A Crusade trough the Multiverse

DxD

idk if 2,800 words are considered a "long" chapter but its definitely long in my book

=========

the very first thing (y/n) saw when he was teleported was none other then that famous scene from the anime "highschool DxD", otherwise known as a hentai trying to be an anime.

he saw that Raynare who was in her human form was about to kill issei, he wanted to jump in and save him but he stopped when he noticed that they were not moving at all. its like someone pushed the "pause" button and stopped the world itself.

[welcome to the world of Highschool DxD!]

said his system but this time it was both showing him flying words and talking to his head

[the timeline of this universe is going to be changed by the ??? and you were send here to make sure that the story is progressing as it should be.]

[first mission- save Issei!]

[description- ??? has put a barrier around the area, Rias will not be able to teleport and save Issei from death, protect the main protagonist from all danger]

[reward: {light spear}(modified to your silver eyes), {observe}, {random reward}]

[failure: Issei will die and Draig soul will be destroyed by ???]

light spear? like the one that the fallen angels use? damn thats a nice reward, and the fact that it will be modified so it would use the energy of his silver eyes is even better! the {observe} skill is good also, he will be able to judge his opponents and know the full effect of every item he has.

the random reward...well its pretty self explanatory

[time will resume in 5 sec, please get ready!]

he looked at Issei and then at Rayane who had her head lowered to hide her sadistic smirk, he kicked the ground and dashed at her, just as he was near her time started to move again

Raynare: i said, would you die for me-

(y/n): i shall smite thy in the name of the lord!

he saw the fallen angel making a confused face and turned her head in his direction, before his fist could make contact she managed to voice her confusion.

Raynare: what the fu-

well almost...

the punch send her in the air, but she never fell to the ground, as she transformed into her fallen angel form. she looked down, fury clear in her eyes, only to change into confusion as she saw him

Raynare: and who are you?

heh...time to fuck around a little

(y/n): my name is Masterchief! a soldier from space!

there was a long pause...the silence was almost deafening, but after a couple of seconds both Raynare and Issei managed to voice their confusion

Issei&Raynare: what?

(y/n): are you deaf? i said my name is DoomSlayer and i came from hell!

Issei: no you didnt! you said something different!

(y/n): what do you mean different? how hard is it to understand, my name is Dr.Bright a researcher from a super secret organization that keeps the world safe! see? its easy.

...

...

...

...

...

Issei: W H A T ? ? ?

he could swear that he saw black smoke coming out of Issei head, it was quite funny to mess with people

Raynare: enough! i dont know who you are but i wi-

(y/n): EXPLOSION!

yelled the young crusader and aimed the spell at the fallen angel, a second after he said it a explosion took place where Raynare was floating, the thing he didnt expect was the fact that he would kill her with it...well at least he heard a ding in his head so he managed to level up! thats good right?

bits and pieces of the fallen angel landed on the ground and both (y/n) and Issei were staring at the spot where Raynare was shocked. (y/n) because he didnt expect for his spell to kill Raynare, he thought it would just stun her and give him time to grab issei and run.

Issei on the other hand because he could not believe what just happened, his new GF grew wings and the next thing he knows there is this guy who killed her by making her explode...

...

...

...

...

(y/n): well my job is done! have a nice day and see you around!

said the young crusader as he tried to walk away like nothing happened. but Issei was not having it however, because when he heard the young crusader saying that, he snapped and said

Issei: HEY! wait a second, you owe me an explanation!!

the young crusader hearing him stopped and let out a tired sigh. well Issei will be introduced to the supernatural sooner or later so he may as well know it now right?

(y/n): alright fine!

said (y/n) and faced Issei while clearing his throat

(y/n): the supernatural is real, your GF was send to kill you, and i am a crusader that does what god ask's him to do, oh and also you have this thing called a "sacred gear" and it allows you to multiply you power thats why she was send here to kill you

Issei: as i would believe that!

(y/n): you just saw a fallen angel being blew away by an magic explosion and you still doubt what i said?

after that Issei fell silent...

(y/n): well i need to go, it was nice meeting yo-

Issei: w-wait! what should i do!? if thats the truth, then they will send more people to kill me right?

hearing the question (y/n) let out a hum and said

(y/n): yup! your fucked, good luck!

he then wanted to resume walking away once again but stopped as he heard his System giving him another mission

[second mission: (y/n)-sensei!]

[description: teach issei how to fight, and use his powers so he could become a powerful ally against ???]

[reward: {heavenly dragon DNA}(must be at least lv 10 to have 1% of survival)]

[failure: Issei will be hunted by ??? and eventually killed while Draig soul will be destroyed]

...

...bruh.

(y/n): hey! i have a proposition! if you want i can teach you how to protect yourself!

Issei: h-huh?

(y/n): you are already targeted because of your sacred gear, and to be honest with the one you have, it would be impossible to stay out of the supernatural world, so the only option you have is to train and learn how to survive!

after saying that (y/n) took off his bucket helmet and looked Issei right in the eyes

(y/n): worry not! for i am merciful enough to let you become my student! what do you say!

---time skip brought you by chibi (y/n) explaining to Chibi Issei why thighs are better then boobs---

Issei: I HAVE BEEN ENLIGHTEN! THE HOLY IMAGE OF WOMEN THIGHS HAS BEEN THE CORRECT WAY ALL ALONG! SCREW BOOBS! THIGHS ARE THE WAY OF LIFE!!!

(y/n): glad i was able to enlighten you my student

said the young crusader as he nodded his head sagely, he spend nearly 3 hours trying to make Issei see the error of his ways and correct him on his path

Issei: sensei thank you!

(y/n): you are welcome, my student :)

sudently both (y/n) and Issei heard a voice calling them

Ms.Hyoudou: BOYS, THE FOOD IS READY!

oh, forgot to mention but since (y/n) decided to stay and become Issei teacher, the system informed him that Highschool DxD is now officially the third world that he can visit without paying, the only problem is that this world time will not stop when he is in the fantasy or RWBY world.

and since he was now in charge of teaching Issei and protecting him until he learns how to fight, he decided to stay in the DxD world for some time, and since he didnt have any place to stay Issei offered him to stay for tonight in his home.

at first (y/n) was not sure if it would be okay to come unannounced, but Issei parents were a little too enthusiastic to let him stay...and the reason was because Issei never had a friend who would stay over...

remember that Issei in the show was a part of the "pervert trio"? well this does not exist in this world, either Issei never meet his two friends or they didnt exist at all...well, its a small info, but its an important one because it say's that this is not the original timeline of the show and some things are different, how much different he didnt know, but he kept it in mind

(y/n)&Issei: Coming!

they then both exited Issei room and went downstairs to the kitchen, where food was already prepared.

(y/n): thanks for the food Ms.Hyoudou! oh, and also, Issei.

Issei: hmm?

(y/n): you better eat until your full, because we are starting tomorrow!

Mr.Hyoudou: hmm? what are you two talking about?

(y/n): nothing important Mr. Hyoudou...now, with that out of the way...

the young crusader looked at the food in front of him

(y/n): lets eat!

---time skip brought you by Chibi (y/n) and Chibi Issei petting Chibi koneko---

Issei: dude i have school today!

he said as he was dragged by the young crusader deep into the forest where they will begin his training

(y/n): fuck school! school suck's they barely teach you anything there, its just a place with ignorant adults trying to force their wisdom on you instead of teaching you!

...

Issei: ...you were bullied in school, am i right?

...

(y/n): i think you are asking for a beating...

hearing this Issei paled a little, he quickly raised his hands and started waving them in front of his face while trying to get himself out of this situation

Issei: h-hey! i was just joking! there is no need to get angry, right?

(y/n): you just walked into hell...

and at that moment Issei knew...he fucked up...

before he knew Issei was running for his life as his sensei was throwing spears made of silver light at him, they exploded on impact making earth and dust fly into the air

(y/n): faster! run FASTER!!!

Issei: im really sorry!!!!

while (y/n) was chasing Issei he didnt notice that the prince slime has escaped from the treasure bag and went into the forest where a certain white cat was siting on a tree, the slime was moving quietly and quickly at the same, the cat didnt even notice that something was creeping behind him...

Issei: i can run anymore...

he said wheezing

(y/n): dude, your stamina is so low...you literally been running for 1 minute...

Issei however didnt hear him because he was too busy dying from exhaustion.

(A/N: i feel you bro)

just as (y/n) was about to start throwing light spears at Issei again he heard a cat cry and looked in the direction where the sound came from, what he saw was his slime who had trapped a white cat in his gel body, seeing this (y/n) panicked and run to save the cat from his pet slime

(y/n): what are you doing!?

he screamed and grabbed the cat, while getting it out of this pet slime body

(y/n): thats not how you treat animals! if you are hungry just tell me and dont go hunting for cats!

the prince slime was trying to say that the cat was a spy and was a familiar of someone, but this was very difficult since he didnt have a mouth. at the end he just gave up and made a sound similar to a dog whimper, while melting a little due to depression, caused by making his master angry.

(y/n): lets get you clean ok?

he said as he took out a cloth piece and a bottle of water from his treasure bag and started to clean cat fur gently from all the gel, he noticed how calm the cat was and how it was staring at his face the entire time he was cleaning him

(y/n): your very calm arent you?

the cat let out a "meaw" in response and started to nuzzle his head into (y/n) hand

(y/n): and you like being petted huh?

he said and started petting the cat with one hand while creating a light spear with the other and throw it at Issei who let out a girly scream and started running

(y/n): RUN UNTIL YOU PASS OUT!

Issei: ISNT THIS A LITTLE TOO CRUEL!?

the young crusader didnt respond but created another light spear and threw it at his perverted student

(y/n): i said run!

Issei: KYAAAAAAA!!!!

---meanwhile in the ORC---

Rias: koneko, what are they doing?

Koneko: the pervert is running.

Rias: i see...and what is that other boy doing?

Koneko: he is cleaning my familiar.

...

Rias: what?

---back to (y/n)---

Issei: please stop! im really sorry! i will do anything!!

(y/n): buy me 10 cheeseburgers!

Issei: i will do it! just stop please!

(y/n): DEAL!

and just like that (y/n) stopped throwing Light Spears at Issei, who lost all his power in his legs and landed face first into the ground

Issei: you're too cruel, i will die...

(y/n): dude, dont worry i only plan to break some bones and make you cough some blood.

Issei: NO WAY! i will end up crippled at this point!

(y/n): not if i awaken your Aura.

Issei: h-huh? whats an Aura?

he said sounding confused as hell

(y/n): aura is a away of manifesting your soul outside of your body in a form of energy that will protect you by absorbing attacks, it also heals you and gives you more speed and power.

hearing this Issei face was slowly changing from a scared one to a exited one, he wanted to awaken this Aura thing as soon as possible!

Issei: thats so cool! its almost like a cheat!

(y/n): yeah but it does have its downsides however, for example, it may absorb all the attacks even the lethal ones but it does not negate pain, meaning that you will feel all the pain that the attack would normally inflict.

Issei: oh...but still! its cool! how do i awaken my Aura?

(y/n): close your eyes i will do it for you.

Ozpin explained how awakening someones Aura work when he was giving (y/n) a lesson about Aura, you basically need to reach with your own Aura into the person soul and then bring it outside while reciting a "chant" of sort

(y/n): For it is in passing that we achieve immortality. Through this, we become a paragon of virtue and glory to rise above all. Infinite in distance and unbound by death, I release your soul, and by my shoulder, protect thee.

After the chant was completed Issei was covered in a orange light and a soft pulse of energy was let out of his body, but it was not the end as Issei sacred gear also manifested on his left arm and to (y/n) shock it was already in its final form.

Issei: i feel so light!

he said and started jumping in place to confirm if he truly became lighter, and while he was doing that he noticed the red gauntlet on his left hand.

Issei: woah! what is this?

(y/n): that would be your sacred gear...

why was his sacred gear out? and why is it in the final form? isnt it supposed to be a normal "twice critical" at first? is it because he awakened Issei Aura? sacred gears are bounded to a person soul, and Aura is a person soul being brought to the material world...so by awakening Issei Aura he also awaken his sacred gear? it would make sense...

(y/n): well i guess its good for you, but lets not get distracted! i should explain what a semblance is now that you have your Aura awakened.

Issei: hmm, Semblance?

(y/n): a Semblance is a superpower that everyone who awaken his Aura has, it uses Aura as fuel and is usually a very good thing in a fight.

that being said, what was his semblance? he awakened his Aura some time ago but he still didnt discover it...

Issei: thats soo cool! so whats mine?

(y/n): i have no idea-

Draig: Pyromancy, he is able to control all kind of flames, even the magical ones

...

the hell?! why is Draig awake? shouldnt he be awake when Issei was- you know what? lets stop questioning this! just go with the flow!

Issei: D-DID MY GAUNTLET SPOKE!?

(y/n): ah, yeah, forgot to tell you, but your gauntlet has the soul of a dragon inside it. btw hi Draig how was your nap?

he said in the most casual way he could

Draig: quite refreshing! but who are you human? i dont think i know you.

(y/n): my name is (y/n), im a crusader and i am also the teacher of that Pervert known as your host

Draig: greeting (y/n)! my name is Draig im a heavenly dragon of domination! i will be leaving my host in your care!

(y/n): leave it to me!

he said while raising his hand with a thumb up

Issei: can someone please exp-

Issei didnt have time to finish however as he saw that a light spear flew past his head

(y/n): now that you have your Aura activated, lets start the real training...shall we?

said the young crusader with a sweet voice and a sweet smile that promised Issei a lot of pain. Seeing (y/n) like this, Issei was terrified and started to run while (y/n) started chase him while throwing light spears at him

(y/n): you will not stop until you run a circle around the whole forest you hear me!?

Issei: please have mercy! ;-;

(y/n): mercy is for the weak!!!!!!!!!!
