Kanae's beautiful face was amazed. Giyu still had no expression, but his eyes showed surprise.
They could both feel Aoki's aura had grown much stronger.
It wasn't a secret among the Demon Slayer Corps' leaders that Mr. Aomura could grow stronger by devouring demons.
He had just devoured Upper Moon Two. It was normal for him to get stronger.
They were shocked by how much stronger he had become.
Kanae suddenly thought, "If he devours enough demons, could Mr. Aomura become stronger than Muzan?"
She was startled by her thought. Her heart beat faster, but she calmed down quickly.
"Mr. Aomura is a demon too. It's probably impossible to surpass the first demon... right?
But demons get stronger by eating humans. I've never heard of a demon getting stronger by eating other demons. Mr. Aomura is special. Surpassing Muzan isn't impossible..."
Kanae realized Mr. Aomura seemed to have "digested" Doma. She shook off her thoughts. "Mr. Aomura, what should we do next?"
Aoki thought for a moment. "I'll rest somewhere. I'll look for Tanjiro tomorrow."
The fight with Doma had used a lot of his energy.
Especially using Feast twice.
It was his ultimate move.
The power came at a terrible cost.
Just the twelve Space Traverses used a lot of stamina and mental energy.
The Feast used even more energy than normal Space Traverse.
But his stamina had recovered after devouring Doma. Resting was just an excuse. He really wanted to study space marks.
Level 2 Space Traverse was almost a new skill.
He was excited and couldn't wait to try it.
Tanjiro's family wasn't going anywhere.
One day sooner or later didn't matter.
Giyu nodded silently, agreeing. He didn't say a word.
Kanae smiled. "Then you should rest, Mr. Aomura. We'll take care of things here!"
Mr. Aomura had defeated Upper Moon Two alone.
She wouldn't object to anything he wanted, even if it was unreasonable.
Aoki added, "Miss Kanae, I want to meet Master Ubuyashiki when you get back."
"Meet Master?" Kanae looked curious, but she didn't ask. "I'll tell him."
"Thank you!"
Aoki said.
He agreed to meet Giyu tomorrow, then left alone.
...
Muzan's long hair flew wildly. His face was fierce, veins bulging. Tendrils stretched from his back.
The ground broke, buildings collapsed.
People ran away in terror.
The busy street emptied quickly.
"Traitor!"
Muzan said slowly, his voice like ice, full of killing intent.
The traitor had teamed up with the Demon Slayer Corps. The rate of demon deaths had increased.
He didn't care about demons. He didn't want to increase their numbers.
But he needed demons to find the Blue Spider Lily and the Ubuyashiki family.
He was already angry about the demon deaths.
Now, Doma was dead too!
He didn't like Doma, but Doma was his Upper Moon Two, his second-strongest demon.
The spot Gyutaro had left was still empty. Now, another Upper Moon was gone.
He felt his system collapsing.
It was all because of the traitor!
Unlike the Demon Slayers, or even that monster from the past, the traitor was a demon. He had endless life.
The traitor's threat wouldn't disappear.
"The traitor must die! And his secrets will be mine!"
Muzan's fierce expression calmed, but the killing intent in his eyes grew stronger. He vanished.
Infinity Castle.
Nakime held her biwa, sitting on a high platform. Her long black hair fell on both sides, hiding half her face, showing only her small nose and delicate mouth.
Muzan appeared beside her.
Two Upper Moons were gone. He had to replace them quickly.
But demons with the potential to become Upper Moons were rare.
He had been looking for a replacement for Gyutaro, but he hadn't found anyone he liked.
No, there was one.
Muzan looked at Nakime.
She was the most likely demon to become an Upper Moon.
If she could withstand a lot of his blood, her power would increase quickly.
But if she couldn't, she might die.
Nakime controlled Infinity Castle. She was important to him.
If she died, Infinity Castle would collapse. It would be a huge loss.
Muzan watched Nakime silently, his pale face expressionless, but the killing intent and rage in his eyes grew stronger.
Pfft!
He suddenly raised his hand, stabbing his finger into Nakime's forehead. Blood spurted from his fingertip.
Muzan's voice was emotionless. "Nakime, if you can survive, I'll make you an Upper Moon."
The traitor had to be stopped. The problem wouldn't go away. It would get worse.
He had to stop the traitor's ability to escape.
The last time had shown that he couldn't kill the traitor without stopping him from running.
Even if he fought himself.
The only way to stop the traitor's ability was Infinity Castle.
Infinity Castle was a separate dimension, limited in size, and controlled by Nakime.
If the traitor entered, he would be a rat in a cage.
But first, he needed to strengthen Nakime's power, increase her control over Infinity Castle, and use her ability to search for the traitor.
Pfft!
Muzan pulled out his finger.
"Ah!"
Nakime screamed, her neck stiffening. She looked up sharply, her hair falling, revealing her face.
Below her nose, she was human. But above that, a single, egg-sized eye was set in the center of her face.
"Heh heh!"
Nakime's body twitched.
Veins spread from the eye, covering her face.
Her hair became like living tentacles, swaying and merging into the wall behind her, spreading out to form a twisted pattern.
Rumble!
Infinity Castle shook like an earthquake. The ground cracked.
Nakime's aura grew stronger.
After a long time, Nakime stopped struggling. The shaking stopped.
She looked up, showing her veined face. The single eye in the middle had the character "Six" in it.
