Just an anime.

A silver-haired anime girl's eye reflects a colorful galaxy, then the scene shifts to a pink-haired girl with long flowing hair standing in a snowy landscape under a large moon, followed by a dark-haired girl in a school uniform standing before a glowing crescent moon, then a close-up of her face, and finally a long-haired girl in a blue dress moving dynamically against a dark background with blue light effects.
