Dragon

Two anime characters stand in a grassy field under a blue sky, then the scene cuts to a close-up of two characters fighting, one with brown hair and a red bow, the other with dark hair and a pink dress, their hands clasped as if in a struggle, followed by a rapid sequence of blurred motion, a bright flash, a silhouette of a figure with a curved blade against a red and green background, and finally a dark, indistinct scene with floating particles.
