Ninja Master M is an eccentric player who dresses and acts like a ninja. His true identity is the Hitsue Middle School teacher Mark Whiting. He takes part in the first Card Capital Shop Tournament in the anime, where he declares his plays as ninja techniques during fights, which confuses his opponents. During this tournament he meets several of his students, including Aichi Sendou, who deduces that he is actually their teacher, a claim which he hurriedly denies. Following the aforementioned shop tournament, he anonymously gives Katsumi Morikawa the Ninja Master M costume, and foregoes entering any further tournaments at Card Capital.

Mark Whiting as Ninja Master has not reappeared until Cardfight!! Vanguard: Season 3. During the mass Reversing of Miyaji Academy, he suddenly appears before Kamui Katsuragi and a Reversed Nagisa Daimonji during an open house at the middle school under the new alias "Ninja Master Neo", with the main difference being that his helmet now has a badge on its crest with the word "Neo" etched on it. He then challenges Reversed Nagisa, in order to allow Kamui to rescue Emi Sendou and Mai Tobita. Unusually, he demonstrates that he is aware of the Reverse phenomenon and its effects, despite never having it explained to him or ever having been Reversed himself.


First Season

Ninja Master M plays a Nubatama and Kagero mixed deck, focusing on gaining card advantage over the opponent by forcing the opponent to discard cards from his/her hand. His ace is Stealth Dragon, Voidmaster.


Third Season

In Season 3, he now plays a complete Nubatama deck, using recently released support from Booster Set 13: Catastrophic Outbreak. Along with his previous strategy of discarding cards fom his opponent's hand, he now also focuses on binding the opponent's hand and rear-guards, limiting their options while he goes in for the finishing blow.
