BlazBlue is a popular series of fighting games developed by Arc System Works which currently includes four titles in the main series including: BlazBlue: Calamity Trigger, BlazBlue: Continuum Shift, BlazBlue: Chrono Phantasma, and BlazBlue: Central Fiction.
BlazBlue was also adapted into a popular TV anime in 2013 under the name of BlazBlue Alter Memory which is based on the first two games, Calamity Trigger and Continuum Shift. The series takes place in 2199 as a new era is about to dawn following a long period of magical warfare. However, there are rumours that the wanted criminal and SS-class rebel named Ragna the Bloodedge has been sighted in the 13th Hierarchical City of Kagutsuchi. Ragna currently has the largest ever bounty resting on his head for attempting to destroy the Novus Orbis Librarium and possesses a powerful form of Ars Magus in his prosthetic right arm known as the “Azure Grimoire” or “BlazBlue.” Suddenly a ragtag gang of fighters descend on Kagutsuchi hoping to claim the bounty and the Azure Grimoire for themselves.
