Y/n Pov:

Seeing a woman so beautiful, she seems to surpass Jet in terms of sheer beauty. When she looks at us her power was flaring like crazy. She attacks us I feel like her power alone can take us all on at once and not even break a sweat. She kicks me in the gut sending me flying towards the cave wall, she broke my back just by a kick. And I even used magic to soften the blow. So that force alone can kill anyone if they are not ready. Good thing I was able to read the room if I did not, I might have died to her on the spot, she attacks Rossweisse next, but she was able to block the attack, this woman named Crimson can really hold her own against us with ease. Akeno used a powerful lighting strike on Crimson but swats it to the top of the cave, she can do all of this with ease this is crazy power I sense. I summoned Jet to heal me up and she was able to heal me up pretty quick and so I went back into the fight using my earth magic we attack each other but she had power over me. She was easily able to overpower my earth magic with ease. Is this what SG warned me about.

Crimson: " My power is to steal and every time you clash with me in any means, in both magic and physical aspect. I grow stronger, making my power increase even higher than normal, and this is still me holding back."

So that is her power she must have a passive skill she is abnormally stronger than Issei's boosted gear. That's when SG talked to me in my mind.

Sg: "*Y/n if this fight goes any longer, she will become powerful enough to one tap us not even me and Jet can protect you from that. Her passive skill is called the crimson field for as long as there are any types of battle like the one right now, she gains more power and if this goes on you won't be strong enough to beat the Mad God. *" I nod and talk to Jet for help and told her to release one spirit into me.

Jet: "* Y/n you know I can't allow such an action you remembered what I said? *"

Y/n: "*I do, and I don't care Jet what if we did exchange. *"

Jet: "* What kind are we talking about? *"

Y/n: "* First I need to know if we are to do this exchange what would you recommend for me? *"

Akeno Pov:

I was strike bolt after blot to beat this woman this is just getting stronger by the seconded, she does not even deflect the bolts anymore. Which only means she does not see me as a threat anymore.

She was about to attack Rossweisse when all of see Y/n screaming in pain. As her power grew enough to help us. What did she do?

Y/n Pov:

I am grabbing my chest out of pain. I could not breathe so this is what it is like to add this kind of power. 

Jet: "* You're a foolish host you know. *" I know but if it means helping this woman out form this corruption then so let it be. I went to attack Crimson and she was ready to kill me when, she got hit in the gut by earth magic sending her flying towards the cave wall. 

Y/n: "Rossweisse give me support Akeno I want you to make a powerful bolt of lightning and where to strike at." They nod, me and Rossweisse went to attack Crimson who was getting out of the rumble, and I can sense Akeno's lighting magic going crazy this is our only shot. Rossweisse sends a ray of magical attacks at Crimson who did steal the power from. But she did not see that she was hit by something new that I did with Jet I used old magic, magic that can rival her own. She told me that old magic can counter against this kind of magic, due to it not ever being stolen by any means. So, she could not beat old magic, I cut my hand and a clone of myself comes out and attacks with me attacking Crimson by using a bit of my blood and adding my own magical life energy into that spell it was able to fight, Crimson and we did work together, and, in any time, Crimson was to steal magic she can only steal Rossweisse, which takes about a second to steal which means we got enough time to use, that as cover.

My blood self goes in full speed as Crimson used her magic now to show she sees us as a threat she used her own blade and cuts the ground under us, but due to my old magic and earth I reshape the ground under us, I threw Jet at her she was caught off guard by this sudden spear throw. She was able to deflect Jet, but she saw my blood self-coming in in the last moment and got punched and she starts to use a blood spear. She hits in her the stomach with the hilt at the end. And did a full 360 degree hitting the ribs of Crimson and used her leg to make her fall over on the ground and starts to try and price her, she rolls from each spear attack, but it was not easy sense. She even got a scratch pissing her off. She cuts down the blood self, but thanks to my old magic I used the blood pool as a way to teleport between headbutting her, breaking her noise. She was even more pissed then ever and her blade reaches for the sky as a red moon, and everything comes to fall apart.

We were in like a different plane of exist, the sky was red the moon was here, but it was also red. But then in that moment I put my fingers onto my spear and casted a spell as a dark purple and green go around my spear I look at her one last time.

Crimson: "You sure are strong using old magic. But I'm going to end this fight." I saw her point her blade at me, as she slashed a crimson energy at me Rossweisse used a protective spell over me countering most of the damage. But that did not mean that, the aftershock did a number on my insides it was that I was bleeding badly. Even if the attack itself was blocked it has something to do with this plane of exist. I was trying figure out how she did that when, a thought came to me. Did she rewrite probability itself? No wonder why my insides feel like a soup. But Jet was able to stop some of it, thanks to her healing regeneration. "In this very plain where I was sealed away to is my new home. I have a few tricks and you might guess one of them. But that is not even my strongest yet."

I threw my spear at her adding the remaining magic I had left over; I did not like her talking and besides Akeno is ready Crimson dodged to the left but thanks to old magic there is something I can do as well with is Causality manipulation, she did not see it coming she was able to block the spear attack but thanks to my ability to manipulate causality I was able to go to the power of warping logic itself stabbing her stomach. She could not react in time a massive lightning bolt coming towards her.

Y/n: "NOW AKENO." Using Jet as a light rod and sense the spear is in Crimson's body it will deal enough damage to rip her insides from within. And in that moment Crimson was hit by the powerful lightning bolt.

A bit ago:

Jet: "* Y/n once this spirit goes into by force you will gain all of that spirits knowledge. But what do you have to offer to me sense you want to use this spirits power so badly? *" 

Y/n: "* 2 years of my life. *"

Jet: "* Sorry Y/n I really like you a lot, but that deal won't go for me. And besides I don't won't you wasting your years off of this. *"

Y/n: "* Jet I understand but I won't have a life if I die here but I will increase the years this time 5. *" I can hear Jet getting mad, but she snaps her fingers and a spirt comes into my body giving me all the knowledge to use old magic.

Now:

5 years not bad I guess I don't know when I might die but even so now I can use old magic which in itself is a powerful ability to use I was able to gain all of that knowledge, but it seems that was only scratching the surface of this powerful magic. For even the old magic user was able to reach that state but with that type of magic I can beat him the Mad God. And if I get Crimson onto our side and purify her, she should be good. I took the blade away from her as I did the plane, we were in is now falling apart. I summon SG and cut my hand and thanks to that I was able to add my blood to crimson blade, and sense that blade was corrupted I was with able to save her. Her body did fade into the blade. Meaning she was saved.

Y/n: "Now what SG."

SG: "Well at the moment you seem to need to get new power. Because your friends are fighting Trevor so I will send your friends here to them because thanks to the punk thinking he is all high and mighty we are able to send Akeno and Rossweisse. But for now, you will be sent to a different plane of exist where you will need to train for some time." I nod but it seems Akeno wants to come with me. But Rias and the others need all the help they need to beat that man I hate so much. So, in a moment SG teleports them back to Rias and I was in a different realm to say.

Sg: "This plane will help you face powerful foes thanks to its ability to make foes stronger than you, so be ready to face foes just as strong as us gods if not stronger. Some of them will be on fair level of the Mad God, and the reason why we don't use this plane to face the Mad God is because if he was to find out, he would have taken it as his own. And made millions of monsters. But now get ready Y/n for your first task is to face that. And don't worry the plane is alive so it won't kill you."

Y/n: "What the hell is that?"

Jet: "The first animal to ever exist called the beast of all races. Very powerful so get ready to face the very first animal to ever live a long time ago, and also dear that creature will not be affected by magic so easily. So be ready for a one hell of a fight." I nod and the beast now spots me and comes at me full force.

(Well, a bit of a short chapter lots of action pact, and yes you can learn some powerful skills from Jet and some useful knowledge from Sg I think you guys are starting to understand the whole thing now huh. Anyways tell me wat u guys think and all anyways omage1 out peace.)
