Dimensional Gap
In the Dimensional Gap, former home of Ophis, and the current home of Great Red, where water, plant, light, etc. Except air doesn't exist, two warriors clad in Crimson and Silver armour, are figthing. They're Issei Hyoudou Asmodeus, the Boosted Gear wielder, former Pawn of Rias Gremory, and thw current Asmodeus in his Cardinal Crimson Promotion, and Vali Lucifer, the decesdant of the original Lucifer, and the wielder of Divine Dividing in his Empireo Juggernaut Drive.
Their fight are prety intense, keep hiting each other with their fist and their kick, and keep blasting each other with their magic.
[Boost! X7] the sound of the Boosted Gear rang througth out the empty space and give Issei a power up of his original strength, while he ducked under Vali's spin kick and deliver a powerful uppercut to Vali's chin and then kneeing his abdoment, but at the same time, Vali's hand grab Issei's shoulder and then the sound of [Divide! x5] from his Divine Dividing reached up to Issei's ear and weakened his power, and before he knows, Vali headbutting him and made a white orb from his norse magic explode in front of his face, and making him launch 15 feet of his original place.
Not going to give up, Issei charge up a crimson orb until the size of basket ball and punch the orb with his Boosted Gear and yelled "Super Dragon Shot!" then, the orb become some sort of a big energy wave that can destroy the entire city to Vali. Vali, trying to dodge the attack by launch himself to the left side, but sadly, he is too late to dodge it and his rigth side body is caught on the energy wave, destroying his armour, and leaving a burn mark on his entire rigth side.
"Not bad Issei, but you know you must take more energy than that to defeat me" Vali said while his armour start reforming.
"Say what you want Vali, but I will win this battle, then return to my harem, and have a great nigth together, no matter what" Yelled Issei.
[Hmph, as I expected from my partner, while pervert, he is awfully strong. Seems like this is going to be very interesting, don't you agree, Albion?] The voice from inside his Sacred Gear said.
[Yes, I agree Ddraig] Albion said, from inside Divine Dividing to Ddraig, the dragon that sealed in Boosted Gear.
The two Longinus bearrer launching their body at each other, and punch each other straigth to the face.
"Guh! Take this!" Vali yelled as he delivering a heel kick at Issei's face.
"Not gonna happen!" Issei caugth his leg and then head-buttiing Vali's head.
"That for what you did to me a minute ago, and this-" Issei deliver a point blank dragon shot at Vali's face, launching him 12 feet from his original position. "-is because you annoyed me" Issei said.
"Damn you!" Recovering from the last attack, Vali send his uppercut to Issei's chin, make the current Asmodeus flying upward, and the Descendant of the Lucifer launch himself until he is bellow the Bossted Gear wielder body, and kick his abdoment. Not statisfied with that, the Divine Dividing wielder fly upward and then go downward like a rocket and send Issei a crushing palm fist to his back side.
"Argh!" 'Shit! I need power up!' As if can hear Issei's mind, the sound of [Boost! X10] from Boosted Gear roaring up and give him a power ups 'O-kay, here is it!' Issei send a power of destruction from his 'mouth' and send the devastating black orb at Vali. Seeing this, vali try ti block the power of destruction with his norse magic, but the power of destruction breaking his guard, and hit Vali's body. "Not done yet!" Yell Issei while he is teleporting next to Vali while kicking his back side, swing his claw to Vali's face, and send a devastating fist to his abdoment.
"Gurgh!" Vali stumbled bacwards "No, I'm not going to lose!" Vali choke Issei whit his rigth hands while the sound of [Divide] countinued to be heard and weakening him, then Vali send a fist that continuosly hit Issei's face with his left hand, and then finishing it with an axe kick to Issei's head.
"Ahh... shit..." Issei try to recover from Vali's attack "Ddraig.. another boost!" Issei Yelled.
[Wait a sec] Ddraig said, theb the sound of [Boost X30] from his boosted gear can be heard.
"Okay, take this Vali!" Issei give Vali a devastating fist to the gut, but Vali dodge it by spinning to Issei's left and send Issei a heel kick that blocked by Issei's spin kick, try to counter attack, Issei send another devastating punch to Vali's abdoment, but blocked by Vali's hand.
Issei and Vali continuosly send a barrage of fist and kick that coated with magical energy, and power of destruction, while either blocking and dodging each other hit, and the sound of [Divide] and [Boost] keep repeating and try to following up to their speed, while their armour continue to destroyed and refromed.
They're finish the session of barrage punch and kick after a god-knows-how long with a head butt and then go backward to keep a distance.
"HAHAHAHA! That's good Issei! But still not enough!" Vali said then a magic circle appear in fron of Vali VIA Norse Magic, and an explosion white orb shot ou from it
"Damn!" Issei cursed and drew his left handed fist backward and then trust it forward, a crimson fist-like magic energy shot out from Issei's left hand and colide with Vali's norse magic, making a nuke-like explosion. Vali contionue firing his norse magic while Issei continue to firing his fist-like energy.
Neither of them want to lose, they keep firing their long ranged attack, until Issei shot his 'Dual Dragon Shot' a variaton of Dragon Shot, instead of using one of his fist, he use both of them, thus making it bigger and split into two. The attack hit Vali's rigth chest and rigth shin, and made him launch 15 metres from his original position
"*Pant* *Pant* Y-your doing great Issei" Said Vali with a little (Read: A lot) amount of glee in his word while catching his breath.
"*Pant* *Pant* *Gasp* *Pant* Your the one to talk" Issei said while also, catching his breath.
"*Pant* How about *Gasp* we end it here?" Vali says while the orb on his chest glowing brigthly.
"*Pant* Agree" Issei said while the orb on his entire body glowing brigthly too.
"Heaaaaah!" "Haaaa!"
Their keep charging a magical energy to their chest (or in Issei's case, charging to all his orb and then send all the charging up energy to his chest).
"Doryaaa!" "Oraaaa!"
[Longinus Smasher!]
The chesplate on each other armour are slides open and fire a powerful shot, and clashing at each other.
[Boost! X50]
[Divide! X46]
The energy wave of crimson and silver are trying to push each other while of their Sacred Gear keep repeating the sound of [Boost!] and [Divide!] and try to dominate each other energy.
Unoticed to them, because the powerful energy clashing at each other a black hole-like dimensional rift are opened bellow them, and sucking on them albeit slowly.
Neither of them noticed this but when they noticed half of their body already sucked into it.
"Wha-what's going on?!" Yelled Issei while his body, slowly sucked to the black hole.
"Shit! It seems like our energy clash are opened the dimensional rift!" Yelled Vali, that slowly sucked to the black hole too.
"What?! Bu-but, what it means?!"
"That means, if we compleatly sucked to this thing, we can come to another timeline or worse, another dimension!"
"Is there anything we can do?!"
"Nope"
"Well, fuck, I can't feel my girls breast again" Issei said before his and Vali's body are compleately sucked to the black hole.
Asmodeus Mansion
In the Asmodeus Mansion, a women, that looked like she is in her mid twenties, while the reality Rias Gremory Asmodeus, former head of the Gremory family, and Issei Hyoudou Asmodeus' first wife are in her mid fourty, playing chess with their 3rd and youngest son, Draco Hyoudou Asmodeus a twelve years old boy with brown hair and greenish blue eyes, while watching their first and second son and daughter are sparing outside. The first son is a twenty-one years old boy with short red hair and brown eyes named Akaito Gremory Asmodeus, the current head of the Gremory clan, and a seventeen years old girl with a Crimson hair that goes down to her butt and big brown eyes named Scarlet Hyoudou Asmodeus. They married after Issei and Vali figth for the 66 times, and after Issei promoted to become the Ultimate-Class devil, and become the current Asmodeus, while Falbium change his possition to Belphegor. And because he is naturally lazy, that title suits him more than anything. Suddenly, she have a bad feeling for Issei.
'What is this feeling? It's like Ise-kun is doesn't exist in this world anymore... does that mean.. he's dead?! No, no, Issei can't be die easely, but stil... what is this feeling?' Rias though.
"Mama? Why are you spacing out?" the youngest son of the former Gremory head said.
"It's nothing dear, just thinking about your father" Rias said reasurely with a beautiful smile on her face.
"Don't worry Mama, Papa is strong, he can't be beaten by Vali Jii-san!" Draco said excitedly.
"Yeah, Dad will be not beaten easely, but the chance of him being lose is stil exist, even if it is 0.1%" Akaito said.
"Don't say that Akai-Nii, Dady is strong, so the chance of Vali-Jii is winning are reduced to 0%!" The second children in the family said.
"Nope, 0% is impossible to exist" Akaito said.
"Of course it is! Father always thaught us that nothing is impossible!" Scarlet said.
"Ufufufu, cut it out you two, we know that your father will win now don't we?" Rias said.
"Yes/Of course/Uh-huh" The three of them said while nodding their head.
Rias let a soft giggle escaped from her lips while she is looking up to the sky and though.
'still... what is that feeling?'.
Mahora Academy-Dean office
Konoemon Konoe, the Dean of mahora academy, an almost bald old man with a thick brows and long beard sighed, he doesn't think that become a headmaster is the same like become a governor, or at least, what is like to be a governor. Because, the two of the job has one thing similiar, and that is papper work. Papper work, the incarnation of all evil in this world. 'Why am I doing this again? Ah yes, to ensue that nothing will happen with Eva and The World Tree, and also to prove my leadership of Kanto Magic Association' He though. Suddenly, he felt a strong magic energy eminating from The World Tree. Calling a few teacher that aware of the existence of magic, he ran to The World Tree.
Mahora Academy-The World Tree
Konoemon and a few teacher wacth as the word tree glowing brigthly, and then a blinding light shot out to the sky, throught out the clouds. They watched until the light dies down and from the sky, two figures falling to the earth, one clad in crimson armour, and the other one clad in silver armour, the armour is resembling that of dragon, but at the same time, it was not. "Who is this two?" a man, with glasses and spiky white hair said.
"Hell if I know, or rather, hell if WE are know" Said one of the teacher.
"Look! Their moving!".
Truth to be told, that they are moving and groaning. The one in silver is looking to each teacher warily, while the one in crimson, is shaking his head, as if try to overcome a terrible headache.
"Wh-who are y-you?" the in silver said weakly, and from the voice, he is a man.
"Well, WHO are you, young man?" The Dean of Mahora Academy said.
"My name is-" Not finishied from his speech, the armour around him vanishes, leaving a white dragon wing and a man in his NIneteenth with silver hair, and ragged clothes can be seen. And of course, becasue the clothes are ragged, they can see a six pack body with a full body bruise, a burn mark on his entire right side. The armour of the crimson one is also vanishes, leaving a red gauntlet with many spikes and a man in his eighteenth, with a brown hair also with tattered clothes that seemed like school uniform, showing his eight pack and like the former one, a full body bruise and a burn mark, not in his rigth side, but on his face down to his chest.
"Ddraig, what happened? Why our armour are vanishes?" The brunnete said to his gauntlet.
Before all of the teacher questioned his sanity, a voice, from the brunette gauntlet said [It seems that the dimensional rift are sucking out our energy, and that also means, YOU and VALI'S energy].
"Is that true, Albion?" The silver head said.
[Yes, it's true, me and Ddraig are only on our 20% while you and Issei are only on 35%] a voice from the white dragon wing said.
"When do you think we can fully came back to our 100%?" The one named Vali said.
[At best, one and half month for me and Ddraig, and four weeks for you and Issei] Albion said.
"Damn, we are use to much energy from our last attack" Issei said.
[True] Ddraig said.
Overcoming his confusion, the Dean ask "So, WHO are you two?".
"Ah, sorry, my name is Issei Hyoudou Asmodeus, and this is-" "Vali, Vali Lucifer".
"Ah, then welcome to Mahora Academy" Konoemon Said.
"Mahora Academy?" Ask Issei.
"Yes Issei-San, this entire city is Mahora Academy, and my name is Konoemon Konoe, the Dean of this academy" Konoemon said while spreading his arm.
"Where exactly are we, Konoemon Konoe?" Ask Vali.
"Why, in Japan of course" Konoemon said.
'Weird, I don't even know that an academy that include a city like this Mahora exist' Issei though.
[Remember partner, we are sucked to the dimensional rift, so maybe, we are in Japan in another universe] Ddraig said interupting Issei's though.
'Well, you may be rigth' Issei said telepathically.
'So, we are in Japan, but maybe, this is a parallel universe of our own world, don't you think so, Albion?' ask Vali
[Yes, that's true, but still, what are you gonna do?] Albion ask
'I don't know' Vali said to Albion
"Looks like, you don't have a place to stay, so how about stay in here? But of course it's not free" Konoemon said.
"What do you want?" Issei said.
"I want you... to become a teacher here" Konoemon said.
"Huh?" Issei and Vali said at the same time questioningly.
And then, the wonderful adventure of Issei and Vali are begin.
