The Mana series, known in Japan as Seiken Densetsu, is a medieval-fantasy action role-playing game series from Square Enix, created by Koichi Ishii. The series began as a handheld side story to Square's flagship franchise Final Fantasy, though most Final Fantasy-inspired elements were subsequently dropped, starting with the second installment, Secret of Mana. It has since grown to include games of various genres within the fictional world of Mana, with recurring stories involving a world tree, its associated holy sword, and the fight against forces that would steal their power. Several character designs, creatures, and musical themes reappear frequently.
In 2003, the series comprised five games; since 2006, it has experienced a revival through the World of Mana campaign, with four new games released in the span of one year. As of 2008, the Mana series comprises eight console games and two mobile games, in addition to four manga and one novelization.
