Arpious of the Planes

And once she noticed all the wolves were dead, she ran back over to me before affectionately hugging me.

"D-did I do good?"

"Of course,"

What kind of monster did I make my little sister…

We went hunting for a bit longer before I noticed that her skills weren't going to deteriorate any time soon.

Even if she lost her skills in fighting, she still has overpowered skills that still pose a threat to me and the kingdom.

"Okay, let's head back," I say as soon as I see her take down a yeti with one swing of her arm.

I chuckled to myself as she ran back over to me, but her affection had dwindled a bit.

It's already wearing off… Soon it will completely disappear.

"Big sis, let's go back," She says, her original personality beginning to shine through.

She was a bit colder than before, and her manner of speaking was slowly becoming more demanding… which gave me a bit of information on her real identity.

We soon arrived back at the cabin, and Arpious crashed on the couch, hugging the pillow.

I'll redo the brainwash later… I'm too exhausted from taking care of her today.

I crashed next to her, and she snuggled into my grasp… as we slowly fell asleep, listening to the crackle of the fireplace.

…

Suddenly, a wave of bloodlust began to suffocate me like a wave pressing me against the bottom of the shore.

I snapped my eyes awake and pulled my hand in front of my face, just barely blocking a katana that pierced straight through my hand.

But as I flinched in pain, I gripped the blade, preventing the attacker from pushing it any further.

"Who dares- Arpious?"

"What did you do to me…?" The woman above me asks, but I didn't see a monster… but a shadowed silhouette with two brightly glowing yellow and red eyes.

Her X and diamond pupils shone in the dim cabin as the fireplace was completely extinguished.

"Shouldn't you be treating your savior with care?" I joked around, but a drop of sweat ran down my cheek as I slowly pushed the katana away.

She didn't resist, and she even retracted the katana, pulling it straight out of my hand.

"ARGH! Motherfu-"

I grit my teeth from the pain, but my regeneration quickly took care of the gaping slit in my hand.

"What the hell did you do to me?" She asks once again, relighting the fireplace with an extremely warm and comforting white flame.

She sat down on the carpet, staring up at me, but I couldn't help but feel that she was still looking down on me.

"*sigh*... I wanted to try and use you to my benefit, but it seems you're too strong to be controlled," I muttered, rubbing my hand.

"And why?"

"Why not? If I could acquire your power, we could potentially contest against the other large kingdoms," I responded, slumping down onto the couch.

"Dammit… Which plane is this?"

Ah, I was right… She is a plane walker.

"It doesn't have an official name, but we just call it the Plane of Ice," I responded, conjuring a ball of ice within my hand, but she quickly noticed and shot it down with black flames that melted it in an instant.

That ice was made from [Primordial Storm of Ice]... How strong is she really?

"So I finally managed to escape…." She muttered to herself.

"Did you come from a corrupted plane?"

"You mean a broken plane?"

"Yeah, basically,"

"Then yeah… I did," She muttered, and her face paled upon thinking back onto her previous experiences.

"Must've been a traumatizing experience… Most plane walkers don't survive those planes… So how long were you on it?"

"Maybe about… 20 years… Well, it might be longer because I stopped counting after year 5,"

Twenty years on a corrupted plane… This poor thing.

"Well, I'm going back to sleep. Just don't kill me, and you can leave whenever you want. I won't say or do anything,"

She glared at me for a bit before spinning around and laying in the opposite direction of my face.

"Goodnight," I muttered, and she fell asleep within only a few seconds after I muttered those words.

It seems she's exhausted… but there's no way I can go to sleep now with all this adrenaline rushing through my veins.

I could… kill her now.

My eyes grew colder as I conjured a giant icicle in my right hand.

Krkkkkk

She didn't react, and as I suppressed my bloodlust to the max, I hopped off the couch and slowly approached her.

She was lightly snoring, and just as I raised the icicle above my head, I heard,

"No… No… Please save me… No… Get away from me…."

She began to toss and turn in her sleep.

Krkkkkkk

"*sigh*... Shit,"

I picked her up gently, making sure to not wake her up, and then placed her on the couch before covering her with my only blanket.

…

I awoke in the morning to see Arpious gone from the cabin, nowhere to be seen, which I had already expected.

But I still clung onto a sliver of hope that my newly acquired little sister still had some affection for me… and walked outside.

Arpious was lying unconscious on the snow, but the snow was completely soaked in blood that I noticed came from her mouth.

I quickly rushed over to her and checked her pulse, which was slowly beating, so I quickly brought her inside and used the only healing skill I had.

[Healing of the Frozen Moth Queen]

A blue aura surrounded my hands as I placed them against her stomach, which I assumed the internal injuries were.

"The damage must've been done so many times that even her regeneration slowed down," I muttered as I noticed how crushed her internal organs were.

How was she able to act all cute like that before without showing even a hint of pain.

After a few hours of her sleeping, she finally woke up and dashed sporadically towards the edge of the room, as she was frightened by my appearance.

"W-why didn't you kill me? You had so many chances," She asks, and I just smile because of how cute she was.

"Why would I kill my cute little sister?"

She blushed profusely, unable to meet my eyes as I looked at her with a warm smile.

"I-I guess I'll stick around just a bit longer," She muttered, and I got up from the couch and picked her up by the armpits.

I then stood her up before hugging her tightly.

And suddenly, she began to weep into my collar bone.

"I miss them…." She mutters before tasting her own salty tears.

"Miss who?"

"My wives and children… I thought I had gone better… But it just became worse," She muttered.

"We're you gender-bent?" I asked as being gender-bent by an illusionist monster wasn't uncommon, but something like that wouldn't have lasted this long.

"No…" She muttered.

"Well, it's okay… I'll try and help you get back to your family,"

"No, I can't go back… Otherwise, they'll die… and so will I,"

It seems she has her own circumstances, so I won't pry for now and instead will take care of my new cute little sister.

After another few minutes, her tears had completely dried up, and she had calmed down much more than before.

"Do you feel better?"

"Mhm…"

"Are you hungry?"

"Mhm…"

"Okay, I'll get you some food. Just sit tight," I say before placing her on the couch and covering her with my blanket.

I then made my way out of the cabin and back into the forest, where I went hunting for some tasty monsters…

…

As I dragged the skinned corpse of a Frost Boar into the cabin, I was greeted by Arpious who was sleeping once again.

"Wake up~," I said as I threw the skinned corpse into the fire, watching it roast as Arpious slowly woke up again.

"So hungry," She muttered before walking over to me and hugging me tightly.

"Alright, it's almost done,"

Soon, the smell of freshly roasted boar filled the cabin, and I even had to open up the wooden windows as the smell was getting a bit too thick.

"So tasty," Arpious muttered, sitting on the carpet in a position unfit for a woman.

"Close your legs," I said as I dug into the leg of the boar.

"Oh, sorry," She responded, pulling the edges of her robes down and crossing her legs.

Suddenly, she began to choke on a large chunk of meat, so she went to go grab the cup of water but fumbled and knocked it over

"*sigh*... Eat as much as you want. It isn't going anywhere," I say, handing her my cup of ice-cold water.

"*cough* *cough* *cough* *cough*... Thank you," She responds before digging back into her portion of the boar.

She is just so cute…
