Attacker You!(1984)

Attacker You! follows You Hazuki, an ambitious 13-year-old who moves to Tokyo from Osaka to live with her cameraman father after he returns from Peru. Raised without her mother, You throws herself into volleyball with fierce determination, driven partly by curiosity about Kyushi Tajima, a glamorous blonde commentator she sees on television. Her younger brother Sunny shadows her constantly, while her father's mysterious anger whenever Tajima's name comes up hints at a hidden past. As You pursues her dreams on the court, she begins uncovering the complicated connections between her family and the woman who captivates her. This anime series blends coming-of-age drama with sports action, capturing the intensity of junior high life and the bonds that hold families together despite their secrets.
