Hishakaku has a very long spiked hair, thin dark eyebrows and three crystal-like marks on his forehead. He wears traditional Japanese clothes, and always holds a fan, which he uses as a D-Pad. He also wears a mouth-like mask covering his nose and mouth.
Hishakaku uses a "Line Monster" Deck, whose effects are based on a card's position on the field. All of his card's names, designs and effects are based on Shogi, and use terms of the game instead of terms of Duel Monsters. Check the cards' Trivia pages for more information.
