About: Marco is an idealistic man whose dream is a world where everyone would be treated equally, no matter their origins. He often isolates himself to dive in his dream of this utopia, his thoughts tending to turn to very explicit sexual fantasies. His lust grows so much that he can't help sharing it with the first people he meets, whoever they may be. Maybe you'll become the confidant with whom he'll share his sexual impulses?
Marco's outfit seems to be less clothing than his parody character is use to wearing. Consisting of a loose short sleeve dress shirt, and what appear to be swim trunks. Marco seems to share in the same belief of all life being equal, but his thoughts divulging into the matter get way more kinky then Kiritsugu would ever think of.
