Giri D. Mustash (義理の口ひげ, Girie D. Mustashu) or otherwise known as his alias as the Big Stache (ビッグ口ひげ, Ogatashu?), was a world renowned fashion designer whose own fame had rivaled that of Ozanam Serpiente, before he himself had became a pirate. However, Giri had faked his own death by pretending he had committed suicide and thus becoming a bandit. He now is the fifth strongest member of the Sichiyozoku and also acts its treasurer and itself smarts of the group.
