Time Demon Chronos, Bunko Ogata, and High Priest Gajya hatch a plan to wipe out the Boukengers while seizing three Goodomu Engines, a scheme that casts a watchful, unseen figure over their machinations from above. The Boukengers, with the exception of Bouken Silver, are soon called into battle against a spreading Curse, and after a grueling clash they confront the sinister pair—Chronos and Gajya—who abruptly send the team into a different dimension. Mitsuomi Takahashi brings to life Satoru Akashi / Bouken Red, a key figure who appears as the plot thickens, while Eiji Takaoka / Bouken Silver, Masayuki Deai plays a pivotal, if tightening, role from the sidelines.
A mysterious figure named Aka Red, Toru Furuya, reveals a world of past and present Super Sentai warriors by gifting Eiji the Super Sentai Address Book, a relic that catalogs every Super Sentai member. This opens the door to introductions and reunions across episodes and eras: the first entry points to Magi Yellow, Hiroya Matsumoto as Tsubasa Ozu, followed by the undercover grit of Deka Break, Tomokazu Yoshida as Tetsu Aira, who is wrestling with his cover while aliens loom nearby. The narrative widens as Maij Yellow’s aura is felt through the address book, and the book’s pages begin to glow with echoes of old battles and new threats.
Back in the time-warped prison of Chronos’s devices, the Boukengers discover their technology blocked, and they reconnect with Hikaru, Yousuke Ichikawa the Magi Shine, who has his own ties to Magiranger’s legacy. A message from Satoru arrives, and a fragile alliance forms around the promise of rescue. The path toward rescue winds through a flurry of familiar faces: Eiji reaches out to Nanami Nono / Hurricane Blue, Nao Nagasawa as she rehearses, but is stopped by crowds and security—until a bold shout of her hero’s name breaks through and sparks a spark of recognition.
Chronos’s plan marches forward as he calls forth Meemy, a Magiranger adversary, to join his ranks, and Eiji, bruised but unbroken, tosses the Super Sentai Address Book aside in a bid to challenge the impossible on his own. Help arrives in force when Hurricane Blue, Abare Black, Deka Break, and Magi Yellow converge to pull him from the brink, though their coordination proves tricky and misaligned at times as the group tries to synchronize their long histories into one united front. In a hidden corner of Chronos’s time-prison, Satoru reveals that Zubaan is still within reach, and TsueTsue from Gaoranger is revived by Gajya’s hand, a grim reminder of the consequences of tampering with time.
At SGS, a crucial message from Satoru signals that Chronos’s scheme is nearing its climax, and the Super Sentai warriors pledge to join Eiji in a bid to rescue the rest of the Boukengers. The search leads toward Aka Red’s dimensional door, and the time-prison’s last hours begin to slip away. Chronos and the other villains close in, and the heroes race to prevent a catastrophe that would erase their world. Sakura Nishihori / Bouken Pink, Haruka Suenaga, analyses the structure of Chronos’s trap and deduces that a wall clock etched with root-like designs is the key to their escape. With time running out, the Boukengers and Hikaru face a looming collapse, and the team launches a last, desperate gambit.
Aka Red steps into the fray, transforming into Magi Red and Gao Red, rallying the remaining Sentai spirits as a vessel for power. The act of sacrifice and unity gives the team a glimmer of hope, as they unleash the Smoky Shining Attack with the assistance of Zubaan to pry open the clock and reveal a second root-clock in the real world. The mission shifts to destroying the clock, while Aka Red holds Chronos at bay, a daring gambit that turns the tide in favor of the heroes. With Magi Red and Gao Red driving back the villains, the Timelines converge as the Boukengers free the trapped Magi Shine and Eiji from the alternate dimension.
The battle erupts into a full-blown showdown between the Super Sentai coalition and Chronos’s forces, with the Sentai warriors gaining the upper hand only briefly before Furabiijo, from Ninpuu Sentai Hurricanger, Azusa Yamamoto interrupts the fray with a bold interruption that shakes the balance. With all three Sorcerers present, Chronos unites their power into the Staff of the Three Philosophers, fashioning a golden armor and growing to colossal size. The Boukengers deploy Ultimate DaiBouken and SirenBuilder, only to find Chronos too formidable to break through, and even the mighty DaiVoyager comes under threat.
In a decisive pivot, Aka Red returns in full, channeling the Spirits of the remaining Sentai warriors to empower DaiVoyager, and the team presses forward with a Burning Legend-powered assault. The climactic finish arrives when the Burning Legend DaiVoyager consumes the Soul energy of thirty past Sentai heroes in one spectacular burst, defeating Chronos and banishing the three sorcerers back to the afterlife. With Chronos defeated and the sorcerers returned to their respective paths, the Boukengers and their allies head back to SGS, their victory tempered by the realization that new threats lurk on the horizon—the Negative Syndicate remains active, and a fresh call from Mr. Voice, Nobuo Tanaka, hints that danger is far from over.
As the screen fades, Aka Red watches the Earth from space, drifting into a quiet sleep until the moment he is needed again, leaving a final echo of hope that the Super Sentai legacy will endure and continue to unite, across dimensions and generations, against whatever darkness may come.
