Sebastian, a prince of the Kingdom of Valerius, witnessed his mother’s death at the hands of Queen Morgana during his youth. To survive, he concealed his extraordinary powers of light, masquerading as an idle, dissolute noble. When forces from the Abyss challenged the Holy See, Sebastian revealed his true strength during the tournament held to select the Saintess, repelling powerful adversaries. Subsequently drawn into court intrigues and framed by the Queen, he systematically gathered evidence to expose the truth behind past events, clear his name, and unmask the true mastermind, ultimately shouldering the heavy responsibility of protecting both his kingdom and the Holy See.
