Ashen VS Imu

"I'll let you witness the power of a sea conqueror!" Ashen declared while gracefully unsheathing his two swords. Ashen took Zoro's Enma after Egg Head and kept it with him along with Shusui, he did some training and spars with Shiki who thought him how to properly dual wield.

Taming Enma wasn't any trouble at all, and it was a very strong addition as its power was said to be able to 'slice heaven itself' so with Ashen's immense mastery of Haki and his devil fruit ability, his destructive power has increased even further.

The moment Ashen took out Enma, it started releasing Ashen's Armament Haki in excessive amount, forming an intense purple aura around it and Ashen.

"Be a good boy" Ashen said while tightly gripping Enma.

Seeing Ashen's action, Imu took out her sword as well.

"A sea conqueror? Don't flatter yourself, pirates are the lowest of the lowest. I should've taken more drastic measures to cleanse parasites like you from this world" Imu said to Ashen in disdain, she also noticed Ashen's swords "Interesting swords…"

"Let's save the bullshit talk to ourselves, shall we? I'm here to kill you!" Ashen wasn't in the mood to chat with someone like her who apparently has a severe God complex. He immediately infused Enma and Shisui with Haki and solar energy before he unleashed a flying slash towards Imu.

When Imu saw that, she swiftly redirected the slash away using her sword 'Kōki' which means Luminance. It's a Graded and a Black Sword like Ashen's Shusui.

The slash proceeded to cleave the ceiling in half and collapsed on them. Imu was a little taken back by the destructive power of Ashen's attack.

Imu wasn't going to play around or underestimate him, and she quickly started transforming to her Zoan Awakened Form. Her entire body became cloaked in radiant moonlight, emitting a celestial glow that illuminated the surrounding area. Her once human appearance became grand and divine, with silver hair cascading like moonbeams and her eyes shining like gleaming crescents.

As the transformation progresses, a magnificent, feathered cape made of shimmering moonlight emerged from her back, resembling the wings of a divine being. Along with this, a sharp, crescent-shaped tail forms, its tip resembling an arrowhead, capable of delivering precise and devastating strikes.

"Show me what you've got human!" Imu said, a white flame formed a 'mane' down her back and arms, and a stream of floating fire wrapped around her shoulders.

"I see that you're a Mythical Zoan user, as expected" Ashen wasn't surprised at all. Without wasting any time, he proceeded to thrust his sword into the floor and the section of floor nearby Imu turned into flames, and a fast solar beam was unleashed from it and towards her.

She didn't look surprised since she was using future vision and already saw that coming. She calmly used her tail to redirect the attack away again before she turned back to Ashen and pointed her palm at him, and then fired a beam of lunar energy in the shape of crescent at him.

"Lunar Eclipse!" The move is potent enough to slice through buildings with ease.

*BAM* Ashen used his swords to block it before he leaped to the side and got ready for the next attack.

"Lunar? Will I be the first person to kill a Sun God and a Moon God?" Ashen questioned with a sinister smile creeping into his face.

Imu's devil fruit didn't only give her the ability to control lunar energy but also control over gravity to some extent, it granted her enhanced durability, speed, strength and senses on top of the normal physical boost that the Zoan fruits normally give.

"Moonbeam!" Imu didn't give Ashen the time to think of her next move and she pointed her palm at his direction again and fired a ray of moonlight strong enough to send Ashen crashing at the wall behind him.

Imu then Infused her sword with Armament and Conqueror's Haki and launched herself towards Ashen at an extremely fast speed that even with using his Future Sight, he was barely able to react to it before Imu thrusted her sword at his chest in an attempt to stab him.

Ashen swiftly dodged Imu's attack before he tried to slash her in the chest as well. The latter easily blocked the attack before she stabbed Ashen in the stomach with her tail, taking him by surprise.

Ashen shrugged off the pain and proceeded to swing both his swords at her again, delivering massive slashes to her one after another, pushing her back a little bit before he leaped forward and performed an X-shaped slash while releasing a strong blast of solar energy.

"Conqueror of the World…Demon of the Sea Slash!!"

*BAAM* The solar blast caused some damage to her as she looked at Ashen in hostility after that.

"You Zoan users are pretty damn durable" Ashen remarked.

"Silver Moonfall!" Imu raised her hand in the air and summoned a rain of glowing silver orbs that exploded upon impact, scattering debris.

*SWOOSH*-*SWOOOSH* Ashen swiftly dodged before Imu surprised him again with another attack. This time she used her Awakened Ability to unleash a lunar beam from the ground where Ashen was standing, leaving him vulnerable to attacks before she closes the distance between them and slashed him with her sword causing a lot of damage to him.

Ashen groaned in pain before he retaliated by compressing all the flames and solar energy into one small ball and then launched it at Imu before it exploded upon impact while expanding like a supernova.

<Death Ball>

Imu responded by forming a protective shield of shimmering moonlight and protected herself from the intense heat. She then leaped forward at a high speed and managed to stab Ashen in the left shoulder, the latter quickly responded by gathering all of his strength and swinging Enma and Shusui forward, unleashing a devastating energy wave that was fast enough to force Imu to block it, suffering a few injuries while doing that.

The fight between the two would continue for hours with no person seemingly having an advantage over the other one. Ashen was little surprised about her power, he thought she would be a lot stronger than this, but it turns out that just because you lived for 800 year you won't magically get an increase of power, it's always about risking your life and fighting strong opponents.

"Hehehe, you're pretty strong for a lazy ass noble" Ashen said with wicked grin in his face.

"Watch your mouth!" Imu said before she used her gravity power to lift the 19 swords that were thrusted on the floor near the Empty Throne and sent them flying towards Ashen at a blinding spend.

*CLANG*-*CLANG* Ashen used Shusui and Enma to parry and block them before he spun around himself while releasing flames to create a dragon-like tornado that blew away Imu's flying swords.

"Uplift!" When Imu saw that she quickly used her gravity power to lift and suspend Ashen in mid-air, leaving him vulnerable to follow-up attacks, and then she proceeded to jump towards him and thrusted her sword at him while releasing her Haki and a lunar beam.

Ashen threw a mouthful of blood while falling face up on the ground, as Imu's Haki flow inside of his body causing internal damage while the beam caused external damage.

"…Huff…Huff…You got some tricks up your sleeves I see…" Ashen said while slowly getting up again "…But this fight has already dragged on so much, I should put an end to it and to you and then claim my throne already"

"Claiming the Empty Throne? Absurd dreams, but I have to applaud to your effort…no one has ever reached this level before you" Imu stated while slowly walking towards Ashen.

"Hahahaha! You do realize that even if you kill me here the rest will most likely finish you off after that? Just accept you fate…you're fucked!"

Ashen proceeded to lung at Imu using Inferno Jet Steps while also using Observation Killing to prevent her from seeing the future before he raised his Armament and Conqueror's infused Enma and Shusui upwards, solar energy converged around the blades, forming a searing, luminous aura.

With a swift and powerful swing, the blades released a torrent of intense heat and energy, like a comet blazing across the night sky, while a trail of scorching flames followed its path. As the swords struck its target, the immense force of the attack shattered the very fabric of reality, causing a chaotic collapse of matter in its wake.

"Galactic Collapse!!"

*KA-BOOOM* The impact sent shockwaves rippling outward, creating a vortex of blazing flames and disintegrating matter that consumed everything in its path, As the attack concludes, a colossal burst of energy surges upward like a supernova, engulfing the surroundings in an explosion of fiery brilliance.

The attack visibly injured Imu to an extreme degree.

*SWOOSH* Ashen didn't stop there and he quickly jumped on top of her and then swung his swords in a forward descending slash. All the infused Haki used in the technique was released towards Imu, creating a long-ranged slash powerful enough to cut her chest open.

*SPLASH* Imu coughed blood, receiving a lot of damage from those attacks and she was sent crashing into the ground, generating a massive hole on the ground while causing a lot of destruction in Pangaea Castle.

"Huff…How do you like that bitch?" Ashen said with a smirk before he landed in front of her.

"Y-You…lowly human!" Imu glared at Ashen slowly getting up, she looked shaken and damaged from the previous attacks.

"Enough with that already…you and your god complex, you know damn well that you're just a human like me and everyone else, you might fool someone else with that nonsense, but I know the entire history of this word including what you and the other 19 kingdoms did. So, stop being delusional, it is because of that mindset that you're in this bad situation…"

"…I won't make the same mistakes as you did, I won't rule in the shadows and play the 'good guys' and claim to be a god when the whole world knows you're a scum. I'll rule with an iron fist and let my existence known, I'll make it known that anyone who try to do anything funny will end up as a corpse…"

"…there is no room for appeasing any parties, all shall bend to my will. I'll make this world united in my own way. People get drunk on freedom and will eventually start demanding and coming up with weird shit" Ashen spoke from experience of his past life, a lot of countries became degenerate and went downhill because of so many liberties and freedom given to their citizen.

"You think ruling the world is an easy task? the moment everyone finds out what happened here. The world would be plunged in chaos, and everyone will be after your head" Imu said pointing her sword at Ashen.

"Sounds like my life in the past 22 years…" Ashen replied before he swung his swords, sending a powerful flying slash charged with solar energy. Imu used her sword parry it, but the moment she made contact with it, the solar energy exploded.

"…I didn't work my ass off for the past two decades just to get killed here!!" Ashen seized the chance to strike Imu and used his high speed to appear beside her.

"--?!!" Imu was shocked at his speed, Ashen was using Observation Killing and future sight so she couldn't even sense him coming.

He then infused Enma and Shusui with Armament and Conqueror's Haki and proceeded to swing them both diagonally at the same time. But unlike what he normally does, he didn't not only use Internal Destruction Technique with Armament Haki but with Conqueror's Haki as well.

He closed his eyes and focused, he let both types of Haki to blend in and flow inside Imu's body while unleashing a powerful solar blast that was strong enough to send her crashing outside of the castle, before Ashen's Haki caused internal injuries.

"Conqueror of the World…King of the World Slash!!!"

"AGGHHH!!--" Imu's eyes rolled back, and she immediately collapsed on the ground unconscious and drowning in her own blood.

[The battle for the Empty Throne between Ashen and Imu in Pangaea Castle has finally ended…]

[…Winner is…]

[…The 'King of the Pirates' and the soon to be crowned 'King of the World' Ashen!!]
