The Ruthlessly Cruel Flea Assassin

The bathroom. My surroundings had long since transformed into a horrific slaughter scene.

Five fleas, including those that had died at the beginning, were scattered around the bathroom, split in half and writhing in various places.

"Chonggong, please rest in paradise."

I tore off a bit of toilet paper and used it to bury the 'flea that was' together.

Swoosh swoosh swoosh.

With the sound of the toilet flushing, the corpses of the fleas disappeared forever.

I know that too.

After all, no matter what, those vicious fleas will swarm again in a few days.

But thanks to that, it seems I've learned a little about my body, so I'll take that as satisfaction.

First, one definite thing.

This body seems to have high killing power against living things.

The test subject was just fleas, but still.

I have never heard of the level of swinging my hand to slash bugs.

If unsure, I could ask in the gallery too.

Of course, not knowing is just an excuse, and in reality, it's just showing off.

Then suddenly the post disappeared.

"Ah!"

I got hit!

The post that had received the most attention in my life vanished in an instant!

I hadn't posted any weird meme or violated any rules, so it couldn't have been deleted by some bot.

So the answer was simple.

Someone had used my password to delete the post!

I had set it to 1111 because remembering a password was annoying, and that had been my mistake.

Just one silly post deleted, yet it strangely hurt my heart.

I won't cry.

I won't cry.

"Too much..."

Someone once said that the mind follows the body.

I finally understood that saying was true in this moment.

I knew rationally that I was nothing special, but with my difficult situation and changed gender, my sensitivity had become so rich that tears filled my eyes over something so trivial.

I opened the faucet and washed my face with cold water repeatedly until I finally calmed down a little.

From now on, I probably need to prevent posts ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠from being deleted.

It's inevitable...

I probably need to change my fixed nickname.

With a fixed nickname, unless I post some creepy image, posts won't be deleted by others.

I pondered what nickname would suit me.

Probably something that comes to mind without much thought.

[Dangdogyeon]

So my gallery fixed nickname became Dangdogyeon.

A silly nickname, but my heart was satisfied.

Anyway.

Seeing Kim Seonghyeon's reaction as Korea's top swordsman, it seemed the realm of slashing objects with hand edge, or the path of formless sword, hadn't been reached even by him.

But this body had done it with nothing more than fleas.

Moreover, this didn't seem to be a skill!

[Name: Ban Jisu]

[Class: Assassin (SSS)]

[Skills]: Stealth, Detection, Assassination, Continuous Action

Among the skills I had, I had only expected Assassination at best.

This was clearly not Assassination but Flea Slaughter, no matter who looked at it.

So, I guess this was just what my body could naturally do to this extent.

Thinking of it, I wanted to try other skills too.

How should I use them?

Did I need to chant a spell?

If so, let's chant the spell I had always wanted to try once.

When I was little... no, not now.

Before I changed like this.

When I was little.

Before the Great Inundation.

In the bookstore where even stationery stores sold books, the magic spell used by the cool thief.

"Sky ping, star land, transparency, transform, yip!"

I spread both arms wide and chanted the spell.

Nothing happened.

Well, that was enough for a joke.

This was a big problem.

Ever since my body changed, I kept doing weird things without realizing it.

"...Stealth."

I quietly chanted the skill and my body became transparent.

The pink-haired girl's figure inside the mirror vanished without a trace.

How to release it? I pondered for a moment.

Releasing was easier.

Just by thinking, Stealth ended and the pink-haired girl's figure reappeared in the mirror.

The pink-haired girl was so happy she was smiling from ear to ear.

Then... next was Detection.

"Det... no. Later."

I had been about to chant Detection but stopped because of a bad feeling.

Even without using the skill directly, I could already feel the tiny bugs flying around in my room.

With this much sensitivity without directly using the skill, what would happen if I boldly chanted Detection?

I didn't know what kind of trouble I'd get into.

...I'll try Detection later.

Then the only remaining skills were Assassination and Continuous Action...

Fortunately, Continuous Action was a skill I had seen in the gallery.

The owner of the skill was none other than Kim Seonghyeon, who had commented on my life's best output of "How much do I need to be to slash objects with hand edge?"

Because of that, Kim Seonghyeon, who had boasted in the sacred gallery, had to return ten pieces of chicken.

I ate it too.

That chicken.

It was delicious.

Maybe because someone else bought it for me.

Yes.

That was exactly Continuous Action.

The skill that dropped from the skill book obtained after barely subjugating the disaster-class boss monster Bulgasari was something I, an SSS-rank Assassin, had naturally possessed!

Although I couldn't use it as well as the person who called himself "The Man Who Will One Day Become the Sword Saint."

But just knowing that person had the skill made me burst into silly laughter.

Then the only remaining thing was Assassination.

How was I supposed to test this really...

I didn't even have the courage to try it.

But a strange intuition kept filling me with baseless confidence.

It would be fine.

...Well, it couldn't be helped.

Fleas.

Although I was a vicious Flea Extermination Association member with no heart or tears, I felt a bit sorry for them this time.

But it couldn't be helped.

This time, you had to sacrifice yourselves.

I left the bathroom and searched my room for the fleas wandering around.

This time, I really relaxed a little and lightly swung my hand like a bed.

Then a disgusting itch continued to be felt on my palm.

Success.

Now, I'll say to the one caught in my hand.

"Assassination."

"Aha."

As soon as the thick status window text appeared, I caught on.

How to activate Assassination.

I gently opened my hand.

The flea, avoiding me, staggered toward the bathroom.

I watched quietly, then confirmed the flea's presence stuck to the bathroom wall and activated Stealth.

I slowly walked over.

Without trying to move silently, no trace came from my body.

In that state, I reached the bathroom.

The flea was still stuck quietly to the bathroom wall.

I took out the toothbrush stuck in the toothbrush cup.

After all, the bristles were worn out and it was time to throw it away, so it was fine to use it like this.

I aimed the toothbrush not at the bristles but in the opposite direction at ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠the flea.

The toothbrush floated in the air as if it wasn't judged as part of my body.

But the flea still didn't know what was happening.

There wouldn't be anything to know in the future.

"Assassination."

Thud—

As the tip of the toothbrush handle touched the wall,

My eyes, strengthened upon awakening, clearly saw it.

The flea's body bursting as it touched the toothbrush.

This was definitely it.

The activation condition for the Assassination skill.

The target had to not detect my existence.

So, had I roughly figured out all the skills...

But, a little...

"Self-loathing..."

How could an SSS-rank Assassin test subject be a flea?

I knew it was unavoidable!

But...

Feeling self-loathing was also unavoidable.

At that moment.

The status window that was supposed to never appear suddenly appeared before me.

Ah.

Ah.

...In less than a day since awakening, I had become the ruthlessly cruel flea assassin through the system official.
