Gangan is a manga brand owned by Square Enix. It was first created by Enix before the company joined with Square to become Square Enix. Gangan publishes manga in collections that target different groups of readers in Japan. These collections include popular manga series from Square Enix that were later turned into anime shows, such as 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 printed in paperback books with names like Gangan Comics, Gangan Comics Joker, and Young Gangan Comics. These names are made by removing words like "monthly" or "boy" from the original magazine titles and adding the word "Comics" after "Gangan."
