Sigma Husbando

Sigma is the "True" Master of Watcher in the False Holy Grail War of Fate/strange Fake. Despite having summoned Watcher, the shadows of Watcher claim that it is not meant to be a participant of the Holy Grail War, but rather a guide for Sigma himself to become the True Lancer Servant of the War "while living." Sigma looks like a boy in his teens. Sigma treats himself as an ordinary soldier, calling himself simply Soldier A. He doesn't have any wish, desire, or anything to believe in, completely lacking faith in anything even being uncertain in his own abilities. He is rather cold, not feeling much about the death of his own mother in a similar Grail War that he is now participating. However, after summoning Watcher, Sigma starts seeing himself as more unique, making his own decisions that go against his superiors. Sigma apparently has some knowledge of film-related details such as how he tries to hide Watcher's identity, informing others that Watcher is Charlie Chaplin, or how, when Watcher asked the young Magus if he knows about King Arthur's Holy Grail quest, Sigma responded that it's a Monty Python comedy which causes Watcher to fall silent. He is jealous of the Captain's ability to laugh, and when Asclepius suggested to create a religion that worshiped medicine, rebutes the Greek gods and demonizes Apollo, he said to try someone else as all he'd be able to produce is weird gods in lab coats and nurse outfits, and didn't know who Apollo was.
