Part 2 Monetary Monster Harem (TF/TG)

The Phantom Thieves ran through the golden corridors of Kaneshiro’s Palace, their footsteps echoing over polished marble floors.

Behind them, the ever-present voice of Kaneshiro blasted through the intercom, taunting them.

“Running again, are you? Poor little thieves, down to five! You’re really bad at keeping your team together. Hah!”
“How’s my lovely Rika doing? Still thinking of me, I bet. Such a good girl.”

Ann clenched her fists. “Ugh, I swear at some point I’m gonna rip those stupid speakers out of the walls.”

Yusuke’s face was calm, but his voice was tense. “He’s playing with us. The longer we stay, the more power he gains.”

Joker motioned toward a door up ahead. “Safe room. In there.”

The team ducked inside, the heavy door sealing behind them with a hiss.

Everyone was breathing hard. The tension was thick in the air.

Morgana paced the floor, ears twitching. “This is bad. This is really bad.”

Ann slumped into one of the seats. “We lost Ryuji…”

Makoto looked down at the table. “No. We didn’t lose him. Not yet.”

Morgana turned sharply. “Right. We can’t give up on him. Once we steal the treasure, the palace disappears, remember? So maybe everything Kaneshiro did to him goes with it.”

Joker gave a thoughtful nod.

Yusuke tilted his head. “It’s a possibility. Palaces are tied to cognition. If the illusion breaks, then so should the spell on Ryuji.”

Ann leaned forward. “Then we just need to find the Treasure. Fast.”

Makoto stood up, decisive. “Let’s go back to the laser maze. That path still looked promising.”

Ann nodded. “I was thinking the same. I mean… Why even have a door like that if there’s nothing behind it?”

Morgana hopped onto the table. “We just have to try the same thing again! I mean, we got further last time, didn’t we?”

Makoto glanced at Joker. “ You and I will take the right path.”

Morgana looked at the others. “I’ll go with Ann and Yusuke. We’ll sweep the left.”

Joker looked around at the team, giving a confident nod.

Ann cracked her knuckles. “Alright. Let’s do this.”

Yusuke adjusted his mask. “We must move swiftly, before Kaneshiro tightens his grip even further.”

Makoto looked back at the map on the wall. “Stay in touch, and don’t take any unnecessary risks.”

Morgana smirked. “We’ll be careful. Promise.”

Joker opened the door. “Move out.”

The Phantom Thieves split up once again… Shaken, desperate, but determined. They weren’t just trying to steal Kaneshiro’s treasure anymore. They were trying to save their friend.

The safe room door creaked open.

Morgana stepped out first, scanning the hallway. “Looks clear. Let’s move—”

FWIP!

A gold-tinted tail shot out from the shadows and snatched Morgana by the waist, yanking him into the air.

“Wha—HEY!”

Before he could react, he was slammed face-first into a massive pair of soft, bouncing breasts.

He froze, face squished into velvet cleavage.

Ann’s eyes widened. “M-Mona?!”

Morgana blinked, dazed. “Wait… boobs?”

His legs dangled helplessly. His arms flailed once before drooping.

“Okay, not… not the worst trap,” he mumbled, still muffled.

CLACK!

Two elite guards stepped out behind Rika, each holding a sleek, black briefcase. Without a word, they snapped them open above Morgana’s head.

WHOOOOOSH!

A tidal wave of money exploded outwards. Thousands of yen notes, glittering with golden ink and Kaneshiro’s smirking face.

The money rained down onto Morgana’s small feline body, sticking to him, melting, absorbing straight into his fur and skin.

Shhhhppp~ shhhhrrrp~

He gasped as his body started to stretch, paws becoming hands, his legs lengthening, fur turning smooth and pale. His body grew taller by the second, reshaping as curves pushed out along his figure. She shot up so fast, growing so tall that under ten seconds, she was nearly Rika’s size.

“Wh-what’s… h-happening—!?” Morgana gasped, voice already changing, higher, lighter, feminine.

His hips widened. His chest began to swell. Two soft mounds pushed outward under his clothes.

Ann shouted, “Let him go, Rika!”

But Rika just laughed, tightening her grip.

“Let her go, you mean,” Rika corrected, her voice dripping with satisfaction.

Morgana’s new fingers trembled, reaching up to touch her now much longer hair. Her eyes darted down, staring in disbelief at her now very human, very feminine body. She was so deep in shock, she didn’t even notice she was still buried in someone else’s cleavage. All she could focus on… were her own.

She stammered, “I… I have boobs!? W-Why do I have boobs?! Why am I—why am I human?!”

“Almost human~” Rika giggled, brushing one of her hands through Morgana's hair. Thats when she noticed. There was one thing that hadn’t changed and that was the two cat ears, still twitching on top of her head.

Yusuke drew his sword. “Release her. Now.”

Rika smiled. “You want to know how I found you?”

She leaned her head down next to Morgana’s, holding her like a doll.

“Shadows can’t see safe rooms. They can’t enter them, either. But me?” She smirked. “I remembered this one. From before I was reborn.”

Ann narrowed her eyes. “You remembered?”

Rika nodded. “I knew you'd run back here. I couldn’t see it, but I knew. So I waited… and you opened the door right into my hands.”

Morgana whimpered, still held tight against her.

“Not fair…” she muttered weakly. “This is so not fair…”

Yusuke tightened his grip on his sword, stepping forward with narrowed eyes.

“She’s stalling us,” he said flatly. “More guards are coming.”

Two more elite guards appeared at the end of the hallway, each one carrying another sleek black briefcase in hand.

Rika looked over her shoulder and grinned.

“Damn right I am.”

She turned to present Morgana, holding her up proudly in both arms like some kind of trophy.

“Give her another load and make her one of us!”

The guards approached, briefcases lifting—

SHWING!

Yusuke’s blade flashed. A single, precise slash tore through both cases before they could open fully.

CRACK! The briefcases split clean in half, and the money inside erupted into the air, fluttering around them like golden snow.

Yusuke stepped back. The cash fell all around him… but not a single note touched him.

Instead, the bills spun in midair, fluttering everywhere. Most of it hit the ground and vanished, harmless. But some notes twisted in the air… like they were being pulled magnetically…

Straight to Morgana.

Several notes flew right to her chest, sticking there with a soft glow before melting into her skin.

Morgana groaned faintly in Rika’s grip.

Shhhhppp~

Her chest pushed out just a little more. And a little more. It wasn't stopping.

Ann’s eyes narrowed. “That’s enough.”

With a crack of her whip, she struck Rika clean across both hands.

“OW—!” Rika snarled, stumbling back as her grip loosened.

Before she could recover, Ann flicked the whip again, this time wrapping it around Morgana’s waist.

“Hang on, Mona!”

With one strong pull, she yanked Morgana free from Rika’s arms and dragged her across the marble floor and into her arms.

Morgana blinked hard, eyes wide and dazed. “Wh-wha…?”

Ann stared at her. “You okay?”

Morgana rubbed her head. “I… I think so. I-I remember everything, but-”

She looked down and immediately gasped.

“WHY ARE THEY STILL GROWING!?”

Ann’s eyes also drifted downward. “Oh wow. Yeah, that’s… those are definitely some prime goods. Holy crap!”

Yusuke stepped beside them, sword still drawn. “We have no time for ogling. We need to go. Now.”

“Right,” Ann nodded, grabbing Morgana’s arm.

They bolted down the hallway, Morgana stumbling a bit as she adjusted to her new height and new body, cat ears twitching wildly.

Behind them, Rika hissed and clenched her fists.

“Tch—she slipped right out of my hands!”

She pointed at the guards furiously.

“Go! Get them! Bring her back!”

The guards broke into a run, chasing after the fleeing trio as the golden bills continued to swirl in the air around them.

At the same time Joker and Makoto were still inside of the safe room, watching all that from the shadows. That's when Makoto turned towards their leader. All eyes are on them,” Makoto whispered. “This might be our best chance to move. We need to hurry.”

Joker stoically nodded.

Ann, Yusuke, and Morgana ran down the long, gold-plated hallway, boots clacking on the polished floor.

Golden yen notes still floated lazily from the ceiling, spinning through the air like glittering snow.

Morgana, who was now fully human-girl-shaped, curvy and flustered, with cat ears twitching, kept glancing up at the falling money.

She reached for a note mid-run. “Just one more, I mean, it’s harmless, right?”

Ann yanked her by the sleeve. “Mona! Focus!”

Morgana huffed, still running. “Right, right! Just… it’s everywhere! It’s hard not to look at it!”

Yusuke stayed ahead of them, cutting a clean path with precise footwork. “We must move faster. Those guards will be close behind.”

The hallway bent into a tight maze of security lasers, flashing and humming with energy.

Ann grinned. “Perfect. Let’s lose them in here!”

The three darted into the laser maze, ducking and weaving through the thin beams with practiced grace. Morgana stumbled once or twice, distracted again by fluttering cash, but Ann kept pulling her along.

Bzzzt! Zhhhhrm!

Overhead, Kaneshiro’s voice cracked through the speakers.

“Seriously? You brats are still moving? Grrgh—fine! GUARDS, GET IN THERE!”

“...but sir. This laser maze isnt meant to be…”

“Then turn off the lasers! I want them caught!”

Suddenly, the humming stopped.

TCHUNK. The lasers powered down.

“That is…” Yusuke blinked. “Most unexpected.”

—

Meanwhile Makoto and Joker crouched near the reinforced vault door at the end of the right corridor.

“What the…?” She glanced up. “The lasers are down.”

Joker nodded. No hesitation.

He stepped forward, placing his hand on the console beside the massive door.

BEEP. BEEP. BEEP.
 ACCESS GRANTED.
 THUD-THUD-CLANK—

The heavy door slid open, revealing a long hallway drenched in golden light. Makoto instantly informed the other thieves via their intercom. “The door is open. We are going in!” 

Makoto then turned to Joker. “Let’s move.”

Joker nodded with a smile.

—

Ann, Yusuke, and Morgana reached the same door shortly after, just in time to see Joker and Makoto disappearing down the hall that was previously blocked by the reinforced door.

“We’re right behind you!” Ann shouted, pulling Morgana by the wrist.

The group sprinted through the golden corridor and entered the next room-

And then they froze.

Before them was a massive vault chamber, the size of a gymnasium. The walls were made of glass, and behind that glass-

Mountains of cash.
Piles and piles and piles of yen.

Billions, trillions, It was impossible to count.

The light from the room shimmered off the notes like gold foil.

Morgana pressed her hands and face to the glass, eyes wide with awe.

“It’s the treasure. This has to be the treasure!”

She turned to the others, heart pounding.

“We need to take it! All of it! Every last note—!”

THOOM.

A heavy thud echoed behind them.

THOOM.

And then-

“If you like that bit of pocket change so much, then take it-”

The voice was smooth, smug, and unmistakable.

Rika.

Before anyone could turn, her massive golden tail slammed into Morgana, sweeping her off her feet and knocking her back. 

“As payment for loyalty!”

“Wha—!?”

CRASH!

Morgana hit the glass, which shattered instantly, sending her plummeting into the enormous, public pool–sized pit of money.

Yusuke shouted, “MORGANA!”

Ann ran to the edge. “Mona!!”

The money rippled and shifted like a liquid sea. Morgana was gone beneath it, who knew how deep.

Rika stood proudly at the room's entrance, arms crossed, watching them like prey. “She wanted the treasure, didn’t she? Let her drown in it. Let her drown and be reborn as a guardian of wealth!”

—

Morgana sank deep into the pit of money.

The cash wrapped around her like water, soft and endless, pulling her under. She couldn’t breathe… but she didn’t need to. She could feel it.

The money wasn’t just covering her.

It was melting into her.

Shhhrrrp~ shhhhpppp~

Thousands of bills, each with Kaneshiro’s face, pressed against her skin, then vanished beneath it. Her body soaked it all in like a sponge.

“M-more… I… I need more…”

Morgana’s voice was soft, almost dreamy.

She reached out, grabbing fistfuls of yen notes, stuffing them into her own chest, her arms, her legs. Every time her fingers touched them, they disappeared into her, and something inside her shifted.

She felt her torso swell, her chest puffing out further. Her curves deepened. Her skin grew smoother, but it wasn’t just that…

Her arms tingled, the sensation crawling down her limbs.

She lifted one hand and gasped.

“Wha…?”

With all the greenery around her she couldn't see it, only feel it. Her fingers were stretching longer, the tips turning pointed. Claws. Sharp and gold. Her arms were hardening, tiny golden scales running up her skin in patches.

“M-my arms… my hands…!”

She reached for her legs… but… something was wrong.

“W-where…?”

Her upper body felt lighter, detached, like her legs weren’t even hers anymore. She tried to kick—nothing. She couldn’t feel her toes.

Because she didn’t have toes anymore.

CRACK.

TWIST.

Her lower half was moving away at breakneck speed, and something between her stomach and her hips was growing, stretching, deforming… becoming long, thick, and serpentine. She couldn’t see it from where she was floating in the money, but she felt it.

Her feet cracked apart, bones shifting, toes stretching out into huge, scaled dragon talons.

Massive, heavy, unnatural.

But the thought didn’t bother her. Not really, it felt right, because the more monstrous she became, the more money she could hold.

She tried to look behind her… around her… at anything… but all she saw was green. Green power that made her body bigger and better.

“It’s… huge…” she whispered.

“I’m… huge…”

And still, the money came.

More, more, more.

Her mind spun. Greed wrapped around her like the money did. Her thoughts were warping.

Kaneshiro has money…
Money is power…
Power must be obeyed…

She moaned softly as another wave of bills poured into her chest, her stomach, her growing serpent tail.

“Kaneshiro… is powerful… Kaneshiro… deserves loyalty…”

Then… she felt it.

Something… sprouting.

Down below, where her monstrous tail coiled beneath her—

A second version of her began to grow.

A new torso, rising from the same lower body. A copy of herself, complete with her figure, her hair, her golden claws-

Her eyes widened. “Wha… there’s… another me?” 

The second Morgana reached forward, scooping up even more money with greedy hands.

It didn’t speak. It just obeyed the hunger. The endless hunger for more cash.

Just as that second torso had grown to full heights, immediately, she felt it again.

Another one was coming…

A third torso started to grow out from her lower half.

It pushed through smooth and fast, the same body, the same curves, the same long black hair and twitching cat ears.

Morgana trembled. “It’s… happening again…! I am so much…”

Her voice came out shakier, but she didn’t resist.

“So many…”

She felt her lower half widen, thickening like a massive lizard’s trunk. No… like something worse. Something ancient.

A fourth torso.

It sprouted on the other side. She could feel it lock into her spine, connected, moving as part of her.

A fifth. A sixth. A seventh.

Each one perfectly matched the first, all copies of her. Beautiful, monstrous, obedient. Each one reaching, grabbing, feeding more and more money into the shared body.

Her mind buzzed with it.

Her thoughts should have been panicked… but instead, they felt calm, loyal.

“This is… right,” she murmured, “I’m built to serve someone like him…”

“Money is power. Kaneshiro has money.”

“He deserves everything.”

Her body shifted again as something massive unfurled from her back.

WHOOSH.

Wings.

Two huge, golden wings ripped free from her back, spreading wide with a deafening flap, causing ripples through the endless sea of cash. The skin of her lower body was now fully covered in beautiful black and gold scales, shimmering like obsidian under light. It looked like she was a dragon, who had many many dragon-like lamias on the top instead of a head.

On each of her human torsos, her arms ended in claws, sleek and sharp. Each of the torsos all resembled snake-like tails, all connected to her massive dragon body. Her Dragon lower half now had four deadly talons, crashing through the pile of cash like steel blades, but never slicing anything. Cash is something to be valued and never to be destroyed after all.

“I’m… I’m becoming something more.”

“Something worthy.”

The mountain of cash began to shrink, absorbed into her endlessly expanding body.

As the last of the money vanished into her, the glow dimmed-

Revealing the true form of what Morgana had become.

A ten-meter tall dragon-hydra, its body humongous and terrifying. The lower half was that of a quadrupedal dragon, black-scaled, thickly muscled, with massive wings and razor talons.

From that monstrous body rose eight upper halves, each of them a busty, dragon-girl version of Morgana. Each one beautiful, obedient… and smiling.

Their eyes all glowed gold. All of their claws had the imprint of dollar signs on them.

Their voices spoke together, perfectly in sync:

“We are Morgana. We are Kaneshiro's Devastator.”
“We serve Kaneshiro.”
“He is power. He is wealth. He is everything.”

The eight torsos bowed together.

“He is our boss, and he must be obeyed.”

“Dear me…” Yusuke looked at the hydra dragon Morgana in shock. Even Rika seemed surprised.

“For real…?” She let out, looking at the eight headed, ten meter busty hydra dragon girl. “I mean I knew that throwing her into a pool of cash was going to get her to the right side, but god damn…”

“This is getting really freaking bad!” Ann declared, pulling on Yusuke's arms while Rika was distracted. “We need to get out of here! We lost Mona! Help!!!”

—

The phantom thieves have been stuck in Kaneshiro's Bank for quite a while now. So long that it seemingly started to affect them. After loosing Ryuji to greed, Mona was next to follow. The phantom thieves better step up their game or this will be game over for the rapidly monster girling crew.
