From the anime.

A young woman with brown hair looks upward with a bright light behind her, followed by a rapid transition through a glowing tunnel, a sunlit rural landscape, and a scene of the same woman standing by a river, then a close-up of a different woman with blonde hair in a traditional outfit, and finally a bright light effect in a dark environment. The sequence depicts a journey or transformation involving two female characters in various settings, including a rural landscape, a riverside, and a formal event.
