Yvin

A wandering adventurer who never stays in one place too long, and tends to call people Chumpy when he forgets their names. Often smirking and made of class and sass, Yvin enjoys interjecting into people's business if he thinks it'll be interesting. He ends up helping Ciel and Florien run away from Amarine, only to stalk them in hopes of turning Ciel in for prize money. However, he gets attached to them quickly and forgets why he's tailing them in the first place. Despite what people assume of him because of his appearance and personality, he isn't a thief... But he'll steal your heart. [From official bio]
