As Himeko followed by Kiana and Fu Hua entered the entrance to the Cavern.

Kiana: Man It's dark in here, are you sure that there won't be any honkai Beasts?
*Thought* I hope Mina's Alright.

Himeko: I don't know, and please shut up before you jinx us again.

Kiana: Fine.

Fu Hua: Major do you think we'll find the Xuanyaun Sword along with Mina?

Himeko: Well we saw that Beast swimming here so it must have brought Mina here.

Fu Hua: Fair Point.

Then they saw a Dim light.

Kiana: Over there.

And so Kiana swam at the Light which was the Entrance to the Cavern.

Himeko: Well done Brat. You have been useful for once.

Kiana: Hey, I take offense to that. 

Himeko: And Nobody Cares.

Once the Group got out of the underwater Cavern and into Dry land they took Off their Diving Gear.

Kiana: This place's bigger then it looked from outsdie.

Himeko: Yeah.

Then Suddenly the Cavern Started to Shake and Rock falling from the Ceiling.

Himeko: Look out!

Himeko Yelled as she Pushed Kiana and Hua out of the Way as a Part of the Ceiling almost crashed and smashed Kiana and Hua into a Thin Red Paste, though not without Breaking the team apart and Himeko falling on her back.

Kiana: Aunty Himeko are you alright?

Himeko got up and shook he head so she may regain her bearings.

Himeko: Yeah I am alright.

Hua: I guess We'll have to find another route Major.

Himeko: Alright See you guys on the Other Side.

Himeko Said as she looked around the Cavern, awaiting for her and the other Two to Reunite.

 Himeko*to herself*: Might as well look for Mina.

She told herself, as Himeko walked around until she Noticed a Sword stabbed onto the Wall of the Cavern and created a Dim light and saw a pair of Stairs and as she walked up Himeko quickly Identified the Sword as the Xuanyuan sword.

Himeko: So that's the Famous Xuanyuan sword of the Yellow Emperor? Perhaps...

Then Himeko grabbed the sword's handle and with a little difficulty she managed to remove the sword from the wall, and was surprised that it was rather light despite it's heavy looking frame while it's gem glowed a bit.

Himeko: Huh it's pretty light.

Then she heard something and looked to her right to see a Mirror, she walked over to it.

*Time Travel teen Himeko*

Teen-Himeko: Is this my high school Uniform?

Then her father came in.

"Dad": Himeko Are you ready? You are going to miss your graduation if you don't leave soon.

And as soon as she heard her Father's voice she turned around to see her father. But instead of her Father, she saw a Honaki beast in her father's place, which charged at her and pined her to the floor with nothing to do other then face death she impaled the Xuanyan sword onto the beast that her father became, and some of it's blood dropped onto Himeko's face.

Then the Scene changes with Himeko strapped onto a chair waiting for the Stigmata implant, but before they could start, Theresa was in front of her, this was the time they First met.

Theresa: Miss Himeko, My Name is Theresa. I'm Sorry about your father... Were were old friends. I never expected him to Transform into a Honkai Beast. You've been Corrupted by Honkai energy. Do you want to wait for the Inevitable, or Endure the Pain of Undergoing Surgery to become a Valkyrie and keep fighting? I can only show you the Door, the Rest is up to you.

Younger Himeko: You needn't have asked of course, I'll keep fighting, giving up doesn't suit me!

Theresa: Good Himeko. But I have a better proposal

The Suddenly a Large Syringe appeared in Theresa hand's, causing her Eyes to widen, as Theresa's appearance a Pair of Elongated ears akin to a Fox and her fangs elongated, while her pupils became slited.

Theresa: Let's pump you full of Honkai energy so you can follow your father's footsteps. And become more then just a beast you'll have infinite power and immortality.

Then as Theresa was about to lunge at Himeko with the Syringe, she Grabbed the Diminutive girl by the collar as she pointed the Xuantuan sword at her.

Theresa: Oh? Raising your sword already? Do you want to kill me to?

Himeko: Theresa, Don't you remember? All Valkyries walk a fine line between Sanity and Corruption. Wall agreed to kill any infected allies hesitation. I'm just keeping my promise.

Himeko said as she strengthened the grip around the Sword's handle.

Theresa: Oh? Then what would you do if it was an innocent little girl?

The Theresa is Changed with Mei.     

Theresa: Raiden Mei...! This girl who knows nothing about the Honkai, is a Herrscher, Mankind's Greatest enemy. Would you kill her?

Himeko hesitated a bit as sweat rolled off of her face, then the Doppelganger flashed a Sadistic smile.

Doppelganger: Hesitating Himeko? You have always used that sharp tongue to cover up your soft, weak, heart, Haven't you?

the Doppelganger pointed and Accusatory finger at Himeko.

Doppelganger: Your hands are soaked with blood, and yet you play the Hero. How long can you keep the Act together.

Then Himeko felt the Honkai Corruption ravaging her body, she lookd at her heands and say that bit of her Flesh were falling and were replaced by bone with hardened-skin and her left eye's Sclera became purple with white parts akin to a Circuitry, while the part below the Right became corrupted.

then she fell on her knees closing her eyes and screaming in pain   

Himeko: AGH!! PLEASE NO!!

???: Even if you weren't human anymore... would you choose to take your own life?

Came the Voice of the Ghostly Apparition the Yellow Emperor who stood above Himeko while casting a look of Petty.  

Yellow Emperor: I'm Sorry... But Fighting the Honkai is no Easy task if you are unable to stand up to you inner demons .

Hiding Behind the Pillars of Stone Sin Mal looked Himeko who failed to Take the Sword off the Stone.

Sin: Huh... Even Valkyries can't do it.

Then the Scene reverts back to a knocked down Himeko.

Sin: What must I do... To Pull that Sword out of the Stone.

The scene Changes to Black as Letter's appear 

Those Who seek to wield the Sword must first pass its test

With Mina.

Mina Suddenly woke up in a Field of White Lilies surrounded by graves with a Large tree and then she Heard someone behind her.

???: Hello there.
