Attack on Tomorrow!

is a Japanese sports anime series produced by Nippon Animation as a tribute to the gold medal the Japanese women's volleyball team earned in the 1976 Olympics. It aired in Japan's Fuji TV network from April 4 to September 5, 1977.

The series is most likely to have been inspired by the popularity of the earlier volleyball manga, Attack No. 1, to which fans often mistakenly believed to be a spin-off of the prior series when several of its staff (including directors Kurokawa and Okabe and writer Yamazaki) worked on the current series.

Plot
Mimi Hijiiri, a high school student in her last senior year, is determined to revitalize her volleyball team after one of its team members died from an accident.
