Kurisu

Kurisu is a tribal from the Primitive Tribe in 2241, who in 2253 became a leader of the Blackfoot tribe.

Background
Kurisu is the sister of Sulik, a tribal warrior. Kurisu is a young tribal girl kidnapped by slavers. Although Sulik's quest was to find her, he never did.

She somehow appeared many years later somewhere in the Southwest and became the leader of the Blackfoot tribe.

Appearances
Kurisu was first mentioned in Fallout 2, but was not given a name. She was initially meant to be found in the game, but this quest was eventually unfinished and Kurisu was cut from the final version.

She also was to appear in Black Isle's cancelled Fallout 3 project (Van Buren) as a joinable ally. Her name was revealed in the Van Buren leaks (it is a joke concerning Avellone's first name, her name being 'Chris' with Japanese pronunciation).
