Ninja Master M is an eccentric player who dresses and acts like a ninja. When the Card Capital Shop Tournament appears, he decides to take part. He uses the ninja moves during a fight to confuse an opponent. He meets Aichi Sendou, who deduces that he is actually his teacher Mark Whiting, but he denies that claim (even though it's true).
Ninja Master M plays a Nubatama and Kagero mixed deck, focusing on having card advantage over the opponent (i.e. forcing the opponent to discard cards from his/her hand). His ace is Stealth Dragon, Voidmaster.
