I am Kamen Rider who reverses dimensions

hateful!

Just as Anhk clicked his tongue and was about to turn around to help Philip forcibly insert the memory into the drive, a strange noise suddenly came. Everyone subconsciously looked into the deepest part and found that azure flames, seemingly from nowhere, were mercilessly destroying the filthy kingdom. In the flickering light, the boy slowly straightened up. He slowly exhaled, and white mist drew rainbows in the firelight. He looked up at the dinosaur avatar, a glint of eerie blue flashing in his black eyes. The chilling aura forced the dinosaur avatar to take a step back and let out a threatening growl at the boy.

But Gensou didn't pay any attention to him. The boy simply fastened the dual-drive to his waist, and then a thick wisp of white smoke emerged from behind him, gathering on the boy's shoulder to form the shape of a model mechanical dinosaur, which let out a deafening roar that was completely disproportionate to its size. At the same time, Philip and the others were also stunned when they saw this, because the dinosaur looked very similar to 'Fang' next to them.

But Gensou's 'Fang' didn't give them much time to distinguish the differences. After roaring, it turned into smoke again and fell into the slot on the left side of the dual drive. The drive also pushed open to both sides. Then, a wisp of blue light flashed in the smoke. The smoke solidified and transformed into a mechanical dinosaur head above the left slot, resting on the right slot. The Tactical Horn, resembling a rhinoceros horn, also emerged.

At the same time, a surge of cold air condensed into ice in the right slot. Then, the dinosaur's lower jaw popped out of the machine and pieced together a complete skull. In that instant, the dinosaur's sharp blade shattered the frost, revealing the ice 'Fang' that shimmered with a ghostly blue light. The sound effect of 'Fang·Fang' immediately echoed between heaven and earth.

As the Dual Drivers activated, a white, frigid wave instantly engulfed Genji's figure. Pale blue ice crystals froze him inside, but dense cracks immediately appeared and burst open in the blink of an eye. Amidst a sky full of star-like ice crystals, the Kamen Rider's figure came into view—a form never before seen before.

The horns of 'W' are still there, but now they look more like the horns of a dragon. There are three scales that extend backward and rise in layers in the middle of the horns, all the way to the white tassels at the back of the head. There are also sharp decorations below the compound eyes, as if wearing a ball mask.

The knight's shoulder armor has also changed, with one short and one long barb resembling fangs on the inner and outer sides, and symmetrically facing hooks. The reinforced skin on his arms now features forearm armor connected to the wrist guards, somewhat resembling restraints.

While retaining the 'W' pattern on the breastplate, an additional false collar was added to enhance the texture of the armor. At the same time, a trench coat-like fabric protection extended from below the breastplate, with the color gradually changing from white to black from top to bottom, like an ink painting. It was then tied at the waist and then left loose, allowing the hem to sway in the wind at knee height. On the inner edge of the hem, there were three symmetrical, small, and menacing 'F' marks printed vertically at equal intervals.

At the same time, the Kamen Rider's entire body is adorned with a touch of dark blue, which softens the ferocious and brutal aura and adds a touch of solemnity. However, at first glance, he still looks like a grim reaper from the coldest hell.

"spread....."

Yuanxiang, sensing the power of the new form, flicked his hand, pointed at the dinosaur avatar, and whispered:

"Let us recount your sins."

"I don't have that kind of thing!"

The dinosaur, in its transformed form, swung its giant hand, raised its massive axe, and roared as it charged towards Yuanxiang:

"You, on the other hand, should take a good look at the sins of your rebellion against me!"

'boom!'

Almost immediately, the dinosaur incarnation appeared in front of Gengo and slammed down the giant axe, instantly unleashing a frigid storm. Anhk hurriedly used his power to protect Hino Eiji and the others behind him, thus preventing them from being frozen in ice.

After the icy fog dissipated, they saw Gengo catch the falling axe blade with only his left hand. No matter how hard the dinosaur avatar exerted its strength, Kamen Rider 'Fang Fang' remained motionless. Then, Gengo's left hand trembled slightly, and thick fog surged out. An energy phantom resembling a dinosaur skull appeared on his arm. With his movement, he fiercely clenched his teeth, and the giant axe blade shattered instantly, turning into tiny, crystal-clear ice crystals that fell to the ground. A pale, cold fog also spread outwards along the gap. The dinosaur avatar repeatedly exerted its power, but could only break off the eroded parts on its own before regenerating new axe blades.

"This...this is impossible..."

The dinosaur avatar couldn't accept what was happening before him. He roared and gathered the power of the Core Medal into his giant axe, frantically hacking at Gensou:

"How could the power of just four Core Medals possibly be a match for me?!"

"idiot."

Gensou calmly threw punches left and right, the dragon head phantom shattering the giant axe piece by piece, even the last section of the axe handle was crushed into particles. Then he grabbed the dinosaur avatar's hand, threw the several-story-high giant over his shoulder, smashing it into the ground and creating a terrifying trench. Then, he flicked his horn as 'TacticalHorn' three times in succession, triggering "Fang! Maximum Drive!" A thick white mist instantly enveloped Gensou, solidifying into a giant dinosaur phantom that leaped high into the air and then fell towards the dinosaur avatar.

During this process, the phantom began to mist, its outline fading away. From the open dinosaur's jaws, the Kamen Rider kicked out, followed closely by the mist, like a falling meteor, unstoppable!

"RiderKick!"

'Taku!'

The earth-shattering impact reverberated throughout the entire space, causing a surge of cold air to erupt from the ravine like a tsunami. But just as Anhk gritted his teeth, preparing to withstand the onslaught, the 'tsunami' seemed to be drawn back into the ravine by some force, triggering...

"Wow!!!"

Just as Shotaro and the others were shocked by this power, a sudden, shrill scream caught their attention. On the site of the old research institute, Professor Kannagi's figure appeared out of thin air, fell to the ground, and coughed up blood. He looked in horror at the ditch and saw the pale figure gradually emerge from it. The remaining six dinosaur-themed Core Medals were tossed high into the air by Kamen Rider as he walked, and the 'Fang' on his belt turned into white smoke and flew up, swallowing the Core Medals. Then, a crisp cracking sound reached everyone's ears.

Then, 'Fang' transformed into a dinosaur model, landed on Gensou's shoulder, stretched its neck as if burping, and faint traces of the purple glow belonging to the Core Medal could still be seen in its stark white body.

"He is you, and you are him..."

Genji, whose transformation had ended because of 'Fang's' departure, swayed slightly as he walked, speaking in a flat, monotone voice:

"Come on, let that dinosaur turn into a zombie and show me what it's like."

"Don't come any closer! Don't come near me!!!"

Professor Kannagi screamed, grabbing pieces of debris from the research lab and throwing them towards Genji. He scrambled backward on all fours, his powers gone the instant the 'Fang Fang' destroyed him. Even with the Core Medal still intact, the power of his Dinosaur form had vanished. He couldn't comprehend what had happened. Why had his meticulously planned and perfect scheme, along with his contingency plans, failed because of this mysterious Kamen Rider? He clearly... he clearly... wasn't in the 'future' he had envisioned!

"Who exactly are you? And what is that dinosaur prop?!"

"Me? I'm just a detective from Fuuto who happened to be passing by. As for 'Fang'..."

Yuanxiang raised his hand and patted his child's head, saying in an icy tone:

"He's an amazing partner of mine, so you better remember that!"

"Roar!"

As Gengo finished speaking, 'Fang' roared, bared its sharp teeth, and lunged at Professor Kannagi, intending to end his life. But at that moment, Professor Kannagi suddenly pressed a switch with his right hand behind his back, and the power of the universe was once again drawn down. Although it was very weak, it blocked 'Fang's' attack. Taking advantage of this opening, he casually swiped the switch to open a spatial rift and took out a ritual sword engraved with patterns. Haruto Soma immediately recognized that the patterns represented some kind of mysterious magic circle.

"Kamen Rider, this isn't over yet! Not over!"

The panic faded from Professor Kannagi's face, as if his earlier terror was all an act, but Genji still saw the despair deep in his eyes and realized that this would be the enemy's last counterattack.

"Fang!"

Gengo called out his comrades' names, and thick white smoke enveloped his body. Kamen Rider 'Fang Fang' reappeared. As Gengo transformed, the magical patterns on the sacrificial sword transferred to Professor Kannagi. Then, his body was covered in cracks and exploded.

This scene was familiar to Haruto Soma; it was the despairing state of the 'Gate,' the vision from which a new Phantom would emerge from its inner world. Haruto hurriedly tried to warn Gengo, but before he could speak, everyone saw Gengo, who had just been enveloped in white smoke, be engulfed by a pillar of fire that rose from the ground. And above the pillar of fire, a memory was flashing—

It was a 'Memory', the 'Memory' that the pterosaur monster had been holding all this time. Under everyone's watchful eyes, the memory was destroyed in the flames, but the data within it was clearly transferred into the strange flames.

At the same time, the power of the universe was drawn in again, intertwining with the flames. Then, a giant burning with flames, with a form similar to Kamen Rider 1, emerged from the pillar of fire. The powerful force even caused the entire base space to become unstable.

"Kamen Rider... Heh heh heh... Now I'm a Kamen Rider too!"

The fire giant examined its own body and chuckled in a deep, thunderous voice. Although it had lost the aid of the Core Medal and its current form was not what it was originally planned, this avatar, forged by combining Professor Kannagi's Despair Magic, cosmic energy, and the Gaia Memory, was already close to perfection. Professor Kannagi himself had not expected that this desperate struggle would actually give him a glimmer of hope for a comeback.

"Shoutaro!"

At this moment, Philip suddenly called out to his partner. The half-baked tough guy also realized that with the destruction of the 'Memory', he had regained his transformation ability. Without hesitation, he transformed into Kamen Rider W's 'Cyclone Joker Xtreme' form and used Prism Aegis to scan the enemy's situation. Then, they discovered that the previous pterosaur monsters had been acting under the concept of 'Kamen Rider', using the power of that memory to collect the memory data of past Kamen Riders.

Now, Professor Kannagi has merged with the 'painful' memories experienced by Kamen Rider in the data, becoming the current Kamen Rider Core!

233 Cores

"You all should die!"

A thunderous roar echoed in everyone's ears. The fire giant-like Kamen Rider Core unleashed a terrifying wave of fire, attacking Shotaro and the others. However, the fire energy he had used to seal Gensou was frozen by the cold air. The roaring dragon head phantom spiraled up along the frozen fire pillar and opened its mouth to bite Kamen Rider Core, but was immediately vaporized by the high temperature of the enemy. Only then did everyone truly realize the scorching heat of Kamen Rider Core.

"Fang!"

At that moment, Genji, clad in frost, rushed in front of Kamen Rider Core. His clenched left fist was shrouded in terrifying destructive power as he slashed at the enemy's neck. The fire giant's eyes lit up, and scorching rays shot out, also aiming for Genji's vitals. As the boy defended with a hand chop, a terrifying energy shockwave erupted in the air. Wave after wave of shockwaves caused the entire base space to tremble violently, causing countless cracks to appear out of thin air, as if the place would collapse and crumble at any moment.

but.....

"Why isn't this part broken yet?"

Yuto Sakurai muttered unconsciously. As the owner of the Time Train, he was quite experienced in the field of 'time and space', so the scene in front of him caught his attention. But at this moment, the battle in the sky had ended. Genji was pushed to the ground by the impact, and steam was rising from his white armor. He had clearly suffered a blow.

Kamen Rider Core was in an even more wretched state, with a gruesome wound running from his left shoulder to his right abdomen, almost cleaving his body in two. The cut surface of the wound was also filled with a chilling, spreading destruction, making it look like a fatal injury.

However, although Kamen Rider Core did groan in pain, the flames on his body began to intensify in the next second, and his wounds were healed as a result.

Where does he get so much energy?

Seeing this, Gengo couldn't help but mutter to himself. He knew very well the power of 'Fang Fang'. Although its main form was ice, its essence was the purest form of 'destruction'. Even if he used 'Joker', he would have to expend a great deal of energy to counteract it. The fact that Kamen Rider Core reacted so casually made Gengo realize that something was wrong.

After all, he had been fighting with Professor Kannagi from the very beginning. Even though this form was formed by the convergence of multiple forces, the most enormous cosmic power among them had not been completely drawn in or mastered. Such energy reserves were simply too exaggerated. It must be that there was some unknown backup plan.

"It's my turn, Taku!"

Just as Gengo was searching for an opening in Kamen Rider Core, the giant in the sky spread his limbs, and the flames on his body suddenly surged. In an instant, 'X'-shaped fire attacks rained down like a storm. Haruto Soma, who had already transformed, subconsciously tried to use magic to block it, but after he activated the power of the magician's ring, he was shocked to find that his defense was as fragile as paper in the face of this fire rain. In the end, Gengo shouted and unleashed his own power. The phantom of a dinosaur stood behind him and shot out countless fang-like blades of energy, wiping away the falling 'X' flames one by one.

"Senior, I'll hold the line from the front; I'll leave the rest to you."

After uttering those words, Gengo stomped his foot, and an ice tower rose from the ground. Although it was immediately destroyed by Kamen Rider Core, Gengo was able to leap high into the air while Core was distracted, just like when he sent Seele out of the Sea of ​​Quanta, attempting to engage Kamen Rider Core in mid-air.

However, Kamen Rider Core chose to avoid their attack, transforming into a final wave of fire rain that crashed down on Shotaro and the others. He then reassembled his body on the ground, and during this reassembly, his lower body transformed into the shape of a motorcycle. With its fiery tires spinning, the giant figure began to move like lightning.

In the blink of an eye, Kamen Rider W, Kamen Rider OOO, Kamen Rider Wizard, and Kamen Rider Fourze all screamed and flew backward. As they deactivated their transformations, they also spat out mouthfuls of blood, which evaporated into mist and disappeared as soon as it left their mouths. Each of them had an abnormal flush on their face, and the high temperature emanating from their skin was alarming.

"Go away!"

Kamen Rider Core wanted to press his advantage and kill the half-crippled Kamen Riders, but Gengo had already returned in mid-air, caught his rolling wheels with both hands, roared, and sent him flying, taking the opportunity to add a fang slash.

However, Kamen Rider Core responded quite flexibly. As the slash came flying, he split into zero, becoming fire snakes to dodge in all directions. At the same time, he attacked Gengo and the Kamen Riders behind him from all sides. The angles were so tricky that people couldn't help but marvel, just to force Gengo to not focus on one thing.

Gengo could easily see through the enemy's intentions. He inserted 'Cyclone' into his waist's special attack slot, activating 'Fang Fang's' special attack simultaneously. In an instant, a blue blizzard enveloped Gengo and his companions. However, Kamen Rider Core managed to stop it in time. All the fire snakes instantly gathered together, transforming into a drill, and launched an attack on a single point in the blizzard, attempting to break through the blizzard and kill the Kamen Riders outside of Gengo.

But just as Kamen Rider Core emerged, a pale figure burst forth from the snowstorm, directly confronting the oncoming Kamen Rider Core. At the same time, the power of the howling blizzard condensed on Gengo, and was then unleashed upon the enemy.

"Goo-wah~~!!"

Kamen Rider Core screamed and fell to the ground, his fiery body instantly turning into a sea of ​​fire, with frost still destroying it. But just like before, a mysterious energy source allowed him to recover from his injuries in the blink of an eye, rendering Gengo's previous efforts futile. Gengo couldn't help but groan, as the ultimate energy impact of 'Fang Fang' and 'Cyclone' had backfired on his body. At this moment, his internal organs were being tormented by both ice and fire.

But this price is perfectly acceptable! At the very least, it doesn't rely on 'blankness' to achieve its power, so no matter how much it struggles, it won't lose its memory.

"Hmph, it doesn't hurt or itch at all!"

Kamen Rider Core stood up with a shout, only to find that Shotaro and the others, whom he had severely injured, had stood up steadily. Unknown golden lightning was still dancing on their bodies, indicating that Kamen Rider Fang had performed some kind of healing on them during the blizzard.

"Zero-train!"

After the blizzard completely subsided, Yuto Sakurai did not hesitate to call upon his Time Train. As agreed beforehand, Tensei, while stabilizing the Paradox System on the train, also drove the train to break through the spacetime barrier and take everyone away from Gengo. Kamen Rider Core tried to stop him, but the white-clad rider intercepted him. Star-like frost floated around him, and the fangs and blades that gleamed with cold light reflected the fiercely burning figure of the giant.

"Your opponent is here, so don't be distracted."

"....court death!"

Kamen Rider Core noticed the look in Philip's eyes as he left. The way they looked at him, as if they wanted to dig out all his secrets, made him panic. He became even more eager to defeat Gengo and then hunt down those who left.

However, if Kamen Rider Core were to rely on his inexhaustible energy to wear down his opponent, Gengo would have to admit that it was feasible. But if he wanted to defeat Gengo head-on, he would have to ask 'Fang's' fangs for permission first.

The battle was about to break out, and the situation instantly shifted. Genji's methods were extremely cruel. In the battle where the memories were no longer burned, he showed off his skills without any concern, just like when he fought the 'museum' alone. With the help of 'Fang Fang' and other memories, he used the 'Inch Punch: Heaven Opening' move countless times on Kamen Rider Core.

Although Kamen Rider Core, who possesses seemingly inexhaustible energy, tried his best to fight back, it was still too difficult to break through and injure Genji's main body in the face of the power generated by 'destruction' and 'nothingness'. What made Kamen Rider Core secretly complain was that this person would switch to 'Joker' form from time to time and deliver a fierce blow to him in a dark gold form. The heavy punch combined with the explosive burst of short-range force made Kamen Rider Core feel like he might not be able to be saved several times. He was just barely holding on by relying on his backup plan.

However, I wasn't just taking a beating!

Kamen Rider Core roared, his body suddenly began to shrink rapidly, and at the same time, a defensive shield was erected. He used endless energy to forcefully hold off Genji, and then turned into an extremely dazzling point of light. Then, like a super planetary explosion, he continuously spread outward with an impact that was enough to burn the earth. Moreover, this wave was continuous, each wave stronger than the last, and he would not stop until he burned Genji to death.

Kamen Rider Core gritted his teeth, desperately squeezing out energy, wanting to end the battle as soon as possible. However, Genji's tenacity exceeded his expectations. While defending, Genji even tried to launch a counter-charge, which made Kamen Rider Core very anxious. In the current situation, this move was too risky. If someone found a weakness, he would have no chance of turning the tide.

"I found it."

Ok?

Unexpectedly, the very situation that Kamen Rider Core feared came out of Gengo's mouth. He stared in astonishment at his opponent, whose pale fingertips were wreathed in emerald green wind. Following the wind's guidance, the boy pointed to the ground and said in a deep voice:

"Here it is, your backup plan is hidden here, isn't it!"

"Damn it!!"
