In this world... There are many horrible things that you do not want to see.
~ Fujitora regarding his blindness
Fujitora is the alias adopted by Issho, one of the three Marine admirals, replacing Aokiji sometime during the two-year separation of the Straw Hat Pirates. He is a secondary antagonist in the Dressrosa arc of the One Piece anime/manga, as well as an immensely powerful and blind swordsmen with an as-of-yet undisclosed Devil Fruit ability. He was motivated to join Marines in order to see many things come to fruition, including his desire to see a permanent end to the World Government's Shichibukai system.
Issho is a very calm individual and has been shown to keep cool even under difficult circumstances. He is also extremely trusting of strangers to the point where he was easily swindled by gamblers in a game of roulette. After being told by Luffy that the gamblers had been lying about Issho's losses, he retaliated mercilessly against them. Despite the collateral damage he inflicts, Issho takes responsibility for this and even compensated the shop owner after the destruction he caused in assaulting the swindlers.
