Nezuko: We finally met. Shinobu: You are the king of Oni. Mitsuri: Kibuchiji Mujan!

Nezuko: We came here to stop you and avenge the humans! You can not turn innocent people into Oni anymore!

"Hey! Let them go! This has nothing to do with us!" says Nezko as he transforms into his Oni form, but retains his human nature. He stands between Shinobu and Mitsuri. "You don't have to turn us into Oni too!"

As he defends them, Shinobu shakes off the dizziness and sneers at Onidul. Her fists begin to glow blue as she prepares to attack. Meanwhile, Mitsuri readies her whip-like katana, its handle covered in Oni tattoos. "Don't think you can manipulate us so easily!"

Nezuko takes a step back when his head turns orange and black horns sprout on his head.

No! I am still a human being inside!

She roars, and strength springs through her body. Shinobu shines brighter than ever and fights with Onidul, but is being pushed back. Mitsuri wields a whip-like Katana precisely and quickly, but as the Oni tattoo hits the Katana behind him, he is gradually being pushed back by Oni.

"I-if this is what you really want...!"

Nezuko's orange and black hair gets thicker and thicker, and sharp horns sprout all over his body. When his power skyrockets, it is clear that she will be completely corrupted and cannot fight for so long.

Shinobu is invaded by an Oni tattoo, and she fights against the Oni Legion, but is gradually pushed back.

Mitsuri fights with Katana, but when Katana is completely eroded by Oni tattoo, she is unable to use Katana and is gradually being pushed back.

Mitsuri stumbles back and Katana crunches to the ground.

"I can't fight anymore..."

She had an Oni tattoo that ruled her soul.

And suddenly, a flash of light comes out of where Mitsuri stands. It becomes clear that the power of shock waves causes Nezuko and Shinobu to fly back, and has transformed into the perfect Mitsuri Oni. her eyes glow like dark rubies her oni tattoo twists and moves with dark energy she radiates a distinct aura of vivid power

Mitsuri stands tall in the form of a new sludge, and her new power has long, whip-like tentacles. Mitsuri, who once had green eyes, now has dark green eyes. And she approached Muzan.

Mitsuri eventually went to Muzan, and knelt down to Muzan and clung to loyalty.

"Mitsuri: Yes, okay, Muzan-sama." Mitsuri binds them with tentacles, puts them in their mouths, and corrupts them with Oni.

Nezuko and Shinobu were both struggling against dark tentacles that wrapped around them and spread their jaws wide, but they couldn't get out. mitsuri reluctantly forced his tentacles into his mouth and seized his loyalty to muzan and surely corrupted them to oni

Nezuko grunted with his teeth clenched, feeling the disappearance of humanity every moment. Shinobu clenched his fists tightly and wept on his cheeks as he fought for control of himself. But it was a losing fight.

And they fell into Oni.

They said nothing. Their minds were corrupted and ruled by Oni. They followed their creator Muzan and became his loyalists. and now there was no human character left in them at all now nezuko shinobu and mitsuri were no different from any other oni as the loyal woman oni of muzan

They followed Muzan like lost souls, their humanity completely forgotten as they became loyal minions to his twisted will. No longer were they the kind and caring individuals they once were; instead, they now embodied the monstrous force that would help him achieve his sinister goals.

It pained them deeply to see themselves transformed into such beings, but there was no escaping the power of Oni's corruption. As Muzan led them deeper into the world he had created, they found solace in their newfound strength and the sense of belonging it brought them... all the while aware that this acceptance came at an unimaginable cost.

They nodded silently and followed Muzan, their eyes empty as they prepared to wreak havoc on the world around them. No longer were they human; they were now creatures of darkness and destruction, bound by chains of blood and loyalty to their new master. The path they had chosen would lead only to further corruption and suffering, but it was a fate they could no longer resist.

The three women said nothing but nodded obediently as they continued to follow Muzan, their hearts filled with despair and the desire for revenge against him for what he had done to them. They knew that if they were to ever break free from his control, it would mean sacrificing everything they once were, including each other; yet, a faint spark of hope still burned within them, reminding them not to lose themselves completely in the darkness.

As they walked side by side with their new master and allies, they could feel themselves changing further into creatures of Oni's design - becoming stronger, faster, more brutal; yet somehow also more hollow and helpless at the same time. It was a horrifying duality that threatened to consume them entirely unless something dramatic changed their course in life.
