The blurb is WRONG. It is describing the plot of Goshogun: Time Etranger from 1985 (instead of 86) (https://www.anisearch.com/anime/2734,goshogun-time-etranger). Unfortunately that is another Movie!
Unfortunately even wikipedia does not have a plot summary for this movie (although there is a wikipedia page that contains more or less no info). It is about some guy travelling through time in a schoolbus but only in the past
