Kariya is the uncle of Shinji Matō and Master of Berserker. He is the only member of the Matō family who truly loves Sakura Matō like a daughter, and harbors a very strong grudge against Tokiomi, who allowed his younger child to be adopted by Zōken. Kariya had previously left the Matō family ten years prior to the 4th Holy Grail War out of disgust for his own family, but returns and makes a deal with Zōken Matō that he will win the Grail War in exchange for Sakura's freedom. He is in love with Aoi (his childhood friend), although he stepped down after she chose to marry Tokiomi instead. Due to his lack of formal training, Kariya was implanted with the same magical worms as Sakura. This caused a number of side effects as the worms would literally eat away at their host, causing Kariya's health to progressively fail in return for significantly expanding his magic circuits and magical potential. By the time of his summoning of a Servant, Kariya's hair had turned white and the nerves on the left side of his face were dead. In addition, his natural lifespan had been shortened to such an extent that Zōken estimated he would only live on for one additional year. However, despite the Crest Worms and his own accelerated training, Kariya remained severely lacking as a Magus. At Zōken's behest, he compensated for this by summoning the most powerful of the seven Servant classes, the Servant of Mad Enhancement, Berserker. However, the high volume of magical energy required to maintain Berserker causes him frequent, severe pain. He dies after exhausting his energy and passes away while dreaming of Aoi, Rin, Sakura, and the life he wished he could have had with them.
