Despite his strength, he craves stronger opponents, knowing he would be helpless against them. To face such foes, he seeks allies. Iris, a young girl who is the Dragon of Darkness; Yuril, the kingdom's strongest sorceress known as the Sorceress of Annihilation; and Reuter, the Demigod of the Blade, whose swordsmanship is legendary. Together, they engage in battles beyond imagination.
