The Undertaker Squad

The ANBU Squad 24 is a special division in the Kirigakure ANBU Hunter-nin. They could be seen wearing standard armoured ANBU uniform or, in some instances (such as Ishidate and Mazaki), a blue kimono with a striped, turtle-necked undershirt. They may also wear a mask with thin slitted eye-hole and a wavy design in place of the mouth, and their village symbol on the forehead. They kill their target, taking the head as proof, and then completely dispose of the body by using various methods, such as cremation or the summoning of wild carrion crows to devour the corpse. This is done in order to make sure the village secrets which a ninja's body holds — such as chakra types, herbs eaten, ninjutsu, special medicine, and kekkei genkai — will not be revealed to outsiders.

The squad are supposed to destroy the corpse at the very spot the body is lying; it is not to be moved after it is dead, and only the head is taken back to prove that the missing-nin is in fact dead. As a requirement, they must possess a thorough and intimate knowledge of human anatomy. Due to their reputation for utterly and completely obliterating the remains of their targets, they are code-named "The Undertaker Squad" (当る隊, Atarutai).
