Summon the Villain: Marvel.

In the warehouse district at night, the battle between Kamen Rider Na-Go and Kamen Rider Killer is still going on fiercely. The hatred and opposition between the two permeates the air, and the climax of the battle is about to come.

Kamen Rider Na-Go held the Beat Axe tightly, and she decided to release her ultimate move to end the battle.

Kamen Rider Na-Go (Kurama Neon) was extremely excited at this moment. She stood in the silent warehouse, raised the "Beat Axe" equipped with ice elements - her weapon, and prepared to release her first nirvana: "Tactical Blizzard".

In her equipment, there is a special tuning device called "ElementaDrum", which allows her to select music of different elements and incorporate it into the attack of the battle axe. To fight Kamen Rider Killer, she chose the ice element, which was her strategy in this battle.

Her fingers touched the button of "ElementaDrum" and selected the appropriate music. A breeze blew, and the temperature in the warehouse began to drop sharply. The chill condensed in the air, and her breath turned into white mist in the cold.

"Funk Blizzard!" A sound effect sounded, and a cold air current echoed in the warehouse. Cold air began to flow around Kurama Neon, and the blade on the battle axe began to emit a faint blue light.

She swung the battle axe without hesitation, slashing at Kamen Rider Killer. A biting cold wind burst out from the axe blade, cutting through the air and flying towards Killer. At that moment, time seemed to freeze, and everything seemed so slow.

But Kamen Rider Killer was not intimidated, his armor began to flicker, as if to resist the cold air. He stood there, revealing a mocking smile under his red eye mask.

"Tactical Blizzard!" Kurama Neon's voice was full of determination. She believed that her special move could defeat Kamen Rider Killer.

However, at that moment, Killer unleashed his killing power. A dark energy burst out from his body and collided with Na-Go's "Tactical Blizzard".

The two forces collided, and the air was filled with an atmosphere of extreme cold and darkness. Na-Go's icy airflow competed with Killer's dark power, and the intensity of the battle reached its peak.

However, gradually, Killer's dark power began to gain the upper hand. The cold air began to weaken, and the dark energy continued to erode it. Kamen Rider Killer showed a triumphant smile at the corner of his mouth, and his power became stronger and stronger.

Kurama Neon felt that the previous special move had failed to work, and she had no time to hesitate. She quickly switched the tuning device of the "ElementaDrum", this time choosing the music of the element of fire, and prepared to release the second special move: "Tactical Fire".

As the cold air had just dissipated, Kamen Rider Na-Go's axe gathered energy again. This time, Kurama Neon's expression was more determined, and he was determined to defeat Killer.

"Rock Fire!" sounded, accompanied by a blazing flame. Kurama Neon instantly swung her battle axe, releasing a wide range of flaming slashes. The flames burned like a flaming dragon, igniting the entire warehouse area in an instant.

The power of the flames was amazing, the flames devoured everything, the light was blinding. Kamen Rider Killer was trapped in the raging sea of ​​fire, his body was quickly surrounded by flames, and he could no longer escape.

Kurama Neon looked excited, she thought she could definitely defeat Killer this time. However, just as she was basking in the aura of victory, Killer's body began to change.

Killer's armor began to turn black, and although the flames burned vigorously, they seemed unable to really hurt him. His red eye mask revealed a cold smile.

"Tactical Fire!" Kurama Neon shouted again, trying to release another fire attack, but this time she felt that her power seemed to be offset by some force. The flames surrounded Killer but failed to cause any substantial damage to him.

Killer's dark power took over again, and his body began to gradually free itself from the flames. His armor became even harder, as if it could withstand any attack.

Kurama Neon's heart gradually became heavy. She knew that Killer was not an opponent that could be easily defeated. This battle was much more difficult than she had imagined.

Kurama Neon (Kamen Rider Na-Go) felt the urgency of time, and she knew she had to find an effective way to defeat Killer as soon as possible. She quickly switched the tuning device of "ElementaDrum", this time choosing a thunder and lightning elemental music, preparing to release the third nirvana: "Tactical Thunder".

The sound effect "Metal Thunder" sounded, accompanied by a strong breath of thunder and lightning. Kurama Neon swung the battle axe, releasing the power of thunder and lightning. At the same time, the electrical equipment in the warehouse was also activated and transformed into thunder and lightning attacks. The lightning was dazzling, and the arc burst in the air, forming a spectacular scene, and it was launched violently towards Killer.

The lightning attack was as easy as a finger, lighting up the entire warehouse space, as if it were a storm of lightning and thunder. Killer was surrounded by lightning, the current entangled his armor, and electric sparks exploded around his body.

Kurama Neon hoped that this time it would be successful. She knew that the lightning attack was powerful enough to defeat Killer. Unfortunately, just when she was looking forward to it, Killer's body changed again.

Killer's armor gradually absorbed the surrounding lightning energy, and his body began to emit a faint electric light. A cold light flashed under his red eye mask, as if mocking Kurama Neon's powerlessness.

"Tactical Thunder!" Kurama Neon kept shouting, trying to increase the power of the lightning attack, but she gradually felt her strength running out. The lightning attack seemed unable to really hurt Killer, and his armor became more and more indestructible.

Killer's dark power once again took over, and his armor even began to emit black electric light. Kurama Neon's expression became frustrated, and she felt that she could not defeat this indestructible enemy no matter what.

"Why!"

"Why!"

"Why!"

Kurama Neon couldn't understand why this happened, and used three special moves in a row.

"Hehehe, Little Apple, fall into my fear. Your fear will be converted into my strength." The killer felt the negative energy emanating from Kurama Neion.

"Power, power, I desire power." Kamen Rider Na-Go's eye mask turned deep red.

"Then I will lend you my power. Hurry up, hurry up, and give me the fear you carry." The killer said happily.

The final blow. Kamen Rider Na-Go quickly switched the tuning device of "ElementaDrum", this time choosing the music element, and prepared to release the last ultimate move: "Beat Strike".

The sound effect "Beat Strike" sounded, accompanied by a strong rhythm of music. Na-Go gathered the energy of the music in her feet, and her body was ready to go. She knew that this move was her last hope, and she had to be strong enough to defeat Killer.

"strength!"

Na-Go rushed towards Killer quickly, kicking with both legs continuously, each kick accompanied by the rhythm of the music, generating a powerful impact. Her feet quickly cut through the air, each strike accurately aiming at Killer's weak spot.

Killer was overwhelmed by the continuous kicks, and cracks began to appear in his armor, and the dark energy fluctuations became unstable. Kurama Neon continued to release the power of music, forcing Killer into a desperate situation.

"Come on, come on, come on."

"Hahahahaha."

Killer did not give up easily. A determined light flashed under his red eye mask, and his body began to emit dark waves. He resisted Kurama Neon's attack and persisted with gritted teeth.

The climax of this decisive battle finally arrived. The battle between Kurama Neon and Killer became more and more intense, with each kick accompanied by the energy of music, and each resistance accompanied by the power of darkness.

In a showdown between the top powers, the winner will inevitably emerge. Kurama Neon's tenacity and determination, as well as the power of her music, ultimately overwhelmed Killer. His armor collapsed, and the dark energy was defeated.

"Beat Strike!" Kurama Neon's voice was filled with triumph, and she kicked with her feet one last time, knocking Killer to the ground. The dark energy dissipated, and his armor became fragile and could no longer resist.

At the climax of the battle in the warehouse district, Kamen Rider Na-Go finally defeated Kamen Rider Killer. Killer's armor collapsed, the dark energy was defeated, and he was knocked to the ground and fell into a brief coma.

However, just as Kurama Neon breathed a sigh of relief and prepared to end the battle, a powerful dark energy began to gather in Killer's body. The atmosphere in the warehouse became more and more weird, filled with a dark atmosphere.

A hint of vigilance flashed in Kurama Neon's eyes, and she immediately realized that things were not over, but had entered a more dangerous stage.

Suddenly, Killer's body began to change dramatically. His armor cracked, and a dark smoke rose from it, forming a thick black cloud. Kurama Neon felt more nervous than ever before.

The black cloud gradually dispersed, revealing a new form, the second form of Killer.

Killer's body became larger, his muscles bulged, and his armor became stronger. His appearance became more terrifying, and his eyes under the red eye mask became colder. His power was several times stronger than before, and dark energy surrounded him, forming a powerful atmosphere.

"Hahaha, Little Apple, do you think you can defeat me easily?" Kamen Rider Killer in the second form laughed mockingly, his voice full of evil.

Kurama Neon felt her heart sink. She knew that Kamen Rider Killer was now more powerful than before and was an extremely formidable opponent. But she did not back down. She held the Beat Axe tightly, ready to continue fighting.

but.

Just as Kurama Neon was about to take action, she suddenly felt a black screen in front of her eyes and a feeling of dizziness came over her.

"support......"

"I can't go down..."
