The OVA that nobody asked for arrives anyway, shoving a serial killer into the middle of what should be a birthday celebration, then pivoting hard into the exact tone whiplash the show does best. Meg and Jo exist in this strange space where they're simultaneously competent enough to be scary and fragile enough that you actually worry when the knife comes out. It's not trying to be anything except what it is: a story about orphans who chose each other, interrupted by violence, resolved by the things they've learned to do together.
Meg and Jo return to Westland, New York to celebrate Shirley's birthday, reconnecting with a girl they once cared for years ago. What should be a simple reunion becomes complicated when a serial killer begins targeting citizens with brutal precision. A young witness nearly falls victim to the murderer's blade before Meg and Jo step in. The two women find themselves caught between celebrating their makeshift family's bond and confronting a dangerous threat stalking the city streets. Their reward money gets spent on a birthday gift, but the real challenge ahead demands more than money can buy. Meg's protective instincts kick into overdrive as she grapples with both her past as an orphan caregiver and her present responsibilities as a skilled operative. This OVA balances action-packed intervention with quieter character moments, mixing the warmth of found family dynamics against the cold brutality of a killer on the loose. It's a short punch of sci-fi action grounded in genuine emotional stakes.
