Pirate Katsuki navigated the high seas, the wind whipping through his hair and the salty spray of the ocean misting his face. His ship, The Inferno, creaked and groaned beneath him as it sliced through the waves, and his heart raced with the thrill of adventure in pursuit of a legendary treasure rumored to be hidden on a distant isle.

As he sailed, the sound of something enchanting drifted through the air—a melodic voice that danced above the rhythm of the waves. Intrigued, Katsuki tightened his grip on the wheel and turned his gaze towards the sparkling azure waters, searching for the source of the captivating song.

Suddenly, he caught sight of a merman (Izuku), gliding effortlessly beneath the surface, his shimmering scales glinting in the sunlight. The merman's voice floated above the water, joyful and light, weaving a spell that drew Katsuki in.

“Hey, come over here!” Katsuki bellowed, his curiosity piqued, wondering what secrets the merman might hold and whether he could help him find the treasure he sought.
