Meanwhile back with the others below we could see the huge portal expanding as it slowly growing until to the point it is now reaching the sky.

Hamman: what the heck is going on?!

Hamman said as she look at the huge portal that is now appearing infront of them.

Iowa:I don't know but I feel that whatever that thing is it's bad news.

Iowa said as she feels that something huge is coming out of that giant portal gate that had just appeared now.

Monarch: everyone look.

Monarch said as SR points above the portal and see Akagi floating above the giant portal gate.

Victorious: what is Akagi doing?

Victorious said as she jumps out of her plane as she has finnish taking care of Kaga.

Who is now unconscious somewhere due to being hit by a Taser Missile.

Which is vet painful since she was hit by 6 of it.

Javelin:what is she planning to do?

Javelin said as she stands besides Laffey as they all look a Akagi who has a insane look on her face.

Meanwhile with the Sakura Empire they were now slightly or some of them heavily injured.

Bit most of them were affected by the Taser bombs, shells, or missiles.

Zuikaku and the others arrive at them as they all look at the two crane sisters.

Souryuu: Zuikaku what in the world is going on?

Souryuu ask as she looks at Akagi the portal was getting bigger and bigger than ever an she doesn't like what is going to happen.

Zuikaku:we don't know Akagi-senpai just activated some kind of thing she was holding and the next thing we know she disappeared and that giant portal appeared.

Zuikaku said as she was about to fall on the water when her sister has caught her.

Shoukaku: don't force yourself Zuikaku.

Hiryuu:this is bad half of our forces are heavily injured we won't be able to fight against them.

Hiryuu said with a worried look on her face as she looks at the portal that is getting larger.

Souryuu: what is she planning to do?!

Souryuu said as she see Akagi spreading her hands.

As the said portal gate glowed and what came out shock them.

Fusou:s-siren!

Fusou said as they saw several Humanoid Siren coming out of the portal gates.

However this Siren were completely different this were Super Heavy Battleship Class Siren.

Or more specifically the Rook class a new type of its kind along with the Super Carrier Siren.

Or is called as the Bishop Class Siren and along with the Super Destroyer or called as the Knight Class Siren.

Yamashiro: eep!

Yamashiro hid behind Fusou as she see the Sirens coming out of the portal gates.

Fusou:is Akagi insane how could she work with the Sirens?!

Fusou said in shock as she looks towards the large number of Siren coming out if the portal gates.

Souryuu: now it make sense the Siren production, this world were in and the black mental cube were all came from the sirens Akagi has lied to us.

Souryuu said with a look of disbelief on her eyes as the others eyes widen at this when they all realized they were all fooled from the starts by Akagi.

Zuikaku: why....why would Akagi-senpai ally herself with the Sirens does Kaga know about this to.

Zuikaku said with a look of shock, disbelief, and betrayal in her eyes.

Hiryuu:she's been fooling us around why....why is the reason?

Hiryuu said as she and the others look towards Akagi who looks like is going to laugh insanely.

Meanwhile with the first fleet of Azur Lane there eyes widen when they saw the Sirens.

Iowa:another group Humanoid Siren?

Iowa asked with a surprise look on her face.

Just then Y/N voice was heard through there comm's.

Y/N:Essex can you hear me?

Essex:Big Brother I can here you and where the heck are you?

Y/N:I have no time to explain for now you all should retreat means the second fleet will handle them.

Essex:but we could help.

Essex  retorted bit Y/N didn't agree to risk them getting hurt.

Y/N:this are new type of Humanoid Siren your facing do not engage them without you all getting a retrofit you will be overwhelm.

Y/N said as Essex just nodded at this knowing she won't be able to convince you.

As they all soon started to retreat and Akagi see this as she laughs.

Akagi:hahahahaha, what do we have here Azur Lane running away.

Akagi said as she then ordered the Knight Class HS to attack them.

The KHS all lunge at the first fleet at insane speed not something even a regular ship could do.

Akagi:I'm going to enjoy destroying you all.

Akagi said as she laughs insanely and the KHS increased there speed and head straight towards Essex and the others.

As they were all about to get near the first fleet several beams from the sky intercepted the KHS.

As it made a huge explosion that destroyed the KHS that were going to attack Essex and the others.

Akagi:what the?!

Akagi along with Sakura Empire as they saw the KHS all being destroyed.

Cleveland I don't think so Akagi.

They all look up and there jawdropped when they see Cleveland floating above them with a different riggings on her.

As she was holding a pistol on her left hand and a sword on her right hand.

Cleveland: surrender now Akagi or we will have no choice to use force against you.

Cleveland said as she pointed her sword towards Akagi who merely laugh at this.

Akagi:hahahaha, me surrender oh please you and what army?

Akagi said while laughing as she and 50,000 of the new Sirens all laugh at Cleveland who merely smirk at this.

Cleveland: this army.

Cleveland said as Enterprise and the other appeared behind her with there new riggings with them.

Causing the Sakura Empire to jawdropped when they saw them having different riggings now.

And suddenly the Mirror Sea behind them shattered as a giant ship tht have never seen before came coming out of it.

Akagi was shock seeing them but her eyes almost bulge out of her eyesockets on seeing the giant ship behind them.

With the Sakura Empire they have the same expression as Akagi had but some of them had already fainted in fear upon seeing the giant behemoth.

The ship then glowed as it all then turned to several Wisdom Cube.

And all of them saw Y/N as the Wisdom Cubes all went besides him.

And transform into his new riggings as there was several dragons with large cannons inside of there mouths floating behind him.

Approximately there is over more than 12 dragon heads floating behind him.

With a triple carrier deck floating besides him.

And  forget to mention that there is 2 Mk1 Super Heavy Antimatter Gravity Railguns attach on his waist.

Each if the Railguns have over 10 barrels each and could fire devastating blows on anything it touches.

As he was holding a two pistols that can transform into scythes.

Y/N:well this got interesting but jus surrender now Akagi.

Y/N as he made both of his pistols point towards Akagi who only look at him in anger.

Akagi:I will never kill them all!

Akagi ordered as the siren all obeyed her orders.

They all fired there cannons towards the group above who merely activated there mirror rings.

The mirror ring all absorbed the incoming attacks as this surpised Akagi.

They all split up and lunge at the Siren fleet below them.

With Cleveland and her sisters we could see them all aiming there weapons towards several Bishop Class Sirens.

Cleveland fired her gun and hit several Bishop Sirens with it.

As it pierce the Siren Bishop or BHS for short.

Cleveland jump to the side dodging incoming bombs falling from the Bombers that the BHS launched towards her.

Cleveland: oh no you don't.

Cleveland said as she then fired in the Bombers destroying them immidietly.

As she then used her sword to absorb the attack from a RHS or Rook Class Siren.

The  sword absorbs the energy as Cleveland swing it back to the RHS.

As it then sliced multiple RHS before they all fell to the bottom of the ocean below them.

A KHS was about to lunge at Cleveland when it was hit by a beam in the head.

Cleveland turn around to see her sister Montpelier with her rifle.

Cleveland: thanks Montpelier.

Cleveland said as she then fired several Vacuum Imploder missiles towards a group of RHS.

The missiles hit the group ad began sucking all of them into the sphere and explodes after several seconds.

Then released an invisible force that destroyed the shields tha protects the RHS.

Montpelier: you welcome sis.

Montpelier said as she then kick a KHS in the head.

As her kicks have rip the head of the KHS off of its body.

As then turn around and used the bayonet of her rifle to pierce another KHS but this time she Pierce it's heart.

After that several Bombers were going to hit her when Columbia appeared above slicing the Bombers with her Halberd.

Columbia: wohoo this is fun!!

Columbia screamed as she then lands ontop of a KHS as she crush the head of the said Siren.

As the nearby KHS all aimed there cannons towards Columbia who merely spinned her Halberd.

As it absorb the attack from the KHS and immediately then released it back at them.

As the energy wave cut the head of several KHS tht were surrounding her.

Denver:come over here you wimp.

Denver said as she was fighting against a KHS that is holding an an energy blade.

Denver used the advantage of absorbing the kinetic energy coming from the enrgy blade of the KHS.

As her sword glowed just enough for her to release an energy wave.

She then slice it towards the KHS who merely jmp a few meters away and laugj at her.

But it's expression soon turned from laughter to horror as she see the incoming energy wave.

The KHS didn't have any time to react as she enrgy wave cut the lower part of the KHS.

Causing the KHS to fall apart as the ast thing it saw was another energy blade heading towards Siren.

Before the Sirens vision disappeared and then the Siren head was cut in half as well.

Denver:heck yeah fear the might of the Eagle Union.

Denver said as she then immediately slice incoming bombs falling above her.

Before firing several beams back at the Bombers aove them.

Denver:time to show them are aviation power.

Denver said as this confused Sakura Empire and Akagi but there expression soon turn to disbelief

Denver launched several Cosmo Lancer Bombers as  it flew towards a group of BHS.

The Cosmo Lancers all released Frost Bombs as the bombs hit to the HS.

Before they all turn into ices that soon shattered as Denver fired a beam at them.

Columbia:Denver on your left.

Columbia warned Denver as she accidentally throw her Halberd by instinct towards several RHS.

That was behind Denver as it then spin towards the RHS before slicing the to pieces.

As it then flew back to Columbia as the girls catch it.

Denver was amazed at what her sister just did to the RHS.

Denver:that was awesome Columbia how did you do that?

Columbia:I don't know just throw it by instinct.

Columbia said as a KHS behind her was about to slice her head with a sword.

By suddenly gets hit by a barrage of blue beams that shredded the Siren to pieces.

Cleveland: you two less talking and concentrate we have a battle to finnish.

Cleveland said as she then fired several Liquefier missiles towards a group of BHS.

The missiles hit the Sirens before slowly turning to liquid as they all scream in pain and agony.

Befire they all completely tur to liquid that fell to the bottom of the Mirror Sea.
