We couldn't believe our eyes, at who are we seeing in front of us. It is the Soul of Nature's vessel... And it is...

She wears a dark blue dress with black waves at the bottom, over it she wore a black iron armor... Particularly a chest piece and a pair of pauldrons.

But that hair, that face, that ribbon, that voice and that clothing motif...

"Good one... Me."

"Me!?"

Both of us said that in unison.

"What's going on here...? Why are there two Cirno-Chans...?"

"That answer is simple, My dear Daiyousei. I am the manifestation of Cirno's negativity... In other words, I am her darker half."

"But why would the Soul of Nature pick a dark soul as a vessel!?"

"It was originally intended to pick the positivity as it's vessel, but I managed to steer you off your consciousness, and took over... Separating me, the darkness from you, the light."

"Does this explain why I don't have a dark element?" I asked.

"Not just that... You didn't have earth element as well... I took that earlier than you could! This black ribbon I wore, is the emplacement for the earth element."

"But what is your purpose Cirno-- I mean, Kuro Cirno?"

"Well, I'm glad you're the one who asked that Daiyousei. Seeing as I'm sparing only you in this darkness.... Before you ask, I'm not destroying the world, I'm merely saving it! Everyday we walk towards our self destruction, a new genesis is at hand and I will be the creator! A new world... Without people that will destroy nature"

She took steps forward as she spoke out her motive, I readied Roukanken but then she knocked it off using her sword and Roukanken dug into the dirt.

With no choice left, I have to fight her with the crystallized greatsword. Both of us took our stances, as the world darkens around us.

I swung my sword into her, which she parried easily and she held me by my neck before throwing me to the area behind her, luckily I was able to recover quickly.

"A blade? Try something else!"

I tapped into my water element, and manipulated some of the mountain vapor around me to create a water whip. I used it to lash her multiple times, which she dodged until I managed to get ahold of her sword.

Using my legs as if they were spring, I jumped and pounced onto my darker half, pinning her down to the ground and bashing her face in with my fists a couple of times, before she kicked me off.

Going back into my ice element, I froze the whip before if goes down to the ground, and turned it into a spear which I threw at her. She effortlessly slapped the spear out of the way, and charged forward with her sword held high and going down onto me.

I try to parry her attack with my greatsword, but for some reason she managed to break through my guard, knocking me backwards.

"Try to defeat me, you're only delaying the inevitable."

Conjuring a dagger of ice, I pretended to be hurt, and when she got close I plunged it into her stomach. However she doesn't flinch, and just pulled the sharp blade out without any signs of pain.

"Trying to be sneaky aren't we?"

She then delivers a punch to the side of my head, sending my body to the ground, before she stepped on my head forcefully.

I screamed out in pain, as she just laughed. Looking at a nearby rock, I took it and used all my strength to throw it to her face.

She was then knocked backwards, holding her face as I took the chance to retrieve my greatsword and delivered a swing to the side of her body. However although she was knocked down, she doesn't even get a dent.

"How are you this strong...?"

"Don't you remember that time, when fairies become trapped inside stone cherries back when you first know Piece?"

"I remember that, what does that had to do with anything...?"

"Actually, all the foes you had been fighting, except for Clownpiece who got fooled there... Were all illusions I created, their powers came straight from the originals which I trapped inside."

"And whose power are you abusing by now...?"

"The Oni, of course! Their strength gave me more power and resistance against physical attacks!"

She then used her bare fist to hit the ground and sure enough the ground shook violently, as if an earthquake happened.

"You can't hurt me, Me!"

I ran towards her, and delivered a violent punch to her cheek, which barely made her flinch. Instead it was my hands that felt the pain, not her face.

"What did I just say?"

She then delivered an uppercut to my chin, which then rattled my vision as if I got spun around in a tornado.

I landed on my back, and I slowly got up as I grunted in agony. Can I even beat her...?

She then opened a gap, and went inside it before it closes. Then all of a sudden, I feel her fist hitting me from behind. So she also trapped Yukari into a stone cherry as well...

I tapped into my light element, and chanted "Light Sign - Light gauntlet..." In which my wrist then emits a ray of light, acting as a gauntlet blade.

Closing my eyes and using my intuition, I managed to predict that the next gap opens right behind me, and I thrusted the blade inside, shattering the gap, and revealing her. However she caught the blade with her fingertips, before yanking it off and flicked my forehead with her fingers.

"Just accept your fate already."

It was then when I noticed that the human village began to reduce into rubble and cinders, along with everything else around the mountain.

"I need to end this... But how?"

"Just for your information, I... I mean, we both are now the strongest being in Gensokyo... And the world. Isn't that what you wanted to be... Above everyone else?"

Her words shook me to the very core. I did want to be the strongest... But not in this way! Not by killing off my friends, and ruining the world that I had loved...

Standing up, I angrily gripped my greatsword and raised it up so the blade points at her.

"Did I strike a nerve? What are you going to do now... Weakest?"

That's enough. I dashed forwards with the remains of my strength and raised the blade up high before striking it down, which she tried to parry, but I released my grip on the hilt in the last second, and I kicked her in the midsection which barely made her flinch but she does looked surprised.

"Ice Sign - Great Crusher!" I chanted, as I conjure a huge block of ice, to smash on her.

She attempts to block it, which shatters the block but she also dropped her guard, making me able to hit her in the cheek again, this time by tapping into my lightning element which increases the speed of my punch.

Afterwards I hopped a few feet backwards, and conjured a lightning bolt on my hand before throwing it at her. Afterwards I changed back into ice element and with the greatsword back in my hands just at the right time I manipulated it's shape to change into a smaller sword just for speed.

She managed to deflect the lightning bolt, but was unable to defend herself against my next attack, a thrust to the chest. The blade connects with her flesh, causing her to cough out blood.

Afterwards I pulled it back out and a fountain of blood sprayed across the ground. However she stood back up, and took one of the stone cherries she had... And she changed her sword into that very same weapon Larva used against me.

"You think you're the only one with speed here!? Don't make me laugh."

She then used her time element to stop time around her, to go faster and hit me unnoticed. Knowing that I tapped into my own time element and "Time sign - Clock Up!"

The world stopped in time around us. We fought with our blades across the crumbling mountaintop.

When the spell breaks however, both of us went back into our ice elements in which the both of us struck our weapons together.

However in that strike, we dropped both of our weapons leaving us with only fists.

We delivered fists after fists to our bodies which we either blocked, parried or get hit by.

"I'll end it all... All of sentient life in this world shall perish!"

"The only thing that is going to end is your twisted goal!"

We finally finished off, with a punch to each other's cheeks.

Both of us stood still, breathing heavily from the overuse of energy. We looked again, and we see that her fist had narrowly missed my cheek, while as for mine, I conjured a glove made of ice, not too powerful since my powers are waning to hit her. My fist is connected to her skull, and when she realized it she shook and fell to the ground.

I pinned her down, and hit her across the face a lot of times, before pulling out all the stone cherries she had in store.

"Cirno-Chan! Here!"

I heard Daiyousei calling out, apparently through the whole fight, she used the opportunity to pull Roukanken out from the ground, and tossed it to me.

Afterwards, I caught it and tried to plunge the blade into my dark half's chest. However she caught the hilt of the blade as well and is struggling even though the tip already reached her iron chest piece.

Both of us struggled, until I feel a presence behind me... Daiyousei. She then used her strength to push the blade down, and it pierced through the iron and later her flesh as she struggles by flailing her arms around....

Until she stopped.

We had finally defeated her... But now, to end the incident. From her body, a small light flew out from her heart, and floats above the body.

"What does this mean...?"

"I think... I think it wants you to hand over all your elements back."

I shook. "Why?"

"Because a fairy of an element remains to be that element or else imbalance will ruin the world. As a Greater Fairy... It was already something I know from the start."

I think about it. If I gave back all my other elements to this soul, then I'll return to be the Ice Fairy Cirno... Who is far more weaker than who I am right now.

However, if I refused to give them back then everything will end... But I still have Daiyousei with me.

I am the strongest!

Of course I'll win against Piece, since I am the strongest after all!

I don't need anyone!

Reminiscing those words I once said, I realized how much of a jerk, and a selfish being that I am.

After a moment of thinking, I closed my eyes and let the other 5 elements stored within me return to the Soul, and all of a sudden, my body felt numb... And lose all my strength to move. The last thing I heard is my body's crashing onto the ground.
