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.
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.
Completely oblivious, Haruo watches in awe as Koharu and Akira duke it out on Virtua Fighter 2. At the game center, Koharu can't help but taunt him.
Representing Shibuya, Haruo faces players from Mizonokuchi, including Koharu, in a 10-person Street Fighter Zero 2 arcade battle.
When Makoto presses him about his feelings towards Akira and Koharu, Haruo flees. Out on the street, he's abducted by a group of men in suits.
Koharu challenges Akira to a Super Street Fighter II X match. For her, there's more riding on the game than which of them is the arcade champion.
Haruo realizes how much Akira means to him and visits Miyao to confirm it. To prove himself, he invites Akira to join him at a tournament in Osaka.
Akira keeps her impending move to Los Angeles a secret. In Osaka, she and Haruo spend their time on the eve of the tournament in various arcades.
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.
Akira and Haruo face off in the tournament's final round. Months later, Haruo hasn't recovered and Akira's departure nears. Then Makoto comes to visit.
