Yes. On articles, only images from official sources may be used.

This includes the Light Novel, Anime, Mangas, Web Novel, and promotional art for any of the mentioned sources (official magazine promos, and such).If there's doubt about what you can use, it's best to consult regular editors, for a second opinion.
