When Ryuya Kurobane came to his senses, he was already standing at the front of a classroom.
"This is the new transfer student who'll be joining our class starting today. Alright, please introduce yourself to everyone."
Beside him stood a chubby, balding teacher. Below, a roomful of students sat watching curiously. Ryuya's expression wavered slightly, his mind still hazy.
Just moments ago, he had been on the street, pulling a little girl out of the way of an oncoming car. He vaguely remembered the screeching of brakes—then a warm light engulfed him.
And the next instant… he was here.
Looking down at the rows of curious faces, Ryuya couldn't help but wonder—
Is this… heaven?
He had saved a little girl's life. It only made sense he'd end up in heaven afterward, right?
"I thought I'd at least see an angel," he murmured, glancing around the room, sighing softly with a strange mix of calm and disbelief.
Everyone—teacher and students alike—stared at him, confused. Someone even snorted with laughter.
"What's this guy on about? Bro, are you still sleepwalking or something?"
The wave of laughter that followed brought Ryuya back to himself. He straightened his posture, trying to process his situation.
Whatever this was, one thing was certain—his consciousness still existed. The question was whether he had been transmigrated or ascended. Hard to say, really… after all, it was his first time dying.
Still, since he was here—might as well adapt.
He lifted his head, flashing a well-practiced, almost mechanical smile he'd perfected countless times before.
"My name's Ryuya Kurobane. Nice to meet you all."
A perfectly ordinary self-introduction. In fact—too ordinary.
Several students immediately lost interest, curling their lips in boredom.
What a dull guy.
Only a few girls perked up, clearly taken by his good looks, but aside from them, everyone quickly turned away.
"Alright then, Ryuya," the teacher said, adjusting his glasses. "You can sit in the back by the window."
With that, he picked up a piece of chalk. "Now then, everyone, take out your textbooks and turn to page 69…"
Still wearing his polite smile, Ryuya walked to the assigned seat. Once he sat down, the smile faded, replaced by quiet introspection.
He placed his bag in the desk drawer, then checked his pockets—phone, student ID, two keys, and some paper bills.
His eyes landed on the bills first. The currency was unfamiliar—denominations of one thousand, three hundred, and fifty, with coins marked fifty. Judging from the values, it seemed roughly equivalent to Japanese yen.
He flipped his phone around, using the screen's reflection to check his face.
It was his own. The same sharp features, same confident expression.
"Good," he nodded with satisfaction. "Still handsome as ever."
Unlocking the phone with his fingerprint, he was greeted by a lock-screen photo—himself on a bicycle, smiling brightly at the camera.
He stared at it for two seconds.
Something felt off.
Since when do I smile like that?
Shaking his head, he tapped twice and changed the wallpaper.
His student ID read: Kuoh Academy, Class 2-1. An address was also listed below—so that explained the two keys.
Ryuya fell silent in thought. Judging from all this, his soul had probably transferred into an alternate version of himself in another world.
So… there really is life after death.
He let out a quiet sigh, pushing away the flood of emotions.
All things considered, this wasn't a bad outcome. At least he'd gotten a fresh start.
Just then, from the corner of his eye, he noticed two people beside him staring his way. Pretending not to notice, he casually turned his head—and froze for a split second.
Two breathtakingly beautiful girls were indeed looking at him.
The one on his left had long, flowing crimson hair and clear, commanding eyes. Her beauty held a cold, mature allure—almost bewitching. It was the kind of beauty that could pull your gaze and refuse to let go.
The girl beside her wore her glossy black hair in a high ponytail. Her delicate face carried a gentle smile, exuding warmth and elegance. Though her charm was softer and more restrained, she was no less stunning—and her figure even surpassed the redhead's.
Each was captivating in her own way, a perfect balance of grace and temptation.
Ryuya met their eyes for two seconds before politely averting his gaze.
Pretty girls, he thought to himself. Probably just curious about the new transfer student.
He had no idea that Rias Gremory and Akeno Himejima had already taken notice of him for a far deeper reason.
From the moment he entered the classroom, the two devils had sensed it—
A massive power sleeping inside him.
A power so immense it made even high-class demons shudder.
There was no doubt about it—
It was the aura of a Sacred Gear.
Rias and Akeno exchanged a brief glance, silently withdrawing their gazes as if nothing had happened.
The rest of the school day passed uneventfully.
Ryuya stopped by the school's security office, claiming that his bicycle had gone missing. After checking the surveillance footage, he successfully found it and rode home—to this world's version of his home.
Unlocking the door, he was greeted by a slightly messy room.
Ryuya pressed his lips together, his eyes instinctively drifting toward the small household shrine on the wall.
There, framed in black and white, were the portraits of a middle-aged couple.
From his earlier chat with a teacher, he had already learned—this world's version of his parents had died in a truck accident.
That damned truck.
It took my parents again.
This grudge… I'll remember it.
Expressionless, Ryuya walked into his bedroom. It was simple in decoration, with a computer sitting on the desk. Then he noticed the trash bin—stuffed full of crumpled tissues. His eyebrow twitched.
Opening the computer, he immediately found a hidden folder containing over a hundred "study materials." Ryuya couldn't help but chuckle.
He clicked a few at random—titles like Academy Stillness, Widow's Solitude, Convenience Store Manager, Defense Squad…
He winced.
Good grief… so my past self was a full-blown otaku.
After cleaning up a bit and turning off the computer, Ryuya began exercising. A while later, drenched in sweat, he took a shower and lay on his bed—naked, arms behind his head, staring blankly at the ceiling.
Everything at school today had been peaceful.
A few guys had come over to chat, and a few girls had tried to talk to him—but he handled them all with the same polite, measured smile.
Whether it was school or society, it was all the same—the so-called "atmosphere."
Ryuya had no interest in playing along with those shallow social games.
Still, one couldn't act too detached; that only made others push you away.
And being an outcast was… troublesome.
So, he had learned to fake it—to keep people at just the right distance.
Not too close, not too far.
That way, he could live quietly without ever really joining the crowd.
Yes, he thought—it was a comfortable way to live.
At least, that's what he thought.
Until two days later—
He suddenly got a girlfriend.
To be exact, a girl he didn't even know suddenly confessed to him.
From her brief words, Ryuya could tell that not even his previous self knew her.
Her name was Yūma Amano—a sweet, soft-spoken high school girl with a cute face and innocent charm.
That evening, under the orange glow of sunset, the girl stood on the bridge, fidgeting nervously as she faced him.
Her cheeks were pink, her voice trembling as she gathered all her courage to speak.
"U-Um… my name is Yūma Amano. I… I saw you at the school gate yesterday, and since then I just… I can't stop thinking about you. So, um… c-could we… try going out?"
Her words were hesitant and shy, her gaze darting away, too embarrassed to meet his eyes.
Ryuya was stunned.
Seriously? Even like this, someone's confessing to me?
What was going on here?
Had heaven really been moved by his earlier sacrifice? Was this girl… an angel sent down as a reward?
The thought almost made him laugh. But inwardly, he wasn't the least bit convinced.
According to Yūma, it was "love at first sight." That she'd been drawn to him from the moment she saw him.
Love at first sight, my ass.
"Let's go out"? More like "let's sleep together." At least that would be more believable.
Did pure love even exist anymore? He doubted it.
Ryuya maintained his usual gentle smile, but inwardly, his mind was sharp—cold, even.
A beautiful JK girl confessing out of nowhere? Impossible. Absolutely impossible.
There had to be a reason. Something she wanted from him.
He needed to find out why she was approaching him.
After all, he was alone now.
Aside from his parents' 280-square-meter house and the forty million yen insurance payout from their deaths, he had nothing left.
Surely she wasn't after him physically… right?
If that's the case, please—no need for all this roundabout nonsense.
I can just lie down and get it over with!
With that cynical thought in mind, Ryuya decided to play along—to test the waters.
Outwardly, he feigned surprise and happiness, and accepted Yūma's confession on the spot.
And just like that, they became a couple.
"Then… tomorrow's our day off," Yūma said with a radiant smile, her eyes sparkling with hope. "Ryuya, how about we go shopping together?"
Her big, watery eyes shimmered with expectation and a hint of playful charm.
Ryuya responded with a gentle smile.
"Sure. Tomorrow it is—don't be late."
"Mm!!"
Her face lit up with joy.
"Be careful on your way home," he added, smiling softly as he reached out and tousled her hair.
That tender smile of his made Yūma blush deeply.
She walked away, glancing back at him every few steps—clearly the image of a girl completely lost in the throes of first love.
Ryuya kept that gentle smile on his face, watching Yūma's silhouette grow smaller and smaller in the distance.
And the moment she completely disappeared from sight—his warm smile vanished too, replaced by a cold, expressionless face.
He stood there silently for a few seconds, replaying her words and actions in his mind, but nothing stood out as suspicious.
Eventually, he sighed, giving up on overthinking it. He cast one last, meaningful glance toward the direction she'd gone, then turned around and left.
Let's see what exactly this girl is up to.
Not long after Ryuya was gone, a petite, adorable girl with short white hair suddenly appeared in the same spot.
She gazed in the direction he had left, then took out her phone. The name displayed on the screen was President Rias.
"Hello, Koneko. Did you find anything?" came Rias Gremory's calm voice.
"As you suspected, President," Koneko Toujou replied softly, "that Fallen Angel is preparing to make a move on him."
"Good work. Come back now."
"Understood."
Koneko ended the call but stayed there for a moment, frowning slightly.
She couldn't quite put her finger on it—but something about Ryuya's demeanor had felt… unsettling.
There was a cold, almost frightening aura beneath that gentle exterior.
---
The next day.
Ryuya woke up early, washed up, and got ready to head out—for that so-called "date" Yūma Amano had arranged.
As he walked past the living room toward the door, he suddenly stopped mid-step.
After a moment's thought, he turned around, walked back to the coffee table, and picked up a fruit knife lying there.
He slid it into his pocket.
Sure, maybe carrying a knife to guard against a high school girl was a bit excessive… but to Ryuya, a beautiful stranger suddenly confessing her love was far more suspicious than it was romantic.
This smells like a scam. Or maybe a setup. Or worse—school bullies.
He imagined the scenario vividly:
The moment he followed her somewhere quiet, a group of her accomplices would jump out—threatening, demanding money, the usual crap.
Yeah, that sounded about right.
He admitted to himself he might have a touch of paranoia.
Still, even if this girl was mixed up with some shady people, how bad could it be? She was just a high schooler, after all.
And if, by some miracle, Yūma really was a pure-hearted girl who just wanted an innocent high school romance…
Then he'd find a way to make it up to her later.
He'd take care of her properly.
With that thought, Ryuya pressed his lips together, got on his bike, and rode to their meeting place.
From a distance, he could already see her—Yūma Amano, standing there under the morning light, beautiful as ever, waiting quietly for him.
Stopping his bike in front of her, Ryuya wore an apologetic smile.
"Sorry, Yūma. I'm late." (On purpose.)
"It's okay! I just got here myself."
Her smile was bright and carefree. She didn't seem bothered at all.
Then she stepped forward and wrapped her arm around his. "Let's go!"
"Heh, sure."
Ryuya smiled gently, following her lead as the "date" began.
They wandered around the mall together—picking out clothes for each other, taking a photo booth snapshot, and eating desserts at a nearby café.
Ryuya even bought her a gift: a cute headband.
To anyone watching, they looked like the perfect young couple, laughing and chatting with an easy warmth between them.
Hours passed quickly. Before long, the sun was dipping below the horizon, and the sky turned red.
They eventually left the busy streets, heading toward a quiet, deserted park nearby.
Once inside, Yūma suddenly quickened her pace, stepping ahead of him.
Then, by the fountain, she turned around—smiling sweetly.
"Ryuya, as a memory of our first date… can I ask you for one little favor?"
She clasped her hands behind her back, tilting her head, looking at him with that same soft, endearing smile.
"Of course," he replied calmly—his right hand already resting in his pocket.
Yūma's lips curved into a charming grin… but then, slowly, that sweetness twisted.
Her smile sharpened—cold, cruel.
"—Can you please die for me?"
Ryuya's smile froze. His expression darkened as he instinctively stepped back two paces.
"…What did you just say?"
Yūma's playful demeanor was gone, replaced by a chilling smirk.
She took a step closer.
"I said… could you die for me, right now?"
The instant the words left her mouth, her entire appearance shifted.
Her clothes disintegrated into light, and for a brief heartbeat Ryuya caught a flash of bare white skin—before black garments reformed over her, dark and sinister.
Then, with a snap, a pair of black wings burst open from her back.
In her hand, a glowing sphere of light materialized, quickly forming into a spear crackling with lightning.
Arcs of electricity danced across the weapon, humming with deadly power.
Watching Yūma transform before his eyes into something… inhuman, Ryuya's mind reeled.
A girl—no, a being—with black wings and a thunder spear.
He reached into his pocket, feeling the fruit knife, his thoughts an incoherent spiral of disbelief.
Are you kidding me right now…?
What happened to the normal high school girl!?
What kind of insane world did I end up in!?
