One Piece: The user of the Nen-Nen Fruit, who overturned the sea.

With a flap of its black wings, Im soared into the sky.

The air behind him was torn apart, forming a sonic boom cloud visible to the naked eye.

Roy drew his sword, Autumn Water, and his pupils reflected the black figure shooting straight at him.

"regret?"

He chuckled.

"I've never known what regret is."

The moment he finished speaking, Roy rushed out as well.

Two figures collided high in the sky.

Black flames and psychic power exploded simultaneously, causing the entire sky to tremble.

Everyone below paled upon seeing this.

The shockwave from this collision was more than ten times stronger than when Luffy and Loki fought Im.

The sea was shaken so much that it created waves hundreds of meters high, and several warships that were too close were almost capsized.

Tesoro steadied himself by holding onto a broken mast, muttering under his breath, "That monster..."

Roy and Im engaged in a high-speed battle in the sky.

The two figures moved as fast as two black lights, constantly colliding, separating, and colliding again among the clouds.

Each collision generated a violent shockwave, tearing the surrounding clouds to shreds and blasting giant water columns into the sea.

Roy activated his telekinetic domain to try and restrain Im once again.

However, after Im transformed, his body was enveloped in black flames, and Roy's psychic powers were repelled as soon as they got close, unable to entangle his body at all.

Im's black sword grew faster and heavier.

Each slash was enveloped in a solidified, domineering aura, the blade energy stretching hundreds of meters, slicing the forest below to pieces.

Roy dodged left and right, barely keeping up with Im's speed by relying on his Observation Haki and Nen to accelerate.

His clothes had a section cut off, and several holes were burned through his cuffs by black flames.

Im became increasingly aggressive as the fight progressed.

The eyeball ribbons that previously surrounded her were now evenly attached to every corner of her body after the transformation.

As Im attacked, eyes from various parts of his body would open intermittently, unleashing a barrage of incredible abilities at Roy.

While dealing with Im, Roy also had to dodge the various bizarre abilities that would suddenly erupt from Im.

Autumn Water danced in his hands, sparking with black and red lightning.

Roy was forced to retreat repeatedly, his breathing became rapid, and his mental energy was being consumed more and more.

Im realized this and intensified his attack.

"What's wrong?"

Im's voice was laced with sarcasm.

Weren't you being very arrogant just now?

Roy did not reply.

He suddenly sidestepped, dodging a black ribbon that shot straight at him, and then slashed out with Autumn Water, splitting a beam of blue light between the two of them.

Im blocked with his black sword, and the blue light and black flames were locked in a stalemate on the blade.

"I'm just thinking about something," Roy suddenly said.

"What?" Im said coldly.

"How long can you maintain this form?"

Im's pupils contracted slightly.

Roy smiled.

He seized the moment, his psychic power surged, and he forced Im back a few steps.

"You're in a hurry, aren't you?"

Roy continued, his tone so relaxed it didn't sound like he was in a life-or-death struggle.

"You want to get rid of me as soon as possible, because this form is a burden on your body."

Im frowned.

"So all I have to do is stall for time." Roy's smile grew brighter and brighter.

"How long do you think you can hold out?" Im's voice was as cold as ice.

"You'll know once you try." Roy readjusted his stance, with Qiu Shui positioned in front of him.

Without another word, Im flapped his wings and charged at Roy once more.

This strike was even more powerful than before; the Conqueror's Haki on the black blade solidified into a tangible form, like a giant black lightsaber, cleaving straight at Roy's skull.

Roy raised his knife to block.

"boom--!"

Black and blue light exploded in mid-air, and the shockwave knocked Roy down from the sky.

Roy plummeted to the ground like a shooting star, barely managing to steady himself with his telekinesis when he was still dozens of meters from the ground.

When he landed, his feet crushed a large patch of rocks, and a trickle of blood escaped from the corner of his mouth.

Roy looked up at the dark figure backlit in the sky.

Im descended slowly, his black wings stirring up a fierce wind.

Roy wiped the blood from the corner of his mouth and suddenly laughed.

"Good. That's more like it."

Im landed twenty meters away from him, his black sword pointing diagonally at the ground, the black flames on the blade distorting the air.

"How long are you going to keep playing this game? I've already seen through your tricks."

Roy's smile remained unchanged.

"You've seen through it all? Are you sure?"

Im narrowed his eyes slightly.

"Do you have any other methods?"

Roy did not answer.

He flicked his finger lightly on the hilt of the knife.

The blue light on the blade suddenly changed, flowing like water, transforming from pale blue into a deep indigo.

The power of telekinesis and the power of the Soul-Soul Fruit began to merge in an unprecedented way.

Roy said something in a low voice.

What you see through is only what I want you to see.

Robin, who was some distance away, got up from the ground and watched this scene with his lips slightly parted.

She had never seen Roy in this state before.

Not only her, but also Hawkeye, Barrett, Kaido, Ace, and everyone else felt the strange aura emanating from Roy.

"This guy..." Barrett muttered, "he's hiding something too."

Im stared at Roy, the ease in his eyes vanishing.

He knew that the real battle was only just beginning.

Roy's aura suddenly changed.

The surging indigo psychic energy spread from his arm to the Autumn Water Blade, and the entire blade hummed as if it had been infused with a soul.

Im stared at the knife, his black wings trembling slightly. For the first time, he sensed something completely beyond his control in Roy.

"Playing tricks." Im sneered and slashed out with his black blade.

This strike was enveloped in black flames and Conqueror's Haki; the blade's energy resembled a giant black python, slicing along the ground as it lunged towards Roy.

Roy did not dodge.

He swung his sword horizontally, and the indigo blade light crashed into the black python.

The two slashes collided in mid-air and exploded. Roy didn't move his feet, but Im took three steps back.

Im looked down at his wrist; a small wound had split open at the base of his thumb, from which black blood was seeping out.

"That knife you just used..."

"What have you seen through about me?"

Roy interrupted him, his voice carrying a hint of flippancy.

Im's face darkened.

With a sudden flap of its black wings, Im's figure rose from the ground, rushing towards Roy like a black lightning bolt.

Roy did not back down.

He compressed his mental energy to the extreme, wrapping it around the Autumn Water Blade. Every strike he made carried a high-frequency vibration, and the air itself was shredded wherever the blade passed.

The two clashed again.

Black Blade and Autumn Water clashed wildly in the sky, each collision resembling two thunderbolts exploding together.

The ground could no longer withstand the battle. Everyone on the battlefield was forced to retreat by the shockwaves, and even a powerful figure like Kaido had to raise his arm to block the wind.

Im's knife was getting faster and faster.

His strength, speed, and reflexes were all enhanced; each flap of his black wings resembled a small-scale spatial distortion.

An endless expanse of Conqueror's Haki covered the entire battlefield, making his movements unpredictable.

Although still within Roy's psychic field, the influence of Conqueror's Haki...

For the first time, Roy was unable to relinquish his omnipotent control within his own psychic domain.
