Chapter 7.

Once I was inside the school grounds, I saw Tomoko standing by a tree, waiting for me, a look of worry on her face.

She quickly perked up once she saw me and a smile bloomed that made her look so much more beautiful in her uniform, her thighs rather prominently displayed due to her short skirt.

"Nii-chan! There you are, I was getting worried," Tomoko said, as she walked over to me, "What was taking you so long? And where did the cross come from?"

I… I didn't really know what to say to her, mostly because I was still pretty worried about this apparent Devil presence in the school, it was making me nervous.

Were the faculty all Devils? Was that how they controlled the school? Would that mean that some of the students were as well? Agh, this was terrifying to think of.

But I should figure out what I'm going to tell Tomoko first…

Looking at Tomoko for a moment, I eventually came to a decision.

I was going to tell her about magic… and everything I've learned. Just not… now.

"Ah well, I'm sorry about taking so long. Someone helped me out… then we got to talking, and- do you remember Irina?" I asked, causing her to nod a bit confusedly.

"Yeah? I remember him, he was like my best friend when we were kids" She said with a small smile.

…No matter how many times I tried to tell her, she simply didn't believe that Irina wasn't a boy. At this point, I've just given up.

I'm pretty sure it's because of her bishounen pretty boy fantasies… and her fujoshi fantasies as well. I damn well knew that she 'shipped' the two of us together… even when we were kids.

I still regret finding all of those drawings she did in middle school.

"Right, so uh the person I helped apparently knew her, or well at least the Shidou's… they're doing well," I said, causing my sister to give me a slight glare, and I just knew that old argument was going to resurface.

"Ah, that's nice to hear. But that doesn't really explain… anything" Tomoko said after a moment.

"Well, how about this. I'll tell you after school, there's just some things going on that I think would need more… privacy" I said after a moment, causing her to nod.

"Alright, alright… I get what you're putting down" She said with a lewd little grin.

And just like that, I knew that she completely misunderstood me.

But as I went to correct her, the bell rang and she quickly ran off.

"I'll see you later, nii-chan!" Tomoko said as she left my line of sight.

Well, alright then. Time to get to class, I guessed. So with that, I made my way to the Third Year classroom, and saw several of the students already there.

So I quickly went over to my desk, and got ready for the class to start.

"Ah, hello there Hyoudou-san. How are you doing?" One of my fellow students, Abe Kiyome asked as she walked up to me.

She was a pretty girl with brown hair that was arranged in multiple drill-like curls, and she gave me a cute smile.

"I'm doing fine, Abe-san. How about you?" I asked with a small smile on my face, even though I knew exactly what she was going to ask.

"Doing great! I was wondering… would you like to join the tennis club? You look decently athletic, and I'm sure that you could do great in it" She asked with a small grin, as she leaned over my desk, causing her breasts to get pushed up in a rather tantalising manner.

"No, Abe-san. I'm already a part of the cooking club, I've told you this before" I told her, causing her to give me a small pout.

Last year she had asked me at least a dozen times to join the tennis club, and I've refused the same amount of times. It just wasn't a sport that interested me.

"Mou~ Come on… please?" She asked, causing me to shake my head.

She then slumped her head in defeat, and then walked back to her desk, though I noticed that she kept giving me little looks.

I just knew that this victory of mine was going to be short lived, and she'd likely be back next week…

But when the teacher came in, I was given a reprieve from those thoughts and paid attention to the class.

Affinity Sense Sailor Moon Divination (200 CP)

You are a soldier of your chosen celestial body, and with that celestial body comes a sense for a certain element or concept. For example, if one would be Sailor Eris, they could carry a sense for detecting locations of great instability or able to discern emotionally charged situations, as they have a chaos sense. If someone carries a sense for water, they could sense breaks in the water pipeline underground or tell if a body of water has been tainted, magically corrupted, or polluted. If one is not a Senshi, they may choose an element to carry a sense for.

Affinity Chosen: SUN.

I was sitting in class, ignoring the teacher and doodling a picture of a skeletal magical girl fighting a mutated blobfish monster, when a sudden sense of knowledge went into my mind.

Apparently, now I was able to sense an element that I already had an affinity for… and in an instant, I could see a hazy golden yellow glow from everyone in the room.

"How strange…" I muttered to myself, as I noticed several people having larger amounts of this hazy energy around them. It was so… weird to see, but it also felt completely natural.

And for some reason, I could feel a warmth around me, as if the sun itself was enveloping me in a loving embrace.

Thankfully, the golden light eventually receded, and I found myself able to see things like normal.

But with a single thought, I could see that same light coming out of every person that I saw.

Strangely, men had a higher average level of the odd golden light. And I didn't really know what to make of that.

I don't really know what I could do with this ability, but I guessed it was pretty okay.

Paying attention to the class for a moment, I saw that the teacher, a rather stuffy older woman, was going on and on about… something.

Honestly, even though I was trying to pay attention, her words just seemed to go in one ear and out the other.

Shrugging a bit, I just went back to my doodling. It's not like I really cared much about the first class of the day. What was the homeroom class even for other than attendance?

But eventually, thankfully the bell rang and I could finally leave homeroom.

As I left though, I noticed that Abe-san was still watching me, so I quickened my pace to the next class.

The next class wasn't really anything to write home about, so I just drew some more pictures.

Thankfully it was an art class, so the teacher didn't really mind what I was doing, and just let me continue with my little sketches.

After around an hour, the class was over signified by the bell being rung, so everyone cleaned up whatever mess they had and quickly left.

It was lunch time after all, and I just remembered that I had two extra bento boxes to give out.

I figured that I'd go find where Koneko was first, mostly to spare my sister from her friend's thieving attempts.

So with that in mind, I walked up to the rooftop, where I was almost instantly met with my sister's panicked face.

"Ryuu-nii! Quickly, you have to stop Koneko! She's gone crazy!" Tomoko screamed in horror, as she hid behind me.

Looking at the so-called 'crazy Koneko', I saw that she was just standing there… staring at my sister.

Or well, more specifically, she was staring at the bento box that she was holding.

"Bento" Koneko said cooly, as she stared directly into my eyes.

Taking off my bag, I slowly zipped it open, and pulled out yet another bento box.

"Take this," I said, as I slowly passed it over to her, treating the whole situation like feeding a wild animal.

Mostly because I found it kind of funny.

She grabbed the bento box and moved back, before opening it. And I could tell from the way that her eyes lit up ever so slightly, that she was happy with what she saw.

Grabbing the chopsticks that I added to the meal, she picked up a piece of chicken and placed it in her mouth.

"Nnn" She made a small noise of contentment as she sat down, before slowly starting to eat the rest of her new lunch.

So I slowly walked over to her, my little sister following with her own bento box.

"You're not going to take this from me, are you?" Tomoko asked, causing her friend to shake her head, "Uh… good"

With that, Tomoko sat across from the other girl, who just gave her a small nod.

Tomoko slowly opened her bento box, making sure to watch Koneko the entire time, but as she didn't move, my sister brought a piece of chicken up to her mouth.

…And ate it, letting out a sigh of relief, as she was finally able to eat her lunch.

"You know, if you like my cooking so much I could keep making you extra. Honestly, I'm just happy that my little sister made a friend" I said with a smile, as she looked at me, tilting her head a bit.

"That would be nice," She said after a moment, giving me a very slight smile. Barely imperceptible... classic Kuudere stuff.

"Right then, I've gotta go now. I made Shitori-san some lunch as well, and I don't want it to get cold!" I told the two of them, before moving back to the door leading back into the building.

"Bye nii-chan!" Tomoko said after a second, causing me to turn and see her giving me a small wave.

Koneko on the other hand was just giving me an odd look, mouthing something under her breath.

With that, I left them to their own devices and started to walk over to the Student Council Room.

As I was walking down the halls to get to the Student Council Room, I'd gotten distracted by yet another tearing sound.

Honestly, I was getting sick of this shit. If I wasn't getting magic, could it at least not tell me? Ignorance is bliss and all that sort of crap. But just hearing the sound of paper tearing is so damn annoying.

But I shouldn't think about that stuff, and instead focus on getting the bento box to Shitori-san.

Thinking about it now, maybe I should have seen if she was fine with this sort of thing… it's too late now, as I've already reached the door to the Student Council Room.

Knocking on the door, I flinched as it was opened rather quickly, and I was met face to face with…

Shitori-san was standing in front of me, quirking an eyebrow as her eyes roamed my body before stopping on the cross necklace that I was wearing.

"Ah, hello there Hyoudou-san, did you need anything?" She asked, and even though she was doing a good job of hiding it, I could tell she was irritated by something.

"Yes, uh Shitori-san. I was making lunch earlier today, and I ended up making a bit too much. So, would you take this bento box?" I asked with a smile, causing her to look at the bento box in my hands.

"…Sure," Shitori-san said after a moment, before stepping to the side and letting me see further into the room, "Come in and set it on the table"

"Oh alright," I said, as I walked into the Student Council Room, not really caring as she closed the door behind me, "Uh which table do you want me to set it on?"

There were quite a few tables in here after all.

"That one," She said with some sort of tension to her voice, as she gestured to the table at the end of the room, causing me to give her a simple nod.

Walking over to the table she gestured to, I placed the bento box on top of it.

"So, what sort of work do you do in the Student Council, Shitori-san?" I asked as I turned around to see… Shitori-san with some sort of magical glyph pointed toward me. And I noticed that there was some sort of glowing line directly in the doorway.

"Hmm, I was right, the wards picked up active magic. What are you doing here?" She demanded with a glare, the magic flaring slightly.

I looked at her for a moment, honestly I didn't know that Shitori-san was a witch. Or a magical girl? Either way, that was awesome.

"Well? Are you going to tell me what you're doing here?" She demanded, the bright blue magic circle in front of her hands glowing menacingly.

"I was… giving you a bento?" I said, gesturing to the bento box incredulously.

"No. What are you doing here, in Kuoh!?" She said, a frosty tone to her voice, "Who are you with The Grigori? The Church? What Faction are you a part of?"

"Uh, I'm in Kuoh because I was… born here? And I don't really know what you're talking about. My own?" I said, honestly not really knowing what she was talking about.

Sure, I knew about Christian Mythology, but I also knew that the various denominations probably wouldn't want to work together, so that can't be what she meant by 'The Church', right?

And what the fuck was a Grigori?

"A likely story," Shitori-san said coldly, before sighing slightly, and dropping the magic circle, "Tell me. Ryuuji-san, what do you know of magic?"

"That it exists? Like, I found out about it a couple of days ago…" I said with a small shrug.

"And how did you find out about it?" She asked, well more like demanded.

"…I broke a plate with a bubble," I told her, causing her to grit her teeth.

"Show me" She practically commanded, so I just gave a little shrug and pointed at a wall.

"Uh fine... Zap!" I intoned, and just like that, a small beam of glowing yellow bubbles was fired, and impacted against the wall.

It didn't really do anything to the wall, other than splattering against it… and scorching it slightly.

Huh, why were they yellow now? Was that because of one of the magics that I got?

Looking back at Shitori-san, I saw her slumping slightly as she palmed her face.

"Right, of course, there'd be some sort of mini Merlin here. Why wouldn't there be?" She muttered to herself, before a small smile formed on her face, "So what spells have you learned so far?"

"Nothing much, just Zap, and Thought Acceleration. Oh, and a bit of divination, but that's about it" I said, as those were the only spells I knew.

I didn't really count knowing how to place spells into objects as a spell, and neither was my ability to leap vast distances. And it wasn't like I was going to trust her with my every secret. I'm not stupid.

"Hmm… what do you feel about joining a Peerage?" She asked, causing me to shrug. Huh, I have been doing that quite a bit lately.

"I don't know what that is. But anyway, I have to go and do… things" I said, as I quickly walked away, thankfully she didn't even attempt to stop me.

But then I stopped in the doorway as I remembered something rather important, as I turned back to her.

"Oh right, Shitori-san. You should be careful of the staff, from what I heard, they're all Devils" With that, I closed the door behind me and walked away, happy that I was at least able to warn her of the threat.

After leaving the Student Council Room, I went back up to the rooftop with both Tomoko and Koneko.

"Ah, nii-chan you're back," Tomoko said happily, as her friend napped on the roof.

"Yeah," I said quietly, not wanting to disturb the sleeping girl, I sat down next to my sister and opened my own bento box. I was so damn hungry...

Once I started to eat my lunch though, I felt a hand slide into my pants.

Sharing a look with my sister, she gave me a little grin as she snaked her way under my underwear, and grasped my hardening cock.

"Don't make any noises now, nii-chan. We don't want Koneko-chan waking up, now do we?" She whispered, before blowing into my ear.

The cool air that went into my ear canal caused me to stiffen slightly, as she ran her fingers along the side of my shaft.

My lunch almost completely forgotten, my sister reached the head of my member, before circling a finger around it.

Her teasing started to get quite a bit more intense after that, rubbing her hands along my shaft, before drumming against it, tapping my cock in a rhythmic pattern.

Tomoko then stopped what she was doing, giving me a little lewd look before she firmly grasped my shaft, and started to jerk me off.

Her soft hands massaged my cock, tugging on it in a slow and methodical manner, and I felt my release was imminent.

But as my cock throbbed and pulsated in her grasp, she… stopped, causing me to look at her, and see Tomoko giving me a teasing grin.

Then, she came to a complete stop, pulling her hand out of my pants, and leaving me right on the edge.

"Really?" I muttered to her, as she flexed her fingers, before leaning back against the wall.

"You leave me in suspense? I leave you in suspense" Tomoko said with a little smug smile, as she sniffed her hand which was covered in a decent amount of my precum.

Then she looked at me for a moment, and I could tell that an idea was flashing in her mind, before she silently moved towards the sleeping form of Koneko, and slowly but gently pushed one of her fingers into the girl's mouth.

I watched as the white-haired girl suckled on my sister's precum-covered finger, as if it were some sort of treat, swirling her tongue around the digit to get every little bit of the precum off of it.

When she was finished, Tomoko decided to quickly move back to where I was sitting.

"Holy shit that was so hot" She mumbled with a faint blush, as she looked at her now saliva-coated finger… before putting it, along with the rest of her fingers into her mouth.

It would have been hot… had she not been essentially shoving her entire fist into her mouth. Typical Tomoko, making something that should have gotten me raring to go, into a comedic little scene.

But even when she was being kind of goofy, she still made her actions look so damn beautiful… or maybe I was just seeing her in a whole new light.

I just sat there with my sister, who was rather focused on her little 'tasting session', as my cock slowly softened until I was finally no longer pitching a tent in your pants.

Then, I looked over to Koneko, to see that she had woken up, still laying on the floor, but looking at both myself and my sister rather oddly.

And then she started to lick her lips, a confused look on her face as she sat up, causing my sister to quickly take her hand out of her own mouth and hide it behind her back.

"Hnn…" Koneko hummed, as she looked at the two of us, but whatever she was going to say was drowned out by the sound of the bell.

"Ah, looks like it's time to get back to class!" I said rather forcefully, as I packed everything up, got up, and went down the stairs as quickly as I could.
