DxD : Nah I'd Groom

Its connected to This story specifically Leo's past life aka one of his close people getting reincarnated by the Same Multiversal Charter but unlike Leo they got forked over.

----

After a long while of relentless thrashing, the so-called Strongest Dragon lay battered and bloodied on the ground.

Ddraig's crimson scales were cracked and dented, his once-mighty form barely recognizable beneath the bruises and scorch marks.

Meanwhile, Tia sat comfortably on a conjured chair, legs crossed and radiating pure, childlike satisfaction.

Her aura, which had been a storm of chaotic might moments ago, now was like a soft breeze, light and playful.

She looked like a kid who had just spent the whole day at an amusement park.

Leo strolled over to Ddraig, giving Tia a side-eye as she started flexing her fingers again, a dangerous glint in her eyes.

Seemingly getting ready for Round Two.

"Okay," Leo said, snapping his fingers and restoring Ddraig's natural healing factor. "I think he's had enough."

Tia sighed in disappointment, her cheerful glow dimming. "Fine," she muttered, slumping a little in her chair.

Ddraig groaned, stirring slightly as his wounds slowly began to mend.

Blinking through swollen eyes, he turned his head... only to see Leo standing over him, holding one of the glowing green gems that had been embedded in his body — a literal piece of him.

"So... like," Leo began, inspecting the gem with curiosity, "what's the sensation in these things? Do they have feeling? Or are they more like dead cells — you know, like hair or claws?"

Ddraig's groggy mind cleared instantly, and rage boiled within him.

"You—!" he snarled, barely managing to raise his head.

"Uh-uh," Leo wagged his finger. "Before you try anything, remember... I can turn that healing factor off again."

Ddraig's jaw clenched. He wasn't stupid. If Leo could casually switch his regeneration on and off like a light switch, who knew what other terrifying tricks he had up his sleeve?

"Smart dragon," Leo said, smirking as he casually tossed the gem back to Ddraig like a coin.

"So... while you were having a friendly reunion with Tia," Leo started casually, his grin widening as Ddraig's eyes narrowed with a low growl rumbling in his throat. "I was thinking about something else..."

Ddraig's growl deepened. "What could you possibly have been thinking about?"

"Well," Leo shrugged, "to be fair, I already have enough PR material as it is — y'know, big scary Satan and all that — and considering I'll be attacking Heaven before my debut in the Underworld..."

He paused, before smirking. "I've still got a proposal for you."

Ddraig snorted, his gaze sharpening. "What proposal?"

Leo extended his hand, finger pointed directly at the battered Red Dragon. "You become my familiar."

Ddraig blinked. "...What?"

"You heard me." Leo grinned wider, looking far too pleased with himself. "My familiar."

"How the hell am I supposed to be your familiar?" Ddraig snapped, his voice rising. "I don't even have a body!"

"Eh, don't worry about that," Leo waved dismissively. "I can easily fix that. Just say yes or no."

Ddraig stared at him like he'd just suggested tying Excalibur to a stick and calling it a mop. "Easily fix that? How—"

"Yes or no," Leo interrupted, wagging his finger. "Don't overthink it."

On the side, Tia had been lazily pretending to ignore the conversation, but now her interest spiked.

She leaned back in her conjured chair, one leg crossed over the other, head resting on her fist.

Her smug expression said I'm just here for the show, but her eyes gleamed with curiosity.

"Are you serious?" Ddraig asked again, incredulous.

"As serious as I can be.," Leo shot back.

Tia barely suppressed a snort. Ddraig's face twisted between frustration and disbelief, but Leo's expectant grin remained steady.

Before answering, Ddraig's gaze hardened. "What will happen to my host?"

Leo's grin faltered slightly. "Do you actually care?" he asked, his eyes narrowing.

"Yes." Ddraig's tone was firm. "I haven't met them, but I'm sure someone powerful already has their eyes on them. Making them lose their power is just setting them up for death..."

Leo tapped his chin, looking thoughtful. "Well... I don't particularly think that'll be a problem, but okay." He shrugged. "I'll give them something to work with."

He didn't tell Ddraig that he was going to do something similar nonetheless if he asked or not.

Ddraig relaxed slightly, but then—

"One more thing," Ddraig said, his voice low but resolute.

"What?" Leo asked, his patience starting to wear thin. He was slightly reconsidering his choice now.

"You gotta free White too."

Leo blinked, then laughed dryly. "Oh, that?" He waved his hand like it was nothing. "Yeah, sure. I'll free him."

"Just like that?" Ddraig asked suspiciously.

"Just like that," Leo said, flashing a grin.

"So, uh... how exactly do we do this?" Ddraig asked, shifting uncomfortably.

Leo extended his fist, grinning like a kid about to pull off a prank. "With a fist bump."

Ddraig stared at the offered fist, then back at Leo. "You're joking..."

"Nope. Dead serious."

For a second, Ddraig looked like he was reconsidering his life choices. Then, with a grumble that sounded suspiciously like "This is so stupid..." he lifted his giant claw, somehow managing to delicately curl it into something resembling a fist.

Clink.

The moment they bumped fists, a wave of power rippled through the air like someone just turned on a subwoofer at max volume.

Ddraig's scales shimmered, glowing faintly as magic flowed between them.

"...That's it?" Ddraig blinked. "That's how this works?"

"Yeah," Leo said, brushing off his hands. "Bet you were expecting some ancient chant or blood ritual, huh?"

"Frankly, yes!" Ddraig huffed. "A fist bump? That's just insulting to my dignity as a—"

"My familiar," Leo cut in with a smirk. "You're my familiar now."

Ddraig groaned loudly. "I hate this already..."

Ddraig was unable to finish as the contract finally worked its way to the final aspect of the contract.

The very instant a wave of energy shot out from Leo like a bass drop at a bad rave party.

The air cracked, and the space around them began to twist and splinter like someone had just punched a hole in reality.

Ddraig's scales started to crack, glowing with golden light seeping out from beneath.

"Uh... I'm gonna assume this is because of the contract?" Ddraig asked, his voice a mix of confusion and panic.

Leo tried — really tried — to pull off his best clueless face but his catlike grin was hard to wipe off.

"Well, technically, familiar contracts work by...uh... the stronger party influencing the weaker one... so... yeah?"

Then Leo's face shifted to sudden panic with Ddraig staring at him with a deadpan. "Oh... crap…."

Its over, he knows.

"OH CRAP?!" Ddraig's voice shot up an octave. "THIS WAS A TRAP! I KNEW IT! YOU- YOU-'

Before Ddraig could finish his monologue, a cocoon of swirling magic engulfed him. His furious cursing turned into muffled grumbles as the barrier sealed tightly around him like a magical burrito.

"Be grateful," Leo muttered, massaging his temples. "You'll be stronger when you're done cooking." With a sigh, he flicked his hand, shoving the cocoon into his personal world like someone chucking leftovers into the fridge.

He turned back — and there was Tia, arms crossed, face set in the most judgmental stare Leo had seen since his mother caught him watching anime at 3 a.m. on a school night.

"You just wanted Ddraig as your pet," she deadpanned.

Leo casually raised his hand, giving her a grin so smug it belonged on a billboard. "You got me."

"Well, you can leave now," Leo said, waving his hand dismissively at Tia.

"Why?" Tia asked, crossing her arms.

Leo shrugged. "I'm gonna head out in a few seconds too, but first I need to... tweak some things about this guy.".

"I say you kill him," Tia said, completely serious.

Leo blinked. "What?"

"Just kill him," she repeated, her face calm, like she was suggesting what toppings to get on pizza.

"Well, no," Leo deadpanned. "I don't think he deserves death. It's not like he's the sole person to blame for his situation."

"Pleeease~" Tia suddenly leaned in, her hands pressed together, eyes wide and pleading like a kid begging their parents for candy.

"No." Leo's face hardened. "And that's final."

"Come onnnn," Tia pushed, giving him an exaggerated pout.

"No!" Leo said monotonously , turning away with finality. "I'll tweak his personality a little, but that's it."

Tia huffed dramatically, flopping down into her conjured chair like a sulking teenager. "Fine..." she muttered under her breath. "But if he pisses me off ever in the future, I'm calling dibs on his funeral."

Leo paused, pinching the bridge of his nose. "Tia..."

"I said dibs!"

Leo sighed deeply once Tia was gone.

He turned his gaze back to the crumbling Sacred Gear space — the crumbling remains of the Boosted Gear floating like shards of glass suspended in the air.

With a flick of his wrist, Leo drew out all the remnants of the previous users — a collection of distorted souls lingering like shadows clinging to the walls.

Their vague outlines flickered, jittery and unstable, as if they knew something was horribly wrong.

They were on edge — and understandably so.

After all, Leo had just severed Ddraig from the Boosted Gear.

"Relax," Leo said, his tone flat yet oddly casual. "I'm not here to wipe you out or anything."

The remnants stared at him silently.

No trust. Just fear.

"Well... actually," Leo corrected himself with a smirk, "I am going to wipe you out — but in a creative way."

He raised his hand, golden energy swirling at his fingertips. "I'm going to make a new Sacred Gear out of you."

The remnants shivered violently — one of them even let out a faint whisper, something between a plea and a curse.

"Yeah, yeah, you can haunt me later." Leo rolled his shoulders and began weaving the energy, pulling their fragmented souls together like string through a loom.

"Don't worry," he muttered to himself. "I'll make something... beautiful."

Leo merged the remnants together, condensing them into a chaotic, writhing ball of energy.

The swirling mass flickered with distorted faces and faint echoes of desperate cries — the regrets, fears, and failures of countless souls compressed into one miserable blob.

With a wave of his hand, Leo modified the Boosted Gear's structure.

Its original form twisted and reshaped itself, transforming into something new — a Depression Furnace.

The Furnace's core would feed off the negative emotions saturating that blob of consciousness — regrets, loathing, self-hatred — all the festering ugliness collected over generations.

The leftover soul fragments — the "soul organs," so to speak — were carefully tucked into small chambers within the Furnace, serving as mana generators to keep the new Gear stable.

"That should keep it running," Leo muttered, stepping back to admire his grim creation.

Now came the next step — correcting Issei.

Well... not correcting in a mind-melting, personality-scrambling way — that was too much effort.

Instead, Leo opted for a gentler approach: tweaking Issei's mindset just enough to jolt him awake from his usual perverted daze.

He would wake up today and realise that he needs to change himself and be better.

Leo also left a minor... let's call it a depression bomb in his psyche — the mental equivalent of a mega post-nut clarity that would slap him across the face once he sobered up for a week.

That bomb would be the catalyst to awaken this new Sacred Gear — a painful yet necessary reality check.

Leo paused, sensing something still unfinished.

"Oh yeah..." He glanced at the Skills, instincts, and techniques from previous Boosted Gear users clung to the "Ball of Fuel" like residue — abilities like Flight, Telepathy, and Penetrate.

"Can't waste that."

Leo smirked, snapping his fingers. The lingering energy shot into the Furnace, locking in place like a puzzle piece.

Still, Leo wasn't satisfied. Sure, the Furnace was functional — efficient even — but he had standards.

And this was not upto los pollos standards.

With a thoughtful hum, he extended his hand once more, drawing out other parts of the sacred gear not in use.

Carefully, he sculpted a new chamber — a core embedded within the Gear's structure.

This chamber had a special purpose — it would absorb souls tainted by hatred and negativity, including those of the beings Issei killed or came across.

It wasn't just a disposal unit either; Leo's handiwork ensured this chamber could break down those souls — even to an extent, digest a god.

Any powerful soul caught in its web would gradually have its abilities imprinted onto the wielder.

"Now we're talking," Leo muttered with satisfaction.

So, for the Gear's manifestation, Leo crafted something more intimidating — an armor forged in rage and defiance.

It resembled the twisted, jagged design of Lancelot's Berserker armor.

To complement that power, the Gear would also adapt to Issei's mind — manifesting whatever melee weapon Issei considered the most ideal in a given situation.

Of course, power like this didn't come without a price; it weakened his armour based on how powerful the melee weapon he projects is.

As a fun byproduct, Issei's aura was now poisonous.

Despite his teasing earlier, Leo knew Issei wasn't a bad guy.

The dude literally saved the world — multiple times, no less and he was a genuinely kind guy.

The problem was... well, one glaring trait tended to drown out all his better qualities.

Leo sighed, rubbing the back of his neck.

"Hopefully," he muttered, "this'll help him pull his head out of his ass."

Leo appeared outside Issei's house with a faint shimmer, the air around him rippling before settling down.

Tia was long gone.

No problem. He closed his eyes, focusing for a moment. Instantly, he found her — still sitting at the same park bench from earlier.

Lazy dragon, Leo thought with a smirk.

Before heading off, he glanced back at Issei's room. Something felt unfinished. Clicking his tongue, Leo raised his hand.

"Alright, fine," he muttered.

With a flick of his fingers, he boosted Issei's ability to gain muscle and magic when he trained.

Nothing crazy — just what everyone had as an aptitude which Issei lacked.

Since Issei's body was abysmally talented.

Even with all the upgrades, Issei could never match Leo's level.

Well that's a bit harsh comparison.

But this would make sure the guy could survive if he awakened his Sacred Gear.

Feeling satisfied, Leo turned to leave.

Then — an idea hit him.

A wicked, absolutely evil idea.

His grin widened, a dark chuckle escaping his lips.

Oh, this is genius…

Leo raised his hand again, his fingers glowing faintly as he reached back into Issei's soul.

"New day… new size… hehehe…"

The spell settled in — sneaky and impossible to notice.

The effect well lets just say little issei was now Variable.

Leo wiped a proud tear from his eye.

"I've really outdone myself," he muttered with a smug grin before vanishing into the night.

—

Leo strolled up to Tia, who was quietly watching the sunrise.

Her eyes soft as the golden hues painted the sky.

For a moment, Leo considered not disturbing her — but before he could decide, a glowing screen blinked into existence in front of him.

[The Lonely Mother: My transfer was approved.🤗… I will be there now!]

Leo blinked, then looked at Tia still sitting peacefully.
