Shin-chan movies are supposed to be dumb fun, so when one decides to actually care about the people dying in a war, it catches you off guard. The comedy is still there, but it's compressed into these sharp moments that make the rest of the film, the 2D animation of soldiers moving in formation, a princess trying to hold her city together, a five-year-old understanding bravery for the first time, hit with a weight Shin-chan has no business carrying. By the end you're not laughing at Shin-chan. You're watching him matter.

When a time warp accidentally carries the Nohara family back to 1574, in the closing years of Japan's Sengoku Era, Shin-chan finds himself caught between two worlds. The family lands in the Province of Musashi, where Lord Kasuga rules and a war threatens his daughter's city. Shin-chan and his family throw themselves into the fighting to help protect it. Alongside the conflict runs a doomed romance between Princess Ren Kasuga and Matabei Ijiri, a samurai who serves her father. The film pairs the franchise's comedy with a historical drama set in feudal Japan.
