'No One Will Save You From The Ghost'

Currently jogging down near Union Academy street at 4am, was a you boy at the age of 20, he was jogging alone going a 50 mile jog around union after 2 hours jogging he finally made it back his dorm, he got in and took a shower before chagring into shorts and shirt, and he headed to the kitchen began making breakfast.

As he grabbed his breakfast he sat at the table and began eating, as he looked at some files in front of him each one had different mission name one it, but that would have to wait.

===[Time Skip Thought School]===

As Y/n got dressed hegan to making his way to his class, as he spotted his bully: Rias peerage, Sona peerage, _WBY, Nora, SSSN, CFY_, class A-1, class B-1, team Hanzo, team Gessen, team Hebijo, and team crimson.

But there is one person he glare at is Yumi and her beauties.

Yumi is a fairly tall girl with pale skin, light blue eyes, medium dark gray hair and an overall average complexion. She uses to adorn her hair with a wide white ribbon tie with blue stripes on ends.

Yumi is a calm and serious girl, taking her responsibility of leader of the Gessen elites, also recognized as stubborn for sticking to her goals and ideals, and their applications. She can still be naive who impressed him enough.

All suddenly the sound the academy bell is heard he then looks up at the clock and it says 3:30 for Glynda combat class.

He headed back to his room a long hallway the way he got a lot glares and bad talk from other students Y/n just ignored them and soon arrive at his room he opens goes in and then closes the door inside Y/n room he has the normal academy stuff then he then go to his closet and open the closet door and stare right his armor set.

Y/n slowly put each of his armor piece together, the armor take like 20 minute for him to done.

Y/n: "Well, it's time to let the 'Ghost Out...' Better bring 'The Wing Of The Fallen Archangel' rosary with me."

He then grabs rosary and wear it on his neck and leaves his room and goes to the combat class, once he near the door he opens the door and it's greeted by the same thing.

...?: "Mister FL/N, you late always i see... (Looking right at Y/n and saw him wearing his armor)... Since when you wear a armor?... *sigh* never mine about that i give you two hours detention after combat class done."

The woman who said that was the one who teaches combat class

'Glynda Goodwitch'

Y/n just shake his head and doesn't question her, so he just walk alway far from the bully.

Glynda: "Alright let's us begin the class so who wants to fight first match?"

Y/n (Thought): "And, Three-Two-One."

...?: "Right Here!"

The one who spoke raised his hand, he was Union Academy supposedly best studentd who is just a sick f*ck pervert who only cares about girls and woman breast and has one of the most dumb a*s stupidest dreams which is he want to be the Harem King.

'Issei Hyoudou'

Issei: "Me, Yang, Cardin, Bakugo, and Ryuko vs Y/n"

The students smile and agree to the fight. While Yumi, Sona Ruby, Velvet, Pyrrha, Asia, Irina, Charlotte, Cecilia looks at Y/n with an worriedly face.

And for Yumi, she just stare at Y/n armor the color from it and how it well hand made.

Glynda: That is acceptable. Mister FL/N come one to the ring and prepare yourself for the fight."

Y/n doesn't say anything again and just jump over the fence and land the ring battlefield, the bulles do the same.

Y/n see Yang, Ryuko, Issei and the other bullies.

'Cardin Wincheste' 

'Katsuki Bakugo'

'Yang Xiao Long'

'Ryūko Matoi'

The bullies smirked at Y/n but none of them couldn't see what behind Y/n helmet who also smirk and ready for the fight.

Glnyda: "Begin!"

The first one to charge at Y/n was Cardin.

Cardin: "Even you wear that armor loser none of that can't stop from beating you wealking!"

He swing his mace sideway towards Y/n who dodges it by jumping back a liitle and charges at Cardin giving him a nice turning side kick in the neck which send him fly back little.

Ryūko: Take This You F*cking Weakling!"

Ryūko and Yang charge at Y/n from both side, he rolls backward dodging there attacks he then quickly stands up and turns around to block Yang attack.

Yang: "You should give up right now but it's more pleasing to make you scream more weakling!"

Yang punch Y/n in the face but things got even more worse Bakugo just came in and fired at Y/n in point black sending him flying back unitl Y/n use his all 10 finger to stabs into the ground has he drags a lillte, but this time Issei send a punch right at Y/n but he dodge and seen Issei basically never trains so Y/n move to sideway and Issei fist collided with Cardin's face.

Y/n took his chance and go for right arm uppercut right under Issei chin knocking him out for a bit and out of nowhere Yang use her Ember Celica fist punch Y/n right in the armor stomach hard sending him fly far which the pain no effect to Y/n, but it didn't stop there Ryūko comes up and slashed from up left to down right at Y/n back and he falls down to the ground pretty hard making a small crater and breaking his helmet.

Y/n (Thought): "Almost there... just a little bit more..."

The bullies all group up and celebrating on there success, the teacher just smile and the other students 'excpt Yumi, Sona Ruby, Velvet, Pyrrha, Asia, Irina, Charlotte, Cecilia' cheer the bullies then look at Y/n.

Cardin: "Why did the headmaster let someone no power weakling like you in."

Issei: "Yeah, you just a useless nobody shit who wouldn't even get any girl!! HAHAHAHA"

Yang: "Why don't you just die!"

Ryūko: Yeah, with your death the world could be better right now."

Bakugo: "Honestly, you should go to your mom oh wait she got rape by 30 guys right now and even if she not getting rape she just disappointed in a piece of trash shit like you!"

After that everyone in the stand started calling him loser, weakling, pathetic, trask, shit and bad mouthing him and the teacher didn't do nothing they just don't care and they will never care.

Y/n (Thought): "You... Mess... With... The... Wrong... Person... Union..."

Then Y/n closed his eyes and everything start to slow down and then he start to pray.

Y/n: "O Mater, laudes tuas cantabo, Adoro te, quia magnus es et laude mea dignus. et annuntiabo gloriam tuam omnibus audientibus et narrabo mirabilia tua, quia fidelis et verus es ad salvandum et conservandum populum tuum. Tu fecisti coelum et terram, Tu super omnia regnas, Tu maior es omni mundo. Gaudebo de tua virtute et virtute, sciens te plus esse quam problemata quae me spectant, sciens te mecum esse per omnia, sciens te reginam meam et salutem meam."

Y/n started to build up the energy unnoticed to the other around him.

Y/n: "O Mater, te laudabo et praedicabo bonitatem tuam in valle altissima. Imple cor meum Tuis viribus, Tuis viribus, Tu potentia."

Y/n eyes started to change he then place his right hand on the ground which he used to push himself up and he slowly stared getting up and the bullies saw this and just laugh at him.

Issei: "Hey! Stay down there you weakling fuck! No one said you can get up."

He charge at Y/n and goes for the punch but Y/n catches it which shocked Issei and the other around the arena stand.

Y/n: "Te, Mater Caelestis et Omnipotentis, adoro te laeto corde, jubilantes in gaudio propter te, Mater mea. tu me fecisti et ego tuus. Magnus Pastor meus es tu, protector meus. Nihil metuam dum te sequor. deduces me in pascuis virentibus et in aquis adhuc recreabor. Dirige pedes meos per semitas rectas, lateri meo ambulans, licet per vallem umbrae mortis incedo."

Issei: "Let Go Off My Hand You F*ck!!!!!!"

Yang: "Is he praying?"

Y/n: "Non timebo diabolum quia tu mecum es. Proteges me et consolaberis me omnibus diebus vitae meae. Cantabo igitur tibi carmina laudis et actionis gratiarum, quia bonus es, et amor tuus manet in aeternum. Tu fidelis et verus es et me amas charissime."

Y/n shot out a waves of red energy pushing all the bullies flying back and hit the wall, the red energy around him started to grow even more and the all union they could see Y/n slowly open his right eyes and saw some thing that make them scared for the rest of there life mostly the devil and the devil King Sirzech Gremory or the title Lucifer.
