Crayon Shin-chan Movie 10: Arashi wo Yobu Appare! Sengoku Daikassen

After Shinnosuke begins having strange dreams, the Nohara family discovers a hidden connection to Japan's Sengoku era and is suddenly transported back to the year 1574. Their modern habits collide immediately with a world of feudal lords, samurai armies, and battles where mistakes carry very real consequences.

There Shinnosuke befriends the warrior Matabei Ijiri and learns of the feelings between Matabei and Princess Ren Kasuga, a love constrained by duty and social position. When war threatens Kasuga's domain, the Noharas become entangled in a historical conflict far larger than themselves, and Shinnosuke's presence begins changing lives whose futures once seemed fixed.
