Without hesitation, Kaito killed Nakime and used the card he obtained. A faint gray light gradually turned pale gold, integrating into Kaito's body without any side effects.
Since Kaito wasn't a Demon, the system thoughtfully converted it into an ability suitable for him.
"I see... the Spatial Gate ability..."
It was akin to something like a spatial gate.
First, Kaito could carve out his own space. Within this space, he could build his own domain. Once completed, he could freely alter the facilities inside.
It was like the scenes in Inception, changing at will.
You might be walking on the floor, but with a single thought from Kaito, you could find yourself walking on the ceiling, while Kaito remained on the floor below.
Within this space, gravity still functioned normally. But under spatial dislocation, even if you jumped from your perspective high into the air and touched the floor beneath Kaito's feet, you would still land back in your original spot.
It wasn't that reaching Kaito's position meant you could stand beside him.
Because the spaces' gravities were separated, and his designated location was also different.
As for the gate, it could be opened arbitrarily. He could change its direction, use it for teleportation, and more.
"The Infinity Castle is gone?"
Perhaps the Infinity Castle wasn't Kaito's; it belonged to Nakime. With the system's conversion strengthening it somewhat, the Infinity Castle was used up as the cost of enhancement.
So...
"Haha, can it merge with the Jade Chamber?"
"Then that's perfect!"
He directly summoned the Jade Chamber.
Though it was only palm-sized in Kaito's hand, its actual size far exceeded what was depicted in the Genshin Impact game.
After merging it with his ability, let's call it the "Spatial Gate" ability for now, Kaito opened a spatial gate and walked through.
Kaito now stood before the Jade Chamber.
All it took was a snap of his fingers or a thought.
As Kaito willed it, a spatial gate opened beneath his feet and brought him to the top of the Jade Chamber.
But with another thought, he found himself inside the Jade Chamber, standing on the ceiling.
It was strange. Looking up, he saw the floor; beneath his feet was the ceiling.
Yet when he tried to jump to break this rule, he still landed back on the ceiling. Even jumping in other directions didn't work.
Even using magic to fly and stand on the actual floor made Kaito feel like he was standing on his head, his hair falling upward.
"Is that so? This aspect of the ability was strengthened?"
Initially, Kaito was puzzled. Even he couldn't break this rule?
Wasn't this even more absurd than the effects shown in the Demon Slayer manga?
It wasn't supposed to be this powerful, yet now even he couldn't break this spatial dislocation rule!
This ability had definitely reached S-Class, even SS-Class!
No...
It was because of himself!
Because his own strength was so great, after obtaining the A-Class ability and integrating with Kaito's body, it was enhanced further, reaching a level infinitely close to SS-Class!
To test if it had indeed reached S-Class, Kaito took out an S-Class Upgrade Card. Sure enough, he couldn't upgrade the ability; he would need an SS-Class Upgrade Card!
'Hehehe, that was more like it!'
The effect he could produce far exceeded what Nakime had demonstrated. There was no way it would stay at A-Class!
And this S-Class (close to SS-Class) ability was Kaito's first spatial ability.
Though it wasn't the kind that directly manipulated space, it was still a spatial ability that allowed Kaito to do many interesting things!
"It's a shame! To bring other ladies in, unless they are in the same world, it's impossible."
After exploring the Jade Chamber for an hour, thoroughly understanding the "Spatial Gate" ability, Kaito couldn't help but sigh with regret.
Perhaps it would require upgrading to SS-Class, or even SSS-Class, for that?
Of course, EX-Class couldn't be ruled out either.
What if the chat group system was so strict that it simply wouldn't allow breaking the dimensional barrier and extending the ability to other worlds?
But then again...
Now Kaito could definitely bring Kie in.
There were two conditions for using this ability.
First, he needed to know who the target was.
Second, he needed the specific location, environment, etc., of the destination. Meaning he had to have been there himself. Fuzzy memories weren't a big issue, just that he couldn't open a spatial gate precisely.
Well, it was fine. At least this time, Kaito was satisfied.
He had basically done everything he wanted to do in the Demon Slayer World.
Butterfly Mansion—
Back at the Butterfly Mansion, it was just lunchtime.
However, the first person to see Kaito return was Kanao.
Upon seeing him, she ran over nervously and took out a coin, flipping it.
She seemed to be trying to get the side that allowed her to speak.
First flip: tails. Second: tails. Third: tails.
With an expression of growing urgency, the fourth flip finally landed on heads.
At that, Kanao finally unlocked her ability to speak.
"Um... Kaito-nii, thank you for reviving my sister!!"
Even if her expression wasn't very expressive, Kaito could still hear the emotion in her voice.
"Yes, I accept your thanks. But why do you need to use a coin to decide whether to speak?"
Kaito bent down, reaching out to stroke her hair.
Kanao showed a slight sign of enjoyment, but still showed a blank expression.
After this question, she instinctively flipped the coin again, letting it decide whether she would answer.
But then...
Slap.
Kaito caught it.
"Must you rely on a coin to speak?"
Kaito asked again.
He knew this was related to Kanao's childhood trauma. She had developed a psychological condition and needed this coin to help her function.
It was Kanae who had suggested this. Thanks to her, even though she wouldn't speak when hungry, Kanao had finally started talking.
Even if conversation was still difficult, getting her to speak was a major success.
The rest would be for her to heal over time and eventually communicate smoothly with people.
But then again...
Why go through all that trouble?
This psychological condition was actually quite easy to treat!
