Kaito Yamada thought he was just an ordinary guy. A quiet Japanese student whose world revolved around anime, manga, and video games. Not a loner, not an extrovert—just someone who found solace in the electrifying chaos of High School DxD, a universe brimming with demons, angels, and forbidden power. Secretly, he dreamed of stepping beyond the screen, into that world of danger and desire.
Then, one restless night, everything changed.
Lost in the latest episode, his eyelids grew heavy. A sudden wave of exhaustion pulled him under. When his eyes snapped open again, the world was gone.
The ceiling of his room vanished, replaced by an endless sky — a clear blue dome under a blazing sun. The scent that filled his lungs was unfamiliar, sweet, and strange. Beneath him, soft grass cushioned his body. Towering ancient trees stretched beyond sight. The air thrummed with life he couldn't place.
Dizziness spun him upright. His eyes darted wildly — and froze.
Before him stood an enormous iron gate, embossed with a symbol he knew too well. Beyond it, majestic buildings of unfamiliar design rose against the horizon.
"Koh... Academy?" His voice was a breath, disbelief choking his throat.
Then, a faint azure glow flickered before him. A translucent screen shimmered into view.
[Welcome, user.][Ascension system activated.][Please enter your username.]
Kaito blinked, heart pounding."A system? Ascension system? Am I... dreaming?" He pinched his arm hard. The sting confirmed the impossible — this was real.
"Kaito Yamada," he whispered.
[Username set: Kaito Yamada.][System initializing...][Initialization complete.][Welcome to the High School DxD world.][Note: Appearance optimized for integration.]
A cold shiver ran down his spine.
"Appearance optimized?" Panic twisted his gut. He scrambled toward a nearby window and stared at the reflection.
The face looking back was a stranger's—yet stunningly beautiful. Thick, glossy black hair framed sharp, golden-tinged brown eyes. Every feature sculpted to perfection. His skin was flawless; his body taller, stronger, leaner.
"What… what is this?" He touched his face, awe and fear warring inside. "I look incredible... but this isn't me."
Reality crashed over him: this world was no longer fiction. He was trapped inside it. And he was no longer just an ordinary boy.
His thoughts shattered by approaching footsteps. Two girls emerged from the school gates.
One—long crimson hair, piercing blue eyes—her presence struck Kaito like lightning. Rias Gremory... his heart thundered, but he swallowed the name.
The other—a sleek ponytail of midnight black hair, eyes deep violet, smile soft but knowing. Akeno Himejima, he recalled, forcing calm into his expression.
They stopped, eyes locking onto him. The redhead's gaze sharpened; the other smiled gently.
"Are you a new student here?" the redhead asked, voice smooth but cold.
An alert blinked before Kaito's eyes:[Warning: Revealing unnecessary information may lead to unintended consequences. Proceed with caution.]
He forced himself to breathe, steady his voice.
"Yes. I'm Kaito Yamada. I transferred recently." A polite smile, carefully measured. Natural.
The redhead's eyebrow quirked with suspicion."Transferred here now? I haven't heard of any new students this time of year." Her eyes searched him, as if trying to read a hidden script.
Kaito met her gaze evenly. "It was sudden, for me too. I'm looking for the administration office. Can you help?"
The black-haired girl stepped forward, warmth flooding her smile."Of course, Kaito-kun. It's on the first floor of the main building. We'll show you."
Relief bloomed in his chest. "Thank you both."
"No problem," the redhead said, still curious. "Welcome to Koh Academy."
They walked away, leaving Kaito alone again. He exhaled, tension loosening. He'd passed his first test.
His eyes drifted to a distant club building, then back to the glowing blue screen hovering before him.
Ascension system… DxD world… new appearance... he murmured, voice low but resolute.
This is no longer anime behind the screen.
Dangers awaited. Unknown threats. But beneath the fear, a spark ignited — a thrill he'd never known.
This was his destiny. His world now. Time to live it. Carefully. Fiercely. On his own terms.
