For example, SS-rated Kamishiro Matasaka and SSS-rated Hoito Romathese are classic cases of being imprisoned but not executed.
Some S-rated ghouls, even if they don't hold any intelligence value, still have experimental value.
When it comes to experimentation, Kirishima Arata from the original story is a textbook case.
After he went from cannibalism and reached the level of a kakuja, he was captured alive by the CCG and used to produce a series of Quinques called "Arata." These were the armor suits initially worn by Shinohara Yukinori and Kuroiwa Iwao, which were later refined and became even more powerful.
Of course, ever since the CCG was renamed to TSC, the practice of using ghouls for live experimentation was abolished by Uchiha Byakuya.
After all, as of now they were striving for a relative peace between humans and ghouls, and such "inhumane" experiments from the ghouls' perspective naturally had to be eliminated as much as possible.
Otherwise, how would the ghoul members within the TSC feel?
On the other hand, the intelligence-value-based system remained intact because it actually worked.
Take the "Priest" as an example, it was basically a "life sentence," and they could visit him from time to time for intelligence gathering.
Although he didn't always cooperate, whenever he did, it allowed investigators to quickly crack even major cases.
"So, what should we do next?"
At this point, the young ghoul asked.
"Think of a way to lure those ghouls out. If we go looking for them ourselves, who knows how long it'll take to find them."
Byakuya replied.
"They like to target young women, right? Then..."
At this moment, Yoshimura Eto's gaze seemingly and deliberately turned toward Uruka Minami.
Feeling Eto's gaze, Minami instantly realized what was being implied. "You want me to act as bait?"
To be fair, she was indeed a good fit for the role.
First of all, she already met the requirement of being young. Then there was her appearance, she was always quite beautiful.
And because she had long coexisted with humans, her scent had also long since been muddled and no longer smelled like that of a ghoul.
"That's right. Of course, I'll be joining Minami as bait too."
Eto smiled as she spoke.
"But Eto-sensei, you're so well-known now. Wouldn't they easily recognize you?"
Minami said, a little worried.
At this point, the fact that "Takatsuki Sen" was also "the One-Eyed Owl" had already become widely known across Tokyo.
And since Eto would occasionally show up at literary events, her real appearance was no longer much of a secret either.
"It's fine. I'll just put on a disguise."
Eto replied.
As soon as she finished speaking, Byakuya very smoothly opened a "door" to the Kamui space for her.
In other words, he transferred Eto into the Kamui space, where she would be changing her outfit.
Seeing Eto suddenly disappear, Arima Kishou and Minami remained calm, they were already used to this kind of thing.
But the nearby TSC members, who had never witnessed anything like it before, were instantly shocked.
A moment later, Eto reappeared out of nowhere, and her entire look had undergone a dramatic transformation, once more, startling them all over again.
Eto had not only changed into a gothic lolita outfit, but had also styled her hair into twin tails.
It had already been several months since she last had short hair, as of right now, her hair had grown long enough to be tied up in twin tails without issue.
Aside from the unchanged hair color, Eto's appearance now looked completely different from usual, and she was also wearing a mask.
Normally, she preferred a more mature look.
"How is it? Does it look good?"
At this moment, Eto even remembered to ask Byakuya for his opinion.
"Of course it looks good. Actually, I'd say no matter what you wear, it would never look bad."
Byakuya simply told the truth.
Even if Eto were completely wrapped in bandages, the most outrageous look possible, he still wouldn't find her ugly.
Back when he first saw the image of the bandaged girl before even transmigrating, not knowing yet that her true identity was "Takatsuki Sen" and "the One-Eyed Owl," he had already found her the most captivating.
Eto let out a little chuckle.
The nearby TSC members were stunned by Eto's current appearance.
They, of course, recognized the infamous "One-Eyed Owl," so seeing her like this left them utterly shocked.
Next, the operation was about to begin.
Eto and Minami walked together down an alley where the small ghoul organization was known to appear most frequently, while both Byakuya and Arima hid in the shadows.
Once the ghouls took the bait, they would immediately strike.
At first, there was no sign of activity.
But just a few minutes later, there was finally some progress.
Several masked ghouls began emerging from all directions, blocking Eto and Minami's path.
At that moment, both Eto and Minami were acting very convincingly with fright and fear being written all over their faces.
"You… you're ghouls?"
Minami feigned a step backward, her tone panicked as she asked.
"Do you even need to ask that, little lady? Even if you've never met one before, you've surely seen ghouls on TV, right?"
One of the ghouls replied with a mocking tone.
It was as if Eto and Rika were already food on a platter to them, and they were in no hurry to make a move.
Eto immediately grabbed Rika and turned to run, only to find several more ghouls blocking their escape.
"How amusing. Didn't those TSC folks already issue a warning in the 22nd Ward? And yet you two girls still dare wander around dangerous places like this. Don't tell me… you're from the TSC?"
"Even if you are, who cares. The TSC folks in the 22nd Ward are all useless. They're no threat to us. We've got a boss."
"Yeah, our boss is a half-kakuja. Once he gets serious, no one in the 22nd Ward can take him."
"..."
The ghouls started chatting among themselves, clearly not taking Eto and Rika seriously.
And up until now, Byakuya and Arima still hadn't made a move.
