Sampo is a tall, lean, light-skinned man. He has medium length dark blue hair tipped with slate gray at the neck, and long bangs swept over his left eye. His eyes are slightly downturned and mint green with cat-like pupils. He wears a silver cuff on his right ear. His upper attire includes several layers, the outermost being a magenta suit-like jacket with white and purple accents, short sleeves and long coattails. Under the jacket is an asymmetrical black half-shirt with an open front.
