One of the nineteen leaders of the Hashshashin sect and the 19th who took the name of Hassan-i-Sabah and the mantle of Old man of the Mountain.

This particular individual suffered from Multiple Personality Disorder which he utilized to compartmentalize his abilities. This gave his Noble Phantasm the ability to manifest his different personalities as separate and autonomous entities. Though they differ in terms of build and sex, the different personas share similar characteristics: they have dark brown skin, purple hair (for those who have it) and wear white skeletal masks. 

Like all other Hassan-i-Sabah, he can be summoned only in the Assassin Class with the class itself acting as a catalyst.

__In Fate/Zero__

~!
Assassin serves as the Servant of Kirei Kotomine in the 4th Holy Grail War being mainly occupied with reconnaissance duties. The main personality that interfaces with Kirei is a young woman by the name of Asako.!~ 




The leader of a large group of bandits made up of various thugs and wandering seikishi. Though Ran calls her mother, it might not be from blood relation, as some of the bandits refer to her the same way. Her bandit gang attacks the Havoniwa vacation resort in order to capture Dagmyer Mest, a rare male sekishi. After being brought to the bandits hideout, Korudine immediately falls for Dagmyer, and the two begin a physical relationship. Her operational limits in a sekijin a quite low compared to the average seikishi, hense, her status as a wanderer.   ~!After being smuggled into the Holy Land by Dagmyer, Korudine and her bandits take down the Holy Land's defenses from the inside, forcing the students and faculty to abandon the school. However, when Kenshi boards his sekijin, Korudine finds herself woefully outmatched, and is taken down quickly. She next appears when the Swan enters the Havoniwan capital, in command of the meteor fall, Havoniwa's defensive fortress. Before she can finish off the Swan, Yukine damages the bridge which causes the meteor fall to sink to an altitude where Kenshi can destroy one of it's pillars. Knocked of balance, the meteor fall topples over and crashes to the ground, along with Korudine and some of her bandits. It's not directly shown if she dies or not, as she's never seen again.!~

Reia is introduced as a member of the church who arrives at the Swan after being attacked by Ran's bandit thugs, presumably to keep an eye on Kenshi on behalf of the church. She becomes interested in Kenshi's family after he tells her that his mother is also named Reia.    ~!After arriving at the barrier workshop, Reia steals an item that is supposed to help stop Gaia, and reveals herself to be Neizai. As Ulyte sometimes transforms into Reia, he dons the disguise of Neizai whenever he switches bodies, so that no one knows of Reia's existence, or the fact that he and Reia are in the same body. In the last episode, when Ulyte's body finally fails him for good, Reia takes over permenantly.!~
