Mina, Kiana, Mei, Bronya jumped out of the building as an Emperor Class Honkai beast slashed the sword down and destroyed the building that they were resting, Mina hit the wall of the building opposite to them and was knocked out.

The Emperor class removed it's weapon from the rubble and moved to attack Kiana, Mei, and Bronya.

Bronay: Project Bunny: Activate.

Once Bronya summoned Project Bunny 19c both it and the Emperor class' Lance clashed causing a shock-wave throwing the debris away.
Both were in a stalemate, but Suddenly the Emperor Class thrust's its lance causing Bronya amd project Bunny 19c to be knocked through several buildings.

Mei: Bronya!

But before Mei could say any thing the felt a shadow over her head and looked up, seeing the Emperor class bringing it's sword down on her.
But before that could happen Kiana stepped in and pushed Mei out of the Way.

Kiana: If you keep thinking about Bronya...
*close to Mei's face*
Kiana might get really jealous, Mei!

Then the Emperor's sword slashed Kiana's back, causing blood to flow out of Kiana's back.
Both hit the ground, while Kiana's unconscious body was on top of her.

Mei: Ki... Kiana...

Mei Said while her eyes were wide open, she then Proceeded to Hug a Bleeding Kiana, then started crying, while the Emperor class was standing tall above them, and when it brought down it's sword in order to kill them, then everything was covered in smoke when it brought it's sword down on Mei and Kiana, then it is revealed that Mei and Kiana were protected by a barrier of sorts, then Electricity flows out of the barrier Staggering the Emperor class, then Mei's turn a a violet shade and er Iris turn into slits and suddenly patches of her clothing rip more Specifically her shirt's sleeve, and Pelvis region which suddenly tattoos appear on her arm and said body regions.

She then Floats into the air while "wings" of solid Honkai energy form behind her and looks at the Emperor class as if looking upon a worm.

This wasn't the lovable girl with a big sister personality Mei, the look on her eyes was cold and cruel, this was the 3rd Herrrscher, and she was pissed.

The Herrscher used it's power to create an orb of lightning above the Emperor class' head.

H-Mei: The queen does not except your service worm!

Then the Orb of Lighting descended upon the Emperor Class and it started to deform and "bubbles" formed around it's body, suddenly it exploded in a beam of plasma shot up into the sky causing the buildings close by to be turned into rubble while several Honkai beast watched the beam

In the Hyperion

CIC #1: Honkai Energy Spike detected up ahead!

CIC #2: Honkai energy Rising rapidly!

CIC #3: All Honkai Beasts in Nagazora are moving towards the energy spike!

Himeko: Looks like we've hit the jackpot this time

Adjutant: There is still time to retreat Major!

Himeko: Nonsense!
I will not let go of a prey I've set my eyes on.
Level 1 alert! All crew to battlestations! The was Has begun!

Back at Nagazora Incident

While all this was going on Mina was laying beneath some of the rubles caused by Herrscher Mei,
Mina she was standing, beneath some rubble.

H-Mei: What a mess. Getting injured trying to save that Coward Kiana!
You better wake up right now allow you to die like this.
I'm the only one who can take away your life.

She said with a cold and cruel tone .

Then Suddenly wind picks up and she hears the rearing of the engines. The Herrscher Looks up and sees the Hyperion entering the Vicinity.

Himeko*Thought*: So that's the Herrscher?
A girl? Really?
I thought It'd be far scarier, with death rays , octo legs, slimy tentacles, and super long tongues, or something...

Adjutant: Major, you sure have some sick fantasies with this honkai.

Himeko: Yeah, because some idiot messed up my date.

Then Himeko threw her arm wide open and gave an order.

Himeko: FULL BROADSIDE! HIT IT WITH EVERYTHING WE'VE GOT!
Light her up like a Christmas tree!

Then all of the Hyperion's guns are locked and loaded from Vulcan's to Energy cannon, below the Herrscher was looking with an infuriated look.

Mei: insects!
No one is allowed to stand above the queen!

Then a dome of lighting forms around her just like when she did with the Emperor class. Himeko saw the attack coming.

Himeko: QUICK! MAXIMUM POWER TO THE SHIELDS!

Mei: Die.

The beam shoots towards them Hyperion damaging it upper deck.

Elsewhere

Schicksal Far east assembly hall.

CIC #1: Hyperion has entered the Honkai corrupted area

CIC #2: Signal interference has severed our comm link.

CIC #3: We received this footage before the signal cut out.

CIC #4: This girl... She's the Herrscher?

He then sees the Honkai beasts kneeling in front of her in submission.

CIC #4: Are the honkai beasts kneeling and Submitting to her?

CIC #5: Unable to identify the Herrscher's identity. There are way to much interference.

CIC# 2: It's not just the Hyperion. All the satellites above the city are down. The Herrscher may have unleashed an EM pulse.

???: She's finally here...

Then a girl that looked about 12 years old spoke up. She was dressed in a nun outfit with gold trimming, she had white hair and blue eyes, and her facial feature she could pass as Kiana's sister, if it weren't for the fact that she wasn't, her name was Theresa Apocalypse, the overseer's adopted granddaughter.

Theresa:... A new Herrscher has appeared after a 14 year long Hiatus.
It appears the end of the world is coming.

She finished with a grave tone.

Hyperion's system: WARNING! EXTERNAL PLATING COMPROMISED.
POWER GENERATOR DOWN BY 40% RECOMMEND IMMEDIATE WITHDRAWAL.

Adjutant: We can't take another hit like that

Himeko: GRRR! This Little brat has no Idea how Freakin' Expensive is to reapir this boat

She then threw the coat off of her shoulders.

Himeko: Activate Nuclear reactor No.5 an 6, maintain furnace output. Switch to reserve power!
Bring us to herrscher's in 2 minutes!
Gotta deal with that brat face to face.

Himeko then left the command bridge, and went to dress up in her Battlesuit, Her Adjuntant saw where this was going and decided to follow her.

Adjutant: Wait you are not thinking of using that are you?

Himeko: As if we even have the Luxury of more Options.

Adjutant: But you know what were the Council's orders, Capture the Herrscher not kill her...

Himeko: Yeah thanks for the reminder, we could do that if it weren't for the fact we are the ones getting killed here.

Himeko then removes her dress.

Himeko: If I had to take off my clothes, someones definitely going down in flames.
XO* you take the helm.

Adjutant: Aye, Aye Sir.

While every thing was happening Mina who was unconscious was being engulfed in a purple light.

Inside Mina's Soul (BECAUSE MINDSCAPES ARE OVERDONE TO DEATH AND I'M SICK OF 'EM!)

Mina woke up in a white landscape, there was no buildings nothing not a single person, and neither Kiana, Mei, nor Bronya were to be seen.

???: So you are finally here.

Mina Turn's around and see's a reflection of herself, but with both eyes.

Mina: What do you want wench.

H-Mina: What aren't I allowed to make my host feel Comfortable?

Mina: I'm not in the mood for your mind games, Speak now!

H-Mina: My, My, still inpatient aren't we?

Mina: GET TO THE FUCKING POINT NOW!!

H-Mina: Calm down, little human, I need to borrow your body.

Mina: What makes you think I'll let you take over my body?

H-Mina: Do you think that is a question?

Mina: Before Mina could do anything her Herrscher reflection grabbed her by the neck and lifter her into the air.

H-Mina: Take a rest and leave it all to me.

Then Mina's world turn's into black.
