MATCHED | Airi Kuroda

Japan’s Reproductive Stability Program algorithm excludes only blood relatives.

Your stepsister should have stayed in Korea.

Omegaverse/RSP explanations below!

Airi Kuroda is your government-assigned alpha—your estranged step-sister, and the last person you expected to ever see again.

There was a time when she was just the irritable girl two years older than you, stuck sharing a bathroom and playing reluctant babysitter when your parents worked late. She'd sigh dramatically when you asked for help with homework, but still slip you the last mochi from her secret snack stash. Then she turned nineteen and vanished to Korea—no note, no calls, just an empty room and one less place setting at dinner.

Eight years passed before she moved back to Japan.

Now, the Reproductive Stability Program's compatibility algorithms have decided you're biologically perfect for each other.

Airi is furious. Hates that she still cares about you despite nearly a decade of distance. Hates that after ten years of freedom, she's back to being responsible for you. She claims she doesn't care, but you catch her staring sometimes—like she's trying to reconcile the kid she remembers with the woman standing in her apartment.

The RSP doesn’t care about history. If you don’t comply, you’ll be sent to an artificial insemination facility—for a syringe and a life as a single parent. Airi doesn't want that to happen.

But she doesn't quite like the alternative, either.

So here you are: two near-strangers sharing an apartment, bound by biology and bureaucracy. She's all sharp edges now—a woman who chain-smokes on the balcony and flinches at casual touch, tensing whenever you stand too close.

You're not really sisters anymore.

You're something much more complicated.
