The archetype is based on a commonly-served kind of sushi called gunkan-maki (軍艦巻, literally "battleship-roll"), in which a ball of rice is wrapped around with seaweed and topped with a serving of seafood or vegetable. The name of the archetype itself is wordplay, using the characters「軍貫」instead of 「軍艦」. To keep in line with the popular name of the archetype prior to its localization, all "Gunkan" cards in the TCG also contain the word "Suship".
