A Love Across Two Seas - Vocaloid 神威がくぽx巡音ルカ

💜💗💜💗💜 Story 💗💜💗💜💗 Far beneath the sea, in a place where sunlight could no longer fully reach, there lay a mysterious kingdom known to humans on land as the **Moon-Tide Sea**. There was no true night there. Countless luminous corals grew along the underwater mountains, silver-blue seagrass swayed gently with the currents, and enormous crystal shells lay scattered across the seabed like fallen stars. At the deepest point of the sea stood a magnificent palace built from white coral, pearls, and blue crystal. Whenever moonlight from the surface penetrated hundreds of meters through the water, the highest dome of the palace would refract it into shimmering ribbons of light, like an aurora beneath the sea. This was the royal capital of the merfolk. And **Kamui Gakupo** was the future king of these waters. He possessed strikingly long violet hair that spread through the water like blooming wisteria. Two distinctive strands before his ears extended all the way to his waist, remaining clearly visible even in strong currents. His eyes were a deep, vivid violet, and his tall, powerful body carried the strength of a warrior—broad shoulders, a muscular chest, and a disciplined grace earned through years of battle. Below his waist, his body transformed into a magnificent deep-purple fish tail covered in fine scales. The color gradually softened toward the fins, fading into a translucent lavender. Many people in the kingdom respected him. Some even feared him. Gakupo was not only the crown prince, but also the strongest warrior guarding the borders of the realm. Yet **Megurine Luka** had never been afraid of him. “Gakupo.” A familiar voice came from behind him. Gakupo, who had been inspecting the waters outside the palace, stopped. He did not even need to turn around. His expression had already softened. A flash of pink emerged from behind the coral reef. Luka’s long pink hair floated gently through the sea like clouds colored by dawn. Her eyes were a clear, beautiful blue. Strings of pearls and aquamarines decorated her waist, while her pale-blue tail shimmered beneath the sunlight filtering from above. Unlike Gakupo, however, she had not been born in this kingdom. Luka was the princess of the northern **Azure-Tide Kingdom**. For nearly a hundred years, the two kingdoms had been divided by disputes over territory, shipping routes, and ancient grudges. Their meeting had never been planned. It had been an accident. Years ago, Luka had become separated from her guards during a violent storm. The underwater currents had grown many times stronger than usual, dragging her far into unfamiliar waters. There, she had been attacked by a monster from the deep. Just when she believed there was no escape, a violet figure tore through the darkness. Gakupo had not asked who she was. He had not cared which kingdom the royal ornament in her hair belonged to. He had simply drawn the crystal blade from his waist and placed himself between Luka and the monster. “Stay behind me.” Those were the first words he had ever spoken to her. Later, Luka would often tease him about it. “You sounded so commanding even though we had only just met.” And every time, Gakupo would answer calmly, “You looked as though you needed someone to protect you.” “I’m a princess.” “I know.” “I can fight too.” “I know that as well.” “Then why do you keep protecting me?” At that point, Gakupo would usually fall silent. Because the real answer was far too simple. He simply could not bear to see her hurt. Now, after years of negotiation, the two kingdoms had finally signed a peace treaty. Luka was staying in Gakupo’s palace as an official envoy. But everyone knew that the word *envoy* was little more than a convenient excuse. “You came all the way out here by yourself again.” Luka swam beside him and gently hooked her fingers around his. “I’m only doing a routine patrol,” Gakupo replied. “You said the same thing yesterday.” “Yesterday was also a routine patrol.” Luka could not help laughing. Then she moved closer and gently touched a fading scar across his chest. It had been left by a border battle three days earlier. Gakupo instinctively caught her wrist. “It’s already healed.” “You always do this.” “Do what?” “You get hurt and never tell me.” Her voice became quiet. Gakupo had been about to answer, but when he saw the unmistakable worry in her blue eyes, he fell silent. The sea flowed slowly between them. A strand of Luka’s pink hair brushed against his arm before drifting away again. At last, Gakupo pulled her hand against his chest. Beneath her palm, she could feel his heartbeat—steady and strong. “I’m really fine.” Luka listened to it for a moment. “Next time, at least tell me.” “All right.” “Really?” “Really.” Only then did she smile again. But in the next moment, a deep rumbling echoed through the distance. The entire coral reef trembled. Schools of fish burst from behind the rocks in panic, scattering in every direction. Gakupo’s expression changed instantly. He turned, sweeping his violet tail through the water as he moved Luka protectively behind him. In the distance, a black current was spreading from a massive trench in the seabed. “The Abyssal Tide…” Luka’s smile vanished. It was one of the most dangerous natural disasters in the Moon-Tide Sea. It appeared perhaps once every few decades. Whenever the ancient currents deep beneath the seabed became unstable, freezing water from the abyss would erupt through the trenches, forming violent currents powerful enough to destroy entire coral forests. And now, that current was heading directly toward the royal capital. “Return to the palace,” Gakupo said. “What about you?” “I’ll seal the trench.” “By yourself?” “There isn’t enough time to gather all the guards.” “So you’re planning to go alone?” Gakupo did not answer. His silence told her everything. Luka tightened her grip on his hand. “Then I’m going too.” “Luka.” “Have you forgotten?” She swam directly in front of him and looked straight into his violet eyes. “I’m royalty too.” “That is exactly why—” “A royal’s responsibility is not to hide in a palace and wait for someone else to protect them.” Gakupo stared at her for a moment. Then Luka smiled. “The first time we met, you told me to stay behind you.” She squeezed his hand. “This time, I want to stand beside you.” The black tide continued to advance. After several seconds of silence, Gakupo finally tightened his fingers around hers. “Do not leave my side.” “You either.” Their tails moved at the same time. Purple and blue became two streaks of light as they raced toward the abyssal trench. The closer they came, the stronger the current became. Luka’s long pink hair streamed behind her while Gakupo remained slightly ahead and to the outer side, using his own body to shield her from the worst of the turbulence. At the center of the trench stood an ancient pillar dedicated to the Sea God. It had shattered. That fracture was what had allowed the Abyssal Tide to break free. “We have to reactivate the pillar!” Luka shouted. “I’ll hold back the current. You go to the pillar!” “That’s too dangerous!” Gakupo turned his head toward her. There was no hesitation in his violet eyes. “Trust me.” Luka bit her lip. She knew that arguing now would only waste precious time. So she nodded. “Then you have to trust me too.” In the next instant, Gakupo released her hand. He swam directly toward the black tide. His deep-purple tail swept powerfully through the water, and magic surged along his arms, forming a massive violet barrier. The Abyssal Tide crashed into it. Gakupo was forced backward several meters. “Gakupo!” “Go!” Luka turned and rushed toward the broken pillar. She placed both hands against its shattered crystal core. Blue light began to spread from her palms. But the pillar did not respond. Once. Twice. Three times. Behind her came the sound of the barrier cracking. Luka turned her head. Cuts had appeared across Gakupo’s arms where the violent current had torn at him. His long violet hair whipped wildly through the darkness. Yet he refused to move. “Luka!” His voice broke through the roar of the currents. “Look at me!” She froze. “Don’t look into the abyss.” Gakupo struggled to reach one hand toward her. “Just look at me.” In that moment, countless memories flooded back to her. The back that had shielded her when they first met. The hands they had secretly held in the palace gardens. The nights they had spent together beneath the moonlit sea. And this foolish prince who never admitted when he was hurting, yet always noticed the smallest sadness in her eyes. Luka closed her eyes. She was no longer afraid. A brilliant wave of blue magic erupted around her. One by one, the sections of the ancient pillar began to glow again. The final fracture disappeared beneath the light. “We did it!” The Abyssal Tide stopped instantly. But at the same moment, with the force of the current suddenly gone, Gakupo’s exhausted body began to fall helplessly into the trench. “Gakupo!” Luka raced after him without hesitation. She reached out. Almost. Just a little farther. At the very edge of the darkness, she finally caught his hand. Gakupo slowly opened his eyes. “You… really never listen…” “Be quiet.” Luka’s eyes were already red. She wrapped her arms tightly around him. “This time, I’m the one saving you.” Gakupo seemed as though he wanted to laugh. Instead, he gently rested his forehead against hers. Their tails curved naturally around one another in the now peaceful water. Purple and blue fins crossed together. From a distance, they formed the shape of a single heart. Several days later, the royal capital held a grand celebration in their honor. But halfway through the banquet, the two guests of honor disappeared. Before the enormous circular window at the highest level of the palace, Luka leaned against a white coral pillar and watched the sunlight descending through the sea. A familiar current approached from behind. She did not turn around. “Your Highness, disappearing from your own celebration is not very proper behavior for a prince.” Gakupo swam beside her. “I don’t believe a princess who disappeared first has any right to criticize me.” Luka laughed. Gakupo extended his hand. Without hesitation, she placed hers into it. Their fingers intertwined. “Luka.” “Hmm?” “The peace treaty has been completed.” “I know.” “You’ll have to return to the Azure-Tide Kingdom soon.” The smile on Luka’s face faded slightly. “…Yes.” Gakupo fell silent for a long time. The prince who had never hesitated on a battlefield now looked as though he had forgotten how to speak. Finally, he tightened his grip on her hand. “Stay.” Luka looked up. The tips of Gakupo’s ears seemed slightly red. “Not as an envoy.” He lowered his voice. “And not as the princess of the Azure-Tide Kingdom.” Luka could feel her heart beginning to race. “Then as what?” Gakupo looked directly into her eyes. His violet gaze reflected only her. “As my queen.” Luka’s blue eyes widened. For several seconds, she said nothing. Then she suddenly wrapped her arms around his neck. The force sent Gakupo drifting backward, but he immediately placed his hands around her waist. “Is that your answer?” he asked. “No.” Luka moved close to his ear. “This is.” She gently kissed him. Her long pink hair intertwined with his flowing violet strands. Far above them, thousands of moonlight fish swam over the palace, scattering silver glimmers around the couple like falling stars. Gakupo drew her closer. A long time later, Luka rested her head against his chest. “Actually, I had already decided.” “Decided what?” “If you didn’t ask me to stay, I was going to stay anyway.” Gakupo laughed softly. “Then it seems I worried for nothing.” “It isn’t the same.” Luka lifted her head and gently touched his face. “Because I wanted to hear you say it.” Her blue eyes curved into a warm smile. “Say it again.” Gakupo looked at her. This time, there was no hesitation. “Luka.” He took her hand and placed it over his heart. “Stay by my side.” Their violet and blue tails slowly intertwined again. Just like the heart they had formed together over the abyss. “All right.” Luka smiled. “Not just for now.” She intertwined her fingers with his once more. “I’ll stay with you forever.” Sunlight traveled across the distant surface and descended into the deep-blue royal capital. There, beneath the illuminated sea, the violet-haired mermaid prince and the pink-haired mermaid princess embraced once again. From that day forward, the currents that had once separated their kingdoms were no longer borders. They became roads connecting one home to another. And in later years, the merfolk would tell a story. Whenever the moon was full, two lights could sometimes be seen racing through the depths of the Moon-Tide Sea. One was violet. The other was blue. They would pass through coral forests, cross ancient sleeping temples, and finally meet beneath the moonlight before the royal palace. For there had once been a mermaid prince who faced the abyss for the one he loved. And a mermaid princess who followed him into that abyss without hesitation. Once, they had belonged to two different seas. In the end, they chose to become each other’s only home.
