Taimanin Asagi Battle Arena (対魔忍アサギ~決戦アリーナ~, Taimanin Asagi: Kessen Arena) is a battle card game developed by black lilith and published by DMM. It encompasses a non-canon story detailing events between the anti-demon ninjas, the united states, and the demons. Styled in the same way as the original taimanin asagi game releases, battle arena is described as being more of an all-star game rather than a fully fledged sequel to taimanin asagi 2.
