Sven follows a strict code of chivalry; he is always respectful to women and children unless either appear to be dangerous towards others. He tends to also act very proper. He is often irritated by Train Heartnet's capricious personality and is usually dragged into trouble and even more debt because of Train's attitude and habits. Throughout the series, he tends to get severely wounded but never backs down from his task or his code. He is also noted for being a creative thinker and always calm even in the most dangerous of circumstances.
