The Sento team, having escaped through the collapsing time-space channel, made one final use of the damaged Time Demon Machine. Without hesitation, they rammed it straight into Tid's base—completely disregarding the fact that Hisunaga Shingo was still inside.
Fortunately, the base was built with reinforced structure. The crash only shattered part of the wall, punching an excellent entry hole.
While Tsukuyomi stayed behind to assess whether the wrecked Time Demon Machine could be salvaged, Sento, Gates, and Fengtaros charged into the enemy stronghold and confronted Tid directly.
"How did you come back?!" Tid's face twisted in disbelief as he saw them.
"Who knows?" Sento replied with a smirk. "Maybe someone decided to give us a hand."
"Hmph! Doesn't matter!" Tid scoffed, rushing over to the energy cage imprisoning Shingo Hisunaga. "I've already sealed the singularity! Very soon, both you and the entire history of Kamen Riders will vanish from this world!"
"Then we'll defeat you before that happens!" Sento didn't waste another word. He began to activate his transformation.
Tid had made a critical mistake—he assumed they were mere memories or data echoes that could vanish along with the timeline. But Sento, Gates, and Fengtaros were physically present. Even if the Rider history of this world was erased, it wouldn't affect their real bodies.
Still, Tid remained dangerous. As the only person who understood how to manipulate the Time Demon Machine's technology, he took advantage of the moment and summoned a transformed version of Kamen Rider Den-O—the monstrous Another Den-O—alongside a horde of soldiers.
Unable to complete their transformation in time, Sento, Gates, and Fengtaros were quickly overwhelmed. The Another Den-O raised its weapon to deal the finishing blow—
—when a blinding light engulfed the area. In the next instant, everyone—except Tid—was gone.
Inside the suspended world of the time-train's terminal station, two groups were thrown unceremoniously onto the floor.
"Huh? Where are we?!" The two sides looked around in confusion.
Suddenly, a foot launched into view and kicked Another Den-O squarely in the rear, sending him tumbling.
"My name is... wait! I'm facing the wrong way!"
A flamboyant figure struck a dramatic pose with his back to the enemy—only to awkwardly realize his mistake. He quickly spun around and repeated his entrance.
"My name is... Den-O! I have arrived!"
The true Kamen Rider Den-O, in his Sword Form—Momotaros in control—flashed a wild grin.
"Yo! You look just like me... but you're way weaker!"
"That was a cheap shot!" Another Den-O growled, struggling to stand.
"Don't care!" Momotaros jeered, casually dodging incoming soldier attacks. He assembled his DenGasher into its sword configuration.
"Listen up! I don't need preparation. From start to finish, I fight at full throttle!"
With gleeful fury, Momotaros charged into the enemy lines, mowing down soldiers in a sweeping, unrelenting assault.
Just as he was beginning to enjoy himself, a familiar chaos erupted.
"Tao! You've hogged the spotlight long enough!"
A golden energy form burst forth—Kintaros—slamming into Den-O's body and taking control, ejecting Momotaros in the process.
[Ax Form!]
"You stinkin' bear!" Momotaros shouted, watching Den-O morph into his Axe Form.
"Cry... for my strength!" Kintaros roared, cleaving the Another Den-O with a massive overhead swing of his DenGasher in axe mode.
Then—
[Gun Form!]
Before Kintaros could deliver the follow-up, he was ejected by Ryutaros, turning Den-O into his Gun Form.
"Can I beat you? Doesn't matter what you think!" Ryutaros fired a barrage of bullets at Another Den-O without hesitation.
"Ryutaros! Behind you!"
"Where?!" The moment he turned around, he lost control of the body to yet another rider—
[Rod Form!]
"Oh come on! Classic bait-and-switch!" Ryutaros groaned as Urataros took over.
"Let's see if you fall for this hook!" Urataros chuckled, spinning the DenGasher in rod mode like a fishing pole. With a flick, he pierced Another Den-O and pinned him in place.
With his target immobilized, Den-O delivered a finishing Rider Kick, sending Another Den-O flying and exploding in a brilliant flash. The imprisoned Shingo Hisunaga was safely ejected in the aftermath.
"You okay?" Urataros de-transformed, but Ryotaro Nogami's body remained upright as he supported Shingo.
"No way... you're Ryotaro Nogami!" Shingo's eyes lit up. As a devoted Rider fan, he recognized him instantly.
Just then, Sento, Gates, and Fengtaros—finally recovered—entered the room.
"Where are we?" Gates asked, scanning the train station.
"A different space-time from yours," Urataros explained casually.
"And you are...?" Sento asked.
"Kamen Rider Den-O. Time patrolman of love and justice!" Urataros gave a theatrical salute.
"Didn't you say earlier that Kamen Riders don't exist anymore?" Urataros turned to Shingo.
"Well... I..."
Urataros grinned knowingly. "Even if we were born from fiction, as long as someone remembers us, Kamen Riders become real. In the dimension of memory, we always exist."
Such is the Rider universe—idealistic, and governed by the belief that remembrance alone sustains existence.
"Yeah!" Shingo nodded, eyes shining.
"The Kamen Rider Den-O of love and justice? I'll remember that!" Sento exclaimed.
"Then I'll leave it to you." Urataros smiled. With a shimmer of light, Sento and his team were teleported back to Tid's base.
Tid blinked.
"...What the—?"
He stood in stunned silence, staring at the three intruders now casually reappearing.
"How... how are you back AGAIN?! You're fiction! You shouldn't exist!" Tid screamed, his hysteria mounting.
"But we do." Shingo stepped forward, his voice calm and resolute. "I used to believe Kamen Riders weren't real. But I was wrong."
He clenched his fists.
"Because as long as someone remembers... Kamen Riders will never disappear!"
"That's right!" Sento activated his Ziku Driver.
[Zi-O!]
"We exist. Right now. Right here!"
Elsewhere, Ryuga, watching from the shadows, sensed over a dozen Rider energy signatures suddenly materializing across the city.
He grinned. "Perfect timing." After ensuring Ora was safe, he darted through the city with purpose.
Sento may be focused on saving people, but I'm under no such restrictions. I don't have a writer limiting my growth like in a movie spin-off. Time to reap everything I can.
Even if it's just the main Riders... it's still an unprecedented haul.
There's no rule saying a Rider's power can only be collected once. With every retrieval, I grow stronger. Bit by bit, I'll gather them all.
