Way Back When

Naruto Uzumaki holds a kunai to his forehead in a determined pose against a bright sky, then the scene cuts to a wide shot of a character standing on a tree branch overlooking a forested landscape, followed by a sequence of a character in a black tank top and pants performing a spinning kick on a smaller character in a red outfit, then a large wooden log is shown being driven into the ground with force, and finally a character with dark hair and a green and black outfit stands with hands on hips while two other characters stand in the background under an orange sky.
