Dajimu

is a member of the disbanded faction of Konohagakure's Anbu: Root.

Background
Dajimu, like most members of the group, was likely trained to lose emotions in order to better accomplish missions. As Root members each use a codename, it is unknown what Dajimu's real name is, if Dajimu even has one.

Personality
Even though the organisation has been officially disbanded, Dajimu remains loyal to its head, Danzō Shimura.

Five Kage Summit
Dajimu and Tera had both been secretly assigned by Danzō to assassinate Anko Mitarashi, but due to the village's situation at that time, their mission was postponed in preference of finding Kabuto Yakushi before she did.
