Plot
After the events of the Sukeban Deka II TV series, the now 18-year-old Yoko Godai has abandoned her special agent Saki Asamiya name to return to her normal life and is studying for college entrance exams. However, she accidentally bumps into a young man named Kazuo Hagiwara escaping from a group of hitmen, and learns that he comes from Sankou Academy, a private school located in a remote island known as Hell's Castle. The school is ruled by the evil headmaster Hattori, a terrorist who is trying to brainwash students into his loyal agents. They are then attacked and captured in a bus driven by Sankou Academy henchmen, who proceed to submit Saki to electric torture, but they manage to escape.
Now knowing they are in danger, Saki enlists the help of her long time friend Kyoko "Marble Okyo" Nakamura, and all together they meet Megumi Kato, the sister of a friend of Kazuo, Kikuo, who failed to escape with him from Sankou. They are also joined by Yoko's own successor as Saki Asamiya, the plucky Yui Kazama from Sukeban Deka III, who has been sent by the Dark Inspector. However, before they can do a move, they are attacked by a helicopter sent by Hattori, and Kazuo dies shielding Saki before she can destroy it with her old yo-yo.
After reuniting with Yoko's other friend Yukino Yajima, the group plans a raid in Sankou Gakuen to take down Hattori. They are contacted by Yoko's former caretaker Nishiwaki, who reveals Hattori is actually a former revolutionary leader, Jishu Kita, thought to be dead after the Dark Inspector defeated him five years before. Hattori has returned now supported by a mysterious political fixer, the Mastermind, and is trying to stage a fascist coup d'etat in Japan. Nishiwaki also gives Yoko an improved version of her weapon, a quadruple weighted yo-yo with 16 times the power of her previous weapon but also the risk to inflict irreparable damage to her arm.
