Reincarnation Coliseum, Vol. 3 (manga)

Fine Catastrophe--the last of Zayed's Four Kings and Mikagami's greatest opponent yet! With over a hundred skills at her disposal, she operates under complete secrecy, leaving not a single clue about the true nature of her abilities. Though all his previous victories came from careful planning and research, there's no room for scheming this time!

Will Mikagami somehow be able to improvise and win...?
