Kingsglaive: Final Fantasy XV is a 2016 Japanese animated fantasy film that serves as a companion piece to the video game Final Fantasy XV.
Directed by Takeshi Nozue and written by Takashi Hasegawa, the film is set in the same universe as the game and runs parallel to its opening events.
The story focuses on King Regis Lucis Caelum CXIII, the father of the game's protagonist Noctis. Regis commands the elite Kingsglaive soldiers, who share his magical powers to defend the kingdom of Lucis and its Crystal from the invading empire of Niflheim. When Regis accepts a peace treaty that requires his son to marry Lady Lunafreya Nox Fleuret, it turns out to be a ruse for Niflheim to invade. Kingsglaive soldier Nyx Ulric gets caught up in the battle to secure Lucis's future.
The film features an English voice cast including Aaron Paul, Lena Headey, and Sean Bean. It was released theatrically in Japan in July 2016 and received a limited release in North America the following August. Digital and physical home video versions were released in October 2016, bundled with certain editions of Final Fantasy XV.
Reviews were mixed, with praise for the visuals and action sequences but criticism of the convoluted plot and lack of character development. The film grossed over $6.5 million worldwide from its limited theatrical run.
