Ophis-chan!

Arthur POV

"Hello Ophis, how are you doing this fine Tuesday morning?"

I know it wasn't the smartest thing to say to one of the strongest beings of the universe, but what else am I meant to say?

"What are you doing here?" I heard Ophis say behind me. I turned my head towards her and gestured her to come in front of me so I didn't have to strain my neck "Come sit with me. No need to stand there" I said to her with a smile. She instantly disappeared from my vision, though my senses were still able to track her movement, I turned my head back to the front to see her stood in front of me 'If it was anyone else, I would have assumed that was a show of power...But Ophis? I don't think she's the sort to do that. I don't sense any malicious intent or anything, so I should be fine'.

I saw that she was still standing so I gestured to the....Floor? Open area? space? In front of me. "Please sit. Onii-chan wont bite!" I said to her. 'I could very well be digging myself a hole right now. But...It could be so worth it if I'm not! Imagine a cute little Imouto Ophis!'. She looked towards where my hand was gesturing to and sat down. All emotion void from her face. "Hmm. Back to your earlier question. I'm just relaxing I suppose, not doing a lot right now. Waiting for school to start I guess. Well I would be, but I'm not sure if I'll be going in today, I quite like just relaxing here. Sona-Kaichou would probably beat my ass if I didn't though *chuckle*" Realizing I was rambling on, I looked to Ophis and gave her an apologetic smile and asked her the same. "What brings you here sister?"

She replied quickly saying "You". I held my hand up to my cheek and acted flustered. "My my. What can onii-chan do for you?". She carried on looking at me without any emotion, though I wasn't really shocked. 'A bad habit sister. Though I will help you! You'll be talking with your onii-chan in no time!'. In the space of 1 minute, I have realized I was a sis-con.

"Your human" Ophis said to me. A frown quickly marred my face "I know were not the same race. But I can still be your onii-chan! After all, us the only beings of infinity, we should stick together right?!" I asked with hope to Ophis, though she looked at me with the same straight face, I could sense her underlying confusion. She probably felt my aura when I came here and when I combined my cores, but I had already concealed them.

I walked slowly over to Ophis as to not startle her and sat down right next to her. I held out my hands to her. "Grab on" I said to her with a smile. She probably wasn't worried, so she quickly grasped onto my hands with both of hers. I then released my aura of infinity, using the pitch black core inside of my body, and let it smoothly cover us both. It was almost like a stream of water flowing around us.

Ophis had a visible reaction to this. Though still not much of one. She rose her eyebrows slightly in surprise. At the same time, she also released her aura of infinity and coated us both in it and to my surprise, our auras mingled perfectly, connecting with each other! Though the power of our aura put together was vast, there was no intent of harm or maliciousness. It was just soothing and calm.

I closed my eyes and focused on the power flowing through the both of us. I could see two cores of infinity. One of which I assumed was mine and the other was from Ophis. 'I wonder what would happen if I combine them. Maybe we'll grow stronger. Worth a try I guess' I summarized to myself.

As I connected our cores together, a large amount of life force seeped its way into me. "What's this?" I said out loud, surprised by what i was sensing. I knew for a fact that it wasn't my life force I was feeling. 'Fuck'. I opened my eyes to see Ophis staring at me.

My system glared in front of my eyes before I could say anything to her.

I looked over the notification I had just received from the system, showing no emotion on the outside, but slightly concerned on the inside. 'Lets just hope she isn't angry' I thought while continuing to observe her reaction, which was unsurprisingly still not a whole lot. "I can feel you" Ophis said to me, unblinking.

I grinned awkwardly towards her and said "Ah yeah...About that. Its probably because I bonded us together. Slight miscalculation on my part, I'll admit" I gauged her reaction and awaited a reply "I don't mind. It feels...Nice. We are the same. I'll allow you to stay in the dimensional gap with me after we beat baka-red".

I was surprised by her reaction. 'Hey Nabe, can you buy me a simple chocolate bar from the store please'

*Kaching*

{chocolate bar bought -50sp

I brought the chocolate bar out from my inventory, simply appearing in my hand. I sad smile appeared on my face, I put my hand on her head and ruffled her hair "I'm sorry sister but I don't belong in the dimensional gap. I live on Earth with all the people. I can visit you once in a while, you are of course welcome in my home anytime! But I can't stay here" She looked at me and tilted her head cutely. "I will come with you then. Stay together. We will defeat baka-red when you are done on Earth".

When Ophis had finished talking, a large grin had already formed on my face and I started cooing her "Hehe, that's my cute little Ophis-Chan! Here, here, eat this!" I handed her the unwrapped chocolate bar.

*Nom* *Nom*

Though it was barely noticeable, I saw the corner of her lips curve upwards as she forced the chocolate bar into her mouth. "Take it easy! Cant have you choking now can we!?". She nodded as a reply. "Okay, I'm sure I'll be needing to get to school sometime soon, we should head back. please conceal your aura, we cant have the devils in town getting scared! My name is Arthur Liones on Earth, but you can call me Onii-chan!" I said to her, grinning ear to ear.

"Onii-chan" Ophis said quietly with me nodding in rapid succession. "Ughhh, my Imouto!! So kawai!" I said grabbing her in a hug and spinning her around. "Okay, lets head home. Nabe will be waiting for us! She's my maid and lover, she will be a great onee-san for you!" I pulled her above my head and gave her a piggyback on my shoulders and grabbed her legs so she didn't fall. "Lets go!" I said as I concealed my aura, Ophis doing the same and opened up a rift back to my house and walked through, assuming I'd land where I left.

When we got to the other end of the portal I saw Nabe, waiting patiently as per usual. I walked over to her, with Ophis still on my back and gave her a kiss "I'm back my dear, can you tell me the time please". Nabe replied in kind with the kiss and answered my question "It is currently 7:56, 34 minutes before your school starts" I pulled Ophis off my back and sat her down on the island chair in the kitchen.

TIMESKIP TO AFTER SHOWER AND DRESSING

I ran back down-stairs and saw the both of them waiting for me." Alright, I'll be going now" I kissed Nabe quickly and ran towards the garage, though a presence was still following me, turning around, I saw Ophis "What up Ophis-Chan. Does my cute Imouto need a hug before onii-chan leaves?". She tilted her head and said "I'm coming".

I looked at her confused but decided it wasn't worth it. 'I'll think of something to tell kaichou, she might not mind, Ophis-chan will most definitely be quiet during class'. I smile at her and said "Come on then, make sure to hold on tight when we get on" I grabbed her hand and walked towards my bike. I slipped my helmet on her head, forgoing one myself and sat her on the back of my bike, I opened the garage and I politely asked Nabe to shut it for me after we left. I then got on myself. "Hold on around my waist Ophis". She followed my instructions and set off for my school.

'This will be interesting' contemplating how the day would go with Ophis.
