Attacker You! is the story of ambitious and energetic 13-year-old junior high schoolgirl You Hazuki (variously known as "Mila," "Jeanne" or "Juana" in Western dubbed versions of the anime), who moves to Tokyo from Osaka to live with her father Toshihiko, a cameraman recently returned from Peru, and attend school. You's mother is not in the picture, having left when You was very young. Also living with You and her father is her younger brother Sunny, who is very attached to his older sister and tends to follow her everywhere she goes, including to school and to her volleyball matches. You is also curious about Kyushi Tajima, the pretty blonde woman whom she sees covering volleyball games on television, and about why her father becomes very angry whenever You mentions her. You is passionate about volleyball and dreams of one day being a part of Japan's national women's volleyball team in the 1988 Seoul Olympics. She joins her school's girls' volleyball team and quickly becomes one of the top players, although her coach (who is also her homeroom teacher) is brutal and literally slaps his players around when they don't live up to his expectations. You begins a tumultuous friendship with former school volleyball champ and former arch-rival Nami Hayase (French name: "Peggy"), which comes to a head when the two girls join opposing professional teams. She also develops a crush on So Takiki, the captain of the Hikawa boys' volleyball team (known as "Shiro," "Serge" or "Sergio" in various Western versions), and puts as much effort into trying to win his heart as she does into her game.

The first 33 episodes are a summary of the previous series. In the first new episodes a new character, Shingo Aoi, (playing in Italy) is introduced. After that the world cup begins, this time with extraordinary, new countries like Sweden, Thailand or Uzbekistan. Unfortunately the Anime ends in the middle of the world cup after the match Japan-Uzbekistan.

Shin CT takes place at the U-16 word cup in France. After some friendly matches in Germany, Japan defeats one opponent after another and finally reaches the final round against Germany. After hard matches against Italian and French top players, the German team seems to be even more supreme. The giant goal keeper Moeller, the all round ace Kalz and Europe's best player and forward Schneider offer the Japanese team an extremely hard match.

Takumi Fujiwara finally joins Ryousuke and Keisuke Takahashi to create "Project D." Their goal is twofold: Ryousuke wants to develop his "High-Speed Street Racing Theory," while Keisuke and Takumi aim at improving their driving skills by facing powerful opponents on dangerous roads. The idea of Project D is to challenge street racing teams from other prefectures to improve both their uphill and downhill records. In order to attract the attention of the best racing teams, Ryousuke creates a dedicated website to announce the future battles of Project D and post the team's results. The fourth season of Initial D details the hardships and successes of the members of Project D as they try to become the best street racing team outside of Gunma Prefecture.
