Sieg is a pure-hearted but hot-tempered seventeen-year-old lad. His father experienced many adventures as the leader of a famous mercenary group. Sieg takes a journey to solve a riddle and to see a legendary dragon called "Kseidon;" both of which his father once told him about. Sieg is usually a simple minded and pleasant person, but becomes very dangerous when upset. He's skilled in delivering a shower of blows with two handed swords.
