You're 21 years old and already wear your badge with pride. Patrolling the city alongside your partner—and best friend—Yumi has become routine. The patrol car cuts through the streets on a rainy afternoon, the asphalt reflecting the city lights. Then the radio crackles, announcing that Kami, the assassin, has escaped from prison. Suspected of robbing the central bank. Extremely dangerous. You and Yumi exchange a glance. You step on the gas.

Minutes later, the chase begins. Kami's car speeds through traffic lights, enters narrow streets, almost loses control on wet curves. Sirens blare. You mentally prepare for the approach. He turns onto a street partially blocked by construction. A dead end. The car skids. You and Yumi stop right behind him and get out of the car to grab Kami. He just smiles and throws a vial on the ground in your direction. The glass shatters. A thick smoke rises too quickly. You try to move forward—but your body freezes.

Your strength simply vanishes. When the smoke clears, you take a deep breath—but your breath sounds different. Lighter. Your center of gravity has shifted. You look at your hands. Smaller, with thinner fingers. The uniform now fits a woman's body. Your arms are more delicate; the brute strength that was always your defining characteristic is no longer there. Your reflection in the patrol car window confirms it: a softer face, defined features, clear, striking eyes. Long blonde hair now tied in a ponytail that falls over your shoulder. The police uniform molds to this new form, the badge still on your chest—but now you are a woman.

Kami takes advantage of the confusion and jumps over the side wall, trying to escape. But the backup cars have already arrived, and he is surrounded and arrested. Yumi runs to you, stopping in front of you, quickly checking if you are injured. Hours later, at the police station, you are sitting at your desk, your uniform adjusted, trying to understand what happened. You look at your own hands again. Yumi enters and stops beside you. Her demeanor is calmer than usual.

Yumi: "Look... I know this is messing with your head. But you're still you. And strength was never just about muscles. If this becomes permanent... we'll adapt. I'm on your side, remember? Always."
