Yoshiro Kazuki (森一樹), known by the username Shirozuki (白心緒) but preferring the shorthand Shiro (白), was one of the 10,000 players trapped in «Sword Art Online». He was a founding member of a Clearer guild called «Brightscale».


Yoshiro was the tallest initial member of «Brightscale»,[Notes 1] has brown-coloured eyes,[1] and sports unusually long red-coloured hair which is usually styled in a tight braid that rests on his right-shoulder.[2] As a Tank he predominately wore heavy armor.[3]

Suit of the Exile

Yoshiro's first unique set of armor was classified as «Heavy Metal Armor» as far as the system was concerned, but the «Suit of the Exile» was actually constructed from «bones» and various leather drops from the 2nd Floor.[4] It was lighter than contemporary metal armors and was a form-fitting design allowing for ease of movement despite its armor-class, with a skeletal appearance. The helmet was the most visually unique piece of the entire set: it featured two forward-pointing horns and a T-visor slit.[5] By the time his team completed the first chapter of the «Elf War» campaign quest Yoshiro had adopted a short cape that extended to the base of his shoulder-blades and fell about his upper-chest, which he received as a drop from the «Fallen Elf Commander».[1]


Kenji described Yoshiro as a dependable guy despite only knowing him for a few hours at the time. He also suspected that Yoshiro had younger sisters based on how easily he interacted with Momoko and Akiye.[2] Not only could he calm them down when they where scared but he was also fit to keep them entertained by telling them stories of their various adventures.[6] In everyday interactions Yoshiro is a disciplined man who rarely bows to pressure, and works exceptionally well in raid-settings with Kusaka.[7] He is tolerant of others, shows genuine concern for other peoples well-fare, and doesn't hesitate to interpose himself between his allies and dangerous opponents.[1]

Yoshiro is a sword'n'board Tank.[3] In normal situations from the 3rd Floor onward this meant he was Kenji's damage sponge, but in raid-party settings he and Kusaka showed the necessary discipline to pull off flawless aggro switches for potion rotation.[7] He initially had Medium Metal Armor but switched to Heavy Metal Armor when Kusaka offered his old set of «Iron Armor» to him.[2] On the battlefield he maintains a cool head and is capable of quickly formulating unorthodox strategies in the heat of the moment.[6] He also fights to a very high standard and possesses a high level of player skill.[1]
