Motohama: Multiverse Chat Group

A gentle breeze ruffled the curtains of Motohama's modest bedroom as he stirred awake to the buzzing of his alarm clock. The morning sunlight filtered into the room, revealing a surprisingly ordinary sight. Posters of anime characters from various popular series—the kind you'd expect a typical otaku to have—lined the walls. His well-worn futon, with its faded sheets, gave off the vibe of a high school boy's life that existed somewhere between carefree days and the dread of exams. Yet, in truth, Motohama's heart raced with excitement. This was no ordinary day. For he was not merely the bespectacled side character from the High School DxD universe known for his lecherous ways and comedic relief moments—he was a reincarnated soul from Earth. And just yesterday, his new existence had become a startling reality.

Confusion mingled with a flutter of thrill in his chest as he sat up and stretched. He recalled how he once lived as a perfectly normal fan of anime, reading manga and fantasizing about stepping into the grand worlds of his favorite characters. That mundane life had ended in a blink. He had no memory of how he died, only that he'd awakened in the body of Motohama from the High School DxD series—Issei's perverted friend. At first, he could barely believe his surroundings, his mind screaming that he must be dreaming or stuck in some elaborate hallucination.

But dream or not, this second life came with an unexpected perk: a mysterious chat group system. A glowing, translucent interface had materialized before him the moment he realized his reincarnated identity. At first, the interface had displayed only a brief welcome message—some nonsense about "Linking new user to the Multiverse Chat Group." Then it showed the names of individuals from multiple anime worlds that he used to revere, along with a quest log.

Kazuma, Kamijou Touma, Emilia, Emiya Shirou, Fujiwara Chika, Kanae Kocho. The mere list of their names was enough to make any anime enthusiast scream in delight. This group, which connected him to heroes from different dimensions, was apparently real. He hadn't quite processed the significance until the system assigned him his first mission and gave him the so-called Starter Pack. It was all so overwhelming—the words 'Super Saiyan Transformation' and 'Son Goku's Techniques' practically jumped off the screen.

"Me...Super Saiyan?" he muttered under his breath. The improbability of such a gift in a world already brimming with devils, angels, and dragons was surreal. Yet the system had insisted it was his welcome bonus, a cheat-like advantage for a reincarnator. It almost felt too grand. Clutching the transformation token in one hand, he'd felt an intense energy flood his veins, as though something ancient and powerful now slumbered within him, ready to awaken at will.

He rose from bed, heart pounding with anticipation. "If this is real, then everything in my life has changed," he breathed. A part of him worried about messing with the established plot of High School DxD. Another part, though, was positively thrilled: he had always liked side characters who grew strong. If Issei was the Red Dragon Emperor, well, he, Motohama, was now a cunning strategist with a chat group that spanned worlds. Maybe, just maybe, it was his time to become someone greater than a comedic afterthought.

Gathering in the Chat Group

Still groggy, Motohama willed the chat group interface to appear before his eyes. The translucent screen shimmered as lines of text scrolled upward, reminiscent of an app chat window. The group name flickered: Multiverse Chat Group.

A new wave of messages had poured in while he slept:

Kazuma: "Seriously, I can't believe this. A new mission just popped up. Something about a collaboration with a new member from another dimension? I was hoping to laze around today…"

Kamijou Touma: "I'm in the middle of dealing with some trouble in Academy City, but I can step away if needed. My luck is always questionable, though, so hopefully this mission goes smoothly."

Emilia: "I'm excited to meet the new member! Can you introduce yourself properly soon?"

Emiya Shirou: "If you need any help, especially with forging or strategy, I'm here. Let's do our best to keep everyone safe."

Fujiwara Chika: "Hey, hey, if we're meeting in that big headquarters, we should totally do a group dance game! Or maybe host a dinner party. Let's keep it fun!"

Kanae Kocho: "Greetings, new member. I look forward to fighting side by side if needed. Also, I can brew a nice pot of medicinal tea if any of you have had a rough day."

Even though each of these individuals lived in their own distinct world, the system had revealed that there was a special dimensional space—an entire separate world as large as Earth—where they could gather physically. In that parallel world, a sleek skyscraper towered above the cityscape, shining like a beacon in the middle of a futuristic metropolis. That skyscraper was the official Chat Group Headquarters. From the top floors, members could access advanced training rooms, libraries, mission briefings, and all sorts of resources provided by the system. It was reminiscent of the grand guild halls in RPGs, but on a scale beyond anything a single fantasy realm could have produced.

Motohama typed a timid greeting:

Motohama: "Hello, everyone. My name is Motohama… And, well, this might sound weird, but I'm from High School DxD. I just joined the chat group yesterday."

His message soared into the chat, and within seconds, a flurry of responses arrived.

Kazuma: "DxD, huh? That means devils, angels, fallen angels… quite a dangerous world you're in. Good luck, buddy."

Kamijou Touma: "So you must be dealing with the supernatural. If you need an extra hand, I can always punch some sense into your enemies."

Emilia: "Welcome, Motohama. Don't worry if you're new. We'll help you adapt!"

Emiya Shirou: "We stand together. That's what heroes do, right?"

Fujiwara Chika: "Aw, a new friend! Let's do a big welcome party!"

Kanae Kocho: "It's nice to have you with us. If you are ever stressed, just let me know. I've got remedies to keep you calm."

The warmth in their words dissolved any lingering doubt. Despite the chaos of crossing worlds, they exuded a welcoming aura, each with distinct personalities shining through the text. In another life, Motohama would have fainted from joy to see these characters interacting like this. Yet now, he was part of their circle—he was responsible for forging bonds, accomplishing missions, and maybe rewriting his place in a world overshadowed by devils and dragons.

The First Mission

Motohama clicked on the system's mission tab out of curiosity. A new objective flashed:

Mission: Attend Kuoh Academy's Classes Description: As a newly awakened reincarnator, you must maintain your life as a regular student in High School DxD while balancing your chat group responsibilities. Fulfill this day's classes without arousing suspicion and complete a minor quest: discover signs of supernatural activity around campus.

The reward? Ten chat group credits and a small booster pack that could be used to buy items from the group's store. It was a simple mission, more about reacclimating to daily life than taking on big baddies. The system's approach made sense—no need to toss him into a cosmic war on day one. Still, his heart hammered at the thought of scouting supernatural happenings at Kuoh Academy, the very ground zero where Issei's entire story began.

He also noticed a note appended beneath the mission:

"Bonus: If you manage to subtly use Super Saiyan or Goku's techniques while avoiding detection from devils or humans, extra credits will be awarded."

He nearly choked. Was that even possible? The moment golden ki burst around him, Rias Gremory herself might swoop in to investigate. The mere thought of devils discovering his newfound abilities spiked his anxiety.

He typed in the chat group:

Motohama: "First mission is basically to attend school and investigate supernatural stuff. Piece of cake, right?"

Kazuma: "Heh, better than having to fight a Demon King. If all you have to do is keep your head down, that's easy."

Kamijou Touma: "Careful. In my experience, trouble finds you whether you look for it or not."

Fujiwara Chika: "Ganbatte! I believe in you! School life can be tough, but think of all the fun you can have, too."

Their encouragement fueled Motohama's determination. If his first day had taught him anything, it was that while he possessed cheat-like powers, he wasn't suddenly unstoppable. The system's guidance was incremental, allowing him to adjust to his new life step by step.

A Day at Kuoh Academy

Donning the Kuoh Academy uniform felt strangely exhilarating. He looked at himself in the mirror, adjusting the collar of his black blazer. No longer was he just an afterthought side character. He was someone with the potential to stand out.

As he walked through the school gates, he recognized certain faces—Issei Hyoudou, with his messy brown hair, was greeting Matsuda. The two had that same playful banter about the girls who passed by. Motohama swallowed hard; he had to keep up appearances, so he hurriedly approached them with a casual wave.

"Yo, you guys just get here?" he asked, trying to sound like the old Motohama. The Motohama in canon would have joked about peeking on girls in the locker room or calculating the bust sizes of passing upperclassmen. The new, reincarnated Motohama found such behavior embarrassing, but he didn't want to act out of character right away.

Matsuda laughed. "We were just talking about how we might get lucky this year. Springtime of youth and all that. But you know how it is—this school's got some real hotties."

"Yeah…" Motohama forced a grin, though his mind was already drifting. He scanned the courtyard discreetly, trying to sense anything unusual. According to the original storyline, devils roamed these very halls incognito, and some of them were extremely powerful. He realized, with a jolt, that he might even pass a near-immortal being in the hallway without knowing it.

Throughout the morning classes, he found it difficult to concentrate. His new system pinged softly at intervals, updating him whenever a chat group member posted something. Meanwhile, the teacher's droning voice about algebraic formulas was practically a lullaby to the rest of the class. Girls whispered, notes were passed, and Issei probably spent more time eyeing the girls than solving equations.

During a break, Motohama excused himself and wandered toward an empty stairwell. Heart pounding, he tried to sense the Ki that was supposedly unlocked by his Super Saiyan ability. He reached inward, feeling for the spark of energy. The moment he concentrated, he felt warmth blossoming in his abdomen—energy swirling, latent, waiting to be released.

A swirl of golden aura flickered around him, but he quickly clenched his fists, forcing it down. He dared not transform fully; it would be like sending a flare into the sky, especially if any devil or fallen angel was sensitive to energy fluctuations.

Focus, he reminded himself, I should test Goku's techniques carefully. Maybe after classes, he could sneak away to test the Kamehameha or the Instant Transmission in secret. Just imagining it sent a thrill down his spine. Would he blow out an entire wall by accident?

A Subtle Supernatural Presence

The system mission demanded some detective work, so Motohama spent his lunch break strolling the corridors. Keeping an ear open, he listened for rumors about ghosts, suspicious occurrences, or anything that might hint at supernatural infiltration. But no one seemed particularly rattled.

That was, until he walked by the Occult Research Club room. A subtle pressure pressed against him, like stepping into a pocket of heavier air. He recognized the tall figure of Kiba Yuuto leaning casually near the entrance, wearing a polite smile as if he were simply guarding the place.

Their eyes met. Motohama felt a chill run down his spine—a mixture of nervousness and that subtle intimidation that Kiba radiated. Inside that room, Rias Gremory and Akeno Himejima must be going about their business. The protagonist Issei had yet to be pulled into their world fully, but the seeds were there. The balance of the canon timeline hung precariously.

Kiba tilted his head. "Motohama, right?" he said with a perfectly polite intonation. "You don't usually wander here. Did you need something?"

"Oh, just…looking for a quiet place to eat," Motohama lied, trying not to stammer. "Thought the club rooms might have some free space."

Kiba's smile didn't falter, but his eyes seemed to assess Motohama for a moment too long. Then he gestured. "I think the library would be quieter. The Occult Research Club is a bit busy today."

"Right, thanks. Good idea."

Motohama walked away quickly, thoughts racing. He had felt it—the faint tingle of devilish power. No wonder the mission wanted him to remain inconspicuous. If Kiba, Rias, or Akeno grew suspicious of him, it could complicate the plot immensely. The system had probably foreseen that his life at Kuoh Academy would be a delicate balancing act of staying under the radar.

A Quick Dip into the Chat Group World

Classes ended without further incident, leaving Motohama free for the day. He scrolled through the chat group messages again:

Kazuma: "Hey, newbie, how did your day go?"

Kamijou Touma: "Tell us if you found anything supernatural."

Motohama: "Found a bit of devil presence, but all good so far. I don't think they suspect me."

Emilia: "Phew, that's good. Let's celebrate your first successful day!"

The system chirped, letting him know that part of his mission was complete: Attended a day of classes. The next part read: Investigate or confirm any devil activity without exposing yourself. He had done some minimal scouting, so it probably counted.

To confirm it, though, might require a more thorough check. But how?

Then the chat group displayed a small icon urging him to visit their shared dimension: Would you like to enter the Chat Group World now?

He stared at it, heart fluttering. According to the welcome tutorial, he could teleport into that dimension to meet members face-to-face, train, or consult the group's resources. Time there ran parallel to his world, but he could come and go with little delay.

"Let's try it," he whispered.

He willed the interface to transport him, and a faint swirl of light consumed his vision. The next moment, he found himself standing in a futuristic plaza. The sky overhead was a bright azure, and the air felt crisp and clean, reminiscent of a newly minted city. Gleaming buildings of various architectural styles lined the horizon, but one structure dominated the skyline: an enormous, skyscraper-like tower with sleek glass walls that caught the sunlight.

"So this is the Chat Group World…" Motohama murmured, scanning his surroundings in awe. A neon sign reading Chat Group HQ hovered near the tower's entrance. Strangely enough, the plaza was bustling with random NPC-like figures—citizens generated by the system to make the dimension feel lived-in.

It didn't take long for him to spot Kazuma, who was easy to identify from his adventurer's outfit (though he'd apparently replaced some medieval pieces with more casual attire). Kamijou Touma was there too, sporting his signature spiky hair, while Emilia hovered by the entrance, elegantly dressed in her typical white and purple ensemble. Emiya Shirou, Fujiwara Chika, and Kanae Kocho were absent for the moment, perhaps busy in their own worlds.

Kazuma lifted a hand in greeting. "Motohama, right? Not bad for a newbie. Only a day in and you're able to cross into this dimension. Did you come to train or just to check it out?"

"Both, I guess," Motohama admitted, feeling a bit starstruck. He was standing before Kazuma and Touma, two comedic yet heroic figures in their own realms.

Touma grinned. "We can show you around if you'd like. This tower has everything—training rooms, dorms, even a cafeteria. Chika insisted on a music and dance hall up on the tenth floor, so if you hear random singing, that's probably her."

Before Motohama could respond, Emilia approached with a warm smile. "It's lovely to meet you, Motohama. I'm Emilia. You're a high school student, right?"

He nodded, momentarily speechless. "You're, uh, from Lugnica, the kingdom from Re:Zero, if I'm not mistaken."

Her eyes widened in pleasant surprise. "You know of my homeland?" She laughed softly. "Of course, you do. The group told me that some of our worlds are actually stories in other realms."

Kazuma interrupted with a sly grin. "She's the best half-elf you'll ever meet."

Touma snorted, then patted Motohama on the back. "Anyway, we were discussing a potential training session. Why not join us? The tower has specialized gravity rooms and simulated environments. Perfect for practicing your new 'Super Saiyan' thing."

Excitement and nervousness tangled in Motohama's gut. "I guess I should. I've never, you know, powered up fully."

Kazuma shrugged. "Better to do it here where you can't blow up your school."

With that, they set off through the sleek, automatic doors into the HQ tower. The lobby was futuristic—a shiny, spacious reception area with digital screens displaying the day's missions, group rankings, and general announcements. A few other chat group members—NPC visitors or lesser-known cameo characters—mulled about, but the place wasn't crowded. Kazuma led them to an elevator, pressing a glowing panel for one of the top floors.

As they ascended, Motohama's heart pounded. The system had gifted him a legendary transformation. Could he really achieve it on command? Goku's techniques were no joke, either: the Kamehameha wave, Instant Transmission, the Spirit Bomb. He recalled the first time Goku turned Super Saiyan, how it marked a moment of epic transformation in Dragon Ball. Now, here he was, about to attempt something similarly monumental.

Testing Super Saiyan

The training room was vast, with reinforced walls that shimmered faintly. Kazuma explained that each area could adapt to different power levels.

Touma stood at the edge, crossing his arms. "Try powering up, but do it slowly. We don't know how this world's environment will react. The system says it's stable, but better safe than sorry."

Emilia watched curiously, perhaps mentally comparing Motohama's energy-based transformation with her own magic abilities.

Motohama inhaled. He closed his eyes, focusing on that warm, pulsing energy near his core. He reached for it, coaxing it outward. A flicker of power coursed through him, and golden sparks began dancing around his body. His hair fluttered, then in a sudden rush, it turned a brilliant gold. His eyes shifted to a turquoise hue, and a powerful aura flared to life around him. The shockwave rattled the training room floor.

"Woah!" Kazuma exclaimed, shielding his face from the blast of energy.

Touma's eyes widened. "So this is the famed Super Saiyan state…"

Emilia smiled, though she looked a bit intimidated. "It's quite intense, isn't it?"

Motohama's senses exploded in clarity. Every breath he took felt like pure electricity fueling his muscles. He sensed the flow of energy in the room, the quivering of the walls, the subtle presence of his companions. With a single step, he felt as though he could sprint across a city in the blink of an eye.

This is amazing, he thought. He turned his head, noticing that the transformation demanded a certain level of emotional intensity to sustain. He remembered from the anime that anger or a strong desire to protect often triggered it. For him, the trigger might have been the excitement of forging a new destiny. Yet, he reminded himself that raw power meant little without skill.

He turned to the others. "I—I did it. I'm actually a Super Saiyan."

Kazuma let out a low whistle. "Color me impressed. Try throwing a punch at that target." He pointed to a large training dummy near the far wall.

Motohama nodded, rearing back his fist. He threw a punch, and to his astonishment, a blast of wind pressure tore across the room, hitting the dummy with a thunderous boom. The dummy flew off its stand, slamming into the wall and cracking it.

"Oops," Motohama gasped, powering down abruptly. The golden aura vanished, his hair returning to its normal color. Anxiety flashed across his face. "I didn't mean to break anything!"

Emilia giggled. "Don't worry. It's designed to handle that. Though you might want to tone down the power a bit."

Touma approached the hole in the wall, examining the damage. "Impressive," he muttered. "But yeah, controlling your output is going to be crucial if you don't want to draw unwanted attention in your world."

Motohama exhaled, exhaustion setting in. Even that brief transformation had drained more energy than he expected. "No kidding. If I did that at school, I'd blow the entire cover."

Kazuma patted him on the back. "Well, that's what the chat group is for. We share tips, help each other train. You'll get the hang of it."

A Glimpse of the Future

After some time resting in the lounge area, sipping tea that Emilia prepared (with a slightly sweet aroma), Motohama felt more relaxed. Yet, he couldn't shake a nagging worry: High School DxD was about to escalate with devils, fallen angels, and gods. When the likes of Rias, Akeno, and eventually Azazel got involved, would his identity be discovered?

And what of the chat group missions? They might thrust him into other worlds' conflicts, or bring those conflicts to his own doorstep. The reward system was enticing, sure—he could unlock more techniques, maybe even cross into advanced forms of Saiyan power. But the stakes would be sky-high.

Touma, sensing his apprehension, rested a hand on his shoulder. "You look worried. Is something on your mind?"

Motohama hesitated. "Just… the future. My world has intense storylines. Heavenly dragons, the apocalypse if things go wrong."

Kazuma scoffed lightly. "Join the club. My world had a Demon King. Touma's deals with magic gods and super-intelligent beings. Emilia contends with witches and curses. Conflict is inevitable, but we have this chat group for a reason. Don't shoulder everything alone."

Emilia nodded. "Exactly. We'll stand by you, even if it's across worlds. That's part of the system's plan, right?"

A warmth spread in Motohama's chest. This was more than just a random cheat system. It was a network of allies, forging bonds that transcended dimensions. He recalled how lonely the original Motohama seemed—always overshadowed by bigger events, overshadowed by Issei's adventures. Now, he had the chance to become more than a background character.

A soft ping from the system startled him. Mission updated: Investigate supernatural presence at Kuoh Academy. Reward: +10 credits. The system must have recognized he'd gleaned enough info from his interactions near the Occult Research Club to count as completion.

"That's that," he said, glancing at the pop-up. "So the first mission is done."

Kazuma grinned. "Great. Now you can buy yourself a fancy item from the store. Might I recommend a luck talisman? Because I sure wish I had one."

Touma smirked. "Says Mr. NEET. Don't listen to him, Motohama."

Emilia smiled, sipping her tea. "Take your time deciding what to buy. Some items might help you hide your power level, for example, or mask your aura."

That suggestion sparked Motohama's interest. "A mask for my aura… that would probably solve my biggest problem right now."

He opened the system store tab in the corner of his vision. A dizzying array of items scrolled past: potions, magical artifacts, skill books. Some cost thousands of credits, way beyond his budget. But a lesser item to conceal Ki or demonic signature might be within reach.

Sure enough, he found something affordable: Minor Concealment Talisman. It only cost 10 credits, exactly the amount of his first reward.

He purchased it on a whim, feeling a subtle shift as if an invisible shroud settled over him. The system displayed a message: Your power signature will now be harder to detect by those at or below High-Class Devil level. (Caution: does not work against god-level entities.)

Relief washed over him. Maybe now he could avoid drawing suspicious stares from Rias's peerage if he accidentally let out a spark of Saiyan energy.

Hope in the Journey

As evening approached, Motohama bid farewell to Kazuma, Touma, and Emilia, promising to drop by the HQ again soon. He returned to his own world, stepping into his bedroom with a swirl of light.

Collapsing onto his bed, he let out a long sigh. It had been one day, and so much had happened. He was living a dream—a chat group bridging worlds, a mythical transformation at his fingertips, and a plot-laden high school life swirling around him. Questions still loomed, like how he'd navigate the main story arc of High School DxD without upending fate, or how powerful foes might appear from other worlds.

But a sense of optimism beat steadily in his heart. He wasn't alone. He had an entire building of friends waiting in a dimension all their own. He had missions to guide him, forging him into something greater. And for perhaps the first time, Motohama felt truly important.

"A person from Earth reincarnated as a side character in High School DxD," he murmured with a small smile, pulling the blanket over himself. "Armed with a Multiverse Chat Group and Saiyan power. The possibilities are endless."

His phone buzzed. Another mission notification. He peeked at the screen:

New Daily Quest: Practice Goku's Techniques without alerting Kuoh Academy. Reward: 5 credits, random small consumable.

He set his phone aside, eyes drifting shut. Tomorrow, he'd test a Kamehameha wave somewhere secluded. Tomorrow, he'd attend classes again, feigning ignorance while devils walked the halls. Tomorrow, he'd chat with Kazuma, Touma, Emilia, and maybe meet Emiya Shirou, Fujiwara Chika, or Kanae Kocho. Tomorrow, he would keep pushing himself further than any side character had a right to go.

He drifted to sleep, mind brimming with hope and adventure. Because for all his faults, for all the comedic hijinks that came with being Motohama, he wasn't just a side character anymore. He had a story—and a power—all his own.
