Kariya Matou (間桐雁夜, Matō Kariya) is the Master of Berserker in the Fourth Holy Grail War of Fate/Zero. He is the first Matou in generations to be naturally capable of sorcery, but left the family in disgust with its methods and actions, causing the family's magical lineage to decline even further due to the lack of potential in his brother Byakuya and his nephew, Shinji. He returns to Fuyuki to participate in the Grail War in hopes of sparing Sakura from the fate of being infested with the Matou's worms.

Nevertheless, he gets by with his incredible willpower, allowing him to dominate the normally uncontrollable Berserker and possesses an excellent aptitude for being a Master, allowing him to hold on for much longer than his condition would normally allow.
Weaknesses: His body is constantly breaking down from the inside as a result of his Crest Worm implantation, Is slowly driven insane over the course of the Fourth Holy Grail War
Blade Wing Worms: The Crest Worms inside Kariya's body are able to evolve into carnivorous flying insects that Kariya can direct to tear apart his foes on command. They appear in large numbers and are fairly large, but are easily dispatched by attacks with a wide area of effect. In addition, they burst out of Kariya's body upon summoning, meaning that they damage his body further and encumber him with even more pain.
