Isshou, better known by his alias Fujitora, is an admiral in the Marines. Once the military chief of the former Aoi Kingdom, he was conscripted through a World Military Draft during the two-year timeskip, being appointed to fill one of the Admiral vacancies caused by Kuzan's resignation and Sakazuki's promotion alongside his co-worker Ryokugyu. A proponent of "Moral Justice", he notably spearheaded a campaign to abolish the Seven Warlords of the Sea system. Fujitora was first mentioned by Sakazuki when the latter was first discussing plans to deal with Monkey D. Luffy and Trafalgar Law. His primary goal is to protect people, telling a subordinate that it is more important to take into account the number of lives to protect rather than the number of enemies against them. He takes care to never put innocent civilians in harm's way during conflict and will try to avoid causing collateral damage with his attacks; when he does inflict such damage he makes sure to compensate the owner of the involved property. In his devil fruit's name, Zushi Zushi is a Japanese onomatopoeia that describes a "thump" or "thud" sound, representing the footfall of something heavy, e.g. stomps of sumo wrestlers. His blindness is a result of him intentionally inflicting damage on his eyes out of sorrow for all the evil he had seen
