Children of Indigo

A blonde-haired man in a red shirt and beige jacket performs a high kick in a traditional Japanese room, then appears in a different outfit wielding a curved blade in a confrontation with another man in a blue suit, both in the same room; the scene shifts to a large white dragon with a yellow eye and a long, coiled body, first shown in close-up, then in a wide shot where the man in the blue suit leaps toward it in a large arena with a starry sky, and finally the dragon is seen in a natural setting with waterfalls.
