Haruo Yaguchi, a sixth-grader, lives solely through video games in 1991. He is not well-liked at school, nor is he attractive, humorous, or even amiable. He only has his skill with video games to his advantage. He runs into Akira Oono, a classmate who is not only well-liked, intelligent, gorgeous, and wealthy, but who is also viciously crushing him in Street Fighter II, one day at the neighborhood arcade. She not only defeats him here 30 times in a row, but she also wins every other match. Even worse, she follows him from arcade to arcade every day after school, so he is unable to get rid of her. As a result, this mismatched pair eventually develops a peculiar friendship over time.
