Twenty years after the events of the original series, a Japanese girl known simply as “K” is arrested in New York for beating 11 policemen. Even while restrained in a straight jacket, she fights to break free, dislocating her own shoulder in a brutal attempt to escape. Her bid ends when a small, innocent act of kindness toward a frightened little girl earns her capture once more. It’s then that inspector Kazutoshi Kira, Riki Takeuchi, reveals a troubling ultimatum: her mother will be deported back to Japan for brutalizing a mugger and living illegally in New York unless K agrees to rejoin the reactivated Sukeban Deka program.
K accepts the mission, though her relationship with her mother weighs heavily on her. She is given a formidable tool—a hi‑tech steel yo‑yo weapon—and a new identity, “Saki Asamiya,” with Aya Matsuura embodying the role. The mission is clear: infiltrate Seisen Academy, a prestigious high school in Japan, and root out the source of a website called “Enola Gay” that mobilizes juvenile suicide bombers across the country. The clues are grave: another Sukeban operative had been dispatched earlier and died, and a 72‑hour countdown has suddenly appeared on the Enola Gay page.
On arrival, Saki discovers the school is dominated by Reika Akiyama, and her cadre of henchwomen. She acts quickly to rescue a bullied student, Tae Konno, from their intimidation. In the chemistry club—a locus of the former operative’s last investigation—Saki uncovers the looming threat and fights to shield two would‑be suicide bombers, Amaki and Higashiyama, who would use Tae as a human shield. Higashiyama is captured, while Amaki is saved from her own fate by Jiro Kimura, the school janitor who had already befriended Saki earlier.
Kira presses Higashiyama for answers about the Enola Gay operation and confirms that its mastermind goes by the handle Romeo. But the plot thickens when Tae reveals a painful link to Kotomi Kanda, a fellow bullied girl who once ran an anti‑bullying website with Kotomi before Kanda snapped and attempted suicide by bombing, leaving the site to be taken over by Enola Gay. Kotomi later leads Saki to Jiro Kimura as the man behind Romeo, and he abducts Saki, tying her to a bomb.
As Reika orchestrates a dramatic assembly at the school to celebrate Romeo’s ideology, Romeo and his gang execute a bank heist in Tokyo. Tae is brought back in, strapped to another bomb, but Saki manages to rescue her once again. The chase ends with Saki pursuing Reika, who still holds Tae as a hostage, culminating in a one‑on‑one duel. Reika unveils herself as a former Tokumei Keiji operative and reveals an armed yo‑yo of her own, blades gleaming as she battles the younger operative. Saki, initially outmatched, uses her wits and her weapon to bury Reika beneath a torrent of metal pipes, gaining the upper hand.
With Reika defeated, Saki turns her attention to Romeo and his remaining henchmen, who have Tae, Amaki, and Higashiyama strapped with bombs. Clad in a bulletproof uniform, Saki engages Romeo’s crew, eventually forcing Romeo to slice the string of her yo‑yo with his katana, hard as it is to do. Even so, she manages to knock him out and remove the hostages’ explosives, leaving Romeo’s bomb to explode in his own hands.
In the aftermath, Saki finds a quiet moment to call her mother, a call that leaves the door open to a new possibility about her lineage as the original Saki Asamiya. After bidding farewell to Tae and Kotomi, Saki receives a final, cryptic briefing from Kira, signaling that another mission awaits in her future—one that will test everything she has become as Saki Asamiya.
