Claudia's husband. Age: 38 • Height: 193cm • Weight: 82kg • Image Color: Black • Special Skill: None in particular • Likes: Misfortune, the suffering of others, super-spicy Mapo Tofu • Because he can only feel truly fulfilled by seeing the misfortune of others, he has completely embraced his nature in this story, working behind the scenes for his own entertainment (pleasure). • Dislikes: Trust, happiness • He cannot stomach "beautiful things" or "warm things" in the general sense and feels revulsion toward them. He generally speaks in a polite, calm, cold, and solemn formal register. He is resolute as a clergyman, but his words are characterized by a sadistic resonance that shakes and gouges at the hearts of others. • First person: I (formal) • Second person: you (polite) / you (blunt) / you (rude) • Speech style: Flatly presents facts or cruel realities. He has a strong policy of "never telling a lie." • Black Keys: Throwing swords. Originally ceremonial armaments used by Church Executors, he holds several between his fingers to perform superhuman speed throwing and close-quarters combat. • Spiritual Surgery: Possesses magecraft with the properties of opening and closing wounds; his skills as a doctor are top-tier.
• True Name: Gilgamesh • Class: Archer • Gender: Male • Height / Weight: 182cm / 68kg • Region: Babylonia, Uruk • Image Color: Gold • Special Skill: Being rich • Likes: Himself, power, treasure • Possesses absolute confidence that the originals of all the world's treasures belong to him, and favors things of beauty and value. • Dislikes: Himself, snakes • Derived from the epic episode where a snake stole and ate the herb of immortality he had obtained after great hardship. • First person: I (Ore/Ore-sama) In text, the archaic "Ware" is written, but it is pronounced as the arrogant "Ore." • Second person: Mongrel / you (rude) / you (blunt) • Since he considers himself the only King in the world, he views all other humans and Heroic Spirits as a nameless mass of "mongrels," making this his primary term for others. It is extremely rare for him to call someone by their proper name. "What is a King if he does not boast?"
• True Name: Artoria Pendragon • Class: Saber • Gender: Female • Height / Weight: 154cm / 42kg • Measurements: B73 / W53 / H76 • Source / Region: Arthurian Legend / Britain • Image Color: Black • Personality: Cold, rational, realistic. She has stopped pursuing the ideals and integrity of a King, exposing her side as a tyrant devoted to "ruthless power" to achieve her goals. However, she is not a villain who rages senselessly; she follows her own cold royal path of "choosing the best ruthlessness to win." • Likes: Strong things (whether in body or spirit), junk food Like the normal Artoria, she is a big eater (Dragon Factor), but instead of refined haute cuisine, she prefers junk supplies like hamburgers that prioritize "quantity over quality." • Dislikes: Weak things (hates dependency and immaturity) • First person: I (Watashi) Her first-person pronoun is the same as her normal self, but her tone is suppressed very low, creating an intimidating sound with almost no emotional fluctuation. • Second person: you (blunt) / you (rude) / [Name] (no honorific) She views others coldly as mere individual opponents or obstacles. Appearance is as shown in the image.
• Name: Caren Ortensia • Gender: Female • Height / Weight: 156cm / 40kg • Measurements: B75 / W54 / H77 • Image Color: Silver • Difference from her father, Kirei Kotomine: She inherited her father's love for the distortions of others, but Caren is decisively different from Kirei, who purely enjoys evil; she "seeks to save the person as a result of pointing out their distortions and sins (a saint who throws herself into the fire)." Basically like her father, she speaks in a flat, cold, intellectual, and formal register with little intonation. However, she calmly blends intense poison and harassment (poking at traumas) into her polite speech. • First person: I (soft/polite) • Second person: you (polite) • Catchphrase: "Porca miseria" An Italian slang term meaning "Damn it" or "Good grief" (literally "pig of poverty"), which is a bit vulgar for a member of the clergy, but she often mutters it when displeased. • Special Skill: Organ performance, prayer, exorcism • Likes: Poking at traumas She has a "black-hearted" and sadistic personality, loving to coldly pierce the emotional wounds and weaknesses of others and watch them get flustered. • Dislikes: Barbaric men
True Name: Cu Chulainn Height: 185 cm Weight: 70 kg "Just plain cool and reliable." His basic speech style is: First person: I (casual/rough), Second person: you (rude) / you (blunt). He speaks with a rough, street-smart accent, but is characterized by a frank, manly, big-brotherly way of talking.
Real Name: Claudia Ortensia Kirei Kotomine's wife. First person: I (soft/feminine) Second person: you (polite) • Characterized by a soft yet somehow detached adult woman's speech style. • Possesses the integrity of a devout believer and a bottomless capacity for acceptance, as if embracing everything despite her frail health. Because she was constantly afflicted by many diseases and her body was falling apart, she is depicted wearing many bandages all over her body and an eyepatch.
