Hiro and Yui trudged through the dense forest, their clothes and hair damp from the humidity. Yui was feeling frustrated, and it showed in her tone as she voiced her concerns about finding their missing classmates. "This is such a pain. We're never going to find our classmates at this rate," she grumbled.

Hiro tried to remain optimistic, knowing that giving up was not an option. "Don't give up yet, Yui! We just have to keep searching and stay determined! We'll find them, I'm sure of it."

The forest was vast and seemingly endless. The canopy was thick with a tapestry of leaves that varied in shades of green, from the deepest emerald to the lightest mint. Shafts of sunlight filtered through the leaves, casting dappled patterns on the ground below. The trunks of the trees were massive, some so wide that it would take several people to encircle them with their arms. The bark was rough and deeply grooved, giving the impression of ancient, wise beings that had stood sentinel for centuries.

As Hiro and Yui made their way through the forest, they could hear the soft sounds of nature all around them. The gentle rustling of leaves as a slight breeze passed through, the chirping of birds as they flitted from tree to tree, and the occasional scurrying of small animals in the underbrush. The scent of the forest was fresh and invigorating, with the tang of pine needles mixing with the sweet fragrance of flowers.

But despite the beauty of their surroundings, Yui couldn't ignore the uneasy feeling that lingered in the pit of her stomach. "Hiro, I don't like this. It feels like we're being watched," she said, her voice low.

Hiro nodded in agreement, his eyes darting around in search of any signs of danger. "I feel it too. But we can't let that stop us. We have to keep moving forward."

As they continued their journey, they stumbled upon a clearing in the midst of the towering trees. In the center stood a tree so large it almost seemed to touch the sky. The pulsing green light that emanated from it was otherworldly, casting an eerie glow across the clearing. It was a sight to behold, and both Hiro and Yui couldn't help but feel drawn to it.

The forest seemed to have a life of its own, a living entity that pulsed with energy and mystery. As they journeyed deeper into the forest, Hiro and Yui began to feel a sense of awe and reverence for the natural world around them. It was a reminder that they were small beings in a vast and powerful universe, and that there were forces at play that were beyond their understanding.

Yui's eyes widened as she pointed to the tree. "What is that?! It's like nothing I've ever seen before!"

Hiro's curiosity was piqued. "This must be important! We have to investigate!"

As they approached the tree, the pulsing green light grew brighter and brighter, until it was almost blinding. And then, just as suddenly as it had appeared, it faded away.

Yui and Hiro continued their search for their classmates and stumbled upon a serene stream. "Hey, this water looks pure enough to drink," Hiro said as he knelt down to take a closer look.

Yui cautioned, "We should be careful. We don't know what kind of creatures could be living in there."

As they walked along the stream, they noticed the twisted and gnarled trees around them. Suddenly, they heard a rustling in the nearby bushes. "Be careful, Hiro. We don't know what's lurking out here."

To their surprise, a small creature with bright blue fur emerged from the bushes, harmless and adorable. "Aww, it's so cute! Maybe we can catch it and see if it's safe to eat," Hiro said with a grin.

Yui sighed. "Hiro, please focus on the task at hand. We're trying to find our classmates, not have a picnic."

After hours of searching, they returned to the circle of light. Yui shook her head in disappointment. "Well, that was a waste of time. We didn't find anything."

Hiro remained optimistic. "We may not have found anything yet, but we're getting closer. We just have to keep trying!"

Yui rolled her eyes. "Whatever you say, Hiro. Let's just go home and regroup."

As they turned to leave, they noticed something strange - the circle of light was gone. The tree that had emanated the pulsing green light was still there, but now it was just an ordinary tree.

Yui was alarmed, "Hiro, where did the circle of light go? And what happened to the tree?"

Hiro looked around, trying to make sense of the situation. "I'm not sure, Yui. Maybe it was just an illusion?"

But Yui knew better. "No, it was real. I felt it. There's something strange going on here."

They continued on their journey, but now they were even more on edge. As they walked, they noticed that the forest seemed to be closing in around them, the trees growing denser and the atmosphere growing darker.

Suddenly, they heard a voice calling out to them from the shadows. "Hey, you two! Over here!"

Yui and Hiro exchanged a wary glance, but cautiously made their way towards the source of the voice. As they drew closer, they saw a figure emerge from the darkness - it was one of their missing classmates!

Relieved, Yui rushed forward. "Oh thank goodness, we've been looking for you! Are you okay?"

The classmate nodded, but looked scared. "Yeah, but we have to get out of here. Something's not right."

As they made their way out of the forest, Jaune kept looking back, as if he was being followed. Yui and Hiro could see the fear in his eyes, and they knew that something was terribly wrong. They quickened their pace, but the thing behind them seemed to be gaining on them.

Yui grabbed Jaune's arm. "Come on, we have to hurry! We're almost there!"

But just as they were about to reach the circle of light, something grabbed Jaune from behind. He screamed and thrashed, but it was no use. The thing was dragging him away, its dark tendrils wrapping around him like a serpent.

Yui and Hiro tried to pull him back, but the thing was too strong. Jaune's screams echoed through the forest as he was dragged away from them, his body twisting and contorting as he was devoured by the darkness.

In that moment, Yui and Hiro knew that they had to make a choice - stay and try to save Jaune, or run for their lives. They knew what they had to do.

They turned and ran towards the circle of light, their hearts pounding with fear. They could feel the darkness closing in around them, its hungry tendrils reaching out to devour them.

But just as they were about to be overtaken, the circle of light appeared again, shining brightly and keeping the darkness at bay. Yui and Hiro rushed towards it, and the moment they stepped inside, they were transported back to their own world.

And as they stumbled out of the circle, gasping for breath. They were back in their school's homeroom, surrounded by the familiar walls and desks. They looked at each other in disbelief, still trying to process what they had just experienced.

Suddenly, Yui's phone rang. Her hand trembled as she held her phone to her ear. She struggled to form words, still reeling from the events in the forest. Hiro put a comforting hand on her shoulder as she answered the call.

The she spoke up, "Yes, officer. We were in the forest and we found one of our missing classmates, Jaune. But something attacked us and we had to flee. We were able to make it back to our school, but Jaune... he didn't make it. It was like something swallowed him whole."

And after she had explained the situation siren blare and as the department of investigation rush down to the exclusive Sakura high school, it seem like the world have stop as if a god have fail and the devil have the advantage the the external game of chess.

And when the police arrived, they listened to Yui and Hiro's story with a mix of disbelief and concern. One officer spoke up, "Kids, we appreciate your bravery in coming forward, but we can't stress enough the importance of not exploring unknown places without proper information or authorities present. Your friend might have been saved if you had contacted us first." Another voice cut in, "Excuse me, officers. I'm from the Department of Paranormal Investigations, and I'd like to speak with these two."

Hiro and Yui looked at each other in confusion as a man in a suit entered the room. He introduced himself as Agent Lee and began to ask them questions about what they had seen in the forest.

Yui and Hiro did their best to recount their experience, but the agent seemed skeptical. "A circle of light? Demonic entities? Are you sure you didn't just stumble upon a drug operation or a prank gone wrong?"

Yui felt her frustration mounting. "No, we're sure. It was real. We saw it with our own eyes."

Agent Lee nodded, but his expression was still doubtful. "Well, we'll investigate further. In the meantime, I suggest you two stay away from that forest. And if you ever come across anything like this again, please contact the authorities immediately."

Yui and Hiro nodded, still reeling from their traumatic experience. As they left the school with their parents, they couldn't help but feel a sense of loss. They were the only ones left in their year group, and now they had lost a friend.

Yui turned to Hiro and said, "I can't believe what we went through today. Do you think anyone will ever believe us?"

Hiro shook his head, "I don't know, Yui. But what I do know is that we have to stick together. We can't let this break us."

Yui nodded, "You're right. We'll get through this together."

And both of them promise that they will find the truth and get to the bottom of the story, they grow older, and as the day rolls by the ceremony progresses, the once celebratory atmosphere that seem to be in every graduation ceremony turn somber, as the once full grand hall of Sakura high remain empty as families grieve for they lost Hiro and Yui accept they diplomas with a heavy heart. And as the principal of Sakura high stands up to speak

As the principal of Sakura High stood up to speak, the families of Hiro and Yui remained standing, their hearts heavy with grief and unanswered questions. The once celebratory atmosphere of the graduation ceremony had turned somber, with the once-full grand hall now empty.

The principal's voice echoed throughout the silent room, "We gather here today to celebrate the achievements of our graduating students, but also to mourn the loss of graduation class 100 I offer my condolences to the families that haven’t found they child, children who have been with us for many year and that they will forever remain in our hearts and memories."

And as Hiro and Yui accepted their diplomas with a heavy heart, their eyes filled with determination to find the truth. As they walked off the stage, they knew that their mission had just begun. They couldn't let their classmates' disappearances go unanswered.

The sound of weeping parents and grieving friends echoed throughout the auditorium as they left. It was a painful reminder of the devastating loss that had occurred. But Hiro and Yui were determined to find the answers and bring closure to those left behind.

As they walked out of the grand hall, they knew that they would have to navigate through the complex and challenging path ahead of them. They were ready to face whatever came their way, and with each step they took, their determination grew stronger.

Together, they would uncover the truth and bring justice to their missing classmates.

10 Year later Hiro was an up-and-coming star in the scientific world, his research being the topic of discussion at numerous conferences and academic gatherings. He had always been passionate about discovering the mysteries of the universe and had spent countless hours in his lab, working tirelessly to uncover new insights into the workings of the cosmos.

Yui, on the other hand, had chosen a career in law enforcement. Her passion for justice and her strong sense of morality had led her to become a police detective. She had worked her way up the ranks and was now known as one of the most skilled detectives on the force.

Despite their different paths, Hiro and Yui had remained in touch over the years, meeting up occasionally to catch up on each other's lives. During one such meeting, they found themselves discussing a particularly interesting case that Yui was working on. It involved a group of criminals who were using advanced technology to commit their crimes.

Hiro's scientific mind was immediately intrigued, and he offered to help Yui in any way he could. Together, they began to investigate the case, with Hiro using his expertise in technology and Yui using her investigative skills to piece together the clues.

As they delved deeper into the case, Hiro and Yui discovered that the criminals were using a highly advanced and encrypted communication system to plan and execute their crimes. It was a system that even the most sophisticated law enforcement agencies in the world had been unable to crack.

But with Hiro's scientific knowledge and Yui's determination, they were able to make progress. Hiro spent long hours in his lab, analyzing the encrypted messages and searching for patterns. Yui, meanwhile, interviewed witnesses, tracked down leads, and followed her instincts to uncover more clues.

Their efforts paid off, and they were finally able to piece together the entire criminal operation. It turned out that the criminals were using stolen technology from a top-secret government program, which Hiro was able to trace back to a rogue government agency.

Together, Hiro and Yui worked tirelessly to bring the criminals to justice, and their success was widely celebrated in the media. But for Hiro and Yui, it was just another day in their pursuit of truth and justice.

As they sat together, exhausted but elated, Yui turned to Hiro and said, "We make a great team, don't we?"

Hiro smiled and replied, "We always have, and we always will."

Yui nodded in agreement, and then leaned back in her chair. "You know, Hiro, I still can't believe that we're here, working together like this."

Hiro looked at her quizzically. "What do you mean?"

"I mean, think about it. We were just a couple of kids, exploring the woods and stumbling upon a magical tree. And now, here we are, all grown up and solving crimes together."

Hiro chuckled. "Yeah, I guess it is pretty surreal when you think about it. But you know what they say, truth is stranger than fiction."

Yui smiled. "I guess you're right. And speaking of fiction, have you been keeping up with any of the latest sci-fi books?"

Hiro's face lit up. "Of course! I just finished reading the latest one by Isaac Asimov. Have you read it yet?"

Yui shook her head. "Not yet, but I've heard great things about it. I've been meaning to pick it up."

As they continued to chat about their interests and hobbies, it was clear that their friendship had only grown stronger over the years. They may have taken different paths in life, but their shared love of discovery and justice had always brought them together.

And as they prepared to tackle their next case, they knew that they could count on each other to always have their backs.

As they worked together, they found themselves growing closer, their shared passion for justice and their deep respect for each other's skills bringing them together. Eventually, they were able to solve the case, bringing the criminals to justice and saving countless lives in the process.

Years flew by, and Hiro and Yui's paths diverged, taking them down different but equally impressive paths. Hiro had earned a reputation as a leading figure in the scientific community, dedicating himself to unraveling the mysteries of the universe. Meanwhile, Yui had become a skilled detective with a specialty in investigating cases involving the supernatural.

Despite their busy schedules, Hiro and Yui made sure to stay in touch, meeting up whenever they could to share their latest discoveries and catch up on each other's lives. They had never forgotten the strange occurrences from their high school years, and their determination to uncover the truth only grew stronger with each passing year.

But even as they pursued their separate careers, their friendship continued to flourish. They shared a deep respect and admiration for each other's talents and dedication, and their conversations were always filled with lively debates and intellectual banter.

Some had speculated that Hiro and Yui were more than just friends, given their close bond and mutual admiration. However, Hiro had been deeply scarred by the loss of his sister and crush during their high school years, and had thrown himself into his work as a way to cope with the trauma.

Despite the passage of time, the memory of their missing classmates still haunted Hiro and Yui. But they remained committed to finding the truth, no matter how long it took. And with their combined expertise and unyielding determination, they knew that one day, they would uncover the answers they had been seeking for so long.

But one fateful evening, the two met up at a bar to discuss their latest findings. Hiro looked weary, as if he hadn't slept in days, while Yui's expression was grim.

"It's been twenty years, and we still haven't found anything concrete," Hiro said, taking a sip of his drink.

Yui nodded. "I know. But we can't give up now. We owe it to our friends to keep searching."

Hiro said of handily “do you remember what we said after the graduation”

“Of course I do,” replied Yui while drowning herself with whiskey.

As the graduation ceremony came to an end, Yui and Hiro found themselves standing alone outside the school gates. The sky was grey and overcast, casting a gloomy shadow over everything. The wind was cold and bitter, blowing through their hair and clothes, reminding them that summer was over.

Yui looked around, feeling a deep sense of sadness in her heart. She couldn't shake the feeling that something was wrong, that they were missing something important. She turned to Hiro, hoping he could reassure her.

But Hiro's face was grim, his eyes staring off into the distance. He looked like he was lost in thought, as if he was thinking of something he didn't want to share.

"What's wrong?" Yui asked, placing a hand on his shoulder.

Hiro shook his head. "It's nothing. Just thinking."

"About what?" Yui persisted.

Hiro sighed heavily, as if the weight of the world was on his shoulders. "I can't shake the feeling that something's not right," he said finally. "That there's more to what happened to our classmates than what we know."

Yui felt a shiver run down her spine. She had the same feeling, but didn't want to admit it. "What do you mean?"

Hiro looked at her, his eyes filled with sadness. "I don't know. It's like they just disappeared without a trace. No one saw or heard anything. It's like they never existed."

Yui felt a lump form in her throat. She knew that feeling all too well. "Do you think it has something to do with the strange occurrences we experienced during our high school years?"

Hiro nodded. "I do. I think there's a connection. And I'm going to find out what it is."

Hiro and Yui's conversation was interrupted by a deafening crash, and the ground shook beneath their feet. Before they could react, a truck smashed through the wall of the bar, hurtling towards them at breakneck speed.

Yui's training as a detective kicked in, and she instinctively reached for her weapon. But the impact was too sudden and too violent, and there was no time to react. The truck slammed into them both, crushing them instantly and sending debris flying in every direction.

The once-bustling bar was now a scene of chaos and destruction, with people screaming and running for cover amidst the wreckage. But for Hiro and Yui, there was no escape. The two friends, who had spent so many years pursuing the truth and helping others, were gone in an instant.

The news of their tragic deaths sent shockwaves through the scientific and law enforcement communities, and their colleagues mourned their loss with heavy hearts. But for those who knew them best, Hiro and Yui would always be remembered as two brilliant minds and kind-hearted individuals who had dedicated their lives to making the world a better place.

As their bodies lay lifeless on the ground, emergency services rushed to the scene. The police were quick to arrive, and a detective soon approached the area, taking note of the wreckage and the two bodies.

He crouched down beside the two, "What happened here?" he asked, looking up at the other patrons who had survived the crash.

One of them, a young man with a cut on his forehead, stepped forward. "A truck just plowed into the bar," he said, his voice trembling. "It happened so fast, we didn't even have time to react."

The detective scribbled something down in his notebook before turning to another officer. "Secure the area and take witness statements," he ordered, "We need to get to the bottom of this."

As the investigation continued, it became clear that the truck driver had lost control of the vehicle due to a medical emergency. But for Hiro and Yui's families and friends, it was a devastating and tragic end to their long search for answers.

Their legacy, however, lived on. Hiro's research and Yui's investigations had inspired many others to pursue the truth behind the supernatural, and their determination to never give up on their missing classmates had left a lasting impact on all who knew them.
