Meanwhile, back in the training hub, swings and thuds of attacking and blocking by the father and daughter Kaslana's grunts are echoing in the facility. Kiana tries to land a straight jab at him but he redirects it to his right with the back of his palm.

AI Siegfried: That's it. You'll need to beat me first to get out of this trial.

Kiana: That goes without saying, you dirty old man.

Theresa is observing from the observation room and is thinking about their fight.

Theresa: The fight may look intense, but they seem to be holding back. Is it really because Kiana wants to see her father so badly?

But suddenly her mind went into something radiant and white as an arm of somebody's soul embraced her from behind and whispered.

???: I suppose you're right. My sad little Siegfried misses our baby girl.

She gasped as this voice made her gasp and looked behind her immediately only to see nothing. But then a red alert made it through to her systems and she snapped back to the monitors.

Theresa: What?!

She noticed that the failsafe on Mei had been activated and was tracking her recent movements and motives. She then called out to Kiana about what was happening.

Theresa: Stop the training, Kiana! Someone got into St. Freya and kidnapped Mei!

Kiana: What? Mei?!

She finds out about it and tries to appeal to his father. He notices this and tries to make amends with her and Kiana.

Kiana: Dad! I really gotta go save my friend!

AI Siegfried: But we aren't done with our training yes, Theresa!

Kiana: Just end the training! I gotta go save Mei! She's in danger!

AI Siegfried: Is Mei your boyfriend? Wait, that's a girl's name! You gotta be kidding me, did you go lesbian?

Kiana suddenly blushes and gets mad at him for not admitting it.

Kiana: Going lesbian has nothing to do with this! I have to go and save my friend! Get out of the way already if you're not helping, you dirty, pervy, old man!

He sweatdropped from this and chuckled.

AI Siegfried: Good. We Kaslanas will do whatever it takes to save the ones we love. However...

His smile turns into something menacing and threatening to his daughter. He pulled out his twin pistols that only high-rank Valkyries such as Theresa would know of. Siegfried's weapon is named the Judgement of Shamash.

What they didn't know is that VEDA had hacked into every faction's systems as Y/n arrived, so that's why VEDA and Celestial Being knew everything of this world. Its control of AI Siegfried is thinking of making his attitude dedicated to eradicating the Honkai, just like all the members of this House clan, and wielding the Kaslana's signature divine weapon.

AI Siegfried: I know your friend Raiden Mei is the 3rd Herrscher. I'm sorry baby doll, Herrschers must be destroyed for our species to live. Do not forget the Kaslana oath. We must protect this world from the Honkai's menace.

Kiana suddenly froze on her spot when she saw the barrel of his gun pointing towards her and the barrel was extended.

Kiana: Dad... Why?

He pulled the trigger and fired a massive shot near her face, missing it on purpose and it created a massive explosion behind her. She was sweating in fear and Theresa was shocked at what he was doing.

Theresa: Siegfried! Are you crazy? You just fired Judgement of Shamash at maximum power! That's Kiana! Your daughter!

Siegfried: I'm sorry. I have no choice. I must atone for the mistakes I've made 4 years ago.

Then Kiana's eyes suddenly flickered and overshadowed by her younger self in her memories. Her younger self is kneeling on the snow with blood splatters around. She was wrapped around in a brown robe and her left leg had bandages wrapped around it.

Kiana: I'm seeing my memories...

But she saw her eyes have a slight difference; the left eye still retains the blue eyes however her right possesses a burning gold color with veins of Honkai emitting from its eye.

Kiana: Is this from 4 years ago? What's going on? What happened to me?

Somewhere, Cocolia and Einstein are standing on a giant door with system circuits flowing through it, and three emblems of the house clans are carved on it. House Apocalypse on the center-top, House Schariac on the bottom-left and House Kaslana on the bottom-right

Einstein: Our Sovereign is now doing its work for us. Theresa has found out about our Sovereign's intruding.

Cocolia: Good. Theresa seems to have fallen for our trap, our bait won't last. But no matter, we're just footsteps away from the secret that Otto has been hiding.

As Einstein pulls up her hologram device, she taps a button, and the server vault has been opened, allowing them to enter the vault without any intruders at their plans at all. However, the issues is about to come to clap on their heads soon enough.

2006 (8 Years ago)

I don't remember anything that happened before I turned 9.

Inside a wooden cabin, a young Kiana with winter clothing and a bandage around her left eye sits on a chair, looking at the fireplace.

My old man, Siegfried, told me that my head was injured in a crazy accident. That's why I couldn't remember anything at all... not even my name.

I told him I couldn't remember my name. He gave me these words after a long silence.

Siegfried is kneeling to her level as she looks at his father. A stoic but a hint of depression and despair marks on his face.

Siegfried: Your name is... I don't think it matters. You are my daughter and that's all you need to know.

He told me that my last name was Kaslana and that my mom died before I turned two. He took me away from the rest of the family to live in a lone forest cabin.

Dad was nice to me. He gave me anything that I wanted.

Piles of wrapped gifts are stacked behind Kiana as she reads the book she got from her first gift.

But I wasn't happy. He neither smiled at me nor celebrated my birthday. He would get drunk on my special day. He would mutter two names while passed out.

Siegfried: Cecilia... Kiana...

Yeah, I guess he's not doing an excellent job as a father. But I know that he's also the defender of humanity.

She wrapped a blanket around the passed-out Siegfried and slept on his lap for the rest of the gloomy special night. But then the next day, he just disappeared and Kiana is now sleeping on the floor, not knowing Siegfried is gone.

I remember he said to me that he once worked for a really powerful organization known as Schicksal. But then, he left for retirement and became a lone wolf. A lone wolf that still did anything he could to fight the Honkai.

Dad always came back from his battles bearing terrible wounds and I always worried about it.

Kid Kiana: Dad, why would you keep on fighting when you're so badly wounded already?

Siegfried didn't say anything until he just scoffed and smiled at her. He started talking about his bloodline.

Siegfried: I'm a Kaslana. My blood rises whenever I see people attacked by the Honkai.

It's the first time Dad ever smiled at me. Those words hit me deeply. I want to become a fearless soldier fighting to defend the people. I wanted to become a true Kaslana.

A gunshot was heard and Kiana was aiming the M1911 pistol he gave to her to teach her his combat style.

Dad then taught me the Gun-kata techniques of House Kaslana but...

Siegfried is about to leave to go to another battle outside and Kiana wants to go with him, but he advises her sternly.

Siegfried: Stay home, girl I will not let you take part in the fight.

He always advised me to stay in the House as I was not ready to face the Honkai. His face was so angry and serious that I got scared if I talked back to him.

This lasted until one winter, 2 years later...

2008

Siegfried enters the cabin, exhausted and slowly drifting into unconsciousness.

Kid Kiana: Dad!

After another battle, Dad was heavily wounded when he returned home. I patched him up and got him into bed to recover from his injuries.

But suddenly his phone vibrated on the table beside her, detecting Honkai's presence. She looked troubled and worried as she looked at another table nearby with his Judgement of Shamash pistols and a letter paper.

"I won't let them hurt my daddy, again!" That was what I told myself when I took the gun.

In the snowy mountains where she and her father lived. She was facing an Honkai Beast Templar head-on with her father's twin pistols at hand. 

They both looked at each other waiting for their first move. But they decided to both attack and a battle was started with a flash.

But things didn't go my way. The Honkai beast was too powerful for me. It was about to deal the final blow when all of a sudden...

The Templar is now about to stab her with its sword lance and Kiana closed her eyes. But it didn't come as only she heard was a force that stopped it and cracked the weapon.

A hand is now gripping the tip of the lance harder until it shatters completely. It was Siegfried who came back from unconsciousness and glared at the Templar.

Siegfried: What are you trying to do to my baby doll?!

Siegfried then single-handedly punches through the Templar's head and the energy oozing around his arm suddenly evaporates and the Templar dies.

I thought Dad would be mad at me after defeating that Honkai beast.

Kid Kiana: *sobbing* I'm sorry... I just wanted to protect you. I don't want to see you hurt again...

When he looks at his daughter he can see the resemblance to his late wife Cecilia as he teared up and smiled sadly. He embraces his daughter and forgives her.

Siegfried: My sweet baby girl, I'm so sorry. I'm very proud of you, Kiana Kaslana.

She was surprised that she heard him forgiving her for the first time, not knowing why.

That was the day when Dad gave me my best birthday gift, my name. After that, Dad and I made an oath. We swore to do our best to fight for all that is beautiful in this world. These words echo the true spirit of House Kaslana.

But... I thought things would get better from there.

A small Honkai energy suddenly comes out of the dead Templar and crawls all its way through Kiana's legs. It sneakily got inside her body and a small glow of gold veins flowed around it.

2009

Dad became a different person after giving me my name. He made the worst food ever, but I knew he was doing his best. He also tried to teach me how to drink and flirt. Not drinking his alcohol of course.

He did everything he could think of. Though he sucked at being a dad, I got to fight along his side as his little girl. He was good at fighting. I wanted to be like him and fight for the people I love.

But then, one year passed, and one day, he just... disappeared.

2010

A burning forest surrounds her and the cabin is destroyed. Her right eye has become gold and the bandage is gone.

Kiana: 'What is this place? How did I get here?'

There, she saw her dad in a horrible and traumatic situation. He walks slowly with a big wound on his left side. His left arm is amputated which leaves a massive blood splatter on his left sleeve and the left side of his face.

Kiana: 'Dad! He's wounded! Where's his arm?!'

The Sword no longer functions as it's energy died out and the blade is broken, leaving only the handle. He then walks up to her, kneels to her, pats her head, and embraces her before whispering his final advice before he disappears.

Siegfried: It's arlgith, baby doll. We Kaslanas will do whatever we can to protect those we love. I've done my part, little Kiana. It's time for you to do yours, baby doll.

Reality (2014)

She was shivering as she returned to reality from witnessing her memories, afraid of what transpired.

Kiana: No... No... No...

All of the negative thoughts are emerging from her head, some are saying to remember the memory, and others are denying what happened in her nightmarish past.

Kiana: What just happened...? I think I remembered something, only to forget it again...

But then she heard a click in front of her and saw the AI Siegfried aiming the gun at her head, threatening her to give up on Mei.

AI Siegfried: Made up you mind yet, Kiana? Give up on your friend, Mei! She is a Herrscher! Even if you save her, you'll have to kill her to live up to our bloodline's oath!

Kiana: Kill Mei!? No way! I'll never do that!

The AI seems to notice her stubbornness and has decided to take it too far.

AI Siegfried: Then, if you won't listen, then I'll have to kill you right here!

He suddenly tosses the pistols in the air as two red crystals come out and it slowly merges alongside its guns, forming the burning blade of the Judgement of Shamash's sword form.

From the observatory, Theresa was shocked to see the sword, she now started to get worried badly about Kiana.

Theresa: How could that be? He just unlocked the seal of the Judgement of Shamash! Stop this madness, Siegfried! That's too far!

The Judgement of Shamash's unlocked seal is called Zweihander form. He grabs the hilt as the sword leaks out its blazing flames and the insignia of a crystallized Solium behind his back as Kiana can only see it in shock.

Theresa: 'He unsealed the Judgment of Shamash... Wait, this training system is based on memories! Kiana has seen this blade before, which means Siegfried tried to'

AI Siegfried: Stop being stupid. You'll have to kill the Herrscher eventually. F you won't listen, then I'll have to cut you down myself.

Kiana starts to clench her head in pain as she can see blurry fragments of her memories.

Kiana: Kyaa! No! Don't make me do this!

She keeps feeling the pain of those memories coming back but then the advice that her father once told her was remembered in her head. The mirage figure of her father appeared inside her mind.

Siegfried: Giving up already, baby doll? I thought you were tougher than this. Still remember that promise we made, Kiana? We're supposed to do whatever we can to protect those we love.

Then her eyes shift from traumatic to determined and steady.

Kiana: 'That's right! I don't care if she's a Herrscher or not! I've promised the old man that I'll do whatever it takes to protect the people we love!'

Kiana then grabbed her pistol and shouted at the AI as she aimed it at him.

Kiana: The real old man won't get in my way when my friend's in danger! Eat lead, you fake!!

She pulled the trigger and fired, but it wasn't aimed at his face but instead at the crystal behind him. It shattered after the bullet went through it. He was shocked when he saw what she did.

But then she just smiled and dropped the sword on the floor. He began to change his attitude and congratulated Kiana.

AI Siegfried: You've finally passed the test, baby doll.

Theresa: 'Wait, so he never intended to kill his daughter! Phew, what a relief!'

AI: It seems you've learned a lot after 4 years. My baby doll can take care of herself now. Listen to your heart and have faith in your choices, Kiana. We're Kaslanas. We're the stubborn fools who would give up everything to save the people we love.

He embraces her and Kiana doesn't have any reaction to that and he continues, somberly.

AI Siegfried: I hate to say this, baby doll. It's time for me to go. *cups her face* You shall live up to the Kaslana oath and keep up the good fight, Kiana Kaslana!

He then looks at the filtered mirror and says hi to Theresa watching over them for quite a long time.

AI Siegfried: Ah, Theresa! I didn't notice you up there! Aren't you excited to see me again?

Theresa: Excited?! You gotta be kidding me! I still haven't taken revenge on you for taking away my BFF Cecilia!

AI Siegfried: *smirks* You haven't changed at all. Guess that means I can safely leave my darling baby doll in your hands. She's a bit slow and she needs a little more push, but all in all, she'll be a great Valkyrie.

He looks above the ceiling and smiles as he remembers the past.

AI Siegfried: This place looks underground. Shoddy design. There should be a window for the moon view, next time. I've met everyone I loved under the beautiful moon: Theresa, Cecilia, and my baby Kiana.

Then, his avatar starts to fade away like polygons as he says his final goodbyes to the two.

AI Siegfried: This place would be so much nicer with some moonlight. But seeing you is enough for me, Kiana. You are named after it, the princess of the moon, my only darling girl. Take care, baby doll...

He finally vanishes into polygons, leaving Kiana alone in the room and Theresa at the observatory.

(Timeskip brought to you by the host of Penacony's Inferno's Kitchen: Gordon Rexy.)

Theresa just came down a few minutes later to meet up with Kiana.

Theresa: What just happened, Kiana? Are you alright?

Kiana: I... I don't know, he was so close, but I couldn't remember anything... I just can't remember anything that had happened before...

Tears are dripping down on the palm of her hand and flowing down her cheeks. But she wipes it off and looks at Theresa who has remembered the intruder in their school.

Theresa: We'll fix that problem afterward. We have to go and rescue Mei, now! Follow me to the arsenal. I'll get the Judah and teach those vile scums a lesson!

But suddenly a voice call from Otto appeared on the device on her brace and was startled and troubled according to her expression.

Meanwhile in the dorms, under the moonlight, the battle is still ensuing as the bandage on Mei's left arm has fallen off after a long battle.

Mei (HoT): I'm not amused. I expected this fight to be a lot more... challenging.

(A/n: *holds Might of An Utu* Don't even think about naughty ideas...)

She's just bored and not impressed from the battle she had against the fake Herrscher as her feet is scrubbing on his bruised, scowling face as she faces him with a grin on her face.

Meanwhile, Y/n is running in the forest with the cane of Star Eden on his hands leaving behind the trails of dead Honkai Beast and jammed cameras on its path.

On the other side, Welt has spawned inside the SU and in his costume of when he met the faker, ready to roleplay his past role as the real Sovereign.
