I'm going to use it, the power of Spirit Fusion's Skill.

[Spirit Fusion: Lv10 (Max Level)]

An Ultimate Ability for Spirit Farmers. Grants the ability to Fuse Spirits together even more smoother than through using other methods such as Spirit Enhancement. Fused Spirits will result in even stronger Spirits with powerful attacks, spells, and skills. Depending on the type of spirit, they might remain fighting for up to five minutes or disappear once they unleash their single powerful attack/spell. Additionally, there's a 50% chance for the Spirit Fusion to be a [Super Success] which will bring out an even stronger Spirit to battle, or to assist you in combat. The Power of Fused Spirits depends on Skill Level, MP cost is reduced based on Skill Level.

It was now or never!

"[SPIRIT FUSION]!

The power of Spirit Fusion began to overflow from across my hands, as over a hundred Lesser Spirits and Dragon Vein Elemental Spirits came together into a single form.

FLAAASH!

Hundreds of colors, it was as if the very rainbow gathered within the palm of my hands!

A beautiful entity emerged from within the fusion of over a hundred Lesser and Dragon Vein Spirits!

It resembled a beautiful lady with light skin and eyes shining like rainbows.

Her long blonde hair extended to her feet, and she wore no clothes, her blonde hair cover her entire body.

She had no weapon or anything, but instead was holding a large and beautifully decorated jar with rainbow water inside.

[You have Fused over a Hundred Spirits to create [Aquarius, Grand Spirit of Purification]!]

"A-Amazing"

She suddenly looked down at me with a gentle smile.

[Aquarius, Grand Spirit of Purification] recognizes your strength and your pure heart and requests you to use Spiritual Infusion with her.]

It can even talk to me in such a way?

"Alright then Spirit Infusion!"

FLUOOOSH!

Aquarius suddenly turned into pure Spiritual Essence and fused into my body!

FLAAAASSSHHH!

A powerful aura of water and rainbow light emerged from within my entire body.

But not only that, my own appearance began to change?!

I felt like my eyes suddenly began shining brightly, as my clothes changed into a long white dress, my skin was covered by countless blue runes showing flowing water, and my hair became blonde like her.

Suddenly, my weapon turned into this enormous Jar holding this strange water!]

"Uwaaah?!"

I felt slightly shocked but I really didn't had the time to think, she gave me her power, I must use it to defeat the Demon King already!

"Use my power"

Suddenly, I heard Aquarius gentle voice echoing within my mind.

Information flowed into my mind, as I felt the power of not only nature but water flowing across my body!

"[Water Step]!"

I stepped forward into the air, each step felt as if I was walking over small droplets of water!

"Uwaah! I can just walk in midair!"

And then!

"[Spiritual Water Flow]!"

SPLAAAASH!

Water suddenly surged from [Jar of Endless Spring Water] and shaped into a current, carrying me rapidly towards the Demon King's Phantom!

FLUOOOSH!

"YOU!"

The Demon King Phantom greeted me with a furious glare, his countless red eyes began to grow bigger as they shone with bright red light.

"I'LL END YOU!"

His very Phantom opened its eyes, shooting red beams at me capable of piercing through anything!

BOOOM! BOOOM! BOOOM! BOOOM! BOOOM!

However, the Water of the Jar emerged, suddenly beginning to dance and coil across the skies, resembling a furious sea snake.

And then, it directly hit the Demon King's Phantom!

SPLAAAASH!

"UUNNGGH! AAAAGGH!"

"You really don't give up, don't you?!"

I looked at him furiously, as the water I was able to control at will suddenly shaped as countless of spiraling vortexes, hitting the Demon King Phantom constantly!

SPLAASH! SPLAAASH! SPLAAASH! BOOOOOMMM!!!

"UNNNGGH! What does a mere puppet of the Gods like you know about my will, about my desires?! They're far BEYOND your mere understanding!"

His entire Phantom resisted my attacks barely, as he shaped countless tentacles made of shadows and his very soul, wrapping them around my body!

CRAAASH!

"UAGH!"

His tentacles not only wrapped around my body and limbs, aside from restraining me, they began draining my HP and MP rapidly! His eyes slowly approached my face, as his monstrous jaws began to speak with his tenebrious voice.

"You're nothing but an insect, pointlessly struggling without knowing what you're even fighting for!"

"Unnggh W-What do you even know about me either?!"

"I know for sure that you're merely a pathetic existence!"

"You're just filled with yourself! You love to talk like nobody comprehends your oh so magnificent plans, but they're just genocide! You're a monstrous being!"

"And you're a god puppet! What do you know about being dejected?! About being abandoned, alone?! I want it all! I will take everything the gods love about this world, it'll be mine! And then"

FLAAASH!

Suddenly, a portal in space opened right in front of me, cracking the walls of space and time, and showing the city where I lived

"I will take yours as well"

"No!"

"I will devour them all!"

"Stop"

"I will throw your world into endless Darkness!"

"Agh!"

"Your loved ones Your family, your friends I am going to enjoy eating them alive, one bite at a time!"

"YOU WON'T!"

FLAAASH!

I roared with fury, as my weapon which has transformed into the Jar of Endless Spring Water trembled, a downpour of rainbow-colored water emerged, shaping as a furious Kraken, and then extending its tentacles and fighting against the Demon King's ones!

CLAAASH! CLAAASH! SPLAAAASH!

"Unnnggh! You're still fighting while thinking you can win?! My soul's indestructible!" The Demon King roared back.

"Let's see about that! Great Spirit! I'll use your power with Spirit Fusion and Spirit Infusion!" I said angrily.

"Wait, what?! We haven't practiced that yet! Elayne!"

The Great Spirit tried to stop me, but I was desperate!

"[SPIRIT FUSION]! [SPIRIT INFUSION]!"

FLAAASH!

Suddenly, I felt an endless amount of Spiritual Essence flowing towards my soul and body, combining with Aquarius, and creating something completely new!
