What is this Dimensional Chat???

Kuoh, Japan

Satria walked into the living room, observing the pristine condition of the house.

"Not bad. Must be a rich family," he muttered, his voice echoing slightly in the vast empty space. "But honestly, what a waste. This whole mansion for one person? What were they thinking, leaving this kid alone here?"

The loneliness of the house gnawed at him, the vastness amplifying the silence.

He sighed and began exploring. Checking every corner, he examined the bedrooms, the guest rooms, the bathrooms, the garden, and even the storage room. Everything was in perfect order, a clear sign of wealth but lacking the warmth of a lived-in home.

"All good," he said. "Now let's see how much cash I've got."

Satria pulled out his phone and logged into the bank app. A quick check showed a balance of 124,000¥. 

"Let's convert this… Wait, what?! 14 million rupiahs?!" He stared in disbelief. "When I was this kid's age, my mom barely gave me 15-20 thousand a day for pocket money!"

Shaking his head, he made his way to the kitchen. 

•

In the kitchen, Satria opened the fridge to inspect its contents.

"Let's see what we've got—" His voice cut off as the door swung open.

Inside were two eggs on the verge of rotting, a carbonated drink that turned out to be beer, and some frozen food nearing expiration.

"What the hell? What are this kid's parents thinking? They send money but can't even make sure there's decent food?!"

He checked the cabinets. Dusty cookware, a few instant ramen cups, and not a single grain of salt or sugar to be found.

"Wow… This kid doesn't even cook. He's surviving on microwaved garbage."

Satria groaned. "At least they send money, I guess. Let's see what else this place has to offer."

Back in the study, Satria began flipping through photo albums.

The family looked picture-perfect: a father, a high-ranking businessman; a mother... Who know? Their photos were like something out of a corporate magazine or a fantasy story.

But something felt off.

As he flipped through the pages, he noticed a pattern. The family photos stopped when the boy was in elementary school. From then on, nothing.

"Yup. Something's definitely wrong with this family," Satria murmured, his unease growing.

A notification popped up on the boy's smartphone.

[I have business in Korea. Take care of yourself. I'll send your pocket money soon and don't call me unnecessarily]

"Wow. So much love in that message." His sarcasm cut through the quiet.

He sighed, stretching. "Alright, time to buy some actual food. Let's check the garage."

Inside the garage, Satria found a sleek car, a sporty motorcycle, and a dusty bicycle tucked in the corner.

"Fancy rides, but no license yet and it's not Indonesia where Elementary School already can ride Motorcycle. Wait! That bad boy is me hahaha! I remember when my mom was very angry with me and dad after I learned to ride a motorcycle from him. Guess bicycle it is."

He pulled the bicycle out and started pedaling toward the nearest supermarket.

As he passed the city park, a loud commotion caught his attention.

"What's that?" He stopped and hid behind a tree to investigate.

In the distance, he saw a black-haired woman with dark, menacing wings killing a brown-haired boy.

"Shit… I'm too late."

His breath caught. The boy looked familiar.

"Is that… Issei?"

He clenched his fists but didn't intervene. It was already too late to help and his new body now weak as fuck!

The woman disappeared, leaving behind a glowing paper. Moments later, two more women—one with vibrant red hair, the other with long black hair—appeared.

Satria's eyes narrowed as he watched the red-haired woman place a chess piece on Issei's chest, healing his fatal wound.

"They're reincarnating him. Figures."

A voice suddenly echoed in his mind.

"Who's there?" Satria froze.

[Relax, boy. We'll talk later. I've been your memories. You're an interesting one]

"Great. Something's inside me now," Satria muttered internally, trying to mask his unease.

[You don't seem too surprise]

"I've had a weird day. Who are you?"

[Fatalis. The Forgotten Black Dragon]

"Never heard of you. How'd you get inside me?"

[Fatalis: Not sure. I was in my resting place when a strange light appeared. Next thing I knew, I was here. Well, it's better than that boring place]

Satria sighed. "Nice to meet you, partner."

[Fatalis: Likewise, boy. And that reincarnated one—he's the host of Ddraig, isn't he?]

"Yeah. A fictional character from my old world. I guess not so fictional here."

[Fatalis: Well, his dream of being a Harem King is pretty ridiculous, but I suppose it works for him]

"True," Satria said, standing up. "Let's get out of here."

•

After buying groceries, Satria returned home and put the bike back in the garage.

He sat on the sofa, deep in thought.

"Three days until I enroll at Kuoh Academy. I need to get stronger. Fast."

Suddenly, a screen materialized in front of him.

[Ding!]

"What the—" He yelped, nearly falling off the sofa.

[You have been chosen as the Admin of the Dimensional Chat Group]

"Dimensional what now?"

The screen continued.

[System initializing in 10 seconds.]

[10… 9… 8…]

watching...

Satria stared at the countdown, baffled.

[0… System ready]

[Create your nickname]

"Alright… call me Shin."

[Nickname confirmed]

A flood of information filled the screen, explaining the chat group's purpose: connecting people from different worlds to help each other, complete quests, and buy skills from a system shop.

He skimmed through it. "Weird, but… could be useful."

Satria blinked at the names on the screen.
