Artis is the Explorers' Association accountant, and also the one who keeps track of special enemies the main trio defeats.

He will give the trio the Hard Mode medal after Maki's tutorial, which can get you some Special Medals after beating bosses with it equipped. You'll have to beat the main boss fight, though, so if you miss it, you'll have to buy it from Caravan.
