The dude.
Bleh.
Wears kiahan robes, also known as samurai robes.
Matsuo sword, is Hyōrinmaru (literally "ice ring", idiomatically "full moon"). Hyōrinmaru's shikai command is translated in English as "sit upon the frosted heavens" or "reign over the frozen sky" sōten ni zase?). Hyōrinmaru is the strongest of all ice element sword in every dimension. Hyōrinmaru's spirit is a large, winged, Chinese dragon. Hyōrinmaru allows Matsuo to control water and ice. The slashes created by Hyōrinmaru gives off an immense amount of spirit power which overflows from the tip of the blade, creating a flow of ice vaguely shaped like Hyōrinmaru's dragon spirit. The dragon flies at opponents and instantly freezes anything it touches. The chain-blade also freezes anything Matsuo traps with it.
