Mayuri Kurotsuchi is the captain of the 12th division and is the second generation president of the Shinigami Research and Development Institute. His Lieutenant is Nemu Kurotsuchi


Mayuri has a very peculiar appearance, partially becuase he paints his face every morning. Mayuri's appearance noteably changed halfway through the series.

At the begining of the Soul Society Arc, he wore a white hat with golden ear and chin gear. His teeth were white, and his eyes are golden color. He wears a baggy white haori with a large purple scarf around his neck, and has short fingernails, with the exception of one extraordinarily long one. During the Arrancar arc his apperence changes. He no longer wears the hat, his blue hair has grown long, and his new headgear resembles that of an Egyptian pharaoh


Mayuri is a very sadistic and cruel person. He is well known for the abuse of his subordiantes, especially his created daughter and Lieutenant, Nemu Kurotsuchi. However, he is also very intelligent, and can easily decieve most people, including Uryu Ishida and Szayel Aporro Grantz, both of whom he fought.
