After temporarily settling down at the Butterfly Mansion, they were not in a hurry to go to headquarters. Shinobu still needed to confirm if this demon truly had some real capabilities.
Tamayo faced such suspicion without anger or annoyance; it was normal. The Ubuyashiki family had hidden for so long without being found by Kibutsuji Muzan, so without some vigilance, they would have been wiped out long ago, let alone allowing her, a demon, to approach.
She handed a thick stack of notebooks to Shinobu. These contained all the experimental details and conclusions from her long-term research on Yoizumi's and Nezuko's blood.
"These are my research findings. Miss Kochou can take a look first."
After taking them, Shinobu sat down and began to read through them carefully.
The human and the demon began their work without much conversation. Tamayo looked at the various precise instruments, large and small, in the room, many of which were unobtainable even with money. Tamayo couldn't help but marvel at the Ubuyashiki family's extensive connections.
Yushiro, unable to help, could only pace back and forth in the room, restless and uneasy. He bit his thumbnail, his face grim. He found it hard to relax in such a dangerous place.
And that woman!
She looked so wicked. Would Lady Tamayo be bullied?
Yushiro grew even more anxious.
Tamayo quietly waited for Shinobu to examine the notes, her gaze falling on the slender girl. She recalled what Yoizumi had mentioned in his letter: this girl's body contained a large amount of poison.
After Tamayo's rough examination, just by observing some details of her body, she had already confirmed, "It's more than just a large amount of poison, Mr. Yoizumi."
"It's a lethal dose!"
Even now, Tamayo couldn't help but admire the young girl before her. To have such deadly poison in her body and remain so composed, she even respected her courage to inject it.
"You've truly given me a challenge, Mr. Yoizumi."
However, since she had agreed, Tamayo would try. As a doctor, when faced with an extremely challenging illness, there was no reason not to take on the challenge.
Her finger traced the words on the page. While Shinobu read intently, she could still feel Tamayo's gaze on her. Without malice, she didn't pay it much mind.
Because of Yoizumi and Nezuko's existence, her aversion to friendly demons wasn't too strong, provided the other party hadn't eaten humans.
It's just... the content here. It seems this demoness has drawn quite a bit of blood from her Yoizumi... Tamayo suddenly felt the anger emanating from Shinobu. Before she could wonder what had happened, the anger vanished without a trace.
Because Shinobu herself remembered.
When she first met Yoizumi, she had also drawn a lot of his blood. She herself had no right to criticize Tamayo... Moreover, this research contained much that she hadn't discovered, with great value for deeper investigation.
Putting down the material, Shinobu had to admit, this was a demon worthy of respect and learning from.
"I've finished, Miss Tamayo. You are very impressive. I think we will cooperate very happily~" Shinobu made no attempt to hide her thoughts, extending her hand towards Tamayo.
Tamayo's hand rested in Shinobu's palm. "Pleasure working with you."
When Tamayo tried to withdraw her hand, she found she couldn't. She looked up at Shinobu, who still wore the same gentle smile as before, but her eyes were dark, and her voice carried a tone of certainty.
"Miss Tamayo, you've eaten humans, haven't you?"
..."What are they saying? Damn it, I can't hear clearly at all." Yushiro was crouched by the door, his ear pressed against it, eavesdropping.
He absolutely wasn't trying to do anything, just being cautious!
"Hey hey~ Kiyo, what's that man doing?" Saho asked, tugging on Kiyo's sleeve, puzzled.
"I don't know either, he's a strange person." Kiyo watched Yushiro's peculiar behavior, hesitating whether to go say hello. Lady Shinobu had told them earlier that two special guests would be arriving.
"That..."
"Hm?!" Yushiro suddenly turned his head to look at the two little girls, his face scowling, his tone not very pleasant, successfully scaring them both.
"Nothing at all!" Kiyo pulled Saho and ran off.
Pressing his ear to the door again, Yushiro tried to concentrate on hearing the commotion inside. "Damn it, I was interrupted. I wonder if I missed anything important!"
Inside the room, Shinobu's voice happened to drift into his ears.
"Miss Tamayo, you've eaten humans, haven't you?"
!!!
He knew this woman had ill intentions!
He himself wouldn't even dare to ask that question!
Pushing the door open forcefully, Yushiro glared fiercely at Shinobu, his tone vicious. "What do you wicked woman intend to do to Lady Tamayo?!"
Yushiro sensed Shinobu's hatred for Lady Tamayo, and Shinobu likewise sensed Yushiro's killing intent towards her.
The human and the demon confronted each other. Tamayo, on the side, also had an unpleasant expression, as she was reminded of her past, a past she was unwilling to revisit.
She knew Yushiro was thinking of her. Her light purple eyes dimmed as she lowered her lashes, and her hands, clasped in front of her chest, tightened slightly, as if she had made a decision.
For revenge, to avenge that damned beast, she was willing to be honest about her past.
Walking over to stand beside the two, she patted Yushiro's shoulder and said softly, "Yushiro, I'm fine. Don't be so reckless next time."
"Lady Tamayo..." Yushiro looked at Tamayo worriedly.
"I have something important to say to Miss Kochou, so Yushiro, please step out for now." Tamayo smiled at him, signaling that she was fine, and Yushiro slowly shuffled out of the room, looking back three times.
Turning to Shinobu again, Tamayo nodded, her gentle face filled with sorrow and pain.
"Yes, I have eaten humans..."
She actually admitted it... Shinobu thought, somewhat surprised.
