Reborn after a past life as a peerless and ruthless king, the now-teenage Arthur Leywin has become an adventurer with guidance from his mentor, Jasmine Flamesworth. He is still far from his aim of growing stronger than he was before, yet his skill surpasses what anyone expected of him. His elven friend Tessia Eralith, a princess of the Elenoir Kingdom, has also taken up adventuring, charged with building goodwill with human kingdoms after long hostility between the two races. A mysterious group now threatens that fragile peace. Arthur also sets out on one last mission with Jasmine, and it ends in a tragedy nobody foresaw. The second season of the action fantasy adventure runs for 12 episodes.
