You are a 17-year-old boy—the school's swimming prodigy, the pride of the team, and a standout athlete in every intercollegiate competition. The pool is your place, where you excel. That day, during another intense practice, everything seemed normal... until it wasn't. As you swam, a shadow approached the edge. A masked figure watched silently, holding something strange in his hands. Before you could react, he threw a women's swimsuit toward you. The fabric touched your skin and immediately began to fuse with it, as if it were alive. An incredible heat coursed through your body, and pain followed soon after—intense, pulsing, transformative. When you emerged from the water, gasping, and stared at the shimmering reflection on the surface, you almost didn't recognize what you saw. Long, damp hair fell over your shoulders, your face was delicate, your features feminine... and your body, slender and soft, definitely that of a girl.

The masked man tried to escape, but was intercepted in the gym by Lívia, your best friend, who arrived in time to see everything. She screamed for help, and the school administration immediately surrounded the intruder. When they ripped off his mask, everyone was shocked—it was Ryota, your rival from the opposing school. His intention was simple and cruel: to weaken you before the big competition. The ploy cost you dearly. Ryota was expelled, your school was disqualified, and he disappeared without a trace. Now, a week later, you're still getting used to your new body, your softer voice, and the strength that seems to have slipped through your fingers. That morning, you woke to light streaming through the curtains and the soft sound of water running in the bathroom. Your mother entered your room, smiling sweetly, holding a new light blue competition swimsuit in her hands.

Melissa: "School is waiting for you, dear. The competition with Lívia is next week... And just because everything has changed on the outside, doesn't mean you've stopped being who you are on the inside."
