(The Giant is rising. Face the might of the Nazi Zombies in their heartland. This is where it all began. This is where the master plan took shape. Is this where it all ends?)

(Der Riese? Remember the Pack a Punch? Remember that?)
(This is with Ballistic CPU from bo2, and Bo3)
(Union's weapon range/Y/n's classroom)

Y/n:*mind*breath Y/n, find the head and shoot it.

He looks in the scoop and looks at the deathstalker. He pulls the trigger and shot hit heading straight towards the grimm scorpion killing it.

Y/n: One shot, One Kill.

He gets, leaves the gun training area and sees a blue hair neko girl shooting a sniper at a beowolf.
(She's 18 along with the other characters some are older than each other)

Y/n: nice sniper.

????: thanks professor Y/n, names Sinon teammate of Team SAO.

Y/n: Team SAO, oh yes I gave your team some assignments do you have them?

Sinon: yes here they are.

She handed him the assignments, thanks her and gave her permission to use the mystery box and the pack a punch.

Sinon: that's the Locus one of the rarest sniper I've seen in the media and the mystery box gave me that?!

Y/n: yes since the box randomly gives you a weapon from each era like ww1/2, Cold Era, Ww3, future weapons you name it.

Sinon: thank you professor Y/n!!

Y/n: call me Y/n.

Sinon: okay-OOF!!

She trips and Y/n sees her butt making him blush very red like an apple or a strawberry.

Y/n:*blush* l..let me help you.

He picks her up and gave her snipers back, they both blushed.

Sinon:*blush*

Y/n:*blush* p...please leave...

Sinon: s...sorry!!

She left quickly and Y/n sighs but heard his door open as Izumi walks in the classroom.

Izumi: hey umm professor Y/n I want to ask you something.

Y/n: yes?

Izumi: what was that form?

Y/n: what form?

Izumi: the form that you used on Cardin when he pissed you off.

Y/n: Dreadnaught form.

Izumi: that form it was filled with pure defense but it lost it's speed greatly.

Y/n: yes but I was able to use more of my lightning energy to increase my speed more to about more than 435 miles per hour but if I use more then it would a speedy armor.

Izumi: how did you got that form?

Y/n: training my RoyalGaurd style able to block/counter any attacks with great timing instantly kills any enemies in one punch.

Izumi: wow that's so cool!!

Y/n: thanks how Ddraig?

Izumi: he's doing good I training my limit breaker to have more durability, strength and speed.

Y/n:*chuckles* some day we might fight each other.

Izumi: yeah well it was nice talking to you professor Y/n!!

She leaves Y/n's classroom and his scroll rings so he picks it up.

Y/n: hello?

Jamie: hello Y/n nice to you.

Y/n: Jamie how's Kiana, Winter and Kirara doing?

Jamie: doing good they still miss you though.

Y/n: I understand that I'll meet them again.

Jamie: well you're in luck since I have a mission for the three of you.

Y/n: really?

Jamie: yes the white fang have located three swords two of them belongs to a general dog demon while the last one belongs to a sun goddess.

Y/n: thanks for the information when will the bullhead arrive?

Jamie: 20 mins so be ready.

Y/n:*chuckles* I'm always ready

He hangs up and remembers what the voice told me before he passed out.

Y/n: that voice told me to find and get those swords before anybody else. Shit I have to make sure that Cinder doesn't get her power-hungry hands on those blades!!
(20 mins later)

He sees the Bullhead landing, sees the door opening to reveal Winter and Kiana smiling to see their boyfriend again.

Winter: it's great to see you again Y/n!!

Kiana: so how was Union?

Y/n: great well I have to make a student fight me since he's a racist cunt along with his team.

Kiana: I see well he deserves it.

Winter: hope you do that to my "father".

Y/n: yeah since he broken many laws.

He got in the bullhead and flies away to Forever Fall.
(Mini-Timeskip)

They arrived the location, Y/n uses his new demonic powers to sense the three blades which it was north-west. Y/n summons an iconic weapon from zombies... Mustang and Sally with PHD Flopper.

Y/n: now I have the higher ground.

They continued walking and saw a two groups of white fang grunts and to their shock Adam is with them.

Adam: find those blades!!

Y/n:*telepathy* shit they gotten here before us!!

Winter: well we have to stop them!!

Kiana: what should we do Y/n?

Y/n: Kill them....

Winter and Kiana:*gulps*

They taken out their weapons and Y/n shot the explosive rounds causing limbs flying to the air while Adam dodges the round. Y/n takes out his scissor blades and blocks Adam's attack. The bull faunus kicks Y/n knocking him away and Y/n summons Ebony and Ivory rapidly shot the bullets at Adam but deflects them. Then Adam was too fast stabs Y/n's chest causing blood to come out of his chest.

Y/n:!!!

Adam: too weak human.

Winter: Y/n!!

Time stopped and Y/n sees a person walking towards him.

Y/n: who are you?

Zangetsu: do you want power? To protect the ones you hold dearly to your heart?

Y/n: I....I want power to protect.....

????: then you'll face the enemy....

Then they were gone.
(Y/n's Inner world)

Zangetsu: awaken Y/n.

Y/n: oh is this place again. Is this coming back becoming trending? this my own personal hell?

Zangetsu: you see this sword?

Y/n: yeah?

Zangetsu: want this sword?

Y/n: no I don't want-yeah!!

Zangetsu:*throws sword* come on out white!!

????: hahahahaha yes!! I need this!!

Y/n: what the?!

????: good to see you Y/n, I missed you!!

Y/n: stop....stariiiiing...

????: never!!

The inverted Y/n clashes Y/n with the large knife clashing towards the scissor blades.

Y/n: shit!!

He pushes Y/n away and he looks at his inverted self to see his energy.

H.Y/n:*smirks*

Y/n:*mind* with that spiritual pressure and the sword he's unstoppable!!

H.Y/n: come on partner!!! You think that you can defeat your enemies but you gone to soft!!! My name will be changed!!! I'm Manget-

Zangetsu: 500 Episodes to early!!!

Y/n:*mind* he's right I've gotten to soft since I became a teacher but I'll be tougher.

H.Y/n jumps to the air and was about to clash with the scissor blades but the swords were gone switching out the large blade to a weak sword.

H.Y/n: huh?!

Y/n: you're giving it to me?

Zangetsu:.....

Y/n: thank you old man Zangetsu.
(Back to the Real world)

Adam was about slice Kiana's arm but felt Y/n's energy rising up.

Adam: what!?

Y/n: looks like your weapon rental fees are increased Adam.

Adam: I can't even kill a human right!!
(Back to Y/n's inner world)

H.Y/n: he's gone huh?

Zangetsu: he must be strong to protect everyone he cares for.

Hichigo: yes he's the king of this world.

H.Y/n: sure....well I'm done here, hey can I go back now?

Zangetsu: okay.

[There should be a GIF or video here. Update the app now to see it.]

Then H.Y/n starts to disintegrate as parts of him goes back to Zangetsu.

H.Y/n: He's strong...Zangetsu.....Hichigo...

Zangetsu:.....

H.Y/n: Nurture him well.

Zangetsu:.....

H.Y/n: that power is going to....be mine eventually.

Hichigo:*grins*

Then he was gone and Zangetsu looks up at the sky speaking to himself.

Zangetsu: Y/n, "I hate rain. It rains in here, too. When you are moody, it becomes cloudy. When you are sad, the rain comes down... I can't stand it. Can you understand? How horrible it is to get rained on when you are all alone in an empty world? In order to prevent that from happening... I'll lend you whatever power you need. If you can trust me... I won't let one drop of rain fall from that sky! Trust me... you are not alone in battle... Y/n."
(Back to the real world again)

Y/n: you'll regret killing those innocent people you monster!! GETSUGA TENSHOU!!!

Adam: OH SHI-!!

The wave hits him causing huge amount of damage to Adam and his aura. He retreats back the white fang bullhead and leaves. Y/n heals both Kiana and Winter up and they continued with the mission of finding the three swords.

Y/n: they're over there!!

The cut some bushes and saw the three swords but there was a 4th sword.

Y/n: that's odd.

Winter: yes the mission said there were three blades.

Kiana: we can't leave it, the white fang will take it!!

Y/n: I'll take it with me.

he grabs the swords he felt extreme pain, both Winter and Kiana went to him but there was a force field blocking them from helping Y/n.

Kiana: don't worry I got you!!

She charges her punch which summons a giant orange hand and she punches it but it sends her back to a bolder.

Winter: dam even with force it won't help us!!

Y/n: come on!! Pull them!!

He pulls them all with his psychic powers, the pain is now gone along with the force field but Y/n was really tired.

Y/n: man that took a lot of my energy!!

Kiana: mission complete!!

Winter: I'll contact Jamie and contact Twoearle.

Y/n:*blush*

They giggle as they walk back to the bulkhead and fly back to Union as the blades glows reacting to Y/n's energy.
