Thanks for the invitation. I'm in Type-Moon, inheriting the legacy of Zi-O.

"I'm sorry, Mashu, Ritsuka... and Mary." A hissing sound came through the earpiece. That guy must have cut off communication with Chaldea as well. Nian Zhuo showed a helpless but relieved smile. "Even if it's just for a few seconds, I hope to be ahead of you."

As their palms came together, the purple light shattered, forming the phantoms of three coins in the air, which were about to solidify and fall into Nian Zhuo's hands.

"Oh?" The other party had clearly noticed Nian Zhuo's actions as well, arms crossed, watching with relish. "A death wish? Hmm, not bad, not bad. Let's see how far you can go—"

Before he could finish speaking, the beast narrowed its eyes and turned to the side.

A purple flash passed in front of him and shot towards Nian Zhuo.

The phantom images of the three coins in mid-air were instantly struck by the purple light.

"Oh dear, what a pity, I missed that damn guy~" A playful voice came, and purple light fell in front of Nian Zhuo.

"You are—" As the figure slowly emerged from the purple light, Nian Zhuo's eyes widened, revealing an expression of disbelief. "How, could it be—?"

Then, gold, blue, and finally red light shot out from the same direction.

"Tsk, troublesome." With an impatient click of his tongue, the other party waved his hand, and several streams of dark light shot towards the strange-colored light.

However, the light dodged them all, striking the mountainside behind them and leaving behind a violent impact that shook the earth.

Then, the strange light gathered in front of Nian Zhuo.

Familiar figures emerged one by one from the light.

Momotaros, Rontaros, Putaros, Kintaros.

And then there was Ryotaro Nogami, walking slowly with a smile on his face.

"Yo, sorry to have kept you waiting, Nianzhuo." Smiling, Ryotaro adjusted his glasses, looking at the battered and bruised Nianzhuo, and shook his head. "It's amazing you managed to hold on for so long. Leave the rest to me."

"Hmph, he's just a mere Electric King, what can he possibly do?" With a disdainful snort, [Beast] suddenly jumped up from its spot and landed on a rock not far away.

The next moment, a pure white light fell on the spot where he had just been, creating a huge crater.

White feathers fell from the sky, landing on the tall figure within.

"Descending, poised to strike." Like a swan, the pure white alien god appeared in this space-time.

"...How could this be? You, who don't belong to this time and space, were also summoned here. How is this possible—" Finally, the other party showed surprise, but it was quickly concealed. "So that's how it is. You used the power of the time tram."

"You've managed to transfer your own power and companions from different times and spaces to this one. You're quite something, Ryotaro Nogami." Stroking his chin, [Beast] revealed a slightly serious look for the first time.

“You should call me senior, you rude guy.” In the distance, Sieg patted his spotless feathers, as if worried that the surrounding air would pollute him, and his eyes showed dissatisfaction. “Compared to you, I like that guy over there who has been looking grateful ever since we appeared more.”

"Hmph, is that so?" Without rebuttal, Nian Zhuo raised his hand and unleashed a purple ball of light, the power of Longtaros's bullet. "Then disappear."

"!" Next, countless feathers scattered, blocking the purple ball of light.

The feathers were scorched black, but the purple light only passed through them; Sieg, who had been standing there, had already disappeared.

"Truly, astonishing power." Then, it slowly descended from mid-air and landed in front of Momotaros and the others.

“Even if you summon me, I think your chances of winning are still…” Sieg glanced back at Ryotaro and the others, his azure eyes also showing little confidence.

"I'm...I'm sorry, Ryotaro." Nianzhuo rubbed his hands helplessly, looking at Ryotaro blocking his way. "My driver was destroyed by that guy, and now...I can't transform into a Kamen Rider anymore..."

"It's alright, we didn't intend for you to participate in this battle anyway," Ryotaro said nonchalantly, while giving Ryutaros a wink.

"Hey hey~ Come on, Nianzhuo, catch!" Longtaros nodded immediately and threw the purple light in his hand to Nianzhuo.

"This is—my previous trial card?" He quickly took it, and only after opening his hand did Nianzhuo realize it was a familiar warm current of power—the very same dinosaur combo trial card he had wanted to use not long ago. "Should I use it now...? But given my current physical condition, I'm not sure I can control it..."

“No, I mean you should take it.” Ryotaro patted Nencho’s head, his gaze gradually deepening. “After all, you have other tasks to do.”

"Another... mission?" Nian Zhuo asked, puzzled. Then, a blue light shone from the side.

"Oh dear~ I'm sorry, Nencho." It was Urtaros who used his fishing rod-shaped weapon to bind Nencho layer by layer.

Nian Zhuo, who is not currently transforming, is completely unable to resist.

"Wait, what are you doing! Ryotaro!" Struggling to break free from the ropes, Nencho shook his body as he looked at Ryotaro.

“Your mission is to survive, Nianzhuo.” Ryotaro’s gaze softened as he gently tapped Nianzhuo’s forehead with his index finger. “Only in this way can you, can you win.”

He forcefully pushed the bound thoughts backward.

Hmm—the hum of a tram came from behind, a rift in space opened, and the Time Train slowly pulled out.

They stopped behind Nianzhuo and opened the car door just before Nianzhuo collapsed.

"Oh~ so heavy." Then, a mature and deep male voice came from the train conductor, who was dressed in a suit and tie, as he caught Nian Zhuo, who was tied up, and dragged him onto the tram.

“…Momotaros.” Ryotaro, with his back to the Imagin, gave a wink to his most trusted companion.

"Oh!" came the enthusiastic response.

Momotaros brandished her sword, severing the chains binding Mash, Ritsuka, and Mordred. Carrying them one by one in each hand and another on her shoulder, she lifted them all onto the train.

"Is this alright, Ryotaro?" Patting Ryotaro on the shoulder, the Imagin turned around and looked at Mash and Ritsuka, who, although they had exhausted themselves struggling, were still trying to get up.

He bent down.

"Thank you for taking care of us during this time!" they said in unison.

"Wait, Ryotaro...you wouldn't be thinking of...!" Nencho struggled, bound and glancing at Ryotaro smiling outside the car window, and at the Immortals who stood up straight with complicated smiles on their faces. "No! I absolutely cannot agree!"

Struggling, Nian Zhuo rolled to the ground, trying to control his body to get out.

"Close the door, Commander," Ryotaro said slowly.

"...Hmm." Without needing to ask any further questions, the train commander nodded.

The bright red car door slowly closed, blocking Nianzhuo and Liangtaro.

"No...no..." Nian Zhuo felt the pain aggravate the wound on his chest, but he still wanted to get closer and open that annoying car door.

"Alright, Nianzhuo." Ryotaro's voice came from the other end of the car door, as gentle as ever, but now sounded so grating to Nianzhuo's ears.

"Listen up, Nianzhuo." His gaze was fixed on Nianzhuo, who was shaking his head desperately, and the Den-O Driver was already on his waist.

"One day, you will take back your future with your own hands."

"One day, you will prove that you are on the right path."

"One day, we will meet again somewhere else."

"So, before that, never be confused, Nen-cho." A bright red, cell phone-like device appeared in his hand. Ryotaro pressed 3, 6, 9, * and the call button, and placed it on the driver at his waist.

Behind him, Momotaros, Urataros, Kintaros, Ryutaros, and Sieg gradually transformed into various colored lights, converging on Ryotaro's body.

"Now, it's time to say goodbye, Nianzhuo." He slowly turned his back, his figure gradually changing.

Kamen Rider Den-O's strongest form, Super Pinnacle Form, transformation complete.

"—Go!!" Ryotaro's final shout came as the long time train behind him opened a gap in space and slowly drove away from this deadly place.

"And then?" In the distance, the [Beast], arms crossed, witnessed everything but didn't interfere. "You're the only one left? Trying to buy them time?"

The other person just chuckled and gently rotated their hand.

A dark golden clock appeared above Den-O's Super Climax form and suddenly fell.

"—Pfft!" Before he could even react, Ryotaro's body was suddenly pressed down.

Countless cracks appeared on its body.

"...They actually withstood it." The smile gradually faded from the beast's face as he clapped his hands.

"Not bad, like a warrior." The surrounding black and gold light gathered at his waist, forming the shape of a time-space driver.

"As a response to your determination to die, I will not pursue them until you are dead. Be happy." Without even needing a watch face, [Beast] merely moved its mind, and the jet-black Zi-O armor was equipped on the other party in the next moment.

"Then, how long can you hold on?"

Ryotaro drew his Electric Masked Sword and launched an attack on his opponent.

"Super Boisterous Slash—!!" He unleashed his strongest finishing move right from the start, because Ryotaro knew that the opponent's power was something he couldn't withstand in his current state, so he could only unleash as many attacks as possible to create more time for Nencho and the others.

Faced with the sword blade crackling with electricity, the other party simply stretched out their hand.

The violent roar shook the entire underground land.

As the smoke cleared, the two knights stood facing each other.

However, the black Zi-O raised his hand, and the bright red blood on it seemed to have just gushed out.

"Two minutes, that's your limit." Behind him, Den-O's Super Pinnacle form suddenly collapsed to the ground.

All the red, blue, gold, purple, and even white light on his body turned into ashes.

In order to buy more time, each of the Otherworldly Gods used their own lives to block the opponent's fatal blow, and they died without uttering a single complaint.

"Was it worth it?" As Den-O's armor gradually disappeared, revealing Ryotaro's battered and dying body, [Beast] couldn't help but ask, "Just for these mere two minutes, he sacrificed his life?"

"Hmph, of course it's worth it." The rise and fall of his chest gradually subsided, and Ryotaro looked at the bright moon in the sky, where a huge black bat seemed to flash by.

"I have... successfully passed on hope..."

After saying that, he closed his eyes forever and fell into a deep sleep.

“Is that so? I hope so…” Facing the dead Ryotaro, [Beast] reached out his hand.

"Then I will completely erase your history as Kamen Rider Den-O!"

A golden aura emanated from him and gradually spread throughout time and space.

The world related to Kamen Rider Den-O... everything is slowly disappearing.

"...Huh?!" In 2068, Oma Zi-O, gazing at her own statue, was astonished to see that the sculpture representing Den-O had developed black cracks!

"Hmph, I don't know who this power comes from, but you better tone it down!" With a single wave of his hand, the speed at which the black cracks spread suddenly slowed down and gradually stopped.

Miss Oma retracted her hand, looking at the small red... 'water droplet' in her palm.

"...This feeling..." As if she had guessed something, she slowly turned and left.

Aside from this unexpected time-space event, the fluctuations that erased everything about Kamen Rider Den-O continue to rage.

However, when the wave spread to the space-time where Nian Zhuo and the others were, two beams of light, one red and one blue, emerged from the azure Earth, offsetting the incoming wave.

"...So, you owe us a favor, Nianzhuo." The two girls in Western-style dresses looked at the azure planet behind them and moved their slightly cracked hands behind their backs.

The knight named Den-O has completely disappeared.

Having traversed time and space, the Time Train finally reopened its passage in the control room of Chaldea.
