Dennis is an exchange student from the LDS Broadway branch. He is a well-rounded and charismatic type of character and has a sense of humor, yet can also be serious at times. As an admirer of Yusho Sakaki he runs a Deck that seems to mirror his and Duels as a Dueltainer, thus he is often flashy and enjoys performing acrobatics. When excited he seems to be rather air-headed and tends to forget about anything else at the moment, as seen when he wanted to talk to Yuya since he is the son of Yusho and enjoyed his Dueling, only to be interrupted in the still ongoing Duel by the Ryozanpaku School students' offensive, forcing him to block their attempts at damage while showing comical frustration at their interference.
