Gangan (ガンガン, Gangan) is a manga imprint owned by Square Enix Holdings. It originated as a manga imprint for Enix before the company merged with Square to form Square Enix. It publishes manga in several anthologies aimed at different reader demographic groups in the Japanese market. Its anthologies are home to some popular Square Enix manga series which were adapted into anime series, like Fullmetal Alchemist, Moribito: Guardian of the Spirit, Nabari no Ou, Inu x Boku SS, The Case Study of Vanitas and Soul Eater. The comics are later collected in paperback volumes under brand names such as Gangan Comics (ガンガンコミックス, Gangan Komikkusu), Gangan Comics Joker (ガンガンコミックスJOKER, Gangan Komikkusu Jōkā) and Young Gangan Comics (ヤングガンガンコミックス, Yangu Gangan Komikkusu), which identify the anthology of serialisation. These paperback brand names are formed by omitting any gekkan (月刊, monthly publication) or shōnen (少年, boy) in the magazine name and inserting Comics (コミックス, Komikkusu) directly after the word Gangan.
