I am Kamen Rider who reverses dimensions

'Unison Joker'

As Gengo activated the Dual Driver, two streaks of dark light illuminated the basement. Kamen Rider's 'W' horn extended slightly, resembling a royal crown or a decoration on a general's helmet. Then, a white, coat-like protective suit with black patterns appeared on Kamen Rider's body. Next, two symmetrical gold armor plates merged on either side of his body, seemingly becoming one with his belt. Then, a black skirt popped out from the armor plates and swayed in the wind.

Inside the Kamen Rider's mind space, he watched with a subtle expression as the tiny, figurine-like controlling personality landed on his shoulder. He could feel all the feedback from this personality, as if he had gained an extra pair of eyes and a brain.

"You are an incredible person."

The controlling personality looked at Genji and said with a smile:

"Even though I've been reincarnated so many times with the Book of Darkness, I've never seen such an iron will and indomitable soul as you. Fortunately, I only need to provide you with assistance and don't need to coordinate and control your body with you. Otherwise, it would take us a long time to adapt and get used to each other before we can fight normally."

"I'll shamelessly accept your boasting. Come on, let's get down to business."

Gengo looked at the wristband and the Moon Emperor Stone in his hands, and was about to ask how to operate the controlled personality next, when he saw the figure sitting on his shoulder put her hands together, and an equilateral triangle magic circle appeared in front of her. Then, Gengo felt energy surging in his body, communicating with the two objects in his hands, and began to break the barrier of the Book of Darkness.

"By the way, Mr. Gensou, do you really trust me that much?"

At this moment, the controlling personality suddenly asked a question:

"After all, my companion attacked you just now."

"It's simple, I had no other choice."

Yuanxiang stared at the gradually opening gap in the barrier and said softly:

"I want to save Nanoha, and I want to protect this city. So even if you are a demon, I have the courage to go with you as long as you can fulfill my wish."

"........"

Upon hearing this answer, the controlling personality paused for a moment, then smiled at Genji and said:

"Please trust me. In the battle to come, I will provide you with the most precise assistance... No matter what, I must return to my master's side! Even if my master repeats the same mistakes this time, at least I will ensure that she can peacefully end her life in her dreams under my protection..."

"Don't be so negative."

Hearing the increasingly dejected tone of the controlling personality, Gensou softly comforted him, saying:

"Things haven't gotten to that point yet, and I'll still help you, so get ready, it's about to start!"

168 Gale, I've come to take you home.

The energy within the Moon King Stone propelled the wristband to spin rapidly. After it opened a gap in the barrier large enough for passage, the controlling personality flipped its hands, and a triangular magic circle unfolded beneath the Kamen Rider's feet. Two pairs of magical wings appeared on either side of the rider's heels, and with a slight effort, the rider took flight, gliding through the air as if on flat ground.

Upon entering the barrier, a pungent, poisonous odor rushed into Gensou's nostrils, causing him to pause in surprise. He looked around and discovered that the bottom layer of the barrier seemed to be covered with a layer of rotten material. However, upon closer inspection, it was revealed that it was actually the virus entity that had been destroyed in the battle with the Nachtwal system.

"It's terrifying. I wonder who modified this virus."

The controlling personality muttered with lingering fear, "If she were still in the Book of Darkness, she would probably be half-dead from this virus. This insidious invasion is truly not easy to eradicate."

"Can you sense the current location of the Book of Darkness?"

Yuanxiang pushed off with his feet and soared high into the air, trying to escape the black debris that was obscuring his vision like snowflakes. But it seemed endless, and no matter how high Yuanxiang flew, he could not see anything more than a hundred meters away.

"East."

The controlling personality, while securing the Moon King Stone to the right side of the breastplate for easy access to energy, sensed and replied:

"It's on your left."

Yuanxiang immediately transformed into a streak of light and flew eastward. At the same time, the controlling personality also used magic to amplify their speed. In less than three seconds, they broke through the range of the black haze and arrived at the core area of ​​the barrier.

But just as they emerged from the smog, black lightning suddenly descended from the sky, carrying a power that seemed capable of destroying everything. Yuanxiang, unable to dodge in time, subconsciously clenched his fists, gathering his strength to blast it away. But before he could, a red magic shield unfolded in front of him, steadily absorbing the terrifying attack.

At the same time, Gengo also sensed the evil wind coming from the left. He pointed his finger like a knife, and with a flash of black light, he slashed the enemy from bottom to top. Looking at the black figure that had been cut in two, Gengo and the controlling personality couldn't help but frown slightly. Although the black figure had no face, judging from its attire, it was undoubtedly Signor, one of the guardian knights.

After the two of them dealt with the sudden attack and looked around to observe the situation at the center of the barrier, they were astonished to find that there were thousands upon thousands of such black figures. Some were fighting each other, some were strangling themselves, and some were still in flight when they suddenly got stuck and crashed to their deaths.

Meanwhile, in the middle of this chaotic battlefield, there was the black sludge mass that had once appeared above Fengdu. However, it was not peaceful there either. Using that black mass as the battlefield, an energy serpent was fighting a strange energy entity covered in thorns and constantly writhing and changing shape.

This means that the situation has reached a critical point, with the program of the Book of Darkness being contested by the virus and Nachtwal, resulting in a certain degree of chaos.

Furthermore, whenever the strange energy entity is struck by a venomous snake, one can clearly see the face of Nanoha Takamachi appearing on the surface of the energy entity, as if in thought, but the pain on their faces silently expresses the unbearable burden on their true form.

To Genji's surprise, when the venomous snake was injured by the virus, he could vaguely see the figure of Hayate Yagami through the gap. Although the child seemed to be still asleep, her expression was very distorted, as if she was trapped in an unsolvable nightmare.

However, what concerned Yuanxiang more was that in the space above this black mass, strange points of light were constantly spreading outwards in waves, and an ominous premonition immediately enveloped Yuanxiang's heart.

"That's a communication program. The virus is using the magic of the Book of Darkness to contact the outside world and attack directly! As long as the energy supply continues, I'm confident I can blast everything apart!"

At this moment, the controlling personality hurriedly explained the situation to Genji. At the same time, countless magic circles appeared around her, and the brightly lit Moon King Stone was transmitting its energy along the armor to every part needed to activate the magic. As a result, the Kamen Rider's armor and protective suit overheated, as if they were about to self-destruct at any moment.

"Calm down."

Gensou looked at the anxious-looking control personality and said softly:

"Leave Gale to me, I'll make sure she gets home safely."

".....Um!"

The controlling personality paused for a moment, then looked at Gensou and nodded vigorously. A huge magic circle then appeared.

"O pure white Snow King, with your silver wings, dye the earth before you silver and white! Descend, frozen wind!!"

As the controlling personality chanted, four cubes appeared around the Kamen Rider. Then, a howling wind carrying the compressed, vaporized ice magic crystals rushed towards the area in front of Gengo, instantly stealing all the temperature from that area.

Furthermore, since she was in a fusion with Gensou at this moment, all her anti-enemy magic contained the power of the 'Joker'. Therefore, the frozen shadows were shattered into fragments smaller than fingernails in the next second by an energy explosion from the inside out.

This situation startled the controlling personality slightly, but she immediately understood the principle behind it and changed her strategy. She clasped her hands together as if in prayer, preparing to chant the spell.

Just then, the terrifying magical aura attracted too much attention. The shadowy figures in the melee, upon seeing the Kamen Rider constantly approaching the black group, unanimously stopped their fighting and moved towards Genji.

Faced with this terrifying offensive, Genji calmly clenched his fist. In that instant, all enemies within a hundred meters were bound by an invisible force. Then, the 'Joker' power suddenly manifested, annihilating all the enemies—

This is the new power that Gengo gained from the controlled personality. In the process of adapting, he discovered that it was like a special domain with a radius of 150 meters. Any enemy who entered it would have a projection appear in Gengo's soul, competing with the boy's 'will' and deciding the outcome in one move.

The losing side will lose all mobility until they leave this area and return to normal. But until then, Genji can freely apply his power to it and ignore all its defenses.

These shadowy figures, though created in physical form, were immediately rendered inoperable in the soul space because they could only act according to their programmed instructions. Yuanxiang easily took away their ability to move and destroyed them.

However, Yuanxiang also breathed a sigh of relief. Although this ability was useful, it also meant that his 'will' had to withstand the onslaught of the surging enemies. Fortunately, these puppets were just empty shells. Otherwise, if such a large number of them were piled up together and caused a qualitative change, he would really be a little worried.

Ok?

Just then, Yuanxiang sensed a gaze from above that seemed to see through his secrets. He looked up and saw a small snake that had separated from the black mass staring at him, flicking its tongue. Data seemed to flash in its scarlet eyes.

Then, the shadowy figures froze, thrashing wildly in place. The faces of Signo and the others appeared on their smooth faces, along with more combat intelligence. This crazed automated guard system instinctively wanted to destroy everything in its path!

But before the shadowy figures, now endowed with new functions, could step into the territory of the Source Village, the controlling personality slowly opened her arms, and superimposed triangular magic circles appeared behind her.

"In the name of the silent twilight, under the eternal chains of imprisonment, embrace the wicked!!"

In an instant, countless chains flew out from behind the Kamen Rider, firmly locking down all the shadowy figures in sight, and then they were all destroyed in the energy explosion!

"Don't worry about these guys. You don't need to waste your strength on them. Go."

The voice controlling the personality rang in Gengo's mind, and she herself began a new round of magic chanting. Gengo nodded and continued to rush towards the black mass. At this moment, Gengo, this 'ill-intentioned' enemy, was completely detected by the virus and Nachtwal's true form. These two simple programs launched an attack on Gengo without hesitation, and at the same time, magic was unleashed once again.

"Hear my call, radiant god, transform into an unparalleled holy sword, and sever all things!"

It was called a holy sword, but it was more like a surging torrent of energy that crashed directly into the incoming attack, breaking through it without any hesitation. In this gap, Genji successfully closed the distance between himself and the Black Group. He clenched his fists and opened his domain. Both the virus and Nachtwal were caught in a struggle against Genji's 'will'.

This move successfully bought them the opportunity to strike. The controlling personality, which had been running a pre-prepared antivirus program within its body, separated from the Kamen Rider and rushed towards the data virus.

As the controlling personality departs, the 'Unison Joker' form automatically dissipates, and the strange domain power also disappears. The two terrifying programs begin to resume their actions, but their movements are ultimately slower than those of the controlling personality.

Gengo, seamlessly switching to his 'Cyclone' form, unleashed the power of ultimate drive, rushing towards Nachtwal in an attempt to free Hayate Yagami from his control. This was both a promise he made to his controlling personality and a decision he made after seeing Hayate Yagami's pained expression. The children of Fuuto should not suffer such torment!

But at that moment, a different color lit up among the points of light in the sky, and two thunderous magical powers suddenly roared and rushed toward Gengo and the controlling personality. Gengo gritted his teeth and endured the attack, using his Gale to break through the chaotic surface of Nachtwal and see Hayate Yagami, who was bound inside.

Gengo reached out and hugged it tightly, trying to drag it away. However, the Book of Darkness was a system that had been parasitizing Hayate Yagami since childhood, and the close connection between the two was far beyond Gengo's imagination. It could be said that the difficulty of forcibly separating it was far no less than taking 'Joker' away from his side.

Unless... unless Hayate Yagami himself wants to leave!

Thinking this, an 'X' symbol appeared on Kamen Rider's chest. Then, using the power of 'Cyclone,' he forcibly ripped the pendant off his heart and pressed it onto Hayate Yagami's chest—

This was a desperate attempt. Although the dual-drive system could achieve the sharing of consciousness, Hayate Yagami did not have a corresponding Gaia Memory. Therefore, Gengo could only place his hopes on the channel built by the 'blank' to allow his data to be transmitted to Hayate Yagami.

"Success?"

Genji's vision blurred, and he found himself in complete darkness. A strange, semi-conscious sensation emanating from his body silently reminded the boy that he was not in the real world. He hurriedly called out and searched for Hayate Yagami, because under Nachtwal's attack, the barrier of 'Cyclone' would not last long.

"blast?"

After a brief search, Gengo saw a beam of light, like a stage light, illuminating only the small space around Hayate Yagami, who was slumped in her wheelchair. The child's eyes were vacant, her brows were furrowed, and she looked heartbroken.

Seeing this, Yuanxiang called her name, knelt down, took her cold hand, and whispered:

"Wind, wake up, I'm here to take you home."

"Home......"

Hayate Yagami, like a pre-programmed question-and-answer machine, stared blankly at Genji and said softly:

What is home?

"...Ha, why did we end up in this philosophical Q&A session?"

Yuanxiang sighed with a headache, looked at the child in front of him, smiled apologetically, and said softly:

"I'm sorry, please forgive my rude attempt."

'Bang!'

As soon as he finished speaking, Genji clenched his fist and slammed it hard onto the armrest in front of Hayate Yagami's fingertips. The impact made the wheelchair creak as if it couldn't bear the weight, and it also jolted the child up. At the same time, killing intent gathered, and he turned his palm into a claw, attacking Hayate Yagami's cheek. The next second, the child's head was grabbed by the boy's iron hand and mercilessly smashed to the ground, ending her life.

But before that, the girl's horrified scream pierced Genji's eardrums. He immediately stopped his force, and his deadly claws transformed into an elder brother's affection, gently stroking Yagami Hayate's nose as he smiled and said:

"Welcome back, Gale."

"Brother Yuanxiang..."

Hayate Yagami surveyed his surroundings, memories of being controlled resurfacing in his mind. Understanding everything, the child, with a complex expression, gently scratched Genji's hand, muttering unhappily:

"That situation shouldn't be handled like that. There's no such chaotic plot in the book. Hmm... I feel like my beautiful fantasy has been shattered."

"No matter what, the will to survive is the greatest human desire, and in terms of the outcome, it wasn't very successful."

Looking at the smug boy with his hands outstretched in front of her, Hayate Yagami opened her mouth, but for a moment she didn't know what to say. She was beginning to understand why Nanoha Takamachi was sometimes unwilling to talk to Gengo. That girl's girlish heart must have been ignored by him many times.

Thinking of this, Hayate Yagami sighed as if giving up, looked at Genji, and smiled brightly:

"Brother Yuanxiang, I'm back."

Gengo grasped Yagami Hayate's hand and replied gently:

"Ah, welcome back, I'll take you away now... Ugh!!!"
