I don’t know.

A young ninja in a blue outfit stands before a crowd of identical figures in front of a building with a large, smiling face sign, then the scene cuts to him practicing taijutsu by punching wooden stumps in a snowy area, followed by a dark, blurry scene of a figure in a cave, then a menacing figure with horns standing in a cavern with a red, glowing sky, then a bright white figure in a dark environment, and finally a large, monstrous creature with a wide-open mouth and multiple eyes emerging from the ground.
