This is a list of Soul Reaper characters featured in the anime and manga series Bleach, created by Tite Kubo. Soul Reapers are a fictional race of spirits who govern the flow of souls between the human world and the afterlife.
The series follows how Ichigo Kurosaki becomes the substitute of the Soul Reaper Rukia Kuchiki. Since then he assumes her duties to protect souls to make them rest in peace as well as to fight against creatures called hollow, which are souls that cannot rest. However, as the series, Rukia is arrested by the Soul Reapers' organization, Soul Society, for giving her powers to Ichigo and prepares to execute her. Ichigo and his friends go to save her and are forced to fight against all the Soul Reapers' divisions. However the 5th division captain, Sōsuke Aizen betrays Soul Society and starts a plan to destroy it.
Mayuri Kurotsuchi is the captain of the 12th Division. His unusual appearance is due to heavy make-up. He is cruel and callous towards everyone, including his daughter/creation/lieutenant Nemu Kurotsuchi. He is the "mad scientist" of the Soul Society and is in charge of the Shinigami Research Institute.
He is a brilliant opponent usually studying his foes in detail. However in a battle with Uryū Ishida, the last quincy, he is forced to turn himself into a liquid to escape. During that battle Mayuri treats Nemu with such cruelty that Ishida calls on him to stop.
Despite the cruelty Mayuri is a great inventor, strategist, body modification expert, and chemist.
