Conquering Heroines: Starting From A World Of Zombies

When Ryuji regained consciousness, he found himself not in a familiar place, but in a damp cave. His clothes were completely gone—and worse, he noticed that his lower body was still wet.

Still, surprisingly, all of his belongings remained—except for his tablet, which had been replaced with two gold bricks of the same size.

Ryuji buried his face in his hands, speechless. He never imagined Azula would be that kind of woman.

He'd gone all out on her… only to be outplayed in the end.

With a sigh, he admitted to himself,

"I still lack experience."

Sitting up, he noticed a slip of paper tucked beneath his head. Picking it up, he saw it was a note—left by none other than Azula.

The message was short but full of disturbing implications:

"Guess what I might have done to you while you were unconscious?Did I get your child?

Darling, next time we meet, I'll be bringing along a few girls to help carry your bloodline…But remember, I will always be the first wife.

Thank you for your kindness—and I'm sorry for exploiting it. But I'll never allow anyone to willingly leave me again.

Oh, and before I left a message for Toph, saying that you dumped her because she's short, has smelly feet, and small boobs and butt.

My spies told me she's been planning to kill you.So you better be careful."

He read the note and had only one reaction.

"Yep… she's crazy."

Shaking his head, he stuffed the note into his backpack with a sigh.

The tablet hadn't had his movies or personal files—but it had contained a fully integrated industrial blueprint archive, advanced scientific knowledge, and even outdated Earth technologies that were still considered revolutionary in this world… including satellite tech.

That tablet had been his bargaining chip for something… a little personal. Yes, he had once considered using it to trade for Lux's virginity. But now Azula had taken it.

He had no doubt someone like her would quickly realize how powerful those documents were. And just like that, the future of this world had been drastically altered because of his unintentional mistake.

That said, beside his backpack lay a large stack of scrolls.

Curious, Ryuji inspected them. They were packed with densely written texts—manuals on water bending, healing arts, earth bending, air techniques, and even rarer derivative skills like lava manipulation to escape techniques.

Many bore the same signature at the top: "Avatar".

These were relics written by past Avatars.

"Interesting..."

Clearly, Azula hadn't just stolen something—she had paid handsomely in return. In terms of difficulty, acquiring these scrolls probably cost her more than what she took.

But in terms of value, it wasn't even close.

The bending techniques were powerful, sure—but only worked on naturally gifted individuals. In contrast, the knowledge Azula took could empower a civilization. One working missile design, one application of chemical fertilizer—instant technological supremacy.

Still, considering how bending could impact industrial development, he realized the future was about to shift dramatically.

For a brief moment, he frowned.

Then, spreading his hands, he muttered:

"Whatever. Not my world. Not my problem."

He was just a bystander—a poor, unlucky guy who'd been seduced and maybe even violated by a crazy woman. Whether Azula had actually gotten pregnant with his child, he didn't know. And honestly, he care worry about that after a few months.

Besides, pregnancy isn't that simple, right?

He was pretty bad at aiming anyway—no way he'd land a critical hit like that under such messy circumstances!

But the key detail?

Ryuji checked his energy interface.

It was unchanged—still stuck at 4620.

That meant Azula hadn't done anything while he was unconscious.

If she had, the energy value would have changed.

"Hah. Figures."

He'd gotten over 2,000 energy points in a single night thanks to Azula.

"Okay, enough brooding. Time to leave."

He quickly scribbled two notes—one for Azula, one for Toph—and placed them on a nearby stone.

The note to Azula was short:

"Next time we meet, I'll fuck you until you lose your mind. And don't touch the letter meant for Toph."

The letter for Toph was more sincere:

"Azula drugged and kidnapped me. I didn't leave by choice. Don't overthink it—I'll be back in a few months."

He had no idea whether either note would be found, but he was sure Azula was watching from the shadows. She'd probably stop him from finding her, maybe even actively sabotage him.

She was smart, ruthless, and unrelenting—Ryuji knew he couldn't outplay her in a game of lies and manipulation.

And let's be honest—she had loyal fire benders who still weren't ready for peace. He had no allies, no knowledge of this terrain.

So the best plan was simple: get stronger and come back later to beat her at her own game.

That said, he had to admit—

"Damn… bad girls really are something else."

He smirked at the recorded footage on his device—Azula, eyes unfocused, sobbing, crying out for her parents in a pleasure-induced haze—Ryuji let out a cold laugh.

He copied the file and transferred it to a backup phone. Placing that phone gently on the cave floor, he opened his dimensional interface and selected the cheapest available world—Nico Robin's.

He wasn't going to stick around in this messy realm of tangled emotions, nationalist feuds, and chaotic vengeance.

The whole Azula and Zuko situation? It screamed trouble from every angle.

He'd come back later to see how things had played out.

With that, he activated the transfer. His body began to turn transparent, slowly phasing out of the cave.

Moments after he vanished, Azula's silhouette emerged from the shadows deep within the cave.

She immediately noticed the phone he left behind, picked it up, and opened it—only to be greeted by the haunting footage of herself in a dazed, broken state, crying for her parents mid-climax.

Her expression froze. She shut the phone off with trembling hands and deleted the video without a word.

Then, she turned to the letters Ryuji had left behind and the spot where he'd disappeared, murmuring to herself:

"So he really is a god…? You arrogant bastard… I haven't lost to you!"

Eyes narrowing, she scoffed coldly and turned toward the darkness deeper inside the cave.

Within that darkness, a loyal official, one whom Zuko had recently interacted with, stepped forward. Bowing respectfully, he asked:

"That man… is he your husband?"

"Yes," Azula answered plainly.

Her lips curled into a strange smile as she thought of the contents of Ryuji's tablet: books on imperial strategy, histories of entire civilizations, theories on social systems.

She spoke clearly and deliberately:

"And he is your future king."

She no longer cared much about ruling the world. All she wanted now was to complete the conquest she'd started long ago—to prove Zuko and the Avatar wrong.

The world itself was merely a tool for that purpose.

And as for her partner—only Ryuji would be her husband.

Not even an Avatar deserved that title. Only gods—those who transcended worlds—qualified to stand beside her.

"Alright, let's move. We have work to do. I need to find women beautiful enough to match my husband's bloodline. Oh—and Ty Lee has joined the Kyoshi Warriors, right?

Find a way to capture them. My husband needs a personal guard—women who can service him whenever he pleases."

The official looked momentarily stunned, but quickly bowed again, lowering his head in obedience.

"Understood, Princess."

—

Not long after, Ryuji's letter reached Toph.

She immediately went into a violent rage.

Because with the letter… came a sketch of Ryuji and Azula kissing.

And damning, irrefutable proof.

——————————————————

Meanwhile, Ryuji's body reappeared in Nico Robin's world.

At that moment, Robin was in her study, reading quietly. When she saw Ryuji's form slowly materialize before her, she froze—eyes wide in disbelief.

"Mister Ryuji…?"

She recognized him immediately. How could she not? He was the man who had once given her… experiences beyond imagination.

"Yeah, it's me, Robin. I came here on some business."

He gave her a casual wave.

Robin tensed slightly, on guard.

If he was just here because he wanted her body again, she wouldn't particularly mind. Worst case, she'd create a few clones. Or take the lead herself.

Or just knock him out.

She was a pirate—these things didn't phase her. But because he had once saved her, she was still willing to give him a moment to speak. Watching him carefully, she asked:

"Alright… What kind of business?"

"Mostly just staying in this world for a while. I need to accumulate up energy."

Ryuji wasn't worried—he had already opened his traversal interface upon arrival.

He'd checked the prices. Traveling from the One Piece world to the Naruto world cost 10,000 energy points. To Food Wars, just 1,000. Even Arad was a mere 20,000.

He could accumulate that with time.

What was absurd, though, was that traveling to the League of Legends universe required 300 million points. Absolutely terrifying.

Which meant… even if he'd never handed his tablet over to Azula, he wouldn't have been able to trade it for Lux's virginity after all.

He let out a small sigh—equal parts relief and regret—and moved on to another matter.

Looking directly into Robin's eyes, he asked:

"You're still carrying power from that world, aren't you?"

Robin's expression didn't flinch. She just looked at him, confused.

"What are you talking about?"

She had brought the power back with her.

That ability—to dig massive holes in an instant—was incredibly useful. And the base-building system? Very useful. With that, she could establish strongholds anywhere, explore ancient ruins freely, and never worry about pursuit, danger, or traps again.

This wasn't just a power.

It was power that can save your life.

And no one gives up their trump card willingly.

So, unless Ryuji provided irrefutable proof, Robin wasn't about to admit anything.

"Figures. You're not going to admit it, huh?"

Ryuji sighed.

"Fine. Doesn't matter. Just hear me out."

He extended a hand. A soft, golden glow bloomed in his palm—the radiance of conceptual life energy.

Robin's eyes narrowed. Behind Ryuji's back, silent arms sprouted from her—ready to strike if he made any sudden moves.

"What's your offer?"

"I can revive your mother. Right now. For three hours."

Robin's expression didn't change.

"I can reclaim the power you brought back from that world, convert it into lifespan, and trade it to bring your mother back. I'll take a 30% cut. That's my deal—and the reason I came to find you."

He wasn't wrong. Robin's level had climbed rapidly during the Blood Moon events. Fighting just a few zombies had probably pushed her to level 70, give or take. That translated to around 21 years of conceptual lifespan—more than enough.

He didn't need much. After all, he could convert lifespan on his own if needed.

"I see…"

Robin shrugged.

The deal sounded nice. But she didn't believe a word of it.

"Knew you wouldn't believe me."

Ryuji narrowed his eyes.

"Then… I'll just prove it."

Without hesitation, he crushed the glowing lifespan in his hand—3 hours' worth—and activated the revival.

A beam of golden light shot upward from his palm, spiraling into the sky. Then it exploded outward in a radiant vortex.

A battered woman slowly emerged from the golden swirl, her wounds healing instantly under the divine glow.

Robin gasped.

That woman… was her mother.

Exactly how she remembered her.

She'd only met her once—but that face was burned into her memory. There was no mistaking it.

"No way…"

There was no reason for Ryuji to know her mother's appearance. And if her mother had somehow survived, she would've aged into a frail old woman by now.

But no—this was her mother as she once was. Young, strong, and beautiful.

Impossible.

As the light faded from Ryuji's hand, as he saw Robin's mother open her eyes he quietly stepped out of the room. He sat outside and pulled out his phone to review some languages.

The world here mostly used English, which was why he could talk with Robin so easily—but it didn't hurt to polish things up. His English was… not great.

Inside the room, Robin stood frozen, staring at the woman before her.

The woman—Nico Olvia—blinked in surprise. She looked down at her body, then at Robin.

They looked nearly identical. Only the hair color differed.

"Robin?"

Even though the woman hadn't seen her daughter in so long, a mother's instinct told her immediately.

Robin's eyes filled with tears. Her mother's voice and presence shattered the last of her resistance. She lunged forward and fell into her mother's embrace, sobbing.

Outside, Ryuji heard faint crying and smiled faintly.

Three hours passed.

Robin opened the door with an emotionless face and looked at him.

"How can I trust you?"

Ryuji: "…"

Really? You still want to doubt me?

"Believe me or don't. I don't care. I could use a guide, but it doesn't have to be you."

"This lifespan stuff? I can create it on my own. But for you, it might be… a bit more important."

It didn't matter whether she gave him her "7 Days to Die" power or not. Worst case? He'd have sex with Seria and grind out some lifespan.

That was his survival trump card. As long as he didn't piss off a world's will or a protagonist blessed by fate, he couldn't die. Even if Azula drugged and dragged him away, he didn't worry—he wouldn't die while his conceptual lifespan was active.

As long as he didn't get too cocky or offend the will of a world, death was off the table.

"Is that so…? Then I suppose trusting you is my only option."

"But unfortunately, I'm not ready to bring my mother back yet. Could you… wait a while?"

"How long?"

"Maybe… twenty years?"

"Goodbye."

Ryuji stood up instantly.

He was going to find Nami.

He'd use ten years of conceptual lifespan and some gold to trade for her and her sister's bodies—and extract the energy he needed from them.

As for this emotionally closed-off Robin?

Let her disappear from his story.

"Wait!"

Robin grabbed his arm, turning her face away shyly.

"If you take me with you… if you really help me believe you…"

"Then every day, you can use my butt. I can also use my head or do that kind of thing for you directly"

Ryuji: "…"

You think I care about that?!

Do I look like that kind of guy?!

Thirty minutes later.

"So… you're heading to East Blue?"

Robin asked curiously from the ship's deck.

"Yup."

"That's not going to be easy. Regular routes don't work for that…"

She smiled sweetly.

"But don't worry—we have our ways."

"What way?"

"Hot air balloon."
