Ninja Master's: Haoh-Ninpo-Cho (ニンジャマスターズ ～覇王忍法帳～, Ninja Masutāzu ~Haō Ninpō Chō~, "Ninja Master's Scrolls of the Supreme Ninja Arts"), most known as just Ninja Master's, is a ninja-themed competitive fighting game produced by ADK originally released in 1996 for the Neo Geo arcade and home platform. It was later featured in the 2008 compilation ADK Damashii for the PlayStation 2. It was the sixth and final fighting game produced by ADK, following the four games in the World Heroes series and Aggressors of Dark Kombat.
Ninja Master's 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.
Ninja Master's also has a super meter similar to The King of Fighters and other fighting game series.
Like various ADK games, SNK Playmore also revived characters from this game in their last releases. In this case, Sasuke (the main character of this game) appears as an SNK character card in SNK vs. Capcom: Card Fighters DS.
