Kariya Matou is the uncle of Shinji Matou and the first in his family line to possess magical potential in many generations. Despite this, he grew to detest his family, especially Zouken Matou, leading him to sever all ties more than ten years before the 4th Holy Grail War. Disappointed by Shinji's lack of magical abilities, Zouken blamed Kariya for the decline of the family's magical lineage, particularly because a Matou with magical powers was essential to serve as a Master during the Holy Grail Wars.
Kariya kept in touch with his childhood friend and love interest, Aoi Zenjou, even though he had given up on pursuing her after she married Tokiomi Tousaka. Aoi later had two daughters, Rin and Sakura, both of whom were fond of Kariya.
On the final day of the 4th Holy Grail War, Berserker battles Saber in a fight so intense that it drains more mana than Kariya can supply. With his Servant killed, Kariya manages to return to the Matou estate, where he encounters Sakura. He tells her he has come to save her but collapses at her feet shortly after. Kariya dies with a content smile, comforted by dreams of escaping with Aoi, Sakura, and Rin to start a new family together.
