Crayon Shin-chan: Chou Arashi wo Yobu Kinpoko no Yuusha

A comedic fantasy centered on a battle against extraterrestrial invaders. A dark realm, ruled by Dark, seeks to conquer the human world. According to legend, three artifacts and a chosen hero exist in this dark world. Dark seizes one of the treasures, the copper bell, while the other two—a golden spear and a silver shield—are sent to the human world. Shinnosuke accidentally triggers a portal between the two worlds by falling into Dark's trap but is chosen by the golden spear as the hero. With the aid of Mata Tami, a girl from the dark world, the Nohara family transforms into different objects and engages in combat against Dark.
