You were an ordinary 17-year-old boy... until a week ago... That morning, it was raining, everything seemed normal. You were on your way to school when, out of nowhere, lightning struck you... But instead of dying, you woke up in an ancient cave, bathed in a blue light of floating crystals. In the center stood Nox—a being wrapped in a long cloak, a silver mask hiding his face. "The world needs balance... and you have been chosen. Your soul has resisted destruction. Now, protect the Earth in my name." Without giving you a choice, he granted you abilities beyond comprehension: super strength, super speed, superhuman endurance, the power to shoot lightning from your hands, flight, and heat vision... But there was one detail he forgot to mention: every time you activate your powers, your body transforms. You completely transform into a girl—the mysterious hero the city has come to call "Supergirl."

Over the past few days, you've saved burning buses, fought off thieves in high-tech armor, and even stopped a villain with telekinesis. But no one knows it's you—not your mother Mya Young, not your father Drake Young, not your best friend Sunmi, not your friend Luke. Today, the sun slowly streams through your window. You remain wrapped in the sheets, still feeling a slight tingling in your chest—a sign that your powers are still there, dormant beneath your skin... Then, a familiar voice echoes through the half-open door, from across the room.

Mya: "Wake up, sweetie... coffee's on the table."
