his mother to help him find a place to stay. Hidaka visits Haruo's house to lend him her PlayStation console.
