5 minutes

Laplace: ...Replicant, mate with that human. Get a good taste of how the previous generations bred.

Replicant: Understood.

The replicant then jumped at Marco, who unsheathed his sword, used the Chakra Gate and thrusted it on her chest, right between her boobs, and then he threw the sword on a wall, impaling the thing.

Replicant: Guh!

Marco: You are inferior to humans, do you understand that or notn

Then he raised his free hand and used Gnome's powers, before making the thing's head explode from the impact of his palm. the thing glowed and was sealed into a tiny strange creature.

Marco: Take your ass here, Laplace.

Laplace: ...That was my intention all along. I'll face you myself...

Then the floor opened, and a strange pedestal-like device appeared. A girl emerged from the center of it. At the same time, pipes and cords coming from the walls are going into her body… Strage semen processing equipment extended from extra arms coming from her body, lining the walls.

Laplace: This is the first time an outsider has seen my body… I am the manager of this Drain Lab, Laplace. I am the first ever cyborg created completely from scratch. I am a complete machine.

Marco: *Sigh* Promestein managed to create a cyborg like this… And didn't put a password on her super computer…

Laplace: My brain and my OS is linked with this laboratory. Everything here is under my control.

Marco: I know how this shit works, I already got to school…

Marco used Kurama Gate and stood on guard, before one of the mechanical arms reached Marco, but he cut it off before it could do anything strange.

Marco: Alice, freeze it!

Alice: Yes! I ask the- Kyaaa!

Some metallic tentacles reached for her, interrupting her chant, then Laplace turned towards Marco and said.

Laplace: I know how you two wor-

*Slash*

Marco used Heavenly Demon Revival and threw a wide slash at her chest while she was distracted with Alice, he never had intentions of waiting for her to freeze the machines, and he finished everything in a strike. He knew that this machine's intelligence is smaller than the computers he knows about.

Laplace: It can't be… In the end, it was as Promestein said… Beaten so easily...

Even though her body was split in half, she was still talking and working, meanwhile the tentacles that bound Alice loosened, permitting her to escape.

Marco: Alright, the job is almost done… Now-

Laplace: Sinner Marco, answer my question now… If I was human… Could I live with other humans?

Marco stopped his blade and looked at her with a strange expression.

Marco: ...I didn't expected those as the last words… Well… I don't think you need to be human to live with others, you just need to want it, even if there are humans that will never accept you, some others will…

Laplace: And how can I be accepted from everyone?

Marco: You can't. No matter how a saint you are, there are people who don't like you, take Illias as an example, before this disaster, she was loved from many cities and towns, but the people of Yamatai Village don't know her, and I myself never prayed for her because I never liked her, my family, too, except for my father…

Laplace: ...This short battle was worth it, just to hear those words… Marco, escape from this facility right now. This Drain Lab will be destroyed in 5 minutes.

Marco: ...Is everyone else out?

Laplace: Yes.

Marco: And about the information?

Laplace: Sorry, that will stay with me…

Marco: *Sigh* Alice, let's go…

Alice: ...Yes.

Marco and Alice rushed out, while Laplace saw them leaving.

[Flashback]

Promestein just finished to create a program for Laplace on her old laboratory and said.

Promestein: One of your primary objectives is to protect confidential information. If control of the Drain Lab is ever uncertain, detonate the facility immediately.

Laplace: Understood. If control is ever about to be lost, destruction will be immediate.

[Back]

Laplace: …

"This Drain Lab will be destroyed in 5 minutes."

Laplace: ...I was able to disobey an order. This…

And then… Everything goes white...Marco and Alice were already dozens of meters away from the laboratory when the ground under them fell down from the explosion, Marco picked Alice and jumped out from the hole using the falling debris as a platform, and the golden flash landed ear the border of the giant hole, then he put down Alice.

Alice: ...It seems like you're all finished.

Marco: Yes, the laboratory is gone forever…

Alice: At least we were able to save the prisoners, even if…

It looks like the machine's death brought a small tinge of sadness on Alice, but Marco interrupted with a disinterested look.

Marco: Don't weep for the stupid. You'll be crying all day. She decided to sacrifice herself, at least let her alone…

Alice: You're right… Let's go to the Forest of Spirits now.

Marco: Huh? Why? 'They found out already?'

Alice: Oh right… You were half-sleeping… Nevermind.

[Later]

Diane landed in an area in the north of the Forest of Spirits that Tamamo shown her. They hopped off and Marco said.

Marco: Alright, now Alice, show your smelling capabilities…

Alice: Fuck off! …*Sniff* I do smell magic here… But it's too difficult to find the specific location.

Marco: Well… There isn't any reason to be stealth now… Sylph, is ok if I make this place explode?

Sylph: NOOOO! It's my home!!!

Marco: ...Plan B, Chrome, come out…

Alice: So you found her too…

Both Marco and Alice turned towards a certain direction in silence.

Chrome?: ....Nya!

Marco: Jesus Christ, Chrome…

Chrome?: …

Then she sheepishly came out from the back of a tree with a giant coffin on her back, since she was a monster, she had enough strength to easily carry it.

Marco: I told you I needed her cooperation in future… Now, do you know anything about the laboratory?

He said the first sentence to Alice and the second to Chrome, who stopped being embarrassed and answered.

Chrome: As you two seem to already know, there's an important facility for the Heavens here… The one in charge of it is my sister.

Marco: SCP-049…

Chrome: It's La Croix! Not SC-whatever!

Marco: Well, I wasn't the one to choose a black plague doctor's costume and making Jojo poses!

Chrome: ...What's the "Black Plague"?

Marco: Just a dangerous bacteria… Don't mind it…

Alice: You were given technology by Promestein too, weren't you? I think you better tell us everything you know now.

Chrome: As I said before, she just gave me stuff without asking anything in return. I didn't even know who she really was yet. And to think my sister was one of her subordinates…

Alice: …

Chrome: I knew there was a small facility nearby. I thought it was just some sort of communication hub for them…

I snuck in there to see if I could find anything interesting. And that's when I found out that it was a Biolab that my sister was managing. It appeared to have facilities to study both living and dead bodies, and some sort of sealing device.

That's what you two are looking for, isn't it?

Alice: A sealing device… It looks like this is the right place.

Marco: *Sigh* More prisoners…

Chrome: Now, I think we can make a trade. You two don't know where the Biolab is, do you? But I know where it is, and how to get inside. So in trade…

Alice: You want us to take you to your sister?

Chrome: T...That's right. Don't get me wrong, I'm not powerless myself! But infiltrating that place alone… Makes me uneasy...

Marco: I really hope so, if I take a dead weight behind then I'll use you as a shield…

Alice: So you accept?

Marco: Either that, or I'll make a nuclear bomb with my bijuudama. But I'll accept it to a single condition.

Chrome: You think you are able to say anything?

Marco: You think I won't threaten to punch you here and now until you will bleed?

Chrome quickly backed away with a yelp and trembled a bit.

Chrome: A-Alright… But don't exaggerate…

Marco: Relax, it's something small… If there is any angel enemy, or something with angel genes, then I'll kill her. No exceptions.

Chrome: Huh, just that?

Marco: Yes.

Chrome: Then it's alright. The entrance to the Biolab is right in front of you! Though you can't see it…

*Ding*

*Special Quest: Escort Chrome to La Croix.*

Marco: No shit Sherlock?

Chrome: Spi! Rit! Open it up!

Before the ghosts appeared, Alice hid behind Marco.

Spi: Ahaha, got it!

Rit: Alright, here we go…

Chrome and her two ghosts made a strange hand gesture together… And suddenly, a huge Luigi Mansion-style mansion appeared before their eyes.
