Marco is a nice and friendly young man with white hair and light green eyes. He is very nonchalant and considers life as a sort of game, with no real consequences. Despite his laid-back attitude, he is highly considerate of the feelings of others, and goes out of his way to help them. He has a soft spot for animals, especially those who need care. While he generally comes off as someone who doesn't take things too seriously, he is very good at observing people and seeing past their appearance.
