Attack on Tomorrow

 was an anime series aired in 1977 in Japan. There were 23 episodes aired at 25 minutes each.
It is often mistakenly believed to be a spinoff of the earlier and more popular, series "Attack No. 1" (1969-1971), due in part to the involvement of several staffers (including directors Kurokawa and Okabe and writer Yamazaki) who had worked on the prior series. It is not an official spinoff, and it is more likely to have been inspired by the popularity of "Attack No. 1".
It is also known in Europe as "Smash" (French) and "Mimì e le ragazze della pallavolo" (Italian).
Original Story.
The story is about Mimi Hijiiri, a student with just one school year remaining, who decides to revitalize a volleyball team low on morale from the death of one of its team members from an accident.
Concept.
The series was strictly created as a tribute to the gold medal the Japanese women's volleyball team earned in the 1976 Olympics.
Reaction.
While the show would eventually aired in the European market in the 1980s in countries such as France and Italy, the plot and concept was too similar to its predecessor Attack No. 1 and ratings were low. The show ceased production after only 23 episodes.
