Kenji

Kenji was an assassin during 2161.

Background
Hired by Gizmo to kill Killian Darkwater in Junktown, Kenji is just known as an assasin, that was killed by the Vault Dweller. It is unsure if this is canon or not.

Interactions with the player character
Kenji comes into his store right after the initial conversation with Killian, takes out a hunting rifle and starts shooting. His only purpose is to die and start the Killian/Gizmo struggle questline, and to give the ability to get Tycho, the desert ranger.
