Sharing Bodily Fluids
I am Lee Shin.
Twenty-two years old.
A damn healthy adult male. Discharged from the military.
And right now, I am doubting my own eyes.
Roar!
Calm down, Magnum! You mustn't run wild!
Whimper...
First, I calmed down my lower half, which was acting up on its own. As expected of the Marine Corps method for suppressing an erection.
Currently, a woman dressed in a damn aggressive outfit is smiling right in front of me.
We aren't in ancient Greece, so how can she walk around wearing something like that?
Ah.
She's a cosplayer, isn't she?
She must be working part-time at this Management Bureau attraction!
Cosplayer Lael. I won't forget this.
What a truly moving figure. The greatness of the female body naturally inspires a sense of religious devotion.
As I nodded to myself, Lael giggled.
"Wow. You're huge. Is that all muscle?"
"Damn right."
"I like it. Can I hug you?"
"Of course."
Living a good life pays off. Shall we share some body heat with a full-body embrace?
There is absolutely no ulterior motive!
Unfortunately, Tatiana chimed in.
"SIN-077. Please cease any erratic behavior. I would appreciate it if you sat in the containment chamber chair."
"Aw, why?! ...Fine. I'm only doing this because you asked."
Lael crossed her arms and obediently backed away.
Slide.
The way she crossed her legs was quite... something.
"But where's my food?"
"I brought it."
"...You guys didn't forget, did you? If I don't drink blood, it's a containment breach. I can't control it. I don't want to kill innocent people either."
"We are well aware."
"But I don't see any blood packs. Isn't that just a water bottle?"
Lael fidgeted anxiously. She looked at the timer on the wall and grew increasingly restless.
"No, wait. There are only ten minutes left. You in the front with the gas mask, you're Tatiana, right? What are you thinking?"
Oho. Is their backstory that they already know each other?
Tatiana replied calmly.
"SIN-077. We have decided to make today's blood supply much fresher."
And then, she pointed at me.
"......Huh? Are you guys crazy? You want me to drink from him? Alive?"
"Yes."
"No, no. He'll die then."
"He won't die."
"Are you seriously joking? Now you're giving me a live human? Is this really the Management Bureau?"
Lael grimaced in disgust, her face filled with contempt.
Though, I hadn't actually heard anything about this beforehand.
"Hey, Tatiana. Is that woman going to drink my blood?"
"Yes. It's not a setup; she is actually going to suck your blood."
Straight to the point. Well, whatever.
Let's run a quick simulation in my head.
Lael climbs on top of me, wets my neck with her saliva, sinks her teeth in, and sensually sucks my blood?
Oh.
Fuckable.
This is a damn reward.
I grabbed a nearby chair and sat down.
"Drink it right now! My fresh blood!"
"Um, are you out of your mind?"
Lael looked at the timer and let out a sigh.
"...Fine. I guess it's better than hundreds of thousands of people dying. Hey, I'll apologize in advance. I'm sorry."
As I stared blankly at her, Lael twirled a strand of her hair.
"Because you'll probably die while I'm draining you."
This woman is even kind?
If you're pretty and kind, you're usually innocent. At least, that's what they taught in the middle school curriculum.
"Come at me."
"...Okay."
Lael climbed onto my lap. She grabbed my shoulders and slowly brought her face close.
"What's your name?"
"Lee Shin."
"...I'll remember it."
As her hair brushed against the tip of my nose, a pleasant scent wafted over. It carried a faint trace of blood.
Gasp.
I heard her take a deep breath.
"Ahm."
Crunch!
Her teeth pierced straight into my neck.
Drinking fresh blood was not a common occurrence.
Humans were fragile creatures; they died if you so much as nudged them.
This was a truth Lael had realized from the very moment she drew her first breath, a long, long time ago.
She did not know why she was born with such immense power. She only felt an endless, bottomless thirst.
Perhaps it was because of her winged appearance, but humans worshipped her, calling her an angel.
Thanks to that, she had plenty of opportunities to drink human blood. Even so, she took no pleasure in killing them.
It's not like I'm a vampire.
She refused to become like those disgusting creatures that crawled through the night.
She had rightfully purchased the right to drink blood through barter.
Yet, humans died far too easily.
If she drank too quickly, they died of shock.
If she drank too much, they died of excessive bleeding.
But if she just drained them indiscriminately, how would she be any different from a vampire?
Even after building a flourishing civilization alongside humans and standing at their peak, Lael's thirst persisted.
Then... should I try to endure it a little, as the oracle said? Just until I get too thirsty. Because I don't want to become a monster.
Lael did not touch a single drop of blood for a whole day.
That day, an entire human civilization was drenched in blood.
Huh...?
By the time she snapped out of it, mountains of shriveled corpses had piled up. Every single one of them looked like pale stone, completely drained of blood.
Lael looked at her reflection in a pool of blood.
There was no angel.
Only a blood-sucking vampire remained.
It was deeply, deeply unpleasant and disgusting.
That was her first containment breach, thousands of years ago.
Gulp. Gulp.
Maybe it's because I'm drinking a live human's blood for the first time in a while. I'm remembering useless things.
Returning to the present.
Lael was currently sucking the blood of a sturdy human male.
She was focusing all her nerves on not drinking too quickly or too much.
"Mmh. Are you okay?"
"Yeah. It feels pretty damn good to be sucked."
Blood Supplied: 1L
It was getting dangerous. Normally, humans would lose consciousness after losing this much blood.
But I still feel the thirst.
If she stopped now, a containment breach would occur. This bottomless thirst was not something Lael could control.
Do something...
Lael cast a pleading look at the Containment Task Force.
Yet, Tatiana only gave a bizarre, nonsensical order.
"Supply water to SIN-998."
"Oh. I was just getting thirsty."
Gulp, gulp.
The giant of a man who introduced himself as Lee Shin drank the water. Meanwhile, Lael was drinking his blood.
What kind of situation is this?
Did all these humans undergo some collective common sense alteration?
Her confusion quickly turned into sheer astonishment.
Blood Supplied: 6.7L
How?
This made absolutely no sense.
He's... converting water into blood in real-time?
It was an anomaly she had never heard of or seen before.
Actually, she might have heard of something similar. Lael had lived for a very long time, after all.
It was the story of the man on the cross.
— No wine? Just you wait.
— Lord, this is water.
— Uh-uh. Drink up.
— Gulp, gulp. Oh my... my legs feel like jelly...
The miracle of turning water into wine.
It was similar. Or was it? It was hard to say.
Lael looked up at Lee Shin with concern.
"Aren't you dizzy?"
"Nope."
"...If you drink that much water, won't you die of water intoxication?"
"Haha! You're hilarious. How can anyone get poisoned by water?!"
"...You're an idiot."
Middle school dropout.
Before these three glorious words, common sense was utterly meaningless.
Lee Shin wrapped his arm around Lael's back and whispered.
"Your sucking is pretty weak. Are you holding back for my sake?"
"Mmh? I guess so."
"Don't worry about it. Drink as much as you want."
"...Really?"
She didn't need to worry about him dying?
Just this once.
Should she trust him just this once?
Gulp. Gulp.
Only then could she truly savor the taste of the blood.
A faint saltiness bled through the metallic tang, and a certain refreshing sensation accompanied each swallow. The pressure at which the blood gushed out was also perfectly brisk, almost like...
Beer!
This is delicious.
It was the highest quality of blood she had ever tasted in her entire life.
After drinking for quite a while, her face flushed warm. Lael finally wiped away the blood trickling down her chin.
Blood Supply Method: Direct Supply
Designated Volume Supply Complete
Behind them, Tatiana spoke.
"Command and Control. Verify containment status."
"SIN-077 is successfully contained. Return to base."
They had prevented a containment breach.
Only then did the Containment Task Force breathe a sigh of relief.
Lael also exhaled a warm breath, leaning against Lee Shin.
"...Phew."
"All done?"
"Yeah. It was delicious. Extremely."
Come to think of it, since she had such a satisfying meal, she should probably treat him with a bit more politeness, right?
Lael wiped the blood from her lips and smiled alluringly.

"Thank you for the meal. Fufu."
The phrasing was a bit... something, but whatever.
If possible, she wanted to drink from him regularly... but that would be greedy. She had to restrain herself.
However, human thoughts are usually quite similar.
Tatiana exchanged a few words with Command and Control, then nodded.
"Vitals are perfectly normal. 998, are you feeling dizzy?"
"Not at all. Want me to show you a hundred burpees?"
"No, that's quite enough. ...998. If you are fine with it, we plan to have you supply blood to SIN-077 like this on a regular basis."
Oh?
At those words, both Lael and Lee Shin turned their heads.
"Really?"
"That's a fucking reward. I'm down."
From the Management Bureau's perspective, it was a win-win since they wouldn't have to bust their asses trying to procure rare blood.
Just before the containment chamber door closed, Lael's eyes curved into crescent moons.
"See you again. I'll be waiting."
"Next time, I'll prepare a straw."
The blast door shut.
Lee Shin, was it?
A strength that kept him alive no matter how much blood was drained. A boldness that didn't even blink. A highly masculine, muscular body.
Even his subtle lack of common sense.
She liked him quite a lot.
Time Until Next Blood Supply:
23 hours 57 minutes 06 seconds
Serial Number: SIN-077
Alias: Lael
Danger Rating: Beta
SIN-077 is an entity revered and feared as a monster in the mythology of the [DATA EXPUNGED] pantheon.
Records of her activity date back to approximately 2000 BC, with numerous stone inscriptions and engravings discovered in the Greek cultural sphere. To conceal this information from the public, the Management Bureau's Covert Operations Division disseminated the false name '■■■'. For her relationship with the Mycenaean civilization, refer to [SIN-077 / Age of Myth].
If SIN-077 fails to consume human blood within a 24-hour period, a Grade 3 wide-area thaumaturgical disaster will occur. For related disaster records, refer to [SIN-077 / Containment Breach Log].
The rarer the blood type, the lower the required intake volume. Direct consumption reduces the required amount by approximately 99% (to 1% of the standard volume).
[REVISED CONTAINMENT PROCEDURES]
Direct blood supply was successfully executed by utilizing the anomalous nature of SIN-998 <Director>. An increase in SIN-077's psychological stability has been observed.
The revised containment procedures are as follows:
1) Attempt direct blood supply utilizing SIN-998.
2) If step 1 cannot be performed, supply reserve blood packs.
* Please, do NOT, under any circumstances, tell SIN-998 how human blood is actually made.
— Bishop Miriam, Department of Religious Theology, Management Bureau Headquarters
* I'm thinking of raising my daughter to be a middle school dropout.
— Anonymous
Late at night, after returning SIN-998 to his containment cell.
High-ranking staff from the relevant departments gathered once again in the mid-level conference room. The Site Overseer was also present.
"A groundbreaking anomaly. If not for SIN-998, we would be recovering the shriveled corpses of hundreds of thousands of citizens right now."
"Or we would be dealing with a rampaging SIN-077."
For the first time in a long while, the Site Overseer was in an exceptionally good mood.
They had managed to prevent a containment breach. Furthermore, the Management Bureau Council seemed to be quite interested in this case.
The favor of the higher-ups was crucial.
No matter how extrajudicial the Management Bureau was, they ultimately could not ignore political gains and losses.
Thus, the Site Overseer nodded with satisfaction.
"I hear SIN-998, the , has a request?"
"Yes. He wants the orphanage children to reside inside the site."
"Grant his request. There must be a reward. ...Sunshine Orphanage, was it?"
A nice name.
Right now, the Human Resources Support team staff should be taking care of the orphanage children.
"Contact the staff out on the field and tell them to bring the children here."
"Yes, sir!"
Yoo Seohah quickly pulled out her phone. However, for some reason, her expression began to darken.
"Uh. Uh...??"
"Assistant Researcher?"
Yoo Seohah shrieked in panic.
"The kids escaped! They got on Line 1!!"
The staff gathered in the conference room instantly broke into a clamor. Tatiana and the Site Overseer both pressed their hands to their foreheads.
Metropolitan Subway Line 1...
A Gamma-class regional anomaly!
SIN-666, !
The bastard who has no legs but stands up at the terminal station.
The Steel Flute Bridal Mask Murderer.
Great King Nirvan the 4784th.
The horny, carnivorous woman from the twisted nether (114kg).
The subway line drilled all the way to the bottom of hell, and so on.
It was an anomaly born from the urban legends of the human subconscious, the nightmare of the metropolitan citizens.
Current time: 00:41 AM. The last train of the normal line should have stopped running long ago.
Naturally, what the children boarded was the anomaly.
"What kind of anomalous properties manifest at this hour?"
"It's likely a spatial anomaly. Pull up the route map. It might lead to another world, like Sanctuary Island..."
"No, but the orphanage kids are missing, right? And we have to tell the Orphanage Director about this."
Silence instantly descended upon the conference room.
Someone carefully opened their mouth.
"Who is going to tell SIN-998?"
