Byakuya's Hashirama Cells proved highly effective. Nashiro recovered quickly.
However, she'd only bitten him once and swallowed directly, without the specialized cultivation Uchiha Madara had done. Plus, Byakuya's cells were a nerfed version to begin with.
So they couldn't persist long-term in Nashiro's body.
When Byakuya returned home that evening, Nashiro was no longer in bed but sitting in the living room.
"Looks like Nashiro-san has mostly recovered?"
Byakuya asked.
"Mm. Thanks to you, Amaha-kun."
Nashiro smiled and nodded.
But then she remembered—she'd not only been at another guy's home but had lain in his bed for half a day...
The thought made her cheeks warm and flush.
"Then you two should stay here tonight."
Byakuya told Kurona and Nashiro.
"That would mean—!"
Kurona immediately thought "cohabitation" but didn't say it.
"Okay. Sorry for the imposition, Amaha-kun."
Though Nashiro felt embarrassed too, she and Kurona had no better options.
They had no money and didn't want to return to Kanou.
"No imposition. There's a spare room."
Byakuya said.
He'd clean up an empty room for the sisters temporarily.
Just like that, the household went from two to four...
...
The next day.
Kurona and Nashiro accompanied Byakuya to CCG Headquarters in Ward 1.
"Will this really be okay? Nashiro and I are ghouls now—one-eyed ghouls, sure, but still ghouls."
Kurona still worried.
"The RC detection gates will probably expose us instantly. That would implicate you too."
Nashiro added.
"Trust me. It'll be fine."
Byakuya said.
The sisters had no idea that the kakuhou Kanou transplanted into them carried a special bloodline. This involved Washuu secrets that Kanou wouldn't dare reveal.
His reassurance only slightly calmed them.
At CCG Headquarters, Kurona and Nashiro followed nervously behind Byakuya.
Approaching the RC detection gates, both sisters' hearts raced.
Anxious and with pounding hearts, they passed through the gates and... nothing happened.
Both were stunned. By all logic, they should have triggered the gates. Yet just as Byakuya said, everything was fine.
"How... how is this possible?"
Kurona whispered to Byakuya.
"It's because you're one-eyed ghouls."
Byakuya explained casually.
That wasn't actually the reason. It was because Kurona and Nashiro were one-eyed ghouls with Washuu bloodline. The RC gates had been secretly "rewritten" by the Washuus to not detect their bloodline.
But this involved forbidden Washuu secrets. Not telling the sisters was for their safety. Once they grew stronger, he could tell them.
If the Washuus discovered they knew the truth, they'd hunt the sisters relentlessly.
"I see. Nashiro and I worried for nothing."
Kurona nodded.
She simply assumed half-ghouls couldn't be detected by RC gates.
Both sisters relaxed.
Afterward, they completed their long-delayed registration. Though they received a lecture, it was a light "punishment."
Next came partnership arrangements. Byakuya confirmed the sisters didn't want to be separated.
Just as he was about to discuss this with Chairman Washuu, Special Class Investigator Kiyoko Aura found them first.
The tall woman with an alluring figure and a beauty mark near her lips was Kiyoko Aura—the CCG's only female Special Class Investigator. Her deep blue hair was tied up with a white band, giving off a cool, elegant aura.
Her attractive face appeared younger than her actual age, and those legs were stunning...
Judging by appearance, she looked mid-twenties, but she was actually thirty-six.
"Associate Special Class Ui mentioned yesterday that two exceptional twin sisters needed partners. That must be you two?"
Kiyoko Aura approached Byakuya.
"Special Class Kiyoko Aura."
Byakuya greeted her respectfully. "Yes, this is Kurona Yasuhisa, and this is Nashiro Yasuhisa."
Kurona and Nashiro also showed their respect.
"I've already cleared it with Chairman Washuu. If you're willing, you can become my partners immediately—and you won't be separated."
Kiyoko Aura addressed the sisters directly.
"I'm willing."
"Me too."
Kurona and Nashiro responded almost simultaneously.
They could stay together and partner with a Special Class Investigator. This was the best possible arrangement.
Byakuya could also relax knowing the sisters were with Kiyoko Aura.
Besides, Kurona and Nashiro already possessed S- level ghoul capabilities. The Washuu kakuhou was inherently powerful—their baseline was set.
"Byakuya, we're going with Special Class Kiyoko Aura now."
Before leaving with Kiyoko Aura, Nashiro turned to tell Byakuya.
Kurona immediately noticed Nashiro's form of address—calling him directly by his first name, "Byakuya"!
Kurona's pupils contracted sharply. She looked at Nashiro with astonishment. Had Nashiro already...?!
