'BOOOOM' A tremendous explosion erupts in cyber-punk like city, two girls were fighting a powerful enemy from another world. The girl, who had long white hair, was seen donning a mech battle suit and holding a longsword in her hand while gazing up at the enemy with her blue and orange eyes. Meanwhile, her companion, a girl with long pink hair, was dressed in a white and pink magical girl outfit, helped the blue-haired girl up and looked at the enemy with her blue eyes.

The man's black hair and red robe stood out as he held a cube in his hand and looked down at the two girls. He couldn't stop laughing, and his "HAHAHAHAHAHAHAHAHAHAHAH" echoed through the room. "So, this is the Star Cube, right?"

"I couldn't have imagined it," said the brown-haired man in a pirate costume with a trumpet in his hand. "Those two are in possession of the other Star Cube."

"Yes," replied the young girl, who wore cyberpunk clothing and had short brown hair. She glanced down at the two girls with her striking green eyes. "What a surprise it was to see both of you, Maya and Juri!"

"Aiko!" Juri shouted with anger in her voice. "There was no mistaking that it was you, I knew it without a doubt."

Maya posed the question, "Who are they?'"

With a laugh, Aiko gestured towards the two men. "On the right is Basco ta Jolokia, and on the left is Isaac. Using the Star Cube, I summoned them from another world to take the other Star Cube from you and kill you, heroes."

Juri's accusation cut through the tense atmosphere like a dagger. Her eyes blazed with fury as she confronted the person before her, a former ally turned enemy. The weight of betrayal hung heavy in her voice, laced with a deep sense of hurt. "You are a traitor," Juri accused, her voice trembling with a mix of anger and betrayal. "You not only murdered our master, the one who taught us everything we know, but you also dared to utilize the dark Star Cube." Her words hung in the air, the gravity of the situation sinking in. The dark Star Cube, a forbidden artifact of immense power, was believed to be nothing more than a myth. Yet here it was, in the hands of the one she once trusted. The sense of betrayal cut deep, leaving Juri grappling with a mixture of emotions - anger, sadness, and a burning desire for justice.

Aiko wore a smirk on her face while laughing maniacally, exclaiming, "HAHAHAHAHAHAHAHAHA! Tremble in fear, you worthless scum!"

"Juri, what do you think we should do now?" questioned Maya.

"There's just one way to do it, Maya" Juri said, pulling out the Star Cube and harnessing its power. "Calling upon the heroes from different dimensions, we humbly request your presence and aid in our time of need." The Star Cube emits a bright and radiant shine.

(? World)

As a portal suddenly materialized in the sky, a male figure with medium long black hair and dressed in a pirate outfit turned his attention towards it, captivated by its presence. Simultaneously, he heard a voice calling out for help, compelling him to investigate further. "Hmm!?"

With a mischievous smile on his face, he remarked, "Well, isn't this quite a wild time, huh?" as the light from the portal illuminated the room.

(? World)

Suddenly, a mysterious portal materializes in the sky, capturing the attention of onlookers. Among them, a man with medium short black hair, donning a white shirt accompanied by a black vest, black pants, and a hat, gazes up towards the sky. In that moment, he hears a voice urgently calling out for help."Hmm!?"

"Is there someone in need of help?" he asked, his voice echoing in the room as the bright light from the portal flooded the space.

(Back to the cyberpunk world)

As Juri was reaching the point of exhaustion, Maya and Juri's intense battle showed no signs of ending, leading Juri to utter a frustrated curse, "Shit!"

In a state of worry, Maya raised her voice, calling out "JURI!"

"Ready to meet your end?" Aiko asks Juri, a mischievous smirk playing on her lips.

Despite Juri's belief that she was going to die, her fear was quickly replaced with astonishment as the portal unexpectedly opened, coinciding with the simultaneous attack of flames and bullets on both Basco and Isaac. Aiko's eyes widened in shock and she couldn't help but let out a growl, demanding, "What!?"

Two figures rushed to her rescue, making their way towards her. One of them spoke up, asking, "Are you okay?"

"Yes, I'm fine," Juri responded as she rose to her feet. "Who are you?"

"Kamen Rider Saber," Isaac growled with disdain. "Or should I say Touma Kamiyama?"

Basco expressed his pleasure at seeing Captain Marvelous once more by saying, "Nice to see you again, Captain Marvelous."

Akio's face contorted in anger as she fumed, her eyes scanning the room to find that many heroes from other worlds had arrived. In a low, menacing tone, Akio growled out the command to "Fall back."

Juri and Maya heaved a sigh of relief as all three of them vanished from the field, and then they shifted their gaze towards the two men who were detransforming. Juri flashed a gentle smile and gracefully bowed as she expressed her gratitude, saying, "Thank you ever so much for your assistance."

With a smile, Touma responded, "Don't worry, it's not a problem."

Marvelous let out a sigh and asked, "Can you please explain to us what is going on, what this is all about, and where exactly are we?"

"Once we get back to the base," Maya said, "we will clarify everything."

"So, what are we now?" Juri asked, her tone serious. "We are currently in Justice City, known as the city of heroes. My name is Juri, and I belong to the Justice Hero Unit."
