He carried memories that did not belong to him.
The plane descended through low clouds, leaving behind a strip of light that seemed reluctant to let it go. Kaelan pressed his forehead against the window as Japan unfolded beneath him — quiet streets, distant lights, a calm that did not belong to him.
A new country. A new life. A new lie.
The original Kaelan Arverth never got to live it.
The taxi dropped him in front of a small house on the outskirts of Kuoh. He entered. Unpacked in silence.
And then agony tore through his body.
After that — nothing.
Darkness. Silence. Death.
He never woke up.
The Kaelan standing here now was someone else.
A normal student. A fan of video games, light novels, quiet routines. Walking home from work with headphones on, scrolling through a story on his phone—
— when a white light swallowed him whole.
After that, only fragments.
Two lives stitched together poorly. Memories that didn’t fit. A name that wasn’t his — but now belonged to him.
“Kaelan Arverth…” he murmured. “I don’t know who you were. But now I am.”
He paused.
There was an unsent message. A conversation postponed. Someone waiting for a reply that never came.
Doesn’t matter. Not anymore.
He cut it there. That was his way.
What did matter was what he knew about this world.
High School DxD. The anime. The light novel. A world where devils, fallen angels, and angels fought in secret while humans remained unaware. A world where Kuoh was devil territory.

And he did not exist in it.
Not as protagonist. Not as antagonist. Not even as background extra.
A nobody. A civilian. A future corpse.
He sat on the edge of the bed in a house that wasn’t his and considered what that meant with the calm of someone who preferred inventories to panic. In a world where people died from spears of light and erased memories, irrelevance was not safety.
It was a delayed sentence.
Protocol: don’t speak to anyone important. Don’t approach. Don’t interfere. Don’t change anything.
Simple. Executable.
But the moment he stepped onto Japanese soil, something inside him reacted.
His chest tightened.
Not pain. Not magic. Emotion.
A foreign pulse resonated beneath his sternum, like a heartbeat that wasn’t his.
He slept little that night. When he did, a persistent hum lingered inside him — constant, wrong — like something trying to synchronize to a rhythm that existed only for itself.
Morning came by inertia.
He put on the Kuoh Academy uniform and looked into the mirror. Dark brown hair, nearly black, framing a face he didn’t recognize.
“Perfect,” he muttered. “Tall, European, long hair. Ideal for blending in.”
He looked like a protagonist designed by committee.
Exactly what he didn’t need.
The walk to school was quiet. Blue sky. Soft breeze. The kind of morning that, in a normal story, would mean everything was fine.
Halfway there, it hit.
A wave of emotion crashed into his senses. Joy. Stress. Desire. Jealousy. Exhaustion. None of it his, yet all of it passing through him as if there were no walls. Every passerby left a trace. Every glance triggered an echo in his chest.
He paused briefly near a woman sitting on a bench — and before he could stop it, he felt her financial anxiety, her love for her daughter, a silent resentment she had never spoken aloud.
The woman looked up. Surprise. Suspicion.
Kaelan walked away.
He wasn’t reading thoughts.
He was absorbing emotional signatures.
And that was a problem he hadn’t accounted for.
The KUOH ACADEMY sign appeared between the trees.
Don’t look at anyone. Don’t approach. Don’t exist more than necessary.
Too late.
The moment he crossed the gate, something warm and immense brushed his senses — like standing beside a dormant inferno.
Rias Gremory.
He didn’t need to see her to know. High-class devil. King. One of the most powerful young figures in her faction.
He kept walking.
But she wasn’t the first to notice.
Cold pressure climbed his spine. Precise. Silent. Predatory.
Koneko Tōjō.
She stopped beside him — not blocking his path. Just existing, like a drawn blade that hadn’t yet decided to cut.
“…Strange,” she said.
It wasn’t the word that hit him.
It was what followed.
Something slipped out of him — an emotional echo, involuntary, uncontrolled. And in the fraction of a second it lasted, Koneko’s emotions flooded his system:
Cold vigilance. Distrust. A buried fear. Loneliness sharpened by years of pain.
Too much.
He stepped back. Not dramatic. Just enough to avoid falling.
Koneko narrowed her eyes — an ordinary gesture carrying lethal weight — and continued walking.
But before disappearing into the crowd, she spoke again:
“…Dangerous.”
