This mission had too much suspense...
Originally, it was just to understand Tony's physical condition and, by the way, find out what kind of person Dr. Tamayo was—the one Quinn had brought Tony to see.
After all, neither Quinn nor Tony were ordinary people.
The person who could make them introduce and arrange a meeting would most likely not be ordinary either.
As a result, despite having the approximate location of her residence, he couldn't even find the address.
This made him even more certain she wasn't an ordinary person.
Coulson had gone to Quinn for help.
As a result, Quinn had directly given him a list of suspected dimensional travelers.
And this time, Dr. Tamayo and her assistant whom he was going to meet were on this list, which changed his purpose from 'finding out details about them as a secondary objective' to 'making it the primary objective.'
During the subsequent investigation, he'd learned about Blood Demon Art, the Twelve Kizuki, and an existence that made demons feel fear just from mentioning their name.
This was very bad news.
In the beginning, when he'd learned about man-eating demons from Quinn, both he and Fury had been somewhat dismissive.
After all, this was a world dominated by humans, and the powerful vampire empire had to sign various agreements with humans and live in the shadows by following human rules.
And although these demons had physiques and abilities surpassing humans, they were still too small compared to entire human society.
For them to make trouble with such fanfare was undoubtedly self-destructive.
Therefore, when Coulson and Fury had learned about demons, they'd subconsciously regarded them as stupid and arrogant creatures with great power.
But the information he'd learned now was different from what he'd imagined. The other side had a very rigorous organization and possessed Blood Demon Art on top of the basic strength all demons had. Their power was beyond imagination.
Maybe it wasn't because of stupidity or arrogance, but because of fearlessness.
He hadn't known before, or it had been difficult to ask because of his position.
But now that he'd been transformed into a demon, these things were closely related to him, and he also needed to know the truth.
"...You do have the right to know the truth about your identity and situation. Then, Mr. Coulson, let me tell you a story first!"
Hearing Coulson's request, Tamayo said calmly after a moment of silence.
Then she told Coulson and Bobbi the story of Muzan Kibutsuji, and through him led into the Twelve Kizuki and the grudge with the Demon Slayer Corps, allowing them to basically understand the backstory and setting of demon slaying.
"..."
After listening to the story, both Coulson and Bobbi fell into silence, recalling everything Tamayo had said.
The Demon King Muzan transformed from a human, the Twelve Kizuki, the Demon Slayer Corps that hunted demons... All of this was too mysterious and bizarre.
If it had been in the past, they would have sneered when hearing such a story, thinking it was nonsense.
After all, a doctor a thousand years ago using medicine to create a Demon King? This wasn't as reliable as it being born by accident.
But now, having seen the power of demons with their own eyes and been transformed into demons themselves, they had to believe it.
Coulson took a deep breath and looked at Tamayo with a serious expression. "Two last questions."
"Please ask. If I can answer, I'll tell you everything."
"Miss Tamayo, Mr. Yushiro, and even that Muzan Kibutsuji and the demons under him are all Japanese, so why did you come to New York?" Coulson stared into Tamayo's eyes and continued asking. "You're not people of this world, are you?"
"Yes, we're indeed not from this world."
Contrary to Coulson's expectations, Tamayo didn't hesitate or lie on this issue but admitted it openly.
She seemed to see that Coulson was puzzled, shook her head slightly, and explained. "If your organization is really a United Nations organization dedicated to maintaining world peace, then with your resources, you'll be able to easily discover that 'we have no past in this world,' so there's no point in hiding it."
"That's right. Miss Tamayo is truly a wise person!"
Coulson suddenly understood, then sincerely praised her.
Whether it was her performance in the previous battle or her judgment in the current conversation, she was worthy of this compliment.
Tamayo shook her head lightly, not commenting on this.
"Then does Miss Tamayo know why you crossed over?" Coulson continued asking.
"Is this the last question?"
"Uh... It's a derivative of the first question!"
"Cunning guy."
Yushiro gave him a sideways glance, then turned his head away, seeming to disdain looking at him.
Coulson didn't care, maintaining the same smile on his face.
"I don't know." Tamayo shook her head gently. "There was no sign before crossing over. I just opened the door to go outside, but as soon as I stepped out, I came to this world. When I looked back, the gate and the house had disappeared."
"I saw Lady Tamayo disappear after going out, so I chased after her. But as soon as I went out, I crossed over too."
Yushiro said, paused, and continued. "Although I followed, I came to this world a day later than Lady Tamayo, and the crossing location was different."
There's a slight difference from the Vongola Family's crossing situation.
Coulson pondered slightly and continued asking. "...Was there anything special about the door you passed through?"
"It was just an ordinary wooden door. We went in and out every day, and there had never been an abnormality before."
"Well, then the last question..."
Coulson heard this and knew he couldn't learn more, so he asked the final question. "What is the relationship between Miss Tamayo and Mr. Quinn, or what kind of person is Mr. Quinn?"
Coulson said, watching Tamayo's expression closely, and continued. "Both Mr. Stark and I were introduced by Mr. Quinn, and Mr. Yushiro's words earlier were also full of respect for Mr. Quinn. What is your relationship?
Also, you mentioned earlier that members of the Demon Slayer Corps rely on breathing techniques to fight demons.
And Quinn once used a technique like Sun Breathing. Is he a member of the Demon Slayer Corps from your world?"
"You bastard..."
"Yushiro!"
Tamayo raised her hand to stop her assistant who was about to scold, but the light in her eyes lost the gentleness of the past and became cold.
"Mr. Quinn has been kind to me. I shouldn't disclose his information to others..."
Tamayo said, taking a deep breath, and continued. "But I don't know much, and it's all irrelevant things. Mr. Quinn also said that if someone comes to investigate him, I can hand over the information for my own safety. So I'll let you know.
I don't know who Mr. Quinn is or why he knows breathing techniques. We met in this world.
When I first came to this world, I had no understanding of the current situation.
Mr. Quinn found me, told me about the current circumstances, and gave me a sum of money so I could settle down in this world.
After that, when Yushiro came, he helped find him too.
We've received his great favor!"
