**Roy's POV**
Roy blinked. Or at least, he *thought* he blinked. The world around him was a smear of gray pixels, like his shitty laptop had decided to render reality in 480p. One second, he'd been grinding through another all-nighter in his cramped apartment—energy drinks, half-eaten pizza, and the glow of his monitor as he doom-scrolled Reddit for "isekai done right" threads. The next? Blackout. No dramatic truck-kun, no mysterious old man with a bean. Just... *poof*.
"Welcome, Host Roy," a voice boomed in his skull, synthetic and chipper, like Siri after chugging Red Bull. "System initialization complete. You have been transported to the High School DxD universe. Pre-Issei Hyoudou era: approximately 10 years prior. Your new body: optimized for chaos. Stats loading..."
Roy's vision snapped into focus. He was standing in a misty forest clearing, the air thick with the scent of pine and something metallic—blood? No, wait, cherry blossoms? The trees loomed like extras from a Studio Ghibli flick, but edgier, with faint red glows flickering in the underbrush. He glanced down at himself: black jeans, a faded Naruto hoodie (the one with the orange fox on the back), scuffed sneakers, and... holy shit, muscles. *Actual* muscles. He flexed an arm—veins popped like he'd been hitting the gym for years, not avoiding it like the plague.
"What the actual fuck?" Roy muttered, patting himself down. Wallet? Gone. Phone? Nada. But in his pocket, a sleek black card hummed against his thigh, warm like it was alive. He pulled it out: matte obsidian, etched with glowing blue script. *System Card: Roy's Wild Ride.*
The voice pinged again. "Host confirmed. Age: 20. Alignment: Chaotic Neutral (upgradable via kills, quests, or sheer dumb luck). Perk unlocked: Anime Arsenal. Pull from any series in the database for abilities, items, or summons. Randomization factor: 100%. Warning: No refunds on bad rolls."
Roy's brain short-circuited. "DxD? Like *High School DxD*? The one with the boobs and the devils and the—wait, pre-Issei? So, like, Sirzechs is still a badass, but no Oppai Dragon memes yet?" He laughed, a sharp bark that echoed weirdly. This had to be a dream. Or a stroke. But the ground felt solid under his feet, and a distant howl—demonic, guttural—prickled his skin.
"First quest: Survive the stray exorcist ambush. Reward: Random ability draw. Failure: Permadeath. Have a nice day!"
Stray exorcist? Roy spun, heart slamming. Through the trees, shadows slithered—figures in tattered white robes, crosses glinting like switchblades. Three of them, eyes burning with holy zeal. One snarled, "Fallen's taint! Purge the sinner!"
Roy bolted. Branches whipped his face as he crashed through the undergrowth, lungs burning. *Not a dream,* he thought, *definitely not.* The System card vibrated, projecting a holographic menu in his vision: [Draw Now? Y/N]. "Fuck yes!" he gasped, slamming mental yes.
*Roulette spin initiated. Drawing from Tier 1-5 databases...*
The world slowed. A slot-machine whirl of icons flashed: a spiky-haired Saiyan, a notebook with a Shinigami grin, a rubbery pirate arm, a blue-haired mecha pilot mid-scream. It landed on... *JoJo's Bizarre Adventure*. Sub-roll: *Tier 1 Classic*.
"Congratulations! Unlocked: Stand Manifestation (Random). Your Stand: [Star Platinum: The World]. Wait, no—glitch! Hybrid roll: [Crazy Diamond: The World]. Ability: High-speed punches at 300+ BPM, with time-stop bursts (10 seconds max, 5-min cooldown). Visual: Pink-skinned muscle hunk with a timepiece for a head. Summon phrase: 'Yare yare daze... but make it quick.'"
Roy skidded to a halt behind a boulder, chest heaving. The exorcists were closing in, light spears crackling in their hands. "Stand? Like Jotaro's? Shit, yes!" He clenched his fist, whispering the phrase. The air *ripped*—a surge of raw power, and there it was: a towering, ethereal figure, all rippling abs and a clock-face mask ticking ominously. It flexed, veins bulging like overinflated tires.
The lead exorcist lunged, spear aimed for Roy's throat. "For the Church—"
*ORA ORA ORA ORA!* The Stand exploded forward, fists a blur of pink fury. Time stuttered—*ZA WARUDO*—and the world froze in grayscale. Ten seconds of frozen hell: Roy's Stand pummeled the exorcist into paste, spears shattering like glass. Snap back to color, and the other two were mid-air, faces twisting in confusion.
*ORA ORA ORA!* More punches, bones cracking like fireworks. One exorcist managed a desperate swing—his cross grazed Roy's arm, searing like acid—but the Stand caught his wrist, *CRACK*, and time-stopped again. Roy, panting, grabbed a fallen spear and jammed it through the guy's chest. The third bolted, but a final barrage turned him into a red smear on the trees.
Quest complete. The bodies dissolved into holy ash, leaving behind twinkling motes that the System slurped up like XP candy. "Level up! +5 Strength, +3 Agility. New perk: Item Summon (one-use per chapter). Draw now?"
Roy slumped against the boulder, blood—*his* blood—dripping from the burn on his arm. It stung like hell, but the pain grounded him. "Yeah... draw." The roulette spun again: *Demon Slayer* icon, *Ufotable glow*. Sub-roll: *Tier 1 Breakout*. "Unlocked: Nichirin Blade (Random Variant). Yours: Water Breathing Style— but wait, hybrid glitch! *Thunderclap and Flash: Crimson Edition*. Item: Red-hilted katana that ignites on slashes, +20% speed boost during storms. Bonus: Can summon Tanjiro Kamado (holographic ally, 5-min duration, once per day)."
The blade materialized in his hand—light as air, edge humming with latent lightning. Roy swung experimentally; a arc of red thunder cracked the air, singeing leaves. "Holy shit. This is... OP as fuck." But the System's voice glitched, static-laced: "Warning: Draws are *extremely* random. Next could be a spoon from *Baccano!* or a cursed doll from *Erased*. Use wisely. Secondary quest: Head to Kuoh Town. Infiltrate as a transfer student. Objective: Seduce or ally with a devil peerage. Reward: Second ability slot."
Kuoh Town. Roy knew it from the manga scans he'd binged last month—sleepy suburb hiding a den of devils, angels, and fallen drama. Pre-Issei meant Rias Gremory was probably still a high schooler, all crimson hair and barely-contained power. Sirzechs ruling the underworld, Azazel scheming in the shadows. No sacred gear nonsense yet, just pure fa
ction wars.
But Roy? He wasn't some wide-eyed protagonist. Back home, he'd been a burnout—dead-end job, ex who ghosted him, a stack of regrets taller than his anime backlog. Here? With a JoJo ghost-puncher and a demon-slaying sword? He could be *anything*. Deadbeat dad? Nah, too much paperwork. Dio-level villain? Tempting, but he'd probably trip over his own ego. Killing spree? The exorcists' blood still flecked his hoodie; it felt... *right*. Addictive, even.
"Yare yare," Roy muttered, sheathing the blade. The Stand faded with a nod, clock-face ticking approval. "Let's fuck this world up."
He stepped onto the dirt path leading toward distant city lights, the System card pulsing like a heartbeat. Random abilities, summonable waifus (or husbandos), items that could nuke a city block. And lemons? Oh, he'd earn those. Slow-burn, alternating stares across classrooms, until Chapter 15 hit like a freight train. Rias? Akeno? Some OC devil with trust issues? The System didn't care—as long as it was smutty, chaotic, and canon-adjacent.
Kuoh awaited. And Roy? He was just getting *started*.

**Rias Gremory's POV (Teaser for Chapter 1)**
In the opulent halls of the Gremory estate, Rias Lucifer—*Gremory*, she corrected herself with a wry smile—paced the crimson-carpeted study. At 15, she was already a force: heiress to one of the 72 Pillars, crimson locks cascading like spilled wine, blue eyes sharp as devil's bargains. But tonight, the air hummed wrong. Scouts reported a disturbance in the outskirts—a surge of *foreign* energy, neither holy nor demonic. Like anime static bleeding into reality.
"Grayfia," she called to her maid, who stood sentinel by the door, silver hair impeccable. "What do we know?"
The Queen's expression remained stone. "A lone human, Lady Rias. Slaughtered a stray exorcist pack single-handed. Energy signature: anomalous. As if... pulled from another narrative."
Rias's lips curved. Anomalous. She liked that. In a world of predictable pawns and fallen betrayals, anomaly meant *opportunity*. "Bring him to Kuoh Academy. Discreetly. I want eyes on him."
Grayfia bowed. "As you wish. But caution: his aura reeks of unpredictability. Like a Stand user in a breathing world."
Rias laughed softly, settling into her father's old armchair. Unpredictability? She'd tamed worse. And if this stranger proved useful—or entertaining—she'd peerage him herself. The game was changing. And she intended to win.
