After watching the previous video about the different world Y/n and the trouble he had with the world police. The Author decided to show them one of the worlds that he enjoyed quite so much.  As he is readying himself to show them the next world, he can't help but hear them talking about the previous world.

"Man, a world where Y/n is as awesome at biking as me! Now that's awesome!"Rainbow Dash said out loud toward Lynn Loud. Both of the two girls seemed to enjoy each other company as they talked a lot about sports.

"If Dabi did anything bad toward that idiot brother of mine...I'll kill him, "Bakugo said under his breath both worried and anger.

The Author looks at Anne and sees the girl seem to be gushing as she remembers the kiss that both alternates her and Y/n almost have.

"This next world is one of the places where I quite enjoyed. In this world, Y/n alongside Spike went on an adventure after stealing a valuable item from a museum.  The Author explained

"Spike is going to be in this world?"Twilight with a surprise. Some of her friends have the same surprised expression as her. "Yeah! A world where Y/n and I worked together!"Spike shouted out in joy. Spike and Y/n have a good relationship as the young boy sees Y/n as a great big brother.

"Well...yes...but I'm shocked that you guys didn't notice that the Author said that Y/n and Spike are trying to sell an item or something at the museum?"Pearl told the girl who went quiet when they heard this.

"Eh, won't be the first time breaking into someplace and stealing something," Spike told the gem lady. Pearl and some of the people in the room looked at the young boy in bewilderment.

"Y/n and Spike both must have a good reason on why they steal that stuff...I hope"Sam told them all as Mitsu and Momo looked at each other with a wide grin. Why? Cause they are going to see their big cousin as a robber.

Before they can ask The Author any more questions, he starts the trailer for the new world. "Oh, and by the way, this world may confuse all of you a bit, but there's a good explanation of what is happening."The Author added.

BEGIN...

The video started with Y/n voices that can be heard saying "Oh, this is it! This is it!". We can the Spike point of view as he looking at a guard who is having a problem with his flashlight while hiding behind a bush.

"Where is this?"Issei asked when he saw the building.

"That's a museum," Weiss replied, her tone laced with a touch of exasperation. "The Author mentioned it earlier. I thought you knew."

"Boring! There's nothing good there. Only old and boring stuff" Amethyst yawned.

"What? I love the museum! It's full of historical and interesting artifacts. There's so much to learn." Twilight said with a happy tone with her eyes lit up with enthusiasm. 

"I have to agree with the purple gem lady. It's boring. Plus...what are they even going to steal there?"Neptune shrugged, unimpressed.

"You do know that a lot of stuff in museums is priceless, right? Historical artifacts, rare items... they can be worth a fortune." Lisa chimed in, her tone was slightly incredulous.

"Be careful little dude!" Luna said in a worried tone, fearing that Spike would get caught.

"This is gonna change our lives forever."Y/n voice can be heard as Spike is readying himself to climb up the wall. We see Spike trying to hide from the guards who are Neptune and Sun. "They gotta be around here somewhere" Neptune's voice can be heard.

"Hey, Neptune! It's us!"Sun said with an excited tone when he saw him and his friend on screen.

The groups erupted in laughter and excitement at the sight of Neptune and Sun in their roles as museum guards. Sun's enthusiasm was contagious, but Neptune seemed less thrilled.

"We're guards?!" Neptune grumbled, his voice dripping with disbelief. "I'd rather be cops or even detectives. At least that would be more interesting."

"Sneaky time," Spike whispered with a grin, his eyes twinkling with determination. Fluttershy chuckled softly, her laughter a gentle counterpoint to the tension.

"Be careful, Spike," Fluttershy said, her voice a blend of concern and encouragement. "We don't want you to get caught."

"You're right. You know what, you're right. But what we need to split up...cover more ground."Sun suggested. Spike just watched the two having the conversation while still hiding. "That's a great idea! I love that idea!" Neptune said with full enthusiasm while poking Sun's chest with the gun he is holding.

Blake and Weiss, who had been watching, exchanged a knowing glance before speaking in unison. "Both of you are idiots," they said, their voices carrying a blend of exasperation and concern.

Neptune and Sun looked at each other with hurt and confused expressions. "What?!" they exclaimed in unison, their faces a mix of disbelief and discomfort.

Weiss was quick to elaborate, her tone sharp yet concerned. "Why would you poke yourself and each other with a gun? What if you accidentally shoot yourself?"

The boys exchanged sheepish glances, their previous enthusiasm giving way to a dawning realization of their mistake. Neptune and Sun didn't have a comeback, their faces flushing with embarrassment.

Blake sighed, her arms crossed. "Honestly, you two should be more careful. This is serious."

"Classic Neptune and Sun," Ruby said with a laugh. "Always managing to get themselves into trouble."

"Where is Y/n? We only heard him talk but we haven't seen him" Akko, who had been waiting patiently, chimed in with a hint of concern as she looked everywhere for her friend. 

"Now, stick to the plan and you'll be just fine," Y/n said as he looked at Spike. "But if you deviate from it for a single moment...I won't come back for you" Y/n said with full seriousness before saying "Okay? Good Luck!" with a cheerful tone before harpooning himself up.

"Thanks for the pep talk Y/n"Sasha sneer.

"Yeah...real good pep talk," Spike said, shivering at the thought of Y/n leaving him if there's a problem. But he knows that the Y/n in his world wouldn't do that, but what about Y/n in this world?

"So, your world's Y/n isn't one for pep talks either?" Steven, curious about the different versions of Y/n, turned to the blonde-haired girl and asked, 

 "I think all of our world's Y/n are pretty bad at pep talks. They tend to be more... awkward than inspiring." The girl, Sucy, shook her head with a knowing smile.

Everyone nodded in agreement, recalling their own experiences with Y/n's attempts at motivation. Each memory was met with a mix of amusement and embarrassment, highlighting the universal awkwardness of Y/n's pep talks.

Felicia, who had been quiet up until now, couldn't help but smile as she thought back to a particularly memorable moment. As Y/n's friend and secret crush, she remembered the time when Y/n had given her a pep talk before a public speaking event.

Felicia had been nervous, her hands shaking as she prepared for her speech. Y/n, eager to help, had tried to offer words of encouragement, but his efforts had come off as endearing yet cringe-worthy. He had fumbled over his words, mixing up his sentences and awkwardly patting her on the back. Despite the clumsy delivery, his genuine intention was clear, and it had made her blush, her nerves momentarily forgotten.

We see a brief glimpse of places and see Y/n doing flips and more places. We then see Spike and Y/n running from Sun and Neptune. Y/n walks upstairs before running alongside Spike in what seems to be a sewer.

"Wow! Y/n is pretty flexible!" King exclaimed, clearly impressed by the display of athleticism. His eyes were wide with admiration as he watched Y/n's aerial manoeuvres.

"Hmmm... very flexible... nya," Kuroka purred, her gaze lingering on the screen as she licked her lips. Her reaction was both appreciative and suggestive, showing a deeper interest in Y/n's flexibility.

Spinel, noting Kuroka's reaction, tried to remain composed. "Not as flexible as me, but it's enough to even make me impressed," she said, demonstrating her impressive flexibility by elongating and spinning her arm. Despite her effort to deflect attention, she couldn't ignore Kuroka's moan of approval.

Amanda, observing the various locations being shown, furrowed her brow in thought. "Hmm... there's a lot of places this trailer is showing. I wonder why?" Her curiosity was piqued as she considered the significance of the diverse settings.

"They are on the run!"Nora shouted so suddenly when Y/n and the Spike onscreen ran. Her sudden exclamation caught everyone's attention, adding to the intensity of the moment.

"The sewer? Yuck!/Yes!"Both Lana and Lola said. One is disgust and the other is joy.

Y/n driving a car with Spike behind him. The vast open sea. Y/n and Spike running again but is now outside of the museum. A guard Blair-Witch style with a sack covering him. Y/n and Spike running from zombies.

"A getaway car! Nice thinking."Issei said, clearly impressed by Y/n's quick thinking. The sight of the car was a moment of relief amid the chaos.

"Finally! They can escape the museum!"Eda said out loud, proud of her nephew.

 "Wait... the sea as well? I don't understand... Is Y/n and Spike running from the police around the world?" Ena, watching the unfolding events, turned to her sister Fumiko with a puzzled expression.

 "It seems like it. They did steal something, so that makes them fugitives. But the extent of their chase is a bit much." Fumiko, equally confused, shrugged.

"I mean...they did still steal something. That makes them a fugitive by the law" Juzo said to them.

"And they will be caught, "Endeavour said flatly to all of them.

The grim reality of the situation was not lost on the viewers. Kali, noticing the guard stumbling with the sack over his head, shivered slightly. "Oh... that's creepy," she said to her husband.

"Now there's zombies as well?! What is this world?!" Denki, overwhelmed by the escalating chaos, shouted in frustration.

"I can't believe they're dealing with zombies now," Luz added. "This is turning into a full-on action movie."

The absurdity of the situation was not lost on anyone. The combination of high-speed chases, zombies, and the looming threat of capture created a chaotic yet exhilarating viewing experience. The various elements—the getaway car, the sea, the stumbling guard, and the zombies—blended into a thrilling and unpredictable narrative.

Y/n and Spike avoiding bullets that are hitting a bunch of barrels. Hop Pop laughing evilly while looking at Spike behind a door.

"I know you both want to do the right thing and all that," Peridot commented to Neptune and Sun, her tone laced with exasperation. "But I think shooting a barrel full of explosives is not a good idea." Her remark highlighted the absurdity of the guards' actions, as Neptune and Sun were left with no choice but to hide, their earlier enthusiasm now replaced with a sheepish realization of their mistake.

"Whoa, there Hop Pop!" Sprig said, noticing the old frog's menacing demeanour. "Forget to take your medication or something?" His comment was laced with concern and a hint of humour, attempting to diffuse the tension with a playful jibe.

Hop Pop's glare was sharp and intense as he turned his attention to Sprig. "What do you say, boy?!" he demanded, his voice tinged with irritation.

"N-nothing," Sprig stammered, clearly intimidated by his grandfather's imposing presence. He shifted uncomfortably, avoiding eye contact and hoping to defuse the situation.

"You!" Ozpin pointed at Spike while some of the people in the cinema room were there. Y/n trying his best to save Spike who seems to be passed out.

Barbara Parker, who had been watching the unfolding drama with increasing concern, suddenly noticed something alarming. She glanced down at her counterpart's attire and saw that she, along with some of her friends, was dressed in prison clothes. Panic set in as she exclaimed, "Wait, are we in a prison? What did I do?!" Her confusion and anxiety were palpable, as the realization of their imprisonment sank in.

"I can't be in prison! What have you done to yourself another world me?!" Bobby Santiago yelled dramatically. His outburst was met with a mixture of sympathy and frustration from those around him. Ronnie Anne, rolling her eyes at her brother's exaggerated reaction, tried to remain calm in the face of the unfolding chaos.

"It seems that Spike is dying and Y/n doing his best to save him."Lisa pointed out.

The impact of the scene was especially intense for Twilight, who was visibly shaken. Her voice quivered with fear as she cried out, "Oh God! Spike! Please don't die!" Her emotions were raw, and tears threatened to spill as she watched Y/n's desperate attempts to revive Spike. "Please, Y/n, save him," she added, her words pleading and heartfelt. The weight of her concern was evident, and her emotional investment in Spike's fate was clear.

Despite the fear and panic, Spike, though conscious, was deeply unsettled by the sight of Y/n struggling to save his otherworld counterpart. He knew that he wasn't in immediate danger, but the distressing image of Y/n's frantic efforts was both alarming and sobering. The duality of seeing himself in peril while knowing it was an alternate version only heightened the emotional impact of the scene.

"You. Right in the eyes."Neptune said to Spike while pointing his gun at him. Y/n walks toward him slowly, using plants as a cover. Spike is running and we see a picture of Y/n on a large portrait.

"Is Y/n using a plant as cover to attack Neptune?" Yang asked, her voice filled with disbelief as she observed the scene. The strategic use of the plant, combined with the suspenseful music, made the moment feel both intense and oddly humorous.

"Y/n's using a plant as cover—really?" Steven said, trying to grasp the scene's blend of seriousness and absurdity. "This is like something out of a cartoon."

"That's so cartoony! Hahahahaha!" Amethyst laughed heartily, joined by the kids who found the scene's exaggerated nature amusing. The contrast between the serious situation and the cartoonish cover added a layer of surreal comedy.

"Who is Spike running from now?!" Rarity asked in confusion, her concern evident as she watched Spike's frantic escape from what appeared to be a lab. The sight of him darting away only intensified the mystery of the pursuit.

"Maybe from the cops or the zombies?" Ren suggested, trying to piece together the unfolding narrative. The blend of threats created an atmosphere of constant danger and uncertainty.

They soon noticed the large portrait of Y/n in the dark.

"That portrait of Y/n is seriously creepy," Amanda added, echoing the unease felt by many. "Why is it there? It's so out of place."

Hawks's question, voiced aloud, captured the collective sentiment. "...that's creepy... why is that thing there?" His reaction was shared by many viewers, who found the large portrait unsettling amidst the high-stakes action.

More Spike running. Spike is in the cell while yelled at by Michael Williams, who is a guard. "I hope you're happy!"

"For what? Getting caught? Of course not!" Spike retorted, his voice tinged with frustration. Despite his defiant tone, there was a palpable sense of defeat as he faced the guard. Michael's expression softened, a flicker of remorse crossing his face as he looked at the trapped boy.

"If Spike is caught... then Y/n as well," Oscar said, his tone heavy with concern. The implication that Y/n might also be in trouble added a layer of worry for those invested in their mission.

Setsuna, however, was less concerned. She shook her head, her confidence in Y/n's abilities evident. "I doubt it. Y/n is hard to capture. He has a lot of plans in his mind. He once told me he had a plan to stop all of us in Class 1-B and Class 1-A. So I doubt he would let himself get captured."

The students of Class 1-B, as well as Monoma, nodded in agreement. Monoma's acknowledgement was grudging but sincere. They had seen Y/n's tactical skills firsthand and knew that he was not easily outmanoeuvred. Class 1-A can't help but be scared about this very facts.

We see Issei walking toward the viewer saying partner before his face changes. "Watch your head, "Jaune who looked like he hadn't shaved for a long time said to Spike.

"Woah... did my face just change?" Issei asked, his eyes wide with confusion as he looked at himself on the screen. His friends around him were equally perplexed by the sudden shift.

"Yeah... what was that all about?" Kiba chimed in, mirroring Issei's bewilderment. The unexpected alteration of Issei's face left everyone feeling a bit unsettled.

"Jaune... you look horrible," Nora shouted, her voice filled with a mix of concern and teasing. "Like the time you didn't finish an assignment that Miss Glynda gave and had to stay up all night to finish it!" Her comment was a playful jab at Jaune's past struggles, drawing laughs from some of the viewers.

Jaune, clearly annoyed, shot Nora an exasperated look. "You had to make me remember that, don't you?" he said, his tone a blend of frustration and resignation.

Nora simply smiled innocently, enjoying the opportunity to tease Jaune. "Just bringing up old memories," she said with a shrug.

"Best friend, "Kirishima said while pointing a gun at Spike. Y/n is behind him. Readying himself to knock him down. Spike dives into the ocean before we see him at a lab with Marcy aiming a futuristic weapon at Spike while yelling "Traitor!"

"Sorry about that, Spike," Kirishima's voice cut through the confusion, offering an apology from a distance. His remorseful tone contrasted sharply with the earlier tension, adding a layer of complexity to his character.

"It's okay. It wasn't your fault," Spike replied, his voice calm despite the chaos. The understanding between him and Kirishima hinted at a deeper, perhaps unresolved conflict.

"Don't try to hit Kirishima, Y/n. It wouldn't end well for you," Coco warned, her tone matter-of-fact. The gravity of the situation was evident as she explained the implications.

"Why's that?" Ruby asked, her curiosity piqued. The tension in the scene was thick, and Ruby's question reflected the confusion of the audience.

"Because Kirishima has a gun...duh," Coco said as if the answer was self-evident. Her nonchalant demeanour contrasted sharply with the seriousness of the situation, adding a touch of dry humour to the scene.

"Everyone and everything wants to kill me," Spike lamented, his frustration evident. His words conveyed the overwhelming sense of danger and betrayal he felt as he navigated through these precarious situations.

"Both you and Y/n," Sunset said, her voice filled with sympathy. The duality of Spike and Y/n's predicaments highlighted the shared struggle they faced.

As Marcy watched the screen, she saw her image holding a weapon and aiming it at Spike. Her expression shifted to one of confusion and self-doubt. "Traitor?" she muttered to herself, grappling with the sight of her actions. The realization of her role in the unfolding drama added a layer of internal conflict to her character.

We then see a small wooden carved box. The thing that Y/n and Spike are trying their hands on.

"...that's it? That's the thing they are risking their lives to steal? A carved box with a blue gem on it?" Amanda grumbled, her frustration evident. The box's seemingly ordinary appearance was a far cry from the grandiosity she had anticipated, and she couldn't help but feel disappointed by the anticlimax.

Eda's eyes twitched as she took in the sight of the box. To her, it appeared to be a valuable but ultimately unimpressive artifact. "It may be priceless, but it doesn't seem worth all this trouble," she said, echoing Amanda's sentiment. Her scepticism about the box's significance was clear, and she was visibly unimpressed by the object's understated appearance.

Izuku, trying to offer a different perspective, spoke up in defence of the box's importance. "It must be more than meets the eye! Someone must have promised them a good price for it," he suggested. His attempt to rationalize the risk and effort involved highlighted his belief that there was more to the box than its outward simplicity.

A HEIST WITH Y/N

"So much trouble....all for something so small"A dark and sinister voice of Y/n can be heard.

"Was... that... Y/n?" Ochako asked, her voice trembling slightly. The fear in her tone was palpable, reflecting the unsettling effect of the sinister voice.

A few people in the room shivered as the darkness in Y/n's voice contrasted sharply with their usual perceptions of him. His voice, usually filled with warmth and confidence, was now laced with a menacing edge that sent goosebumps down their spines.

"Is Y/n... the bad guy... in this world?" Lincoln asked the Author, his voice tinged with anxiety. Erma and others around him looked equally shocked and confused, struggling to reconcile the image of Y/n they knew with this disturbing portrayal.

The Author, noticing the growing concern, spoke with a gravity that matched the situation. "Why do you think that? Is it because of the dark and sinister tone of voice? No... Y/n is not the bad guy, nor is Spike. That's not Y/n you're hearing, but something far worse."

The Author's serious tone and the implied threat of something "far worse" created an atmosphere of tense anticipation. The viewers looked at the Author, their eyes wide with fear and curiosity. The implications of these words were unsettling, suggesting a deeper and more sinister reality beyond the surface of the narrative.

END

As the trailer ended, the room was filled with a mix of reactions, reflecting the intense and complex emotions stirred by what they had just witnessed. The audience sat in stunned silence for a moment, processing the twists and revelations.

"Well, that was... intense," Ruby finally broke the silence, her voice reflecting a blend of awe and concern. "I didn't expect it to be so dark."

"Yeah," Steven agreed, still trying to wrap his head around the sinister twist involving Y/n. "That voice—something is going on that we haven't seen yet."

"Something far worse, apparently," Amethyst said, her usual playful demeanour subdued by the gravity of the trailer. "What does the Author mean by that?"

Ochako, still a bit shaken, added, "It's like Y/n is being used by something or someone else. It's so different from what we know of him."

Lincoln, who had been watching with a mix of worry and curiosity, nodded in agreement. "I hope there's a way to clear this up and find out what's going on."

"Yeah, the whole thing felt creepy," Emiko said, her voice reflecting the shock and confusion shared by many in the room.

The Author, sensing the unease, addressed the group with a reassuring tone. "I understand it's a lot to take in. The trailer is designed to mislead and create suspense. Y/n and Spike are not the villains, but rather pawns in a much larger, more complex conflict. As the story unfolds, you'll learn more about the true nature of the threat they're facing."

"Okay, but what exactly is that threat?" Amanda asked, her curiosity piqued despite the tension. "Can you give us any hints?"

The Author paused, considering how much to reveal. "The threat is deeply tied to the mysterious box and the forces manipulating events behind the scenes. The world they're in has layers of deception, and the true danger comes from an entity that seeks to exploit the chaos for its purposes. It's not just about the box—it's about the control and influence exerted by this entity."

The room buzzed with whispers and questions as everyone absorbed the Author's explanation. The promise of a deeper and more intricate plot beyond the trailer's initial impressions sparked both excitement and trepidation.

"Well, I guess we'll just have to wait and see how it all unfolds," Eda said, trying to bring some positivity to the group. "It sounds like there's a lot more to the story than we've seen."

"Yeah, definitely," Sunset agreed. "I'm looking forward to finding out what happens next."

As the conversation continued, the group's initial shock began to fade, replaced by a renewed sense of curiosity and anticipation. The trailer had set the stage for a complex and thrilling narrative, and everyone was eager to uncover the full extent of the story's mysteries.
