Zi-O is in the world of Kamen Rider Build

"They are Oyama Masaru (red feather), Aikawa Shuya (blue feather), and Mihara Seikichi (yellow feather)."

"It turns out it's them."

As he was thinking, Yi Hai suddenly understood something and sat up from the ground. He, who was originally drowsy, became alert now.

"You mean that in the future you foresee, the three of them will die?"

"bingo!"

Afterwards, Sougo recounted the general plot of "Kamen Rider Build".

But there is no need to explain too much, after all, many of the plots are things Yi Hai has experienced personally.

From the time Yi Hai took the initiative to join Beidu's human experiment, until he encountered the Three Crows mimicked by the snake-skin monster while climbing the [Pandora's Tower], Yi Hai was so stimulated that his heart was completely broken, and he used the [Blizzard Gloves] and the mimicked [Three Crows] to die together.

"Well, it's really my style to act cool in front of [Mi Tan] until the very end!"

"But you seem to be hiding something."

It should be said that Yi Hai is worthy of being the intellectual leader among the "Three Idiots". He noticed something wrong in the story told by Sougo.

"What about you?"

"This is the story that would have happened in a timeline without me."

"The ending obviously looks like... a happy ending."

Regarding the matter of [Fusion of Parallel Worlds], Yi Hai was not sure whether it was good or bad, and could only describe it with some vague lines.

"If that's the case, then there's no reason for you to get involved at all, right?"

"Have!"

When he mentioned the reason why he was fighting, Sougo couldn't help but clench his fists.

"Because in that new world, there is no place for my parents."

"Yeah." (Nods)

"What?" (confused)

"Ah!" (Suddenly realized)

"What are you talking about?"

"In this new world, a bastard from the future traveled through time when I was ten years old, killed my parents, and turned me into an orphan. If the [Parallel World Fusion] is completed, I will instantly go from having both parents alive to having both of them orphaned since childhood."

"..."

"This is also why I don't like Battle Rabbit. From now on, whether it's Katsuragi Takumi or Katsuragi Shinobu, if any of them dares to mention [Parallel World Fusion] in front of me, I will blow his head off!"

"no sooner said than done!"

"..."

Yi Hai fell into deep thought, trying to put himself in the other person's shoes and take in the perspectives of both sides.

If we look at it from the perspective of Sento, everyone in the world was going to die anyway, and he could only choose to save as many as he could. Even after the [Parallel World Fusion] was completed, he could not guarantee the consequences.

But if you look at it from Sougo's perspective, it was really an unexpected disaster, and Evolto's invincibility was inseparable from the help of Shinobu Katsuragi, Takumi Katsuragi, or the father and son Kiryu Sento.

In other words, it's one of those stupid stories where a mad scientist nearly destroys the Earth, but ends up having someone else take the blame.

Both sides have their own reasons and are in a position where they will never compromise with the other side.

so......

"But Evolto is dead!"

Yi Hai suddenly said.

The biggest problem in the later period of "Kamen Rider Build" is Evolto, who was sent out by the Battle Rabbit and his son and became fatter than ever. But the problem is that Evolto was strangled to death in the cradle by Sougo himself before he even grew up. So all the problems should have been solved.

"They won't continue to consider [Parallel World Fusion], right?"

Yi Hai asked tentatively, but received a sneer from Sougo.

“P!”

I remember that near the end of the story, Sento, Ryuga, Ikkai and Gentoku worked together and finally defeated the almost invincible Black Hole Snakeskin head-on, successfully adding a black star to its almost undefeated resume, although the Snakeskin monster was just faking its death.

Then, seeing that the snake-skinned monster was dead, Shinobu Katsuragi quickly jumped back and explained her plan about the [Fusion of Parallel Worlds]. However, before she could even finish half of her plan, she was caught in bed by the snake-skinned monster who had faked his death, and died on the spot.

From this we can see that even if there is no snake-skinned monster, Shinobu Katsuragi still insists on [Fusion of Parallel Worlds].

As evil scientists, many ordinary people died because of the human experiments conducted by this father and son.

Therefore, in order to save these people, and more importantly, to save the innocent people who died because of the [Wall of the Sky] ten years ago and all the people who died in the Sandu Civil War, Shinobu Katsuragi will definitely stick to his [Parallel World Fusion] plan.

Now that Evolto is dead, putting this reason aside, in the end, wouldn't it be Shinobu Katsuragi who sacrificed Sougo's parents to wash away the sins he had committed?

"grass!"

After Sougo's explanation, Yi Hai realized the root of the problem.

If we think more broadly, Sougo's parents are not an isolated case, but there are hundreds, thousands, even tens of thousands, hundreds of thousands of people who are the same and have no place in the new world. So once the [Parallel World Fusion] is completed...

This is really terrifying when you think about it!

so......

"Isn't this still Shinobu Katsuragi's fault after all?"

Regardless of the effect of [Parallel World Fusion], in the final analysis, it is still Shinobu Katsuragi’s own sin of abusing human experiments.

"So I hope that if that guy makes similar remarks, I hope you can help me! Stand firmly on my side!"

Sougo held Yi Hai's hands with a determined yet eager look, and there was a hint of crying in his voice, like a person who had suffered great injustice and bullying outside and was complaining to his parents.

"Really!"

Yi Hai couldn't help but curl his lips, and pulled Sougo into his arms, protecting him tightly, giving him warmth and a sense of security, which made Sougo couldn't help but recall the moment when Yi Hai used himself as a shield and risked his life to save him when Zhan Rabbit self-destructed.

"You are so grown up, but you still act like a child."

"He vowed to blow up the earth with one punch, but he ended up looking like he was about to cry."

"Actually, actually, actually..."

Seeing that Sougo was stuttering, Ikkai urged him:

"What is it actually?"

"You are now a man who can blow up a main battle tank with one punch. Stop nagging me. If you have something to say, say it now. If you have something to say, fart now!"

"In fact, I have always found it difficult to overcome my fear."

"Fear?"

"Yes."

Sougo showed a look of relief.

Saying out all the secrets that had been suppressed in his heart for years in one breath, this feeling is even more comfortable and satisfying than kicking Daguba to death, punching the black hole snake monster to death, and finally giving Swaruz a finishing knight kick to death.

"Ever since I foresaw the future when I was young and saw Evolto, which could destroy the earth, my heart has been filled with fear. Because if I want to protect my parents, I have to fight that star-eating monster."

"really."

Yi Hai nodded. "Even I may not have the courage to overcome my fear and face such an enemy. Unless..."

Unless their families and employees are threatened.

“Although I was trembling with fear and dared not take any action, I knew very well that if I didn’t do something, the predicted future would come true.”

"The timeline will change. My parents will die when I am ten years old, and I will become an orphan."

"So I need a motivation to help me overcome my fear."

"So you shifted the target of your hatred from Evolto to Kiryu Sento, Katsuragi Takumi and Katsuragi Shinobu?" Ikkai suddenly interrupted.

"......How did you know?"

At this moment, Sougo was like a child who made a New Year's wish for an expensive toy, but his parents saw through his wish and pointed it out on the spot.

"Silly son!"

"Don't you think about it? We've been together for five or six years. I know what kind of fart you're going to fart just by the way you stick your mouth out!"

Yi Hai hit Sougo with an elbow without any hesitation, and the pain was so severe that Sougo almost popped his eyes out.

"Hey!"

"Now we're even."

"Besides, you just talked about [Parallel World Fusion] for a long time. Even a fool knows that you have a lot of objections to this plan."

"But don't worry, even if that Katsuragi Shinobu says something terrible, I will still support you."

"Why should the sins he committed require you to make sacrifices?"

"In order to save others, some people have to be sacrificed, but in the end, nothing can be saved, right?"

"Besides, I don't like merging with another me. Who knows if I will still be the original me after the [Parallel World Fusion] is completed!"

The most important thing is that after the fusion, I may not be able to be with you again and spend such a wonderful journey with you.

Yi Hai didn't say the second half of the sentence, just like he was madly infatuated with [Mi Tan Jiang], but in the end, he didn't even have the courage to hold her hand.

"Thank you."

Sougo fell into a deep sleep, sinking into a baby-like sleep.

It was the first time in all these years that he slept so soundly.

There was another sentence that Yi Hai didn't say.

"Although you fought with your own selfish motives, in fact, you still succeeded in saving the lives of everyone in this world."

"Are you still not a Kamen Rider who fights to death for love and peace, and who fights to protect all mankind?"

"I am proud to have you as my son!"

Looking to the other side, Gentoku and Katsuragi Takumi were walking together on the ruins-filled streets of Toudou.

In the memories of the two, this area was once full of lights and wine, extremely prosperous, but now under the ravages of war, only ruins and devastation remain.

The war was started by Gentoku, and Katsuragi Takumi, as Gentoku's most capable demon scientist, is particularly to blame.

"I don't want to hear any excuses from you."

Watching all this, after realizing the sins he had committed, even someone as rational as Katsuragi Takumi's eyes became confused, and his voice was low. "You and I jointly caused this war, this tragedy. This is an undeniable, indisputable fact."

"I know. And I am willing to accept any sanctions and punishment for this."

Gentoku stopped and turned to look at Katsuragi Takumi with an extremely honest expression. "But this country has fallen apart, so I chose to fight in order to rebuild it."

In response, Katsuragi Takumi simply said:

"Now that Evolto is dead, the war continues. What's the point of admitting these mistakes now?"

Yes.

The war burned, homes were burned down, and countless ordinary people were involved and sacrificed their lives in vain.

Even if he admitted his guilt, the dead could not be saved. This was the sin of both him, Takumi Katsuragi and Gentoku.

"..."

There is no answer, or perhaps it can be said that Huande, an honest man, cannot give any inspirational words about the profound principles of life.

"I shouldn't have trusted you in the first place."

After leaving these words, Katsuragi Takumi turned and walked away, strolling among the ruins, leaving Gentoku alone there.

"What on earth have I been protecting?"

Katsuragi Takumi found a small corner and squatted there, falling into deep autism.

Unlike the original TV series, everyone has a star-eating monster named Evolto hanging over their heads, so Shinobu Katsuragi has no time to be autistic and has to devote himself to the development of the "Genius Bottle". Now he has plenty of time to be autistic.

At this moment, a familiar sound of footsteps approached, attracting Katsuragi Takumi's attention. He stood up sharply, alert to whether the person coming was a wild [Crusher].

However, unexpectedly, the visitor was a familiar face, wearing a white coat, with gray hair, a healthy body, and energetic eyes.

That is......

"Coincidentally, I'm back."
