(Continuation)

As the two fought meanwhile with Yorktown we could see her jumping down a volcano.

As the volcano got hit by a huge purple beam.

That made it erupt more as giant fireballs flew everywhere.

Yorktown seeing the two giant behemoth size Bombers immediately aimed her sniper rifle  towards one of it.

Yorktown pulled the trigger as it released 3 bullets blue bullets.

The bullets pierce through the ship one entered in it's engine core.

The second on the ammunition storage and the third was in the cockpit of the ship.

As the bullets then turned in to Bomb that is equal to 75,000 dynamites.

As the bombs detonated making the ships core and ammunition storage explode.

Making it explodes with an explosion equal to that of 10 MOAB.

Yorktown then jump into a hole in the ground and hid in it.

As the other giant Bomber flew past her as she sigh in relief.

Yorktown:*sigh* only one more and I still need to help Enterprise.

Yorktown said as she peak out of the hole and see the giant bomber 2 km away from her.

Yorktown: that should give me enough time.

Yorktown said as she then aimed her sniper rifle towards the giant bomber.

Yorktown sniper rifle began to glow in blue and white light.

As Yorktown absorbs the surrounding matter and convert it into Light Energy.

The Bombers seemed to have noticed the light from Yorktown sniper.

As then turn around and aim it's cannon on Yorktown.

Yorktown saw this she ready to release when she suddenly heard something speak in her head.

And she followed what it said as she spoke.

Yorktown:Umi no shinpan.

Yorktown said as she pulled the trigger and several New York Class Battleship with  numbering over 1 million appeared.

As the Battleship all aimed there cannons towards the Bomber..

As all the ships then fired it's Railguns and Mk12 Wave Motion Gun.

As millions of blue beams all went towards the Bombers along.

Causing a massive shockwave that made the half planet shatter into thousands of pieces.

And nearby planets got split in half or moons shattered.

Meanwhile with Cleveland and the others we could see there jaws has litteraly drop to the floor.

As Hornet mind was blown away off what her sister just did.

Hornet then first snap out of her trance and then she screams.

Hornet:HOW THE HELL DID THOSE TWO DO THAT?

Hornet said as it made the others snap out of there trance.

Cleveland: so cool how come we don't have that.

Cleveland said in awe as her eyes have stars in it.

Denver:I want one like they have.

Columbia: maybe we have those but ours provably be different.

Hornet:but that doesn't still answer on how they do such ability.

Hornet said as she look back at the battle.

Meanwhile back with Yorktown we could see her dumbfounded at what she did.

Yorktown:h-how did I do that?

Yorktown asked herself as she then lands on a huge rock.

As she looks around and see everything is shattered to pieces.

Except the other half of the planet as she could see beams and explosion on the other side.

Yorktown: big brother and Enterprise must be fighting over there.

Yorktown said as she was about to head there when several yellow beams.

Came straight towards her as she was blown a few meters away.

But luckily her Klein Field is still on if not she would get a bruise from the attack.

As a female voice then spoke that caught Yorktown attention.

????:fufufufu your not going anywhere.

Yorktown looked to see who spoke as she saw two Sirens.

As her eyes widen at who she saw as she made all the New York Battlship aimed there cannons toward them.

Yorktown:Purifier and Tester.

Yorktown said as she look to see the two girls have brought over 2 million HS with them.

Purifier: your now going anywhere Yorktown until you beat us.

Tester:hope your ready then shall we Purifier?

But only for Yorktown to use her Halberd to block her punch.

As you could hear a bone cracking and yellow blood dripping on Yorktown Halberd.

Purifier said as she screams in pain.

While this got her distracted Yorktown used this opportunity to kick her in the stomach.

As it sends Purifier straight to a puddle of sulfuric acid that slowly melted her left riggings.

Purifier said as she stands up and gets away from the sulfuric acid.

But the ground suddenly errupted and blowing Purifier away from the two.

And the slice the air as a energy wave wet straight to Tester.

As Tester saw this she immediately dodge it and instead hit a giant rock.

Tester: hahaha you miss.

Tester said while laughing as she didn't notice the rock behind her slowly falling toward her.

Until she hear something coming toward her from behind.

As she turns around see Purifier infront of her.

As the smokes cleared it showed Yorktown completely fine and her Halberd was in its sniper form.

As smoke was coming out of the sniper muzzle.

Yorktown: you are one annoying Advisor Class Siren I wonder how your leader can even tolerate you in the real world.
