Plan A Third Episode
Orion is the ninth Japanese single released by Apink. It was released November 8, 2017 with "Orion" serving as the promotional track.
It was released in nine versions: a limited CD+DVD+GOODS edition (A) that comes with a 16-page booklet, 1 candle glass with Apink logo and 6 aromatherapy candles, a limited CD+DVD edition (B) that comes with a 12-page booklet, six limited CD editions that come with one of six picture labels (C), and a regular CD edition. Each edition comes with a trading card.
The contract with the agency that Apink was associated with in Japan expired so the single was released for the disbandment of "Panda Japan", Apink's official Japan fanclub.
