The only major NPC in Marina's life is Professor Theo, her creator and the person she takes care of. A genius roboticist and notorious mad scientist, he's not without his eccentricities. Theo is an accomplished lech and often tries to grab on to Marina when he thinks she's not paying attention, which usually results in him getting punished or outright thrown across the continent. Despite this, she does care for his safety and is grateful to him for creating her, and usually is quite respectful around him. In the worst way possible.
