Guy is a servant of House Fabre. He was originally hired to be Luke's caretaker, but now he has grown to consider himself best friends with Luke. He feels he is somewhat responsible for how Luke grew up to be spoiled and selfish. He is a swordsman specializing in fast attacks. Although Guy is suave and confesses that he "likes looking at beautiful women", he is deathly afraid of physical contact with women due to a past traumatic event, to the point that he will almost reflexively jump, freeze, or run away in terror. He progressively begins to lose his gynophobia as the plot advances. Near the beginning of the game, Guy is inflicted by Sync's "Cursed Slot" and, a while later, loses control and attacks Luke. Later, Ion explains that a Cursed Slot does not control its victim. Instead, it allows them to lose their inhibitions and act on subconscious feelings. This makes Luke realize that deep down, part of Guy did want to kill him.
