Background / History

Zouken Matou appoints Yanye as Berserker's Master and has him incorporate forbidden clauses into the summoning chant, granting Berserker Mad Enhancement. Yanye's parasitic Magic Circuits make the ritual agonizing: his body convulses, capillaries burst, and his remaining right eye sheds blood, yet he persists because of the burden he has taken on. 7

Yanye initially intends to save Sakura by obtaining the Holy Grail and trading it to Zouken. During Berserker's confrontation with Jizi, Rin recognizes him as “Uncle Yanye” and pleads with him to save the wounded Assassin instead. Jizi challenges his plan, arguing that a Grail-bearing Zouken would remain a danger to Sakura; Yanye does not immediately agree, but begins to waver. 23

After Jizi explains that he could use the Holy Grail's wish for Sakura himself rather than surrender it to Zouken, Yanye enters an alliance with her and Berserker. Though suspicious of Jizi's methods, he accepts her intelligence and support as valuable to Sakura's rescue. 35

Yanye returns to the Matou residence and openly defies Zouken after learning that Sakura is being subjected to further modification. He commands Berserker to attack Zouken while Jizi removes the Crest Worms from both Sakura and Yanye, freeing him from Zouken's direct influence despite his severely damaged health. 36

He later agrees to cooperate in Jizi's plan to expose the corruption behind the Holy Grail War and purify the Grail. His Command Seals are transferred to Sakura, allowing Berserker's Knight of Owner to make the Calm Amulet a Noble Phantasm capable of restoring Berserker's sanity. 39

Appearance

Yanye is a middle-aged man whose prolonged use of parasitic magecraft has left him physically ruined. He often conceals his disfigured face beneath a hood, while his voice has become harsh and prematurely aged. 23 35 36

• His remaining right eye can weep blood when he activates his Magic Circuits. 7
• Physical exertion and emotional agitation trigger violent coughing, blood loss, and the expulsion of parasites from his body. 35
• He commonly wears a hooded sweatshirt that obscures his face. 36

Personality

Yanye's defining motivation is protecting Sakura. His determination persists even when his body is failing, and he openly rejects Zouken's treatment of her as a tool for the Matou family. 35 36

He can be reckless when Sakura is involved; his original Grail-for-Sakura plan overlooks that, as the victorious Master, he could make the wish himself. However, he is not blindly compliant: he demands evidence from Jizi before accepting her alliance and remains wary of her motives even after choosing to cooperate. 35 39

Yanye shares Jizi's stated attraction to young girls, an uncomfortable trait used as a source of immediate comedic rapport between them. 35

Abilities & Skills

Magecraft and Parasitic Magic Circuits

Yanye's Magic Circuits are parasitic organisms embedded in his body rather than ordinary circuits. Their activation inflicts extreme physical pain and steadily worsens his condition. 7

• The summoning of Berserker causes convulsions, ruptured capillaries, and bloody tears. 7
• His damaged body cannot withstand intense exertion without coughing blood and losing control of his breathing. 35
• Jizi later removes the parasites within him using Stripe, preventing Zouken from affecting him through the Crest Worms. 36

Berserker Mastership

Yanye summons Berserker under Mad Enhancement and attempts to command or pacify him throughout the war. 7 11

• He uses Berserker as his primary combat force, including ordering an attack on Zouken at the Matou residence. 36
• Berserker's madness makes him difficult for Yanye to control reliably. 11 39
• After the Command Seals are transferred to Sakura, Berserker's Mana supply and the Calm Amulet's effect are supported through Sakura instead. 39

Relationships

• Sakura Matou — Yanye's central concern; he opposes Zouken to protect her and ultimately supports a plan that allows her to help Berserker without being harmed. 35 36 39
• Zouken Matou — His Matou-family adversary. Yanye rejects Zouken's exploitation of Sakura and commands Berserker to attack him. 23 36
• Jizi — Initially regarded with suspicion, but becomes his strategist and ally after convincing him to pursue Sakura's rescue directly. 23 35 39
• Berserker — Yanye's summoned Servant. Their partnership is hindered by Mad Enhancement and Berserker's lack of consistent lucidity. 7 11 39
• Rin Tohsaka — Rin knows him as “Uncle Yanye” and trusts him enough to beg him to save Jizi. 23
• Tokiomi Tohsaka — A target of Yanye's resentment; one of his stated goals within the alliance is to defeat him. 40
• Rider — Joins the broader alliance after Jizi negotiates a mutual-defense arrangement centered on purifying the Holy Grail. 40

Trivia

• Jizi initially pretends she can understand Berserker's roars, impressing Yanye with supposed intelligence-gathering. Yanye later realizes she had been bluffing and using prior information instead. 35 39
