Jang-Gun is the main protagonist of the series, being a master mage at Lost Saga. He generally uses fire magic, especially the spell Fireball. He is the leader of the team Triple Threat, composed of himself, Ah-dol, and Boromir. He is intelligent enough to manipulate most people, and has even caused AIs to doubt their own existences. His intelligence is arguably his most valuable tool in battle, even with master level skills and his aspirations to become a Grand Mage.
