Birdy trades the spy thriller setup for pure comedy chaos, and it works because the show trusts you to care about Tsutomu's hopeless crush enough to wreck everything for a laugh. A Federation marionette crashing a love confession is the kind of absurd escalation that only lands if you've watched the actual seasons, this OVA has zero interest in being a standalone entry. The energy shifts from "alien cop in a human's body" to "let's see how badly this can go," which is exactly where the character dynamics have been heading anyway.
Birdy finds herself playing matchmaker when Tsutomu needs help winning over Sayaka, enlisting her pin-up persona to orchestrate the perfect romantic setup. What starts as a straightforward plan to bring two people together spirals into chaos when a Federation-controlled marionette crashes the party with its own agenda. Caught between playing wingwoman and stopping an intergalactic threat, Birdy has to juggle her responsibilities as a Federation agent with her increasingly complicated friendship with Tsutomu. The OVA balances comedic romantic misunderstandings against sci-fi action sequences, creating a bridge between story arcs that shifts the dynamics between its main characters. There's genuine warmth here alongside the explosions and absurd situations, as Birdy grapples with how much she actually cares about Tsutomu's happiness. If you've been following the DECODE seasons, this fills crucial gaps while delivering exactly what the series does best: mixing superhero adventure with the awkward humor of secret identities and unrequited feelings.
