Disclaimer: I don't own Highschool DxD or any of its characters featured in this chapter.

Without further ado enjoy the story.

The Dimensional Gap and endless void where nothing exists; there is no water, air, land, not even light. Pure nothingness shrouded in darkness; no life exist except for two beings the Ouroboros Dragon, Orphis and The Dragon of Dragons, Great Red. But at this moment, in the vast void a battle rages between two warriors, one in red armor, the other in white. That's right they are Issei Hyoduou, and Vali Lucifer, weilders of the Longinus Class Sacred Gears, Boosted Gear, and Divine Dividing respectably.

Years have passed since Issei become the ultimate pawn, and lead his beloved Rias and her team into the top ten in rating games. He finally achieved his dream of being a harem king. Life was good for him until one day Vali reappear after vanishing without a trace for so many years. He challenges Issei to a final match to see who the ultimate warrior is once and for all. And so this is where our story begins…

As the fight rages on, it seems to be an even match. Neither one of them was giving their opponent an opening as fist collided against fist they continued to counter until.

[DIVIDE! X5] Vali backs off from Issei to try to weaken him, with a blast of energy from his sacred gear, before landing another hit.

Issei then shouts.

"You're going to have to do better than that Vali if you want to land a hit!" As he effortlessly dodges Vali's attack.

"Damn it!" cried Vali.

"Take this!" [BOOST!] Yelled by Issei as he charged straight for Vali.

Vali quickly moves out of the way of the attack but then Issei shouts out.

[Mode Change! Welsh Sonic Boost Knight] [BOOST! X10] In an instant Issei vanishes from Vali's sight. Using his Godspeed to out maneuver Vali, Issei reappears from behind and changes again.

[Mode Change! Welsh Dragonic Rook] [BOOST! X10] Vali turns around to try and defend from it, but it fails as Issei lands a direct hit into his chest.

Vali cries in pain as he felt the force of a powerful punch.

"Not bad Issei, so this is the power you obtain from fighting The Hero Faction. I always wanted to fight you using that form, But it won't be enough for you to win!" suddenly Vali begins to start a chant and hundreds of orbs made of energy surrounded him.

"Are you kidding me, he had that much magic ability still in him to use, he really is a battle maniac!" as Issei was thinking and panicking on what to do another voice in his head appeared

(Calm down, and get a hold of yourself Issei.) Said Ddraig

"Ddriag! How can I calm down when he still has more fight left in him than me!" Cried Issei.

(Issei you may have fought Vali a few times before but you never fought like this, you never knew his full strength but neither has he known our full strength either. All we can do is dodge and worn out his magic before going back on the offensive.) Replied Ddraig

"You're right Ddriag looks like we're going to have to play defensive, and drag this out to win. Sigh. Why did I have to agree on fighting in this match and the dimensional gap of all places." Said Issei

(It's your fault, you idiot, he taunted you and pissed you off to the point that you wanted to fight him. So don't even complain!) Yelled Ddraig

Thinking back to all the things that have to transpire to this battle, Issei sighs in in defeat as he knew Ddraig was right. Before Issei could continue his conversation, Vali interrupts with his magic barrage.

"This is your end Issei! Farwell!" With the turn of his wrist, Vali unleashed them upon Issei.

Before Issei can even switch to his Knight form, the attack hits him from all directions with no way out. As the barrage continues Issei begins to feel faint, the attack has destroyed almost half of the armor.

"Is this the end? Is this all I can do against Vali? No… What am I thinking, I can't lose there are too many people that depend on me. Asia, Xenovia, Irinia, Koneko, Akeno… Even Kiba and Gasper. They depend on me, and I rely on them I have to win this. I have to come back alive to them… to Rias!"

Even though with all his effort, Issei's body wouldn't move. The attack has ended. Issei's body is so bruised and battered, his armor was almost entirely gone, except for the boosted gear on his left hand, it's hard to tell that he is even alive. Vali then grips Issei by his neck preparing to finish him off. Until Issei's left arm moves. Gathering a small bit of his magic; he fires straight at Vali's face

[DRAGON SHOT] [BOOST! X5] in that instant Vali lets go of Issei and backs away.

Then at the top of his lungs, Issei cried out

"I, the one to awaken,"

"Am the Sekiryuutei who holds up the truth of the King up high!"

"Holding the Infinite Hope and the Indestructible dream and walking the road of righteousness."

"I will become the Emperor of the Crimson Dragon."

"And I will lead you to the path of Heaven glowing in True-Crimson light!"

[Cardinal Crimson Full Drive!]

A crimson aura envelopes Issei and recreates his destroyed armor, and color it crimson.

"So this is the form you obtained the True-Queen your answer that supposedly surpasses Juggernaut Drive. Well then let's see if it can defeat my Juggernaut Drive, one that is not clouded by my predecessors."

And with that Vali began his chant

"I, the one to awaken,"

"Am the Hakuryuukou who has taken the principles of supremacy!"

"I envy the Infinite and I pursue the Dream."

"I shall become the White Dragon of domination."

"And I shall take you to the limits of the White Paradise"

[Juggernaut Over Drive!]

[Empireo Juggernaut Over Drive!] "It is similar, but different to Juggernaut Drive. An enhanced form which only I can use. You shall taste this strength with your body!" Exclaimed Vali

"Like I would let that happen!" cried Issei, as he charges at Vali. [Star Sonic Booster!] In an instant Issei disappears again.

"It futile." States Vali as he suddenly began moving at the same speed as Issei.

"Damn it I need to go faster!" [BOOST! X15] Issei now had the upper hand, he ready his fist at Vali.

[Solid Impact Booster!] As Issei landed his hit, Vali counter him and landed a blow to Issei's face, they sent each other flying in opposite directions. As Issei was trying to regain his posture, Vali spoke.

"Well this fight has been enjoyable for the past two days, but it's time I end this. The Orb on Vali's Chest plate began to glow.

Suddenly Ddraig's Voice rang out in Issei's mind.

(Issei! Charge the Fang Blast Booster, as much as you can, right now! Vali is going to use his Longinus Smasher!) Yelled Ddraig

At the words of Ddraig, Issei began to focus as hard he could on storing and compressing as much energy as he could into the cannons.

" Shit, why hadn't I realized sooner! I got to boost the cannons as much as I can, or I'm done for!" Exclaimed Issei.

[BOOST! X10]

"This isn't enough I got to boost even more than I've ever done! Ddraig how much longer until Vali can full charge that attack?" Asked Issei.

(At the rate he's going another twenty seconds and he's done you're going to need to perform two boosts every sec until he fires, to counter it!) Replied Ddraig.

"Can I even do that!?" Asked Issei, questioning Ddraig's statement

(Of course you can the chances making it in time are slim, but with your new body given to you by Great Red you'll be able to handle it.) Said Ddraig confidently.

"If you say so Ddraig, I believe in you partner, Here we go!"

[BOOST! X40]

(That's it Issei you reach the amount we need with 4 seconds to spare keep it up.)

"In that case, I'll try for at least ten more!"

[BOOST! X13]

"Even with all that boosting Issei, It will never be enough this is your end!" Yelled Vali

"Like Hell it will. I'm going to make this out alive no matter what!" Replied Issei

[LONGINUS SMASHER!][FANG BLAST BOOSTER!]

As both of them fired their attacks simultaneously, the attacks collided, neither one giving the other a chance to succeeded until suddenly, the energy of Vali's Longinus Smasher gives way to the Fang Blast Booster in an instant, and a massive explosion erupts enveloping the two in a brilliant white light.

As the light subsides, Issei opens his eyes and can only stare in awe as what he sees before him is something he has never seen before, and shouldn't exist in the Dimensional Gap.

"Ddraig what is that?" says Issei out loud.

(What you mean the portal? That Issei is a Chronos-Nexus Gate.)

"A Chronos-Nexus Gate? What caused this to appear all of a sudden?" asked Issei.

"That would be us Issei; we're the ones that made it appear." Issei turns around in surprise by the voice of Vali, only to be in shock as Vali has lost his right arm completely and a small part of the right side of his body is burnt to a crisp.

"Vali…. What the hell… happen to you…." States a nearly speechless Issei.

"You did this, or rather your attack prevailed and defeated mine. But that's not the point now; right now our problem is this gate. When our attacks collided the energy, it unleashed rip the fabric of space in time in this area. In normal circumstances, this would be an easy fix. However because we're in the Dimensional Gap, the laws of time and space do not apply here, they're distorted. There is only one way to fix this, and that is to send one us through the gate and alter history."

Before Vali explains anymore, Issei replies.

"But how and why are we going to just alter history to get rid of this thing?"

Before Vali could utter another word, Albion speaks up.

[This gate we created is much larger than a regular Chronos-Nexus gate. Once these gates reach a certain size, they begin to act like a black hole that destroys time and space. The only way to close it is to send one of the people responsible for its creation and erase the others from existence. The result is that the gate was never created. Therefore the fabric of time and space is restored.]

"I see, so that's how it is, wait a sec that means one of us will have to kill the other!" Exclaimed Issei.

"That's right Issei; you're going to have to erase my existence." Vali states this calmly.

"What why are tell me to do it? I mean sure I don't want to die just yet, but neither do you there's got to be a reason as to why you're telling me to kill you." Said Issei, confused by Vali's statement

That's when Ddraig explains

(When you're inside the gate you're required to be almost at full strength to alter history, in Vali's state, he won't survive the alteration which is why you have to do it. But when you erase a person you also absorb some of their traits whether it is physically or mentally; however the good thing about this is that you can choose a few traits, the rest are random and rely all on luck in getting them.)

" I see, hopefully, I don't get any of Vali's bad traits." Said Issei sarcastically

"Hey, I heard that!" shouted Vali in response to Issei's insult.

"Easy Vali, I'm just joking anyway, I'm ready, let's fix this problem quickly." Says a resolved Issei

"Very well, but Issei before you go come here." As for Issei approach Vali closer, he notices that parts of his right side was disintegrating.

"Vali… you're…" Before Issei could say anything else, Vali interrupted him.

"I know Issei; the Dimensional Gap is turning me into a part of it, which is why I need to do one thing before I die, please give me your right hand."

As instructed by Vali, Issei gave his right hand. Issei felt a surge of energy follow through his body, and suddenly the armor on his right arm turned white, and silver wings appeared on his back.

"Vali… what did you…"

"I learned a forbidden spell that can transfer ownership of Sacred Gears. I'm leaving Albion and the Divine Dividing in your care. Sacred Gears can't be transferred to a person who uses the gate to erase the current owner; it was a defensive system that God had installed as a precaution if the gates were misused. Anyway when you travel to time you'll awake at a point were never had your current powers, you won't have meet Rias or the others yet. For all, I know you might have to relive your childhood. But that's a good thing cause Albion will be with you the whole time training you to master my Sacred Gear and maybe help you be less of a pervert and an idiot." Said Vali

"Well sorry for a being a perverted power idiot." Issei states this loudly while feeling a bit depress from the remark.

"Sorry I couldn't help saying it, I mean even I'm embarrassed at times that my Eternal Rival is a weirdo. Anyway, Ddraig will be asleep like before, and when he awakens he'll remember everything that has transpired up to this point before going through the gate. You'll be able to change yourself for the better and the outcome of certain events in your life with the knowledge you'll possess. So promise me one thing before you leave, make sure you make it a world far better than this one."

After hearing Vali's dying wish, Issei hesitates for a moment until he begins to speak.

"I promise, to you my Eternal Rival, even if you don't exist in the next world, there won't be an opponent as strong as you, I will never forget you." Says Issei proudly.

"I'm glad to hear that, now go and farewell Issei."

And with that Issei jump into the portal. On the other side, there was nothing a vast white void filled with clock gears and images of all sorts of events and people. "Amazing there so many things but how do we find Vali's?"

((Just concentrate and think of him… Hey, I'm talking to… him… STOP COPYING ME!))

"Both of you stop this arguing and figure out which one of you will do the explaining. You guys are starting to give me a headache."

( … ) There was a long moment of silence before Albion began to speak.

[Issei it's me Albion after talking to Ddraig and explaining that he will soon be asleep again we have agreed that I will be the only one guiding you through on how to use the gate since both of us need to get to know each other better.]

"That seems fair, very well I'm counting on you Albion so how do we find Vali." Asked Issei

[That's quite simple just think of him, and the system will then bring out the panel that has his existence.] Said Albion as he gave his explanation.

"Easy enough let's get to work." Issei began to think of his rival's face and attitude, and sure enough, his panel appeared.

"Wow, this explains everything about him from his age, his interests, even names of the parents that abandoned him.

[Issei quit reading about Vali's life and his secrets and let's just get this over. I can't hold onto the resolve I have of losing, possibly the best host and friend I ever had.]

"That's right I almost forgot it must be hard on Albion being separated from Vali. I gotta make this quick."

"Alright let's see how we have to erase him." Said Issei as he tries to get adjusted to the system.

Suddenly another panel appears and shows the traits that will be transferred to Issei when Vali is erased. "Let's see here increase, in stamina, physical strength, and intelligence, as well as being Vali's age and slightly better looks. I like this already, and I don't need to change anything. Wait a sec, Vali's age… he's the same as Rias and Akeno…?!" Issei stops and thinks for a few seconds then suddenly jumps with joy

"Alright! I'll be in the same class as Rias and Akeno; I'm going to love this new life!"

As Issei states this, he begins to think of perverted thoughts of all the things he could do with them since he'll be with them for an extra year.

[Issei stop with those perverted thoughts right now and stay focus, you can think about that stuff when you're actually with them again for now you try to not do or think of these things.]

"Oh come on Albion just a bit won't hurt."

[Do you want me to hit you right now.]

"Pfft as if you can hit…." Before Issei could even finish his sentence, his right arm began to move on its own, and punch him in the face.

"Oww! What the hell! Albion how did you do that?"

[Because You're my host I can take over one of your body parts temporary, looks like Ddraig never used it on you, guess he was being soft on you. If you disobey me again about the perverted stuff I will do it again do I make myself clear?]

"Yes, I understand." Says a displeased Issei.

[Good, now according to this panel it seems that you'll be sent back in time to when you were in Grade One.]

"So, I'm gonna relive my life from the age of seven, not to mention I'm born one year earlier than all the people I knew from before. Wait, I need to pull up Akeno's panel."

[What for?] Another panel appears this time detailing all about Akeno.

"Here it is when Akeno was a child she lived in a shrine just outside of my town before she met Rias. My plan is this since I'm going to encounter them, differently, I need some way to smooth that process. In this case, I'll become Akeno's Childhood friend, when she returns to the human world with Rias, she'll remember me. Hopefully, she and Rias will notice that I have a Sacred Gear right away and try to recruit me into Rias's peerage."

After listening to Issei's reasoning, Albion remained silent for a moment and then replied.

[That's is a good plan. That would mean you'll get your evil pieces sooner and bring you back almost to full strength, before the recruitment of the other half of Rias's group.]

"Exactly the sooner, the better."

[Alright but that means you're going to have to join some sort of sports club to get your physical body in shape until then, that way we can be sure, you can use Balance Breaker.]

"Alright sounds like everything is set shall I begin the reset?" Asked Issei as he finished all of his preparations.

[Yes, let's begin.] Replied Albion, not wanting to waste any more time.

And so, the world was reset. The Chronos-Nexus Gate created by Issei and Vali, began to shrink, as Vali watched on waiting for Issei's success. Suddenly a wave of energy is unleashed from the gate, and in an instant, Vali is no more. The wave continues to spread resetting the whole world, even Heaven and the Underworld were affected. But this is not where our story ends. This is just the beginning; the Celestial Rebirth has only just begun.
