Alias(es) “Magus Killer” 11
Species/Race Human 72
Gender Male
Affiliation Einzbern family; Chaldea 73 94
Occupation/Role Mercenary magus; nominal Einzbern Master in the Fourth Holy Grail War 73 88
First Appearance Chapter 11 (mentioned) 11

Background

Kiritsugu’s father, Norikatsu Emiya, was subjected to a Sealing Designation; Cornelius Alba led the execution team involved. Touko Aozaki later framed Kiritsugu for Alba’s murder, considering it revenge on his behalf. 11

He became known as the Magus Killer through assassinations of magi in the Middle East, employing modern technology alongside traditional magecraft. This reputation made him the obvious suspect in Alba’s death. 11

Kiritsugu’s lifelong pursuit of humanity’s salvation arose from witnessing suffering and human depravity. When unable to protect Irisviel and Illya from Einzbern control, he concluded that the Holy Grail was his only possible means to save the world—and himself from his despair. 72

Appearance

Kiritsugu is described upon arriving in Fuyuki as a refined, white-haired young man with his hair braided, dressed in unusual clothing and carrying a Chaldea-marked briefcase. 94

  • White hair, styled in braids. 94
  • Carries a briefcase marked with an abstract “c” encircled by a laurel wreath. 94
  • Was also seen at Winter Castle in a black trench coat with a scruffy beard. 69

Personality

Kiritsugu is calculating, secretive, and relentlessly committed once he chooses a course of action. Aoko characterizes him as someone who will carry an ambush through to the end regardless of what is said to him. 151

His composure masks severe insecurity about his ability to protect those closest to him. He worries for Irisviel and Illya, yet feels powerless against Einzbern authority and the Aozaki sisters’ superior magecraft. 70 72

Although he is willing to sacrifice and deceive in pursuit of salvation, he remains attentive to Irisviel’s well-being and maintains a gentle mentor-student bond with Shirou. 94 100

  • Relies on surprise and timing rather than direct confrontation with powerful magi. 73

Story Role / Major Arcs

Framed for Cornelius Alba’s Murder

After Touko kills Cornelius Alba with a C4-filled spider doll, the Clock Tower suspects Kiritsugu because the method resembles his known assassination practices. 11

Einzbern Negotiations and Irisviel’s Double

Kiritsugu is sidelined during the Aozaki sisters’ negotiations with Einzbern and recognizes that he cannot challenge wielders of the Five Great Magics. He becomes distressed when Touko replicates Irisviel’s body and Aoko uses the duplicate to unsettle him. 69 72 73

Fourth Holy Grail War Preparation

Ahdohn selects Kiritsugu as Einzbern’s Master because of his record against magi, but revises the plan so Kiritsugu will secretly support Touko instead. Kiritsugu responds by formulating a covert plan against the Aozaki sisters. 73

Assassin’s Contingency Plan

Kiritsugu meets Assassin, obtains Hydra poison, and inspects the underground construction prepared for her Noble Phantasm. He keeps his own intentions hidden while treating her ritual as a possible fallback if the Aozaki sisters fail. 100

Conflict with Aoko

Kiritsugu ultimately follows through on his decision to ambush Aoko, firing the Contender rifle and striking her with a bullet containing his ashes. 151 153

Trivia

  • The Clock Tower’s investigation into Alba’s death found no evidence connecting Touko to the crime, largely because Kiritsugu’s established methods provided a convincing scapegoat. 11
  • Aoko considers Kiritsugu dangerous enough to prioritize anti-ambush awareness when selecting the Alertness feat. 5
  • Aoko and Touko later condemn Kiritsugu’s actions in Fuyuki City. 129
