If it meant her sister could be revived, she would pay any price.
That was Shinobu's current thought.
Her sister was her everything.
Every image of her sister from her life surfaced in her mind.
If she didn't love her sister, she wouldn't have imitated her sister's every mannerism.
Therefore...
When Kaito mentioned this "price", she chose to become his attendant.
"Are you sure?"
Kaito's expression didn't change much. He didn't refuse, not even with a subtle hint.
He wasn't some indecisively kind person, nor was he hypocritical.
If he liked something, he liked it. If he wanted something, he took it.
You might say he was ruthless, but at least he wasn't like some protagonists who put on a show of false sentiment.
If the intention was to take, why beat around the bush?
After all that, wouldn't it still be the same?
Just to make her feel better about accepting?
"I am sure. If you can do it, Mr. Kaito!"
"Alright. Tomorrow, after we go to the Demon Slayer Corps' headquarters and handle Tanjiro's matter, take me to your sister's grave."
"Mm..."
Shinobu was excited, but also a bit down.
She had initially thought Kaito was a good person, but...
No, no, no. The cost of reviving someone was beyond her imagination. So why shouldn't Kaito ask for something in return?
She could refuse!
She was just unlucky that he had found her weakness.
Shinobu's feelings were complicated right now. But she felt Kaito wasn't an utterly evil person.
Besides, based on her understanding of Kaito from yesterday until now, he was actually quite handsome and gave a strong sense of security.
In other words, he didn't hide his intentions, and he had a liking for women, that was all.
Well, well, in this era, anyone with status and power, how many didn't have multiple women?
Thus, Shinobu found it hard to criticize Kaito. She could only say that he had taken a liking to her.
"Don't worry, becoming my attendant won't be a loss for you."
"At the very least, I'm handing over a surefire way to eliminate Demons to your Demon Slayer Corps."
"Tanjiro is your savior. The Demon King, Kibutsuji Muzan, will be slain by him."
Patting Shinobu's shoulder, Kaito smiled and moved on to the second topic.
"Now, does your Demon Slayer Corps know anything about Nakime?"
"Nakime?"
Shinobu looked puzzled, and Kaito got his answer from her expression.
It seemed not many knew about Nakime, or perhaps no one did.
That made sense; knowing about Nakime meant you were close to finding Muzan.
Also, with Nakime's ability, finding her was truly difficult.
But then again...
The more difficult, the more Kaito liked this ability.
It was a spatial ability, even if somewhat different. At least, Kaito currently had no abilities related to space or time.
Because he lacked them, he wanted them.
Even if his strength was great enough to slightly alter time's flow or break fragile spaces, what use was that?
It wasn't the same as truly mastering time and space.
Therefore, Kaito had set his sights on Nakime's Blood Demon Art, especially its convenience.
Combined with his own Supreme Jade Chamber...
They could complement each other perfectly!
With a snap of his fingers, he could reside in the Jade Chamber, or bring someone from afar, then send them back.
Effortless.
If he could influence the chat group, allowing members from other worlds to come through this ability, that would be wonderful.
Whenever needed, they could meet directly, without spending points to travel. Currently, every visit felt like a formal gathering.
So...
This ability was truly useful.
Ah, that's assuming it could reach that level.
If not...
Then upgrade it!
He had A-Class Upgrade Cards, S-Class Upgrade Cards, SS-Class Upgrade Cards lacking fragments, similarly for SSS-Class.
Considering he would later go to Sephie's world to become the universe's overlord, he would surely fight several cosmic battles. Wouldn't streaming that net him a ton of points?
Repeated godslaying didn't yield many points because it was a repetitive event.
But cosmic battles would certainly be the freshest events!
"It seems you don't know either. But your headquarters might have some information. We'll ask around tomorrow."
"Alright... I'm sorry."
"No need. Nakime's Blood Demon Art is very special."
With the second matter concluded, Kaito ended the conversation.
The main reason for the private talk was Kanae.
"Um... Mr. Kaito, about Tanjiro... can he really kill the Demon King?"
As Kaito turned to leave, Shinobu asked the question that concerned her most.
Killing the Demon King was the ultimate goal of the Demon Slayer Corps.
But to this day, they hadn't even killed the Demon King; they could count the number of Upper Rank Demons slain on one hand.
And their Demon Slayer Corps?
Countless Hashira had died.
Now Kaito claimed Tanjiro could kill the Demon King, which was even harder to believe than his ability to revive her sister.
Because Kaito was from another world with magical powers, reviving someone had a sliver of credibility.
But Tanjiro?
He was clearly from this world, seemed like an ordinary person, and had only barely grasped a concept in one afternoon, still unable to fully grasp the basics.
"Yes, because he has mastered Sun Breathing. Though it's an adapted version, a weakened one, I have enhanced his physical constitution. So even in its weakened state, it's enough to kill Kibutsuji Muzan. You just need to train him well."
"Su, Sun Breathing!? Is that true!?"
"Of course! That's precisely why I'm entrusting him to Rengoku Kyojuro. I also need Water Breathing to balance it."
"I-Is that so... If that's the case... could our Demon Slayer Corps members also learn Sun Breathing?"
Having one person with Sun Breathing was a great trump card against Muzan.
But if all Hashira mastered Sun Breathing, their chances of victory would be much greater!
Every Hashira could be a trump card!
"No, but you could try. You never know."
"Besides requiring a strong physique, it also depends on whether you have the opportunity to master it."
Rengoku Kyojuro could try, but those who had already mastered other Breathing Techniques? It was very unlikely.
