Kensei Muguruma

Kensei Muguruma (六車 拳西, Muguruma Kensei) is the former captain of the 9th Division. Kensei appears to be a young man with short, light-gray hair and several piercings. He also has a tattoo of the number 69 on his stomach, which was the inspiration for the one Shūhei Hisagi has on his cheek after saving him when he was younger. In comparison with his fellow Visoreds, Kensei is a much more serious character. He has a short temper and is easily irritated, particularly by Mashiro. Kensei's zanpakutō is named Tachikaze (断地風, Tachikaze lit. earth-severing wind). His shikai shrinks it down into the form of a survival/combat knife. While in this form, Kensei demonstrates the ability to charge and fire spiritual energy from the blade. His hollow form looks humanoid with cylindrical structures sprouting from his back and shoulders. His mask looks similar to a hockey mask, but is squared off with six eyes and extends around the back of his head. He is voiced by Tomokazu Sugita.
