When at last a wielder who can withstand Muramasa's demonic power appears on the scene... it is a baby, Nobumitsu! Nobumitsu, who was abandoned by his father Nobuyaku because of his kindness and weakness, wants to become strong and be recognized by his father, so he and Muramasa resonate, and the strongest of the two are born!　But what happens when Nobumitsu and Muramasa are pursued by Nobumitsu and Muramasa?　This is a buddy-battle action of "Youtou x BABY"!
