Maiya Hisau (久宇舞弥, Hisau Maiya?) is a young woman who acts as Kiritsugu Emiya's assistant during the fourth Holy Grail War. She is cold and professional, which makes it easier for Kiritsugu to act as he needs to.
Little is known about her history, save that Kiritsugu had rescued her from a war-torn land many years ago. When Maiya was a child, she was forced into the army and trained to be a soldier. She later reveals to Irisviel von Einzbern, Kiritsugu's wife, that she had been raped by other soldiers and later lost her child. After rescuing her, Kiritsugu became Maiya's mentor and taught her his way of life. Her real name is unknown; her current name was given to her by Kiritsugu when he created identity documents for her.
When Kiritsugu was hired by the Einzberns to obtain the Holy Grail eight years before the Fourth Heaven's Feel, he entrusted Maiya with all his former equipment - in particular, the gun which allows Kiritsugu to employ his Mystic Code.
She dresses entirely in black, and gives the cold, distant impression of someone who doesn't have a strong sense of self.
Due to having spent her childhood in an environment deprived of humanity Maiya lacks a sense of self. She currently considers that her entire being belongs to Kiritsugu, and asking whether she loves Kiritsugu is like asking whether the innards love the brain. The question itself is meaningless. They share a sexual relationship that contains no real emotions. Kiritsugu sees it mainly as a rehearsal before he betrays Irisviel by allowing her to sacrifice herself and complete the Grail. While it is a form of self-abuse to him, and possibly the sorriest excuse to have an affair, Maiya treasured every second of it.
The design requested for Maiya was a "fighting maiden with a vector pants look" that wasn't Bazett. She has a slender and flexible image with a costume that shows no particular ethnicity and gives the feeling of "Where is she actually from?" She gives Takashi Takeuchi an empty, ephemeral impression that doesn't give off a sense of self when he draws her. He also didn't notice her hairstyle overlaps with Waver's until he first did a full body illustration of her.
Maiya reunites with Kiritsugu when he arrives in Japan shortly before the Fourth Heaven's Feel, having prepared all the weaponry he requires for the upcoming Holy Grail War. Armed with a Steyr AUG, she aids Kiritsugu by helping him snipe opposing Masters. While Irisviel is initially uneasy around Maiya, they develop a mutual respect when Irisviel recognizes that Maiya has dedicated her life to protecting Kiritsugu.
When Kiritsugu attempts to attack Kayneth Archibald El-Melloi at his stronghold, she ends up working with Irisviel to ensure that Kiritsugu's identity remains a secret from Kotomine when El-Melloi retaliates by attacking the Einzbern Castle. During the fight of Iri and Maiya against Kirei Kotomine, Maiya is severely wounded several times by him because she tries to protect Iri against him. During a subsequent battle to defeat Caster, Maiya captures Sola-Ui Nuada-Re Sophia-Ri and cuts off her arm in order for Kiritsugu to use the woman as a hostage against Lord El-Melloi. After Kiritsugu forces Lord El-Melloi to forfeit in the war, Maiya snipes both El-Melloi and Sola-Ui.
After the death of Lord El-Melloi, Maiya joins Irisviel and Saber at Kiritsugu's new stronghold after the Einzbern Castle is compromised and provides Saber with a motorcycle prepared by Kiritsugu after he learned that she was capable of driving the car he had given Irisviel. Maiya learns that Irisviel's condition is deteriorating, but agrees to Irisviel's request to conceal the truth from Saber. The three women later meet with Tokiomi Tohsaka and Kotomine to discuss Tokiomi's proposal for the remainder of the Fourth Heaven's Feel, though Irisviel and Maiya reject most of the terms.
During the last day of the war, Maiya is assigned to protect Irisviel, who is to be the vessel of the Holy Grail. After conversing briefly with Irisviel, they are attacked by Rider (Berserker in disguise); Maiya is fatally injured attempting to stop the Servant from kidnapping Irisviel and dies shortly after Kiritsugu arrives to try and save them. She had resolved herself to die and disappear unrewarded and alone, so dying in Kiritsugu's arms was likely a joy beyond her wildest dreams.
Maiya, like Kiritsugu, is not a normal magus. He only taught her what was necessary to complete her duties, so they can not be said to have a true master and apprentice relationship. She is only slightly better than Azaka Kokutou in her skills in magecraft, but she makes up for that with her experience as a professional killer who can wield even the crudest weapons to deadly effect. Magecraft is just a tool for her to accomplish her goals, so she is skilled enough to be called a user of "deadly magecraft."
Like Kiritsugu, she use a Steyr AUG A1 and a Calico M950 as weapons. She later utilizes a 9mm Glock handgun, likely a Glock 19, as a sidearm, and it was most likely picked by herself rather than Kiritsugu.

Comment for Maiya
Takeuchi: I am afraid that I have not drawn Miss Maiya very much. She has a slender and flexible image. She gives me an empty, ephemeral impression from which I cannot feel a strong sense of self, but this seems to be the correct interpretation.
Urobuchi: I requested a fighting maiden with vector pants look that wasn't Bazett, but I fairly like the costume that shows no particular ethnicity.
Takeuchi: You get a feel of "Where is she actually from", huh? I wanted her to have a just slightly happier ending/
Urobuchi: She herself was resolved to disappear unrewarded and alone, so dying in Kiritsugu's arms was most likely as joy beyond her wildest dreams.

Character Designs, Animation Director
At first, I thought that he (Kiritsugu) was a character who wasn't capable of expressing much emotion, but I think that in the latter half of the show, me might have managed to bring out the side of him that's rather frail and weak in comparison to his hard exterior. And since he's a character with the strength to blot that out, it's a difficult thing to do.
A freelance Mage-killer. Asked to marry into the Einzbern family, and then becomes their trump card in the Holy Grail War. He uses the magic of Innate Time Control to manipulate and alter the flow of time within his own body. As one would expect of an assassin who suppresses his emotions, his face is blank and his eyes are vacant. Tomonori Sudo was in charge of the character design for the anime version.
Kiritsugu Emiya's partner. She met Kiritsugu on the battlefield, and has fought her entire life like a machine, considering herself a part whose function is to help Kiritsugu. She dresses entirely in black, and gives the cold, distant impression of someone who doesn't have a strong sense of self. Like Kiritsugu, she use a Steyr AUG and Calico M950 as weapons.
Kiritsugu Emiya (as a boy)
He spent his youth wandering around the world with his father, Norikata Emiya, who was on the run from the Mage's Association. At his point, he is still a dreamer of a boy who knows nothing of the world. His Shining eyes and tanned skin make him look cheerful. However, he comes face to face with harsh reality on Arimago Island.
Kiritsugu Emiya (as a young man)
Kiritsugu spent his days traveling around the world hunting down evil Mages. At first, he only got in Natalia's way, but he eventually becomes her partner and equal. However, living the life of a Mage-Killer forces him to confront a harsh reality.

Maiya Hisau [Person's name]
Assistant of Kiritsugu Emiya. Mistress - it is the word whether to define on her.
Because she spent her childhood in an environment deprived of humanity, Maiya, who lacks a sense of self, considers that her entire being belongs to Kiritsugu Emiya. Asking whether she loves Kiritsugu is like asking whether the innards love the brain. The question itself is meaningless.
Also, to Kiritsugu, allowing his wife to sacrifice herself and complete the Grail is a betrayal towards her love, no matter what others say. However, it is necessary that he does not hesitate in this betrayal. To Kiritsugu, his sexual relationship with Maiya is a rehearsal before this betrayal, a form of self-abuse to steel his nerves while walking down this path. This is probably the sorriest excuse to have an affair, but Maiya treasured every second of it. It is essentially a negative spiral downward without an end.
In terms of skills in magcraft, Maiya is only slightly better than Kokutou Azaka. However, she is a professional killer who can wield even the crudest weapons to deadly effect. In this sense, she is enough to be called a user of 'deadly magecraft'.
 Fate/Zero material - Encyclopedia: Steyr AUG [Armament], p.098 English | Japanese
Steyr AUG [Armament]
The assault rifle used by Hisau Maiya. It seems it's one of the better weapons prepared by Kiritsugu.
As the first successful example of a bullpup rifle, it must have seemed almost bizarre when it was first released.
The fact that it consistently outperformed subsequent bullpup rifles, and is even used as the official weapon of many militaries to this day is, quite frankly, amazing. One of its primary features is its easy-to-disassemble modular construction. However, thanks to the popularity of scenes like the one from Day of the Jackal where the assassin assembles their weapon on the spot, it's often mistaken for a sniper rifle in movies. Well, it does have a sort of "secret weapon" look to it, so I guess I understand.
…Ah, wait, now that I think about it didn't Maiya try to snipe at Kayneth's hotel from the neighboring building?
 Fate/Zero material - Encyclopedia: Glock [Armament], p.095 English | Japanese
The sidearm that Hisau Maiya carries with her. Although it doesn’t have a model number, in the author’s head it is surely Model 19.
It’s hard to imagine that Kiritsugu prepared this gun for her, so most likely Maiya picked it herself.
