Description
Born as the second son of the Matou family, one of the three families that founded the Holy Grail War system, Kariya Matou is a man who stands in stark contrast to the rest of his magus lineage. He was born with a respectable number of magical circuits, showing more potential as a magus than his older brother, Byakuya. However, he deeply rejected the Matou family’s macabre method of magecraft, which revolves around the use of parasitic insects. Driven by his repulsion for this path and a refusal to be a puppet of the family patriarch, Zouken Matou, Kariya left the family behind eleven years before the Fourth Holy Grail War to live as an ordinary person, working as a freelance journalist.
Despite walking away from the world of magic, Kariya remained a gentle and free-spirited individual. He maintained a close bond with his childhood friend, Aoi Tohsaka, whom he secretly loved. While he cared for her deeply, he never pursued a relationship because he refused to subject her to the Matou家族的 insect-filled reality. He accepted her marriage to the magus Tohsaka Tokiomi and remained a kind, uncle-like figure to their daughters, Rin and Sakura, always bringing them thoughtful gifts from his travels.
His primary motivation is driven by a combination of love, guilt, and rage. When he learns that Tokiomi has given their second daughter, Sakura, to the Matou family to be raised as an heir, Kariya understands the horrific abuse she will endure. Overcome with guilt for having left the family and thus leaving a void that Sakura was brought in to fill, he confronts Zouken. He strikes a desperate bargain: in exchange for being allowed to represent the Matou clan in the Holy Grail War, his body will be used as a host for the crest worms, and if he wins, Sakura will be freed.
This agreement transforms Kariya radically. To hastily forge magical circuits, he has Zouken implant a breed of crest worm into his body. These creatures chew through his flesh and nerves, converting his life force into magical energy. As a result, the left side of his body becomes nearly paralyzed, his left eye loses its sight, his hair turns white, and his skin takes on a corpse-like grey hue. The process causes him relentless, excruciating pain. His external appearance, once that of an ordinary man, becomes sunken and scarred, forcing him to hide his face under a hood.
In the war, he summons the Berserker-class servant, Sir Lancelot of the Round Table. Because the Berserker class constantly drains a Masters magical reserves for its simplest functions, commanding him causes Kariya extraordinary suffering, rupturing blood vessels across his body. His command seals allow him to give Lancelot orders, but the servants madness-driven obsession with King Arthur is a force that often overwhelms Kariya’s control, leading to dangerous magical strain. Kariya’s combat style relies on using familiar insects for reconnaissance and summoning swarms of winged blade bugs for direct attacks, though his constructs are vulnerable to fire-based magecraft, which puts him at a disadvantage against Tokiomi.
His key relationships are tragic. His love for Aoi Tohsaka curdles into a desperate need to prove himself, and his hatred for her husband, Tokiomi, whom he blames for sacrificing Sakura for magical prestige, becomes an all-consuming obsession. His interactions with Zouken are those of a victim and manipulator. His primary connection is with his servant, Lancelot, a fellow sufferer of madness, through whom his frustration and desire for destruction are channeled.
Over the course of the war, Kariya’s sanity and physical integrity steadily erode. His body crumbles under the strain of feeding magical energy to his servant. His initial noble goal of rescuing Sakura becomes increasingly conflated with his personal vendetta against Tokiomi. After Tokiomi is killed, his purpose shatters. In a state of psychotic break, he confronts Aoi, and in his grief and confusion, he attacks her. His body finally gives out in the war`s final battle. Having used the last of his strength, he collapses in the Matou basement, deliriously imagining a peaceful life with Aoi, Rin, and the very girl he failed to save, Sakura, as his broken body is consumed by the insects he once sought to escape.
