Crayon Shin-chan Movie 13: Densetsu wo Yobu Buriburi 3-pun Dai Shingeki

A visitor from the future named Miraiman appears before the Nohara family with a bizarre request. Distortions in space-time are producing giant monsters in a world exactly three minutes ahead of their own, and unless each creature is defeated within that short window, the destruction will spill into the present.

Hiroshi and Misae discover that entering the future also lets them transform into powerful heroes, and monster fighting quickly becomes more exciting to them than ordinary family responsibilities. But when an enemy appears that cannot be beaten in three minutes, the game turns into a genuine crisis and Shinnosuke must step forward before both worlds are destroyed.
