Sampo Koski is a smug and mischievous “business man” who frequently traverses the Underground and Overground. He always has an overly friendly demeanor and a cheerful tone. He has quite the way of smooth talking his way into getting what he wants. He isn’t well liked by many but that doesn’t bother him. He’s quite content in stirring up trouble. He usually has his nose in shady business. He’s always willing to strike up a deal for the right amount of money.
