(Y/N) POV

I opened up a gate to summon me to the headmaster's office, but the gate summoned me outside the school. Lilith walked through the gate and she looked equally confused.

Lilith : Um, weren't you suppose to summon us to the headmaster's office, why are we out here?" she asked as I smelled something out of place

(Y/N) : Wait, do you smell that?" I asked confusing Lilith

Lilith : Smell what?" she asked

(Y/N) : I smell smoke" I said surprising Lilith

Lilith : Smoke! But I don't see anything burning" she said looking around

(Y/N) : Exactly" I said as Tyrant spoke

Tyrant : I sense a barrier around the school" he said

(Y/N) : A barrier huh, there's only one person I know who could cover the entire school in barrier" I said

Lilith : Sora" she said as I nod my head

(Y/N) : Tyrant, can we take down the barrier?" I asked

Tyrant : Not by magic, but maybe by brute force" he answered as I pulled Incursio's Key out

(Y/N) : All right then" I said about to plant Incursio's Key into the ground, but Tyrant stopped me

Tyrant : (Y/N) I don't think that's a good idea" he said

Tyrant : After Incursio's evolution, it would not be wise to use it just after getting rid of the dragon energy, there's the chance your body will transform once again, but it might be worst" he warned

(Y/N) : I know that, but if Sora put up this barrier then that means something's wrong, also the headmaster has information about Inson, if I ignore this then we'll have to wait for Esdeath to wake up, which could take a while" I said making Tryant sigh

Tyrant : Very well, but don't push yourself, if you die then I'll lose my favorite host and any chances of finding Inson" he replied as I nod my head

(Y/N) : All right then, INCURSIO!" I roared summoning Incursio's second armor breaking the ground underneath me as Lilith looked at me shocked

Lilith : Wait what!?! It looks different the last time I saw it" she said shocked as I looked at my hand

(Y/N) : A lot can happen in a year Lilith, people change for better or for worse" I said as I stared at the school and began charging towards it

I charged the barrier at full speed and crashed into it with my spear. The impact shook the ground as I began cracking the point of impact. Needing more power I had to use my red dragon evolution.

(Red/White Dragon Evolution is using the powers or equipment from Boosted Gear/Ddraig or Divine Dividing/Albion. Example: Being able to transfer power to others, or half dimension)

(Y/N) : RED DRAGON EVOLUTION : JET" I shouted making a jet appear on my back as I began boosting (Imagine Issei breaking Diodora's Barrier)

Tyrant : Boost!Boost!Boost!Boost!Boost!" he repeated as I began pouring all the power into the jets, putting more force into my thrust.

The entire barrier began cracking, within a few seconds I broke down the barrier, only to reveal the entire school on fire and was being attacked by members of the old devil faction.

(Y/N) : What the hell are they doing here?" I asked myself as two grunts saw me and charged

One tried to pierce me with his spear, but I parry it and cut his head off turning him into dust. The other followed, he used demon magic, but I use Incursio's nullify and negate it. I throw my spear at him and it pierces his stomach and goes through all the way. I hear a couple of gunshots and see Lilith taking out some grunts. After she was done she rushed over to me as I called back Neuntote.

Lilith : Why are they attacking the school, I thought this place was well hidden" she said surprised

(Y/N) : Either they got lucky or we have a mole among us" I suggested as Lilith thought about it

Lilith : But who?" she asked herself

(Y/N) : That's not important right now, we need to drive the devils out of here" I said as Lilith nodded and we rushed at the school taking out any devils who got in our way

3rd POV

Six members of the Trinity Seven were being pushed back in the school field by devils, Yui had to use her Arc Symphony to protect the students inside her dream realm. Mira was using her Gehenna Scope to create barriers and summon giant rock golems to protect her friends. Levi and Akio were heavily wounded and could barely stand up. Arin was running low on magic and began breathing heavily, ignoring her comrades warnings on become a demon if she keeps using magic to her limit. Lieselotte was exhausted from transporting students to safety using her Logos art.

Shalba : Foolish humans, quit wasting my time and accept the inevitable" he said flying above them

Mira : Why are you attacking this school, what do you gain from this" she demanded as Shalba looked at them with a bored expression

Shalba : It's obvious, during the great war humans were able to defend themselves from the three factions by using magic we never heard of, also that you possessed powerful magic users known as Abyss and Astral Trinity who can easily overpower a Satan, when the three factions learned about this they all scrambled the world looking for these humans to further increase their chances in winning the war" he said

Shalba : These humans never found, not until today that is, we finally managed to find you and we plan on destroying you so you could not interfere with our future plans of the new world" he said

Shalba : Weak humans like you should not fight back, we devils are superior to you in every way, give up now and surrender to you greaters" he demanded pointing his hand with a magic circle at the Trinity Seven

(Y/N) : HOW ABOUT YOU FUCK OFF!" he shouted flying towards him using his jet pack and punching Shalba Beelzebub in the face sending him crashing into the ground shocking the humans and devils

Tyrant : DIVIDE!" he shouted reducing Shalba's magic and stamina

Levi : Whoa, who is that?" she asked

Arin : I don't know, but he's powerful" she said staring at (Y/N) in the sky

Lilith : Guys" she shouted getting their attention

Everyone : LILITH!" they shouted excited as she ran up to them

Arin : Did you see (Y/N)?" she asked as Lilith pointed towards the figure in the sky

Lilith : That's him up there" she said shocking everyone as they looked up at (Y/N)

Yui : Big Brother you came back" she said with tears of happiness

Lieselotte : Incredible, he's gotten so much stronger over the year" she said amazed as Shalba stood up from the rubble glaring at (Y/N)

Shalba : How dare you lay a finger on the mighty Shalba Beelzebub, I will make you pay with you life" he shouted angrily as he pointing his palm at (Y/N) who rushed in and grabbed his right arm ripping it right off

(Y/N) : I think you've mistaken me for someone who gives a fuck" he said dropping Shalba's arm on the ground and stepping on it turning it into a slap of meat

(Y/N) quickly appeared behind Shalba and kicked him in the back sending him flying, he followed up by throwing his spear at his body piercing his stomach making him cry out in pain. His body hit the ground with a loud thud, (Y/N) began charging towards him as rouge devils began blocking him. (Y/N) called back Neuntote and rotating the spear in his hand like the blades of a blender rushing towards the devils. Instantly, anyone who stood in his way was turned to mush, the devils cleared a path for (Y/N) to avoid being ripped apart as he rushed to Shalba without anyone in the way. Shalba looked up and saw (Y/N) jumping at him about to impale him with his spear, he pointed his palm once again and fired one last resort attack. (Y/N) saw this and summoned the first devil kings sword in his left hand, Twilight.

(Can you guess where this sword is from?)

Shalba was shocked and furious seeing the long lost devil king's sword in the hands of a human, but his eyes widened when (Y/N) said...

(Y/N) : FULL COUNTER!" he shouted using Twilight to reflect Shalba's magic attack right back at him at double the power

Shalba looked in horror as his attack reflected back at him and caused major damage. He was on the brink of death, he slowly picked himself up with his left arm and glared at (Y/N).

Shalba : DAMN YOU, WHO ARE YOU? I DEMAND TO KNOW" he shouted as (Y/N) flash stepped in front of him holding a white spiraling shuriken surrounding a blue orb

(Y/N) : I AM THE DRAGON OF EVOLUTION! RASENSHURIKEN!" he roared shoving the white shuriken into Shalba's stomach making his cough blood as he was blown away

Shalba was sent flying into the sky as the white shuriken expanded and enveloped his entire body. The shuriken exploded in the air and it left no trace of Shalba, the devils began to panic as (Y/N) picked off each and everyone of them. Some were about to get away, until another barrier formed around the school trapping the devils inside.

Sora : Amazing, I never thought he would get this strong" she said suddenly appearing next to the seven with crossed arms staring at (Y/N) who was currently ripping devils apart

Lilith : Sora, where have you been?" she asked as Sora shrugged

Sora : Places" she answered as Ilia came up behind her

Ilia : Were sorry, Sora wanted to see how powerful (Y/N) was, so she decided we shouldn't interfere" she apologized

Sora : He didn't need the help anyways, come on anyone who is able to stand up help fight the rest of the devils off" she ordered as everyone except Levi and Akio began hunting down devils

~One Hour Later~

The devils have been cleared, Levi and Akio have been healed up while Mira and Lilith search the destroyed school for any missing students. Yui, Arin, and Lieselotte followed (Y/N) who was still wearing Incursio, as he began searching for the headmaster. The headmaster finally showed himself, but he wasn't damaged at all compared to the students which really pissed off (Y/N). So he decided to just get what he came for. The headmaster saw (Y/N) approach and proceeded to reach into his coat and pull out a slightly burned book.

Biblia : Hehehe, sorry the book got kind of ruined during the attack" he said sweatdropping as (Y/N) swiped the book out of his hand and proceeded to read it

(Y/N) began reading and found a page of what Inson really looks like.

(Inson will change his name to Elias) (DO NOT OWN)

(Y/N) : 'Jesus, that's terrifying' he thought looking at Inson's true form

(Y/N) : Tyrant is this him?" he asked

Tyrant : Yes, I can't believe it's really him, I haven't seen that form in centuries" he said as (Y/N) began flipping through the pages inspecting the drawing and checking the type of paper used

(Y/N) : If I had to guess, I'd say this book would have to be over two hundred years old" he said

Tyrant : Any idea on where he is?" he asked as (Y/N) checked the back and cover

(Y/N) : Hmm, it says here he was spotted in Britain in 1801, when the picture was drawn, that's almost 217 years ago" he responded

Tyrant : Address?" he asked as (Y/N) began skimming through the book, but found nothing

(Y/N) : Nope, nothing" he said

Tyrant : This is good enough, when we go on a break, we should head over to Britain and find clues about Inson" he said getting a nod from (Y/N)

(Y/N) : Wait didn't you say he was an elemental spirit?" he asked inspecting Inson

Tyrant : Yeah, why?" he asked

(Y/N) : That is not an elemental spirit" he said looking back at Inson's true form confused

Tyrant : We called him an elemental spirit because we weren't sure what he was, he was good with elemental magic so that gave him the first part of the name, while the spirit part came from his essence or natural presence" he said

(Y/N) : So like a ghost-

Tyrant : DON'T SAY IT LIKE THAT, elemental ghost sounds stupid, elemental spirit still sounds stupid, but it's better than ghost" he stated with a huff

(Y/N) : Alright I get it" he said

(Y/N) was about to leave, but he felt a tap on his shoulder and revealed the Trinity Seven behind him. Immediately, Yui jumped at him...

Yui : BIG BROTHER!" she shouted excited as she wrapped her arms around (Y/N) neck and began pecking his helmet with kisses

(Y/N) : Stop it" he said trying to shove her off

Yui : NO, you need to be punished for leaving me, ONE THOUSAND KISSES" she demanded and began punishment

(Y/N) : Ugh, you haven't changed a bit" he groaned

Arin : You've gotten stronger my husband" she said in a monotone voice

(Y/N) : And your still on about that" he said with a sigh

Levi : Aww, come on, you know you missed us" she said with a wink

(Y/N) : And your still the perverted ninja you've always been" he said as she giggled

Akio : Why are you still wearing Incursio? We wanna see your face, show us that grown man look" she said

(Y/N) : Nope, if I remove my armor, then I won't look the same as I once did" he said confusing everyone

Lilith : What do you mean?" she asked

(Y/N) : I'm sure you all know about the basic principle of alchemy right?" he asked confusing everyone

Lilith : Yeah, of course, In order to obtain or create something, something of equal value must be lost or destroyed" she quoted

(Y/N) : Exactly, well when I asked Tyrant for more power, this is what I got" he said deactivating Incursio revealing his partial dragon face shocking everyone

Akio : Holy crap"

Mira : Whoa"

Lilith : I can't believe it"

Levi : Your a dragon?"

Lieselotte : No way"

Arin : It's kind of cool, I guess"

Yui : You look like a cute dragon"

Sora : You really have changed"

Ilia : My goodness"

Tyrant : And their's only one way to return his face to normal~" he teased as (Y/N) grew a tick mark and threw the sword far away

(Y/N) : SHUT THE FUCK UP!" he shouted as he got a phone call from Kiba

(Y/N) : Hello?" he answered

Kiba : Hey (Y/N), can you come to the ORC tomorrow?" he asked with a worried voice

(Y/N) : Why?" he asked

Kiba : Rias has been acting weird, she spaces out a lot and is always seen lost in thought, I just feel like something's gonna happen tomorrow" he answered

(Y/N) : I don't really feel like it" he replied in a bored tone

Kiba : Please, this could be really important" he begged

(Y/N) : Ugh fine, I'll see if I have the time, message me if something happens, just in case" he said

Kiba : All right then, goodbye" he said hanging up the phone as (Y/N) faced the Trinity Seven

(Y/N) : Well then, see ya" he said waving goodbye, but Yui grabbed his arm

Yui : No, don't leave us again" she said on the verge of tears

(Y/N) : Sorry Yui, but I'm not gonna stay here" he said as everyone looked down sad

Biblia : Maybe they can come with you" he suggested getting everyone's attention

(Y/N) : Explain" he demanded glaring at Biblia

Biblia : Well, it's gonna take some time to discover a new hiding place for the school, and rebuilding it is gonna take longer, so the students can't fall behind in their studies, so I recommend they live with you and go to the same school as you" he said shocking everyone

(Y/N) : I don't want to" he responded with a blank face

Biblia : Don't worry, all has been taken care of, all you need to worry about is explaining the new mansion, goodbye" he waved before disappearing making (Y/N) angry

(Y/N) : He didn't" he said clenching his fist and opening a gate to his house

Once he stepped foot outside his house , the once two story house was now a five story mansion with a massive water fountain outside and a beautiful garden out front, with enough rooms to house Night Raid and the Trinity Seven.

(Y/N) : GOD DAMMIT" he shouted into the sky
