The official Twitter account for the Celestial Method television anime series announced on Saturday that the previously announced new episode for the anime will debut on October 11. The wording used indicates the episode will screen in theaters, but the Twitter account has not yet confirmed that officially. The account stated it will reveal more details "soon."

The episode is adding the new character Carol, voiced by Marika Kōno .

Celestial Method was an original fantasy work focusing on one girl's return to her hometown, after the death of her mother and resulting reunion with her childhood friends. One of those friends, though, she does not remember. That friend is Noel and she has some kind of connection to the UFO that hangs over the entire city.

Masayuki Sakoi directed the television series that premiered in October 2014 at the new Studio 3Hz off of an original concept and script by Naoki Hisaya ( Kanon ). The illustrator circle QP:flapper ( MM! ) designed the characters. Crunchyroll streamed the series as it aired, and Sentai Filmworks licensed the anime for North America.
