20 The Professional by DocHoliday0316
The Fourth Holy Grail War approaches, and Kiritsugu Emiya prepares to summon the legendary King Arthur under the Saber class. However, rather than receiving the King of Knights, he gets a white-haired man who claims to be a professional. Crossover between Fate/Zero and The Witcher 3: Wild Hunt. One shot.
