Alex was the son of Poseidon, the God of the Sea, and the recognized King of the entire coastal continent. To protect the woman he loved, he deliberately concealed his royal identity and disguised himself as an ordinary farmer, quietly spending five years of resources helping the down-and-out Amy family rise into the nobility. Amy, however, only had eyes for power and status. She despised the farmer-like Alex from the bottom of her heart. At a noble banquet, together with her mother Monica and her admirer Blake, she publicly humiliated and expelled Alex, tearing up their engagement with her own hands and trampling on the castle deed and the treasured Heart of the Ocean he had given her. On the way, Queen Helena of the Odin Empire was besieged by werewolves. Alex stepped in to save her and gifted her the Sea Hunter's Blade, a weapon capable of suppressing werewolves. Helena fell for him at first sight and offered to marry him with her entire empire as dowry, but Alex politely declined, still devoted to Amy. When a large pack of werewolves attacked the Odin castle, the Sea Blade unleashed its divine power and drove back the wolves. Upon learning that Alex had gone to Amy's banquet, Helena immediately set off for Moore Castle. At the banquet, Amy and her companions continued to belittle and expel Alex, even ordering silver-armored knights to strip him of his royal cloak and the Trident of Poseidon. The instant the knights moved to act, Alex stopped hiding, revealing his kingly regalia, his identity on the verge of being exposed. Helena arrived just in time and publicly declared Alex to be the future sovereign of the Odin Empire. All the nobles present—Amy, Monica, Blake—were plunged into extreme shock and utter collapse.
