A main character in Cardfight!! Vanguard: Shinemon, in which he is in his third year at high school. He initially appears as a minor character in the Cardfight!! Vanguard (V Series Anime) as a history teacher at Hitsue Middle School.

Mark is not originally from Japan, but is infatuated with the country's history and culture. He moved to Japan as a child for unknown reasons, and uses his love of Japan in his profession as a history teacher. His eccentricity and quirkiness is apparent when he teaches, and he uses a Japanese history-based trading card game to teach his lessons.

He is best friends with Shinemon Nitta, and uses his "18 years of history as a ninja" to help his friends. He is apparently a maniac for the Sengoku period of Japan. He has a ninja costume which he uses for cosplay purposes, and even has smoke bombs. While wearing his cosplay outfit, he becomes "Ninja Master", and talks in an old fashioned way, ending his sentences with "Degozaru" ("verily" in the English dub and Japanese sub).

The protagonist of this story, Sendo Aichi, is a timid boy in his third year of middle school. He had been living his life looking backward rather than forward, trying not to stand out. However, he had one thing that kept him going - the "Blaster Blade," a card from a card game that was given to him when he was little. That card is the reason why he begins to engage in Card Fights, something that changes his life drastically. 
The name of the card game is "Vanguard." The game takes place in a different planet called "Cray," and due to a never before seen play system, it becomes popular throughout the world. 
Aichi, immediately attracted by Vanguard, meets friends such as Tokura Misaki and Katsuragi Kamui, along with other rivals. Through friendly rivalry with them, Aichi begins to enjoy a fulfilling life. Aichi, however, has a goal: to once again battle with a Vanguard Fighter by the name of Kai Toshiki. Kai Toshiki is an aloof and cold-hearted high schooler who has outstanding abilities in the world of Vanguard. He is also the reason why Aichi started playing the game. For him, Toshiki is the person who saved him from his boring life and introduced him to Vanguard. In order to get better at Vanguard, Aichi puts his soul into it every day. He wishes that someday, he'll be able to battle Toshiki and have him recognize his worth.
