I quickly summon my fallen angel with a Reiryoku release that is too high to be able to hide with the little control I have of this weapon, using the reversal and the fallen angel, I try to split the Sephira in two while forcibly inverting it.
A huge energy release occurs, causing a dazzling glow as I begin to split the Sephira in two, it is working relatively well, but a lot of my Reiryoku is being spent.
So if Kurumi tries to kill me, she would probably succeed because I'm spending a lot of energy, but I pretend everything is fine until it's over.
"Aurelio-san, the DEM is coming, will it take long? They'll probably arrive in 3 minutes," Kurumi asks as one of her clones arrives.
"It's ready, you can teleport me," I am pulled into her shadows, holding two "Sephiras," both containing half of the original power. Of course, now that it has been inverted, it is no longer a Sephira, but a Qlipha.
We end up being teleported to a building somewhere, and I sit on the floor to rest.
"You really did it...who would have thought," Kurumi says, looking at the two crystals in my hand.
"It's yours, I think you can insert it into yourself alone, I've already facilitated the process," I've modified both slightly to be able to use them more easily without affinity.
"...Of course, but if it fails, I'll be the one who loses out," She murmurs as she takes the crystal. She moves the crystal and places it near her chest, and the crystal immediately begins to connect with the Sephira she already has entering her body.
'My plans have changed quite a bit...but it's okay...' I also try to put the Qlipha in myself, something I've never tried before, but I'm curious to see the result. My Fallen Angel has already been undone before coming here, so I'm without my weapon.
"I feel...normal? Nothing seems to have happened," Kurumi says as she sees that there were no differences.
"Were you expecting to explode?" I say somewhat sarcastically, and she gives me a dirty look, as if considering that I thought of that as an option.
"Try to summon, the name is Beelzebub since it's a demon king," I say, not knowing if it really worked.
"...[Beelzebub]" A faint glow occurs as she speaks the name of the demon king and summons a book. The book is smaller and less detailed than the one in the anime, showing the loss of power of the demon king.
"...Certain powers have disappeared...I can't control things by writing," She says as she looks at the book and tries to use it.
'So she got the side that collects information...' This is one of the most useful parts, although it was expected, since what I want is the other ability.
"[Beezebub]" I try to summon and I also manage to summon a book, but this one is also smaller and less detailed than the one in the anime. From what I see of the details, both books don't have what the other has in appearance.
'So if I use my Reiryoku, my Reversal, and the Beelzebub, I should be able to create the Nibelcole...' Having the help of the Nibelcole will be very useful. I don't know how it was made in the anime, but I'm sure I can replicate it with my powers.
It will basically have a devoted army, and although they are weak individually, they are strong because they are an army. They were probably made using spiritual power, the demon king, and technology.
So it's something I can do, but I still need to test it. I look at the pages of the book, they don't show much, in fact they are practically blank, but I think I have the power to write something and "force" it to happen.
Similar to what Nia did in the anime, making Shido lift her skirt, a very useful tool, although it can probably be overcome with strength.
"Aurelio, now you must tell me how to make your Fallen Angel, you said you would teach me, your plan worked, and we both have Nia's demon king, but this still doesn't complete my payment."
'Teaching something so powerful to someone like her can come back to me like a boomerang...' I sigh as I pass on that knowledge to her.
I begin explaining to her the principle, what needs to be done, and the general functionality. I spend almost an hour explaining how she can do it, and after that, she is truly surprised by the logic behind it.
"Aurelio-san, you really have some crazy ideas, how did you come to this conclusion?" She questions me, truly surprised.
"...I don't need to tell you about that, I've already taught you what was promised," She pouts, but nods her head.
"Can I know what you plan to do with half a demon king?" She asks me as I think about how to get the Nibelcole created.
"I have ideas, anyway, I need to go home, could you send me?" She sighs and uses the shadows again while sending me to a neighborhood near my house.
I start walking, deactivating my astral dress and just holding the Beelzebub.
"Will you keep following me?" I ask as she follows me.
"I'm just curious, but if you want me to leave, that's fine hihihi," She says as she disappears, but of course, she'll use the Beelzebub to find out what I'm doing, but since she can't read minds, she can't know exactly what I'll do.
As I go home, I do several processes with the reversal, trying various things with the Beelzebub. If I focus, I can see Shiori and even control her movements, as well as anyone else.
Although with many limitations, it is still a very useful thing, and this useful thing will no longer belong to Isaac Westcott.
"..." I release a bit of Reiryoku, but I'm careful not to alert the DEM or the AST. It's much more complex than I thought it would be, but it's almost ready, and I'm sure I can convert the pages of the Beelzebub into a body for the Nibelcole.
The Goetia knowledge I analyzed is being used to form an initial processing base for this creation.
As I get closer to home, I can already feel Mukuro's Reiryoku, and I can tell she's not happy.
'I think this will do' For now, I think I've managed to do something that can convert the pages of the Beelzebub into the body of the Nibelcole, but the thing is, it needs a "center" to exist.
So I end up making my body this "center" to be the source from which they can be maintained. They are basically an immortal army that can still exist if the source, which is me, exists.
"...It seems the number of them is limited by how many pages I have..." Unlike the anime, where Isaac seemed to have no limit, I'm limited to how many pages I have in the Beelzebub, although there are many pages.
I try to make just one page turn into the Nibelcole, and soon the page takes a little bit of my Reiryoku and detaches from the book, the sheet glowing slightly as it takes the form of a girl.
'Oh...it worked' I look at her forming, the astral dress reminds me a lot of Nia's, like an incomplete version.
"..."
"Father!" She speaks animatedly with a smile. I guess I don't like being called father much, but I suppose it doesn't matter.
"Nibelcole, I need you to collect some information for me, can you get information about the spirits in general?" I don't care about this request, but I want to see how far the Nibelcole will go for me.
"Okay, father! I'll do it with great success," She has a cheerful and somewhat relaxed tone as she floats a little above the ground.
"You can go, and come back in 3 days." I don't know where to use her, but she'll be useful for some of my goals. She soon starts flying away to somewhere.
I won't make too many of them because this is just a test. Maybe it was a success, but I'll only know that in a few days when she comes back to me with information.
I go home and open the door, finding Mukuro in front of the door. I took quite a while to do all of this.
"You...you're smelling like women...more than one," She looks at me with that empty gaze as if judging my soul.
"How many girls?" I ask curiously.
"...Have you been with more than two?!" She looks at me shocked, it seems I inadvertently gave myself away.
'It's probably the scent of Shiori and Nia because of the Beelzebub and having carried Nia.'
"I haven't been with women, sister, it's just that a sequence of things happened, but precisely, I only helped some girls who weren't doing well, you don't need to worry too much about it."
"...Okay...I'll believe you didn't have anything serious with that blue-haired girl who's in the same class as you and practically walks around like a needy bitch near you," She says, insulting Shiori.
'Jealousy hit her hard...' I wonder if she'll try to kill Shiori, if she tries, I'll have problems. I need to remove the Qlipha from Mukuro soon, the biggest problem is that her soul is in it.
And separating the two will be difficult, and there may be a problem in putting this Qlipha in Shiori, like Shiori being possessed by Mukuro or something similar.
"Sister, let's go eat something together? But first, go take a shower and get rid of the smell of other girls, it would be horrible if that smell permeated the house like the irritating smell of that Gothic Lolita."
"...Okay..." I decide to give in and go take a shower. There's no point in arguing. I got a very good help today, having the Nibelcole and even the Beelzebub.
Which means that now I have 1 angel and two demon kings in my possession. Of course, the demon king Beelzebub is very limited and has been modified to not require affinity, but it's still a help.
