A few days ago Vali was shocked to hear that Azazel knew about what she was trying to do and actually let her do as she pleased. Though the most shocking thing the one she been trying to find was actually living with her soon be rival the red dragon emperor.
It didn't stopped there as she later found out about the two dragon gods are the mate of this person. She was pleased that this person is strong enough to make the strongest being to fall for this person.
She's dying to know and fight him. Now when she arrive with her group found the beautiful mature woman with long scarlet braided hair. Instantly her sacred gear spoke in shock.
"Ara~ if it isn't albino. Its always unpleasant to see you."
[How did you gain back your body!?]
"That would be my mate. He helped gain back my body. Perhaps if you offer yourself to him then he'll give you back your body."
Irene teasingly said which made albino annoyed that her eternal rival were suggesting something. Though she was interested in this mate of her but was shocked to feel almost nothing from Issei. Literary nothing like an endless abyss devoid of power.
Issei was suppressing his power constantly which cause him to better control it. If he were to stopped then it would released an aura that cause everyone to suffocate. He was regaining back his power which includes Irene domination.
"I think we should introduce ourself, Vali. Greetings my name is Arthur Pendragon."
"Nice to meet you, I'm Le fay, le fay Pendragon!"
"Yo the name's Bikou!"
"Hello nya~ my name is Kuroka, nice to meet you."
"I'm Vali Lucifer and I want to have spar with you to see what the mate of two dragon god to offer."
"Jeez I already know is going to happened."
"Hold on, before you fight my Issei I want a to do a little wager."
"Hmph what is it?"
"If you lose then both you and albino would become my Issei to be his mate while if you win then I'll let Issei revive Albino."
Irene offer Issei to wonder what she's planning to do. If his correct then she's planning to do the same in the past timeline where two of them suck Issei dry. Albino felt something about her offer but tempted to gain a body and wonder if becoming her rival's mate to be hers.
"Nya~ can I join that offer? Having red dragon as my mate would give me strong children."
"Wait aren't you too straight forward? Actually before we have spar I want to tell you guys about me."
Issei then did the same explanation as his friends from ORC which surprise them but the most affected was Kuroka who cried knowing her little sister forgave her and Issei was trying to clear her name.
He approach her and offered a hugged which she accepted feeling a sense of familiarity with Issei. It cause her to create special scent for their mate. Issei was surprise but accepted it. Even if everything seem progressing too fast doesn't mind it.
Issei knew it was due to Big G doing something in helping him gain his lover back even if its only a small way. Asia was lucky enough to recall most of the past due to her connection to Big G.
"Wait your saying that you were my lover in the future huh? Well that seem about right but fight me first."
"Thank you for helping me, Issei."
"I would always do it even if you don't know me I'll always be there for you."
Kuroka teasingly smiled then did the unthinkable and bit Issei marking him as his mate which surprised Issei from the action. Her heart somehow knew it was the right thing to do. The instinct of her eternal mate was ringing ever since she saw Issei.
This is the same as Koneko but her constant refusal to use her Nekoshou side hinder it. However, now she would be in heat once Issei go back.
[A/N: this Is just my bullshit not in the cannon]
"I'll be first before my little sister nyah~"
"This peculiar but I dint feel anything strange despite it should. Perhaps it's a side affect of future vision."(Arthur)
"Me too but still it feel fun."
After few minutes, Kuroka calmed down while asking question about her sister which Issei happily told her but Vali interrupt them saying she want to have spar now. The spectator move far enough to not be affected by the aftershock. Azazel one of his gadget to have panel to watch them.
"Let me see how strong you are!"
"I recommend using balance breaker immediately if you want to win."
Irene remain close to watch the battle. Vali annoyed for being understatement but her instincts telling her it was the right chooses. She quickly use her scale mail armor enveloping every part of her body while radiating a powerful aura.
Issei remain stoic unfazed by the power that could easily rival an ultimate class or weaker super-class. He took a deep breath and took a stance not even planning to use his sacred gear. Vali saw this felt offended by his action.
"Why aren't you using your boosted gear? Don't tell me its gone after you revive, the red dragon emperor?"
"First of all, she has name and that is Irene. Second, no I still have my sacred gear. Lastly, it would result in an instant defeat if I do that."
Issei was annoyed when Irene is not called by her name making the latter smile. She was glad that Issei was getting mad on he behalf despite not minding it.
"Aren't you being overconfident?"
"Then…."
Both of them arrive in the mountain in mere seconds by Issei grabbing Vali face. She couldn't even have time to react from the attack but didn't waste time and use her divine divider to absorb Issei strength.
Vali increase her power then flew in the sky where both of them fought. They moving in tremendous speed faster than the speed of sound while their power collided a large force cause the nearby mountain quake.
[Divide!Divide!Divide!Divide!]
She was struggling to keep from Issei who seem have bottomless amount of energy. Vali had already been absorbing an absurd amount of energy from Issei but he didn't felt tried by one bit.
Those watching was surprise to see Vali getting serious to someone who hasn't even display any other power beside physical strength. Issei using his devil strength which provided by the True Maou bloodline.
"Amazing! As expected of my Eternal rival!"
"That soon to be mate."
"Only if you win!"
Vali took distance away from Issei who knew what she was planning to do. Everyone watch in anticipation from the ongoing battle.
"I cant beat you like this then I'll use use my juggernaut drive!"
"If that's the case I'll use my scale mail."
Issei proceeded to summon his boosted gear then increase his power in an alarming rate. He didn't even notice that his hair was starting to turn white.
[BOOST!BOOST!BOOST!BOOST!]
"I, who am about to awaken…"
[BOOST!BOOST!BOOST!BOOST!]
Both of them power up increasing tyeir power continously even causing the dimension to crack but thankfully ophis and Great red able to instantly repair it.
"Holy crap those two are really getting to it."
"My mate is really strong nya~"
"It's my first to see Vali use this technique."
"Those two are getting out of hand. *sigh* I wonder what kind of monster if those two have child."
"Azazel-sensei can you explain what's going on and who are this people?"
Murayama and the rest who just arrive from where they are watch the fight between the two heavenly dragon. Azazel gave them explanation while continuing to watch the fight.
"…Am the Heavenly Dragon who has taken the principles of supremacy from GodI envy the Infinite and I pursue the Dream….."
[BOOST!BOOST!BOOST!BOOST!]
"…I shall become the White Dragon of Supremacy and I shall take you to the limits of white paradise."
Both finish their power up causing everything nearby to be obliterate. From the smoke, stood the two of them with different form.
[WELSH DRAGON BALANCE BREAKER]
"Juggernaut drive!"
Then both stared at each other unmoving and for a moment everything felt stagnant but instantly massive explosion occurred from their collision.
