Ninja Master's: Haō Ninpō Chō (ニンジャマスターズ ～覇王忍法帳～ roughly translated as "Ninja Master's Scrolls of the Supreme Ninja Arts") is a ninja-themed competitive fighting game produced by ADK originally released in 1996 for the Neo Geo arcade and home platform.
Ninja Master's was the sixth and final fighting game produced by ADK, following the four games in the World Heroes series and Aggressors of Dark Kombat. It was later featured in the 2008 compilation ADK Tamashii for the PlayStation 2.
Ninja Masters follows the conventions of many previous 2D fighting games released for the Neo-Geo. The player must defeat their opponent in combat in a series of best-two-out-of-three matches. Characters can change between using the character's weapon or fight hand-to-hand during the middle of combat. Like The King of Fighters series, Ninja Master's features a super meter.
