My Overpowered Bunny Girls

Chapter 6: 6. Legion of Bunny girls

Nathan returned home not long after Professor Helena finished dealing with the incident outside the academy.

Thankfully, before dismissing him, the professor had made one thing very clear.

He would not be held responsible for what happened.

Which honestly made sense.

Reid had illegally borrowed a C-Rank summon, lost control of it, and nearly caused a full disaster right outside academy grounds. Compared to that, Nathan technically counted as the victim in the situation.

Still...

Nathan had noticed the suspicious look Professor Helena kept giving Mirko before he left.

That woman was definitely going to keep an eye on him from now on.

Nathan sighed quietly as he unlocked the apartment door and stepped inside.

Home was small.

A cramped little studio apartment located within one of the city’s cheaper districts. The kitchen and living space practically blended together while a thin partition separated the sleeping area from the rest of the room.

It wasn’t luxurious, not even close. But despite its size, the apartment still felt... warm.

Although the parents of this body were gone, Nathan wasn’t completely alone in this world.

There was still one remaining family member.

lucy.

His little sister.

Truthfully, Nathan still didn’t know how to properly interact with her.

In his previous life, he had been an orphan who mostly kept to himself. Between content creation, streaming, training, and grinding through life, he never really learned how to handle family relationships.

Especially not younger siblings.

So during the past two months after transmigrating into this world, Nathan had mostly just been pretending.

Pretending to be the brother lucy remembered. Pretending to naturally understand memories that weren’t truly his. Pretending this life genuinely belonged to him.

And yet... Even though this heart wasn’t originally his... Nathan still found himself caring about lucy far more than he expected.

Like some lingering emotions from the original Nathan Cross still remained buried somewhere inside this body.

"Brother! You’re back!"

The moment Nathan stepped through the door, lucy rushed toward him excitedly.

Her bright eyes sparkled with curiosity as she nearly bounced in place.

"How was your summoning?!" she asked eagerly.

Nathan smiled faintly.

Without saying much, he simply raised his hand.

A small summoning circle appeared beside him.

Mirko materialized instantly.

"AWWWWWWN!!!"

lucy’s reaction was immediate.

"It’s SOOOOO cute!!"

Before Mirko could even process what was happening, lucy scooped the tiny bunny into her arms and hugged her tightly against her chest.

Mirko’s pink eyes widened dramatically.

’Master!’ Mirko’s voice echoed inside Nathan’s head in complete alarm. ’Who is this tiny bundle of joy?!’

Nathan almost laughed.

’My little sister,’ he replied mentally. ’Keep her occupied for me.’

Mirko immediately straightened proudly inside lucy’s arms.

’Understood, Master! I shall handle this dangerously cute opponent!’

Nathan ignored whatever nonsense she planned to do and quietly walked toward the corner of the apartment before sitting down.

Then his expression slowly became serious.

His attention shifted inward.

Toward the system. Actually... Systems.

Nathan currently possessed two different status panels.

His own and Mirko’s.

Both of them had changed after the battle earlier.

[Ding! Conditions have been met!]

[Sharp Eyes Lv.1 has leveled up to Sharp Eyes Lv.2]

[Ding! XP Gain Detected!]

[Mirko has leveled up!]

Nathan’s eyes narrowed thoughtfully as he read through the notifications. Skills really could improve through repeated use.

That was already useful information that they were taught in school.

But compared to the thing truly occupying his thoughts right now...

It barely mattered.

Nathan leaned back slightly against the wall.

"System," he called quietly.

Silence.

"Answer me."

If anyone else in this world heard him talking to empty air, they would probably assume he had gone insane.

The ordinary system that humanity used wasn’t sentient.

It simply displayed information: Levels. Skills. Status. Tower notifications. Nothing more.

Only the upgraded versions found inside certain Towers possessed limited guidance functions capable of offering hints or navigation assistance.

But this thing... This Bunny Girl Summoning System... it felt fundamentally different.

Nathan’s eyes sharpened slightly.

"I said," he repeated firmly, "answer me."

For several long seconds, nothing happened. Then...

[...]

[What does Host wish to inquire about?]

Nathan’s breathing paused slightly.

At that moment, Nathan fully realized something important.

This wasn’t just some ordinary cheat ability. free𝑤ebnovel.com

A responsive, intelligent system entity?

That was absurdly rare.

In practically every manga, anime, novel, or game Nathan consumed in his previous life, sentient systems were always special existences.

Dangerous ones too.

Nathan slowly steadied himself.

"Explain what you are," he said carefully. "And your purpose."

The system paused briefly before replying.

[...]

[I am merely a guide to this system.]

[That is both what I am and my purpose.]

Nathan frowned immediately.

"Semantics," he muttered.

Then he crossed his arms.

"Fine. Then explain the Bunny Girl Summoning System itself. I refuse to believe this thing is just some weird perverted gimmick."

A brief silence followed. Then...

[The Bunny Girl Summoning System is a shard of blessing left behind by The ******** Lord.]

Nathan suddenly winced.

The moment the word before "Lord" entered his mind, it became distorted by an unbearable static sound.

Like reality itself was forcibly censoring it.

Nathan’s expression immediately changed.

"...What?"

[The ******** Lord.]

The same distortion echoed again.

[...]

[The Host currently lacks the authority required to perceive the full designation.]

Nathan stared blankly for a moment before letting out a dry scoff.

"Yeah," he muttered sarcastically. "Sounds about right."

Then he pointed toward Mirko.

The bunny was currently bouncing around the apartment while lucy chased after her excitedly.

"Forget the mysterious censorship nonsense for now," Nathan said.

"Explain her to me."

The system replied immediately this time.

[The Bunny Girl designated "Mirko" is one of many lost souls belonging to a powerful Demi-Beast race that fell during their era of Babel.]

Nathan’s eyes narrowed slightly.

Babel, that name.

The exact same word engraved onto the gigantic Towers scattered across the planet.

Two hundred years ago, the world had still been normal.

Then the Towers appeared. Alongside monsters. Alongside mana. Alongside the System itself.

Some Towers contained entire worlds within them. Others possessed endless dungeon-like floors filled with creatures and treasures.

And if left uncleared for too long... The Towers would begin leaking monsters directly into reality.

Nathan slowly exhaled. "...There’s that phrase again."

He glanced toward Mirko. "Powerful race."

Then another thought suddenly struck him.

"Wait."

Nathan frowned slightly.

"Mirko mentioned having a compact form earlier."

"And her status panel includes a Class slot."

Nathan’s eyes narrowed further.

"Summons aren’t supposed to have classes."

The system answered immediately.

[The Demi-Beast Bunny designated "Mirko" has been stripped of the power she possessed during her previous existence.]

[It is the Host’s responsibility to guide her growth.]

[Her future abilities, combat specialization, evolutionary path, and overall potential shall be determined by the Host.]

Nathan’s heartbeat slowly accelerated.

Then another notification appeared.

[Upon reaching Level 10, Mirko shall evolve into E-Rank and obtain a humanoid form.]

Nathan’s eyes widened slightly.

The system continued.

[At that stage, the Host will gain the ability to assign an appropriate class.]

[All Bunny Girls summoned through this system possess the potential to obtain classes.]

Silence filled the apartment.

Meanwhile, in the background, lucy was currently holding Mirko upside down while the bunny squealed dramatically in confusion.

Nathan barely noticed, because his thoughts were racing.

Classes. Evolution. Humanoid forms. Limitless growth potential.

And then the realization truly hit him.

If his summon limit increased in the future... If he could summon more Bunny Girls... if every single one of them could evolve, gain classes, and continue growing stronger...

Then what he possessed wasn’t just a summoning ability. It was an army.

A legion of evolvable Bunny girls capable of wielding countless classes and combat paths: Warriors. Mages. Archers. Assassins. Support classes. Tank builds. Special classes.

And unlike ordinary summons... These ones possessed infinite evolutionary potential.

Nathan slowly looked down at his trembling hand. Then, little by little, a grin spread across his face.

This was his true cheat.

Not dragons. Not phoenixes. Not legendary demons.

But something potentially far more terrifying.

A legion of Bunny Girls capable of reaching limitless heights.
