Koneko had collapsed.

She was in the middle of sparring with Berserker when she simply collapsed her breathing hard.

"Fine..."

"No, you're not fine." why didn't I notice something was wrong with her?

She might be good at hiding her emotions but that didn't mean I should have missed the signs.

She was sleeping far more often and took naps far more than usual.

I gently carried her in and laid her down on the bed before kneeling beside her.

She was burning up and sweating a lot now.

Taking out a napkin and a water bottle from my pocket space I cooled the water then used it to damp the cloth and gently wipe her forehead, once done I changed her clothes to a nightgown and covered her blanket.

Once I made sure she was conformable and her breaths began to calm down I cast [Structural Analysis] on her body.

What I got back was her chakra seemed to be running very low her body seemed to be quite strained.

It took a few more repeats to find out the reason to exactly why she was running low.

This world didn't have Nature Energy.

Even the Mana in the Air was so trifle, compared to how saturated the DxD verse was with Mana and other energies that were present.

Where the Age of the Gods never did end.

But here it was as if we were suddenly moved up to the stratosphere without having any time to adjust.

Unlike me Shirone was only Half Devil, while I was a full devil, Unfortunately, I couldn't regain my devil body as I only had a vague idea of how a Devils body works.

I was only able to revive Iskander because I already had a living Template in the form of a young Waver Velvet.

"Sempai... Fine." She breathed out. Her face was flushed.

"Oh, you little sweet Kitten." I leaned in and gave her quick peck on her cheek and a smile sprung from Shirone.

"She is quite strong isn't she?" Sapphire complimented as the Kaleidostick floated beside me."What seems to be the problem though? From what can see her mana is not depleted. Nor is there anything physically wrong from my scans."

"It's not her Mana that's the problem. It's her Chakra."

"Chakra?"

"Chakra is the combination of physical and mental energies, and as a Nekoshou she is born with the ability to generate and use Chakra. The problem here is that, even with my little Kitten's huge Chakra reserve's whose potential to grow was boosted ninety fold using the Queen piece, it was only a matter of time until she ran out of Chakra as her body is unable to generate more Chakra than she uses. The Chakra control exercises I taught her helped increase how efficiently her body uses it and her capacity by a lot. I can easily bet there are no other Nekoshou who is as efficient or has a large chakra capacity as Shirone. "

"Then what seems to be the problem?"

"The problem is that I taught her to control her Chakra after we arrived in this world. Not before, which wasted more of her already dwindling reserves, had I taught it to her before it would not happen. But now as this world doesn't have any Nature Energy in it, Chakra is flowing out from little Shrone- "

"Entropy!"

I nodded. "Correct. As I said Shrone now only needs barely a fraction of what she did before. But her body is exhausted trying to fill up her reserves."

"Which keep getting drained since this world doesn't have any Nature energy, the planet is literally trying to suck her dry. The poor child. Is there anything you can do to help her?"

My mind was moving fast as I used [Though Acceleration] since I found out what exactly the problem was trying to come up with a solution.

"I have three potential solutions."

"Truly?"Sapphire asked pleasantly surprised.

"Yes, Shirone? Can you hear me?" I asked her softly.

"Yes... Can.." She breathed out tiredly.

"Good. You heard what I said right?" she nodded. "Here are the ideas I have. First I can create a barrier around this room to prevent any Mana or Chakra from leaving it. It will help you recover as it will prevent more Chakra from escaping your body into the earth. But the moment you step out of the room your Chakra will begin to leak again and while your Chakra reserves are positively ginormous, the moment you start using a lot of Chakra you will eventually get Chakra Exhaustion again and your body will become strained again. "

I paused as I saw her looking at me intently, her cute yellow eyes paying attention to what I was saying and her furry white ears twitching, it took all the willpower that I had to not just glomp her then and there and settled in gently petting her instead.

"The other way is to make a seal on your body so none of your Chakra can escape it."

She shook her head at that.

Negative. She didn't like it.

So that left the final solution but that depended on Sapphire.

"Sapphire. You already said even if I accept the offer to be your master now I cannot use you to travel to other worlds."

"Correct, that function is blocked by Administrator Zelretch, if you do wish to use that function you need Administrator privileges."

"Which I need to get from Zelretch himself" I sighed. There was no way that was happening. "Can you look into alternate worlds at least? Even if you are not allowed to take me there."

"That... Yes, I suppose that I can do that. Yes, how can this help?"

"Good, you can analyse Shirone right? Can you sense the Chakra?"

"Yes. I can, though I didn't know what the strange energy was until you pointed it out to me."

"Good, don't ask me how but I know, but there is a world out there in the multiverse, a world where humans can use Chakra. Except they have a special circuit system and limiters within their body which prevents the Chakra from flowing freely as my little Kitten does. What I need is of you can get me the information I need from a structural analysis spell so that I can make an Artificial limiter using once I have enough information on how it works, that way Shirone can unlock the limiters when she needs to fight and keep them on when she's not."

"That...that might actually work...if such a world indeed does exist. However, given there are infinite worlds where anything can happen I suppose that is not the question. It is just a matter of finding out one of the worlds."Sapphire nodded as she considered my plan.

"What do you think Shirone?" I turned to my little Kitten and she nodded accepting it.

"Alright then." With that Sapphire extended her handle ready to form a contract, but before that could happen we were interrupted by something slamming into my chest that literally knocked me down on my ass.

"Sister!"I heard Sapphire say and as I looked up I saw Ruby out of her box.

"Please take me instead!"Ruby said floating close to my face.

"Sister! I picked her first! Besides, you could have come out anytime before! Why now when I'm about to make a contract?"Sapphires voice raised agitated and annoyed.

Ruby turned away from me and floated to her sister."Well, I had to know who exactly my would-be master was, after all, I can't just take anyone."

"Then you could have talked to her as I did, instead of spying on Lady Rias!"

"Ohh, well that's boring you know!"

"Guys!" I interrupted the two literal floating talking magical sticks. They stopped and turned to me. "How about I take both of you?"

"Both of us? But that would require us to combine together."Ruby began.

"Lady Rias," Saphhire began,"No human can handle the strain of our combined form. Their magic circuits would not be able to do so."

I grinned "You guys are forgetting something." I paused. "I am a Devil Princess, not a human, I literally throw mana around like candy.."

I watched as Sapphire blushed in embarrassment on forgetting that fact and Ruby burst out laughing."A master that can use both me and my sister? Truly we have been blessed. Never would I have thought I would come across someone like that."

"Indeed." Saphhire nodded.

With that Sapphire and Ruby spun around each other before combining into one with a burst of Mana.

And as soon as I grabbed the handle it began.

''Registering New user, Rias Gremory as Primary user." Sapphire began.

"Initiating contract." along with Ruby.

"Forming Prana link." The two of them working in harmony for the very first time with a single master Something they never thought possible.

"Forming telepathic link."

"Registration of new user Rias Gremory Complete."

"Booting up user-approved systems."

"Boot completed."

"Begining transformation."

And within seconds I had transformed into a Magical Girl in a flash of prismatic light.

The first thing that came to my mind was that Sister Serafall was going to love this.

As the light died down and I took a look, I found Ruby Rose costume was replaced with Illya's Zwei form.

It was actually rather underwhelming..if you don't count that during the few short seconds I felt them link up to my core.

My very soul.

Since I didn't have magic circuits and I was a devil the mana and information were channelled directly from and to my core.

"Transformationcomplete." Sapphire and Ruby finished together

"Much better than Serafall," Shirone added.

"Of course it's better, a fake magical girl can't beat a real one after all."Ruby proclaimed loudly.

I snorted out at the sheer Irony of that statement being said in a multiverse where Shirou Emiya existed.

Just as Ruby and Sapphire were about to activate I heard a loud sound and a crash outside that made me stop and turn around.

"AAAAAAAAAARTHUUUUUUUR!"

Fuck.

Did Saber come here?

"I'll be back Shirone, sleep well alright?" I gave a quick kiss on her cheek then

I quickly erected a barrier around Shirone's room to keep her safe and one to keep her Chakra from escaping before I left the room and closed the door behind.

Turning around I saw Berserker literally smashing into Saber and pushing her out through the gate and out of the temple and down the stairs.

And a terrified Irisviel who was standing just next to Saber a second ago.

Guess Berserker couldn't wait anymore.

Thankfully Berserker took it out of the temple.

Kariya was out with Sakura so, he wasn't here at the moment, the sun had just set and some of the monks would definitely be attracted to the sound but this was not the time for that.

"Well, it nice to see you miss Irisviel?" I greeted her as I approached her.

"Who are you?"

"Right I guess I'm not in my disguise anymore, so you didn't recognize me. I'm Caster."

"Oh." She calmed down. Before her eyes lit up. "Saber was right, after all, you really aren't Merlin after all! And you look so young too! "

So Saber knew that I wasn't Merlin? Not surprising.

I raised my left eyebrow. "Considering the amount of time she was around the man, I would be more surprised if she did not realise that I wasn't Merlin, my aim was not to deceive Saber but the other masters, since Merlin is a name quite well known as one of the most powerful mages the others would be hesitant to attack me even if I was a Caster. And considering Saber introduced me instead of myself there would be no doubt that I among them that I was indeed Merlin. "

"Oh, I see, that is quite clever."

"My Lady is indeed quite clever, but My Lady I believe we still have something we need to do." Sapphire interrupted.

"Oh my, a talking Wand? How mysterious!." Irisviels eyes glowed with curiosity.

"So, why did you come here?"

"Oh, I just came to visit."

"That nice of you, but Koneko is not feeling well at the moment. "

"Oh no! What happened?" The woman wore her emotions on her sleeve. I suppose she could help a bit, Irisviel is too nice to harm anyone really.

"Come with me," I said turning around and heading back to the room.

I lead her back to the room where Shirone had fallen asleep and showed her what to do.

Irisviel didn't even question how different Shirone looked.

I pulled out a few bottles of cold water, and fresh milk from my spatial pocket and handed it to her.

I didn't even have to say anything as she took the cloth and wrung it dry into the bowl before dampening it again and placing it gently on Shirone's forehead before she gently began to pet the kitten. She was a Mother after all.

"Ready Master?" Sapphire asked.

"Ready," I replied preparing myself mentally for anything that might happen.

With that, I started to see flashes of Kaleidoscopic light as Ruby and Sapphire began to search through the multiverse using the Kaleidoscope for a world that fit the description that I gave them.

I don't know how long it would take but I'm willing to go as long as necessary until they find it
