Sorry, you scumbag woman, you can do whatever you want.

He desperately resisted Mebius's examination of his body.

"Don't move around, cooperate with the doctor." Möbius frowned in displeasure, but this only resulted in Theresa resisting even more fiercely.

"I'm fine, not there... don't touch me!" A shy, girlish voice echoed in the ward as the vampire girl pressed her hand against Mebius's cheek. "Doctor, how can you do this? I'll never get married if you keep doing this!"

“I will take responsibility,” Möbius replied confidently, but Theresa responded with a fierce look.

"I'm a vampire, if you keep doing that I'll bite you!"

"Are you a puppy, trying to bite?" Mebius looked at Theresa's two small, sharp teeth and regretfully withdrew his hand.

"It's all because you touched me!" Theresa retorted, raising her voice as she carefully straightened her clothes, which Möbius had messed up.

A moment later, she looked up at Mebius and spoke.

"Human, you are strange."

“Strange, is this your impression of me?” Möbius nodded knowingly. “Then I’ll give you an equal answer.”

She spoke under Theresa's crimson gaze.

"A vampire girl full of mystery and the unknown is really intriguing and makes me want to explore further."

Can I get to know you better?

stunned.

Theresa had never heard such strange words before. Her crimson eyes were filled with confusion, and she didn't know how to respond.

The canary in the cage is far too innocent.

Chapter Four

Naive girls are so easy to fool.

silence.

silence.

silence.

"..." Theresa's delicate face revealed distress, as if she was thinking about how to politely refuse.

However, this was quite difficult for her, who had always been a caged canary, as most of her knowledge came from books.

There are many things I haven't experienced.

However, this is only natural, as she is a tool for maintaining the existence of "Kallen" to her creator, 'Otto, Apocalypse'.

By sucking blood, bacteria-shaped Honkai Beasts are injected into the user's body, transforming the recipient into a half-human, half-Honkai Beast state.

This is almost identical to the legendary vampire tales, but there are some differences. In A-872, that is, in this world, Theresa can infect not only the living, but also the dead.

And then everything proceeded in a logical manner: Otto made Theresa of this world drink the blood of Kallen, a saint who had been dead for five hundred years.

The saint Karen, who died five hundred years ago, was resurrected.

However, this resurrection... cannot last forever, if one day "Theresa" dies.

The resurrected Kallen will also die.

Therefore, in order to ensure the safety of his saintess, Otto kept Theresa locked up in the Destiny Palace like a canary.

They are not allowed to go out, nor are they allowed to have too much contact with people.

"I'm sorry, I refuse," she said after a moment's thought, shaking her head firmly. Although the green-haired girl showed no malice, but rather goodwill, it was precisely because of this that she could not get close to her.

Anyone who gets close to her... will be hurt.

Moreover, she didn't have much time; she had to take advantage of any free time to fulfill her wishes.

I want to see the world.

"That's a real shame. I was hoping to help you cure your vampire urges." Mebius sighed as if disappointed, but his eyes revealed a mischievous smile as he stared at the astonished vampire girl.

"In this world, I may be one of the few people who have the opportunity to completely cure you."

"...The urge to drink blood is not a disease." Theresa's scarlet eyes revealed sadness as she gently shook her head. She knew her body very well; it was a part of her that she was born with, as natural as breathing.

If it's not an illness, then naturally it cannot be cured.

"Then do you know where the blood-sucking urge comes from?" Mebius asked calmly, leaving Theresa stunned. It was like asking someone why they breathe.

"...I don't know." Surprisingly honest, Theresa shook her head gently. She had never thought about where her innate blood-sucking urge came from, just like the ancients who didn't think about why the apple fell.

That's a very natural thing.

“It’s the malice of the Herrschers from the previous civilization,” Mebius answered with a light laugh. “If Miss Vampire can obtain the Key of Corruption, then in a sense, she will be equivalent to the legendary Herrscher of Corruption.”

She asked Theresa.

"So, do you now know where your malice comes from?"

"..." Theresa lowered her head, looking at her slender, fair hands. "The source of this malice is that the Herrscher of Corruption wants to destroy humanity?"

She knew about Herrschers, and she was also aware that she had borrowed the power of the Key of Corruption to be born.

However, he never imagined that the source of his blood-sucking urge was the Herrscher of Corruption from 50,000 years ago.

It was unexpected, yet it felt perfectly reasonable.

“If that’s really the case, then killing me is the best option.” Theresa tilted her head slightly, looking at the smiling green-haired girl opposite her, her tone almost resigned, “But before I die, I have a request…”

Before she could finish speaking, Mebius pressed his finger to her lips, revealing a playful yet mocking smile.

"The malice of a mere Herrscher is utterly insignificant compared to the malice of a human." Mebius sat sideways on the edge of the bed, watching the duck sitting on the bed with a somber expression, while Theresa smiled faintly, as if she had given up completely.

"Moreover, the Herrscher's malice that you inherited is not all of it; there is also a part that belongs to 'you'."

“...Is that so?” Theresa’s empty eyes seemed to light up slightly as she asked Mebius.

"Why do you know me so well?"

In this world, not many people know her, let alone understand her existence. However, the green-haired girl in front of her understands her existence better than she does, as if she has known her for a long time.

She and this unfamiliar girl were meeting for the first time.

Moreover, he was being far too intimate with her.

"Wait, let me think about how to make this up." Möbius looked thoughtful, glanced at Theresa's slightly puffed-up cheeks, and then couldn't help but chuckle.

"I'm not teasing you anymore, I'll tell you the truth." She gazed at Theresa's delicate and pretty face. "Actually, this isn't the first time we've met. I've known you for a long time, but you just don't remember me."

"Have you seen me in Destiny?" Theresa wondered. She had always existed in Destiny and had never met any outsiders. Could it be that this girl in front of her had met her by chance in Destiny?

Or perhaps it was the researchers of Destiny who specifically studied her data and intelligence, which is why they were able to say that they could cure her.

“Well, you could say that.” Möbius nodded slightly, offering no further explanation, but simply smiled at Theresa and said, “So, will you try to cooperate with my treatment?”

It's not an empty promise; she genuinely wants to heal and understand Theresa's existence. This isn't just an act of pure goodwill; she also wants to learn about Honkai, Herrschers, Fusion Warriors, and other related information by studying Theresa.

If she can gain something, she will be able to prepare in advance for returning to the previous civilization, and the probability of crossing the end will be greatly increased.

Therefore, she really wanted to understand Theresa, and even more so, to understand Theresa's body in depth.

It would be best to reach the depths of Theresa's soul.

"Did Grandpa send you to treat me?" Theresa asked curiously, though she already knew the answer in her heart.

This must be her grandfather, Otto… the researcher who sent this green-haired girl to treat her vampire urges.

but.

“No, this is my own will.” Möbius shook his head. “Wanting to save you was my own decision.”

At this point, she gave Theresa a gentle smile.

"Letting a beautiful young girl die is something no one could bear, at least... I couldn't bear it for you."

"Is...that so?" Theresa turned her head slightly, her delicate cheeks flushed slightly, and said almost imperceptibly, "Thank you."

They actually believed it; they're so easily fooled.

Möbius's smile softened, and he continued his friendly conversation with Theresa, exchanging names with her.

And some trivial matters.

And at the same time.

Outside the ward, Himeko and Karen stood facing each other by the door, neither choosing to enter and disturb the other.

At least, before confirming Möbius's identity, there was no intention to go in and disturb him, in case Möbius really was a researcher sent by Otto.

If they could actually cure Theresa's vampiric urges, then they wouldn't need to kill her.

This is naturally the best outcome.

“…I’ll go contact Bishop Otto.” Kallen whispered to Himeko beside her, then silently left the ward.

A moment later, in the hospital corridor.

Karen gazed at the night sky, her expression relaxing. She had received a definitive answer from Otto: the woman known as Mebius was the doctor he had sent specifically to treat "Theresa" in order to resolve her vampiric urges.

He's not some guy with ulterior motives.
