______________________________________________________________________________
(Previously)

Solomon: so we will have to fix this by going to war then.

Solomon said as Y/N nodded at this as they all stand infront of Y/N.

Y/N: yes and let operation Dies Iraes begin.

Y/N said as the Final War of the plane of Gaia has begun.

______________________________________________________________________________
(Continuation)

After the meeting all of them began to prepare all troops to the Orion Class Assault Carrier Ships.

There is more than 21 of the carrier all within the beast a mostly each carry over more than 3.9 million troops.

With Artoria, Gilgamesh, and Jalter army all in one of the the assault carriers.

All are preparing to launch themselves to the Holy Roman Empire.

With over more than 78 Billion troops preparing themselves to be launch towards the Holy Roman Empire.

All are now entering the carriers were they are all lining themselves within the Carriers.

Y/N an the others have came to an agreement where they  will split into 3 groups.

With Y/N he is going to join with Jalter, Scathach, Astolfi, and Da Vinci.

Since Jalter is a cousin to the Empress of the Holy Roman Empire they are going to help.

Y/N will be in control of the Axis Division with over more than 1 Trillion troops on his command

The other group is Walter and Rose will be in charge of the Eagle Division where they will be joining with Artoria, Mordred, Lancelot, and the other knights of the round table.

There mission is to handle the enemy that will arrive in the northern-west border of the Holy Roman Empire.

While Iron Star Division will be in command of Natasha and Alexandria they will be joined with Gilgamesh, Siduri, Enkindu, Semiramis, Tiamat, Fou, Solomon, and Erishkigal.

They are to handle the enemy with the South-west borders of the Holy Roman Empire.

The first batch of troops they have will be the first to repel the enemy attack.

Not to mention the still have a huge number of undead that they needed to take care off.

Possibility of also seeing various undead when arriving at the Holy Roman Empire is a huge possibility as well.

All spies within thf Moragan Empire all have been ordered a retreat since they were all discovered not to long.

Since Rianna has been suspicious as to why her army is decreasing.

And when she found out the whole spies sended on her land have already escape.

While also dealing huge damage to the army with the undead decrease to 500 billion.

As this seem to have angered Rianna as she has now made more undead at her disposal.

With a total number of more than 1 Trillion but still outnumbered by the Celestial army.

Which is 2 Trillion and add with the warships they have they could easily Repel all of them.

Right now though we could see Y/N in a room builted for him.

As he is now wearing is armor the design is that he still wears a trench coat.

With armor plating on his chest that has the symbol of the Celestial Empire.

The trench coat itself is made of Vibranium making Y/N having a huge protection.

Even though his body is already indestructible.

He still wears it anyway since he have grown use to wearing clothing made of Vibranium.

And there are also Vibranium armor plating on his shoulder and knees.

Along with his boots that is made of Vibranium also.

His whole clothing is black and white making him look like an angel of life and death.

Y/N: *sigh* so this is it the final war here in Gaia only 4 days of being here isn't bad atleast I mannage to find one of the last two pieces need.

Y/N said to himself as he then finnish wearing his black and white gloves.

As he turn around and grab his sword that is floating besides a table.

As he grabs and attach it on his left waist.

The sword is looks like a katana except it has some unique design to it.

The handle of the katana is gold and silver colored in design

With the sharp edges having red color on it due to the blade is made of Reverium.

A type of metal that has its appearance first is gold but when melted it turn red.

The metal itself is 100,000 stronger than Vibranium.

Y/N look at the mirror as he fix the medallion on the middle top of his trench coat.

As he finnish fixing it suddenly someone came knocking at the metal door.

Y/N turned around and then spoke.

Y/N: yes who is it?

Y/N asked as he then walk to the metal door and opened it.

The door split open and revealed his son and new daughter Ilya.

Y/N: Gudako, Ilya what are you both doing here shouldn't both of you be back at the castle not here?

Y/N asked with a raise eyebrows as he then gestured the two to come inside.

The two followed him as they both went inside as the two then sat on the couch.

Gudako: are you really going to leave Papa?

Gudako asked with a worried look on his face as Y/N sigh at this.

Y/N: yes I have to go to war son so I will be gone for several hours.

Y/N said as the two of them suddenly jump on him and hug his chest.

Ilya: papa *sob* please don't go we *sob* don't wanna lose you.

Ilya said while crying in tear as Y/N could feel a small bit of tears falling on his trench coat.

Y/N: Ilya I can't I have a duty as a leader to save an allied nation of ours.

Y/N said as Ilya then look up towards Y/N with still crying in tear.

After Zen Ilya grandfather was killed she was heartbroken to know her whole family.

Have made such horrible thing yet Y/N didn't prison them but merely help them.

And when Ilya interacted with Y/N she began to see her as a father of hers one that she never get to experience.

True that she only met her for only several hours but the time she spent with him.

Had truly made her happy and when he mother have fallen for him it was the greatest thing that happened to her but after hearing that he is going to war.

Made her terrified of him not returning as she wants to stop him from leaving her.

Ilya: but what *sob* if you don't *sob* come back?

Ilya asked as more tears came falling of her eyes Y/N seeing this felt guilty about it.

But he has a duty to fulfill as an emperor as he can't just sit on the side.

And watch his army fight against Rianna army of demons and undead.

Y/N: I have gone to many wars Ilya and I have came back alive without getting injured wha makes you thing I won't come back?

Y/N said with a smile on his face as he pats Ilya and Gudako head.

Gudako: but Papa they said that all who go to war couldn't come back after it ends we just don't want to lose you.

Gudako said while hugging him tightly as Ilya did the same bote hug him tightly.

As they try to make sure he wouldn't leave the two of them.

Y/N: look you two I promise that I will come back and there is no need to worry about me I have your mom and uncles to be there by my side and I can assure you both I will come back safe.

Y/N said as the two look back at him with a hopeful look on there faces.

Ilya: you promise?

Ilya said as Y/N nodded at this as Ilya then raise her right hand and made her raise smallest finger while the rest are closed.

Ilya: you pinky promise?

Ilya asked as Y/N chuckled at this as he then used his own finger and hold each other.

Y/N: yes I pinky promise now both of you wipe those sad tears on both of you I want to see both your beautiful smiles?

Y/N asked as Ilya and Gudako wipe the tears off there faces and smile towards Y/N.

Ilya/Gudako: we love you papa don't break are promise.

Ilya and Gudako both said in unison as Y/N chuckle as this as the three of them hug each other.

The three enjoyed the moment for a while.

But it has to end as Walter then came running inside the room.

Breaking the three off there hug as they all look at Walter who was wearing a silver blue armor.

Walter: Y/N we have a problem.

Walter said with a serious look on his face as this made Y/N put the two kids on the couch.

As he then stand up and look towards Walter.

Y/N: what is the problem?

Y/N asked as Walter then explained everything to Y/N.

(Timeskip)

After Walter explained everything to Y/N who was shock at this.

As he called some guards to escort Ilya and Gudako to be taken back to Irisviel.

But without the two giving one last hug before leaving.

As he and Walter the ran to the Infinity Class Dreadnaught ship.

Y/N: what do you mean that Rianna forces have occupied the southern border?

Y/N asked as he ran pass through the corridors of the ship.

With Walter running besides him as the two were running to the command bridge.

Walter: we were all surprise as well at this to are satellites have showed that Rianna have teleported over more than 120 Trillion Undead and 80 Billion demons to occupy the southern land of the Holy Roman Empire.

Walter said as they both then stop infront of a huge metal door guarded by several guards.

Who all immediately bow before opening the door.

Y/N: it seem she is moving ahead as we have expected.

Y/N said as the two of them then entered the command deck that is more than 300 meters wide.

With over two floors on it below is the ground forces command

And the second floor is the fleet command.

Jalter and her knights are all waiting for Y/N and Walter.

As they all then saw the two of them entering the room.

Lily: Y/N you are finally here.

Lily said as Y/N nodded at this as he stand infront of a Holo map.

Walter: Rianna has occupied over half of the Holy Roman Empire all of which are not well heavily defended part.

Said as Y/N and the other look at the map with lands all marked red while the upper part of the Holy Roman Empire.

Is Mark as blue indicating that they still haven't yet been conquered.

Y/N: Jalter have you contacted Nero about this?

Y/N asked as Jalter shook her head at this.

Jalter: I can't me and Da Vinci tried but Rianna has cut off any communication to them.

Jalter said with anger in her eyes as they all know that Jalter deeply loved her cousin.

After all they have grown up with each other until the eo of them had to become Empresses of there nations.

Walter:me and the other Eagle Division should handle the north-east and the Iron Star Division would handle the other army on the north-west.

Walter recommended as Y/N nodded at this.

Y/N: you have my permission tell all the fleets to prepare to warp to the Holy Roman Empire.

Y/N said as the others nodded at this while Walter then teleported himself to the Eagle Division fleet.

Outside all of the ship began to fly out if the base as the whole citizens in Camelot all wish them good luck on the war.

Da Vinci: Y/N all ships are ready to warp to the Holy Roman Empire.

Da Vinci said as Y/N nodded at this as he then walk toward the ships window.

Y/N: tell all of the ship to warp.

Y/N said as the ships all immediately warp creating a large Ultra sonic sound.

As they all then warp to the Holy Roman Empire where the first phase of the operation begins.

To Be Continued.
