Act Zero: An Unremarkable Daily Life

“I… want to be your slave.”

“Big brother~~”

The night was cool and still.

Beneath the moonlight, the girl wore a thin veil. Silky silver hair fell to her waist, and her delicate cheeks were flushed crimson. Her eyes were hazy, her soft pink lips slightly parted as she leaned close to my face, breathing warm, sweet air against me…

I stood there with my jaw hanging open, completely dumbfounded.

What was going on…?

Oh, right…

I’m Ojer, a skeleton. Bone age: twenty-two.

Current status: being… pushed down by my own little sister…

…in progress.

W-w-w-whaaat?!

……

…

“Hey, big brother…”

The girl climbed onto me. Her slender fingers traced each of my ribs, teasing them playfully. Her soft, boneless body rubbed against my breastbone, then she lowered her head beside my ear and whispered in a gentle, tender voice.

“If it’s you, big brother, I don’t mind~”

Me: “……”

After saying that, she straightened up and breathed out a sweet sigh. Her pale, flawless legs clamped around my pelvis, and flirtatious pink glimmers danced in her misty eyes.

She gazed at me with deep affection, and then…

licked her lips seductively.

Thump!

I felt my nonexistent heart give a little twitch.

Oh no! This is what a heart flutter feels like!

“Eileen, Eileen, get down first…”

I had to admit, Eileen looked incredibly alluring as she licked her lips. She was more captivating than any girl I’d ever seen. But considering her age and that youthful face, the combination gave off an indescribably forbidden air.

But she was my little sister!

So why had things turned out like this?!

“Aww, but I…”

My little sister was still straddling my waist when she suddenly froze. A “glug” came from her throat—

“Hic~”

She let out a dazed little drunk hiccup.

“Huh?”

Why did I smell alcohol?

“Ah… there you are…” “!!”

A small, startled voice came from the doorway. I whipped my head around so hard I nearly snapped my neck. A vampire girl in a white lab coat was staring at us, looking like she wanted to curl up into a ball. Her long, pointed ears drooped, and her face was full of awkward embarrassment.

“Aili, what have you made this time?!”

“Mmm…”

She scratched her cheek and gave an embarrassed little smile.

“It’s a low-alcohol fruit wine with an aphrodisiac effect. I think she drank it thinking it was juice…”

“The whole bottle…”

Me: “……”

“Big brother~~~”

“Gaaah—!”

I was just about to say something when my sister grabbed my head and wrenched it back. My spine gave a sharp crack, like it had snapped clean in two.

I can’t feel my body…!! My neck really snapped!

“Don’t look at other girls. Didn’t you say you wanted to stay with me forever~~~?”

When I realized my body was no longer under my control, I panicked and shouted, “Aili… Aili, help me!”

“Ah…”

But the girl I called out to looked up at the ceiling, clasped her little hands behind her back, and smiled innocently, pretending it had nothing to do with her.

“Um, well, I’ve got research to do on the railgun—and, oh right, research on the Undead Tank’s stability. Bye!”

“Hey! Don’t go!”

But it was too late. She’d already darted off.

“Eileen… get off me first…”

“Nooo, I want to do fun things with big brother!”

“Skeletons can’t do that!!” I yelled in despair.

Eileen pouted unhappily. She was just about to say something else when—

“Yoo-hoo, Ojer!”

“Huh?”

Another energetic girl appeared, dragon horns growing from her head.

“Hey… wait…”

She ran toward me.

“Guleiya! Don’t come over here!”

She jumped!

And then—

“Gah—!”

I felt a violent impact. My frail spine and breastbone let out a shrill cry, followed by the crisp sound of my ribs breaking.

I shattered.

“Ah… the bones broke…” The dragon girl called Guleiya held two broken ribs in her hand, swished her big tail, and tilted her head as she inspected them.

Then she tossed them away like trash.

“Hey, those are my bones! Why’d you throw them away?!”

“Don’t worry about that! More importantly, hey, I’m hungry again! Make me something tasty!”

“Didn’t you just eat? Where’s Lancelot? Go ask him to cook for you!”

I felt like I was about to crack apart.

Both physically and mentally.

“He went out to look for something. Hey! I want that guobaorou we had last time!”

But Eileen wasn’t having it. She leaned over and whispered something in Guleiya’s ear.

“Oh, oh… I see… That would work… Let’s split him between us…”

Guleiya looked at me with a thoughtful smile.

A chill ran down my spine.

“…What are you two talking about?”

But the next moment—

Burp~

“Hiyah!!”

“W-w-w-whaaat?!”

Eileen yanked my head right off and hugged it to her chest like a precious treasure. She looked at me with a somewhat deranged smile, her gaze growing emptier by the second.

“Hehe… now we can be together forever, big brother~”

“Wait, Eileen, your expression is getting weirder and weirder! And Guleiya! Put my body down! Where are you taking it over your shoulder?!”

I called out to the girl carrying my headless skeleton over her shoulder, but she answered me with an innocent look.

“To the kitchen. Ojer, you can still move even without your head, right? Then Eileen and I will split you up. Your body’s mine!”

“Hehe, then big brother’s head is mine~~”

“Hey! Don’t go!”

But it was too late again.

She bounced out of the room with my body over her shoulder.

What on earth was happening today?!

“My lord? I saw Fourth Miss. She seemed to be… Ah…”

Another person… no, another skeleton came in. He wore a dark robe, and two crimson ghost fires flickered beneath the black veil over his face.

But when he saw Eileen, completely naked and rubbing my head against herself, he looked at her pale, soft body. Keeping his expressionless skull face, he picked up the two broken bones on the floor and promptly stuck them into his own eye sockets.

“This servant has failed in his duty. See no evil, see no evil. Please, young lady, carry on…”

“Hehe~~”

“Wait, don’t go! Please, save me!”

At last, he didn’t leave! He turned around!

“By the way, my lord, I have something to report.”

“Huh?”

“Alpha knocked his own head flying off while piloting a mech yesterday, and it still hasn’t been found. Lancelot and Second Miss Selena have sent out every skeleton helicopter available to search for it. They’ve even deployed the First Undead Tank Regiment. I thought such an important matter ought to be brought to your attention.”

“Also, Shizhenxiang smeared himself with laxatives again and went to the enemy’s granary to blow himself up. We’re planning to send someone to bring him back.” “None of that matters! Save me!”

But he bowed and left the room, his parting words trailing behind him.

“Please remember to maintain good hygiene, my lord.”

Hygiene, my ass! I’ve only got my head left—what am I supposed to do, watch out for a hole opening up in it?!

Wdnmd, is there anyone else around?! Somebody come save me!!

“Hehe, big brother~~”

“Eileen! The way you’re looking at me is getting weird too!!”

Hey! Wait! Don’t pull my jaw off!!

Aaaaaah!!

……

…

“Still…”

This kind of cozy everyday life isn’t so bad, even if it is a little weird.

Spending time with intelligent undead and girls from all kinds of races—isn’t this what I’ve always wanted?

“Hehe, I love big brother the most~~~”

Beside me, the silver-haired girl’s cheeks were flushed as she rubbed her face against my skull. Beyond the window, in the brilliant starry sky, the shattered crimson moon watched over everything.

But for this insignificant everyday life…

……

…

“Big brother, do skeleton soldiers really not have hearts?”

I rubbed the tip of her little nose and answered with a smile.

“I used to have one.”

“And now?”

“You stole it from me, silly girl~~”

“Hehe~~”

……

…

Fleeing, resisting, fighting, getting hurt.

The blood and tears we shed together.

The wounds we tended together in the dark.

For this insignificant everyday life…

Up to this point, we and they…

Just how much have we had to sacrifice…?
