Otokotsu, a different character from the main character, Torajo, is a shonen manga protagonist with old-fashioned friendship, hard work, and growth. And since this film is an original story as a prequel, it can be enjoyed even if you have not seen the TV anime, and the action is so cool that it is a representative theatrical animation of the 2020s.

Kougami, who did not appear in the second season of the TV series, made an appearance. Since he disappeared at the end of the first season, and that was the end of it, it was good to see him say goodbye to his friends. The farewell to Ginoza is especially memorable.
