My weapons slice through the heads of the spirits that get in my way. Storming through the castle is a breeze. But finding where to even go was harder. Since Ophis' directions aren't helping.

(Y/N): Which way now?

Ophis: Left. Then we'll be there.

(Y/N): I swear if your lying then-

I bash into the door as it gives way. I stopped myself mid sentence and look up to find some weird monument.

Ophis: There it is!

Senketsu:

Ophis: That's nothing to worry about. I don't see Satsuki, so that means we're here first.

Satsuki: Does it really?

My eyes widen as I quickly turn around, weapons ready. Satsuki was sitting right behind me, and...... she's.....not trying to attack me.

(Y/N): .....What? Not gonna try anything? No trick up your sleeve? Plan to backstab me with a body double.

Satsuki: Look, I know I've done bad things to you. But-

(Y/N): But? But!? You made my life literal hell! All the shit you did just because you couldn't take a loss!

Satsuki: And I want to apologize-

(Y/N): Apologize?! Like I'd ever accept it! You've gone too far!

Satsuki: I know...... That's why I want to help.

I start to approach her, gripping my weapons tight. But then I saw her......

(Y/N): .....Koneko.

Satsuki: I saved her from my mistakes. And in the end, I freed her from my control. You can take her back.

(Y/N): So I can get her and leave? No strings attached?

Satsuki: Correct. You could just leave. But......I......I ask for your help.

I..... don't know what to say. Should I even help her?

Kisaragi: [I say help her. Even after all she's done, she wants to make up for it.]

Ophis: [I agree.]

(Y/N): .........Ghhh. Fine. But, after we're done, your not to harm me or the people I care for every again.

Satsuki: Don't worry. This'll be the last time you hear of me.

She stands up and walks twords the pig tower. I stay by Koneko and shake her.

(Y/N): Hey. Koneko. Wake up.

I hear her groan a bit. But she doesn't seem to be waking.

(Y/N): Ophis, is something up with her?

Ophis: Her brain must have been overloaded from Junketsu's strings. I can't give a well enough explanation at the moment due to that spires influence of the area.

(Y/N): We should get her out of here.

Kisaragi: We can't just leave yet. You can't fight while carrying her.

Ophis appeared beside me and put her hand on my arm.

Ophis: I'll stay with her. I can protect her if things to weary.

Senketsu:

Ophis: You'll do fine. Now go help Satsuki. Before she does something stupid to get us all killed. And we should hurry. Who knows what's happening outside.

With I nod, I run to the spire and see the gate is open. I enter it and see her staring at the thing inside.

The spirits coming from the ground gets absorbed into it the moment they appear.

(Y/N): What is that?

Satsuki: The tomb of the ruler of this world.

(Y)N): Then why are we here? You got a plan or something?

Satsuki: Yes. If we can stop the souls from reaching it, then we can stop his revival.

(Y/N): Well then, how do we do it?

She's silent as I wait for her answer. That's when I notice something was off.

(Y/N): Satsuki, where's your sword?

Satsuki: What sword?

(Y/N): Your sword, Bakuzan. The secret blade or whatever it was.

I wait for her answer again before she chuckled.

Satsuki: So you finally noticed. I expected my successor to be much brighter.

Upon hearing her words, I'm suddenly grabbed by some spirits. My weapons are de-summoned. Just being restrained makes my feel weaker. Why are these spirits feel different then the others?

Senketsu:

(Y/N): W-what a-are-......Satsuki?

She turned to face me. That's when realization hit me. Her eyes......were a glowing green.

Satsuki(???): Satsuki is long gone. At least the one you know. She did something so stupid. So....idiotic. And in turn, I took her body as a vessel. To speak with you.

(Y/N): M-me? Who are you?......What......What do you want?

Satsuki(Viego): I am Viego, the Prince of the Shadow Isles. And what I want is simple......Become the new ruler in my place. My body cannot last any longer and this one is only a means to an end......But you. You managed to do what no one else could. You gathered the factions together. Well done. It's clear to me that makes you worthy of my attention.

I struggle against the spirits, trying with all my might to get free. But the more I fight back, the more I feel myself weakening. I can't even hear Senkets or Kisaragi. This is bad......real bad.

Satsuki(Viego): Don't struggle. Draining the energy I need would take longer if you do. Just relax. It'll be over soon.

I'm....getting.....weaker.....I can't.... can't.....

I......

...have too....

.....keep....

𝔽𝕀𝔾ℍ𝕋𝕀ℕ𝔾!!!

I feel myself break free from the spirits holding me down. Something is different....something FEELS different. This....burst of strength. Of power.

Kisaragi: (Y/N)! Are you alright?

(Y/N): Yeah. Even better actually. This is your power right?

Kisaragi: Yes. In a sense.

Senketsu:

I can tell what she means. All of her power seeming was funneled into Senketsu and amplified. More spirits try to get close to me, but my energy immediately burns them away.

Satsuki(Viego): Fascinating. To think your power increased tenfold. Your will to live is stronger then I first thought.

I look up to this body stealer. Like I'd ever let myself die!

(Y/N): Face me. With your real body. I'll finish you. Here and now.

They chuckle as the tomb behind them starts to crack as the chains break.

Satsuki(Viego): Fine. I'll rip and tear your world apart like those traitors did me! Your energy will be the fuel to my fire!

The tomb breaks as the green energy flowed out and into the fakes body. Their form began to shift and change. It almost feels like I'm looking in a mirror. But I'm not. There's no mirror. Only someone wishing to cause problems to the world. I glare at them and summon my weapons again, griping them tight.

(Y/N): Come! Face the full power of 𝕊𝔼ℕ𝕂𝔼𝕋𝕊𝕌 𝕂𝕀𝕊𝔸ℝ𝔸𝔾𝕀!

Viego: No matter what power you have, I'll cover you and this world in darkness! You'll know the true pain I've felt first hand!
