Author's note :
Hello, hello, here's a new story here, potatoes !~
This time, let me show you a GuP x Portal crossover... The idea came to my head right when I first played the game again after not playing it for long. I was thinking "Why wouldn't I rerun the story of Portal 1 but...with GuP characters ? That would be fun.".
I really hope you'll like it. I'm also translating the epilogue of The Cats now, and maybe I'll write some death one-shots because I love writing death scenes.~

I keep saying it, but for those who have never read any of my stories, English isn't my first language and I try my best not to make too much mistakes. If you spot some, please tell me so I can correct them.

Enjoy, potato !


PROLOGUE : Test Chamber 00


"Maruyama Saki!"
"No," Aya said. "Not Saki."
"Saki Maruyama."
"No!" Yuuki protested. "Saki can't leave us!"


Saki Maruyama opened her eyes.

She was in a strange room. The ceiling was gray; everything seemed to be made of glass and concrete.
Where was she? What was she doing there? How did she get there?

Talking of glass, there was also some just above her head; no sooner had she regained consciousness, it opened like two doors, releasing the girl who rose.
She came out of what appeared to be a stasis bed and looked around. She was in a very small space. There was a toilet seat near her.
She was hearing music while she was awaking; turning her head, she realized it was from a radio placed on a shelf by the bed.

"Where did I end up?..." she thought.

She began to walk round several times in this tiny room.

She saw herself in the reflection of the glass; she was in some sort of an orange cloth which reminded her of the members of the automotive club in Ooarai, except that it had short sleeves, her school uniform underneath, and weird, long and thin things attached to her knees, going along her calves without any contact with them and touching the ground.
She noticed, turning to her side, that she had a symbol on the back side of her jacket; however, she could contort herself in all directions, she couldn't see it in an entiere view.

She continued to explore her little cell until a female, robotic voice was heard:


"Hello and, again, welcome to the Ooarai Science computer-aided enrichment center."

Saki startled. She had heard that voice somewhere, but more human and less robotic.
But to whom it belonged, that was the question.

"We hope your brief detention in the relaxation vault has been a pleasant one", the robot said. "Your specimen has been processed and we are now ready to begin the test proper."

"A test?" the girl whispered, a little confused.

The voice continued:

"Before we start, however, keep in mind that although fun and learning are the primary goals of all enrichment center activities, serious injuries may occur. You're not allowed to resist, otherwise you'll finish in the same way as Ishida Mitsunari when he had escaped after the defeat of Sekigahara."

Saki felt uncomfortable. Irreversible damage? But at which level? Where? At what intensity? And with death threats and a reference to someone she didn't even know?

"For your own safety and the safety of others, please refrain from touching anything-"
"But if I'm not allowed to touch anything... how do I go away from here?" Saki thought, not really understanding what was happening.

A metallic buzz rang and the voice seemed to change. It was deformed and the sentence it said in bad Spanish was quite meaningless.

"Por favor bordón de fallar de muchas gracias de fallar gracias..."

Another glitch seemed to strike the robot and stopped suddenly, letting it speak again.

"Stand back. The portal will open in 3... 2... 1..."

A strange orange thing appeared in front of Saki. It faced another part of the room; moreover, the freshman was able to see through the other, which was blue-colored.
She got carefully her hand in and saw that it was appearing from the other side.

"Curious", she told herself. After her hand, she passed the other, then cautiously, she went in with her whole body and realized that she had got out of the glass cell where she was.
She knew that teleportation could exist in the distant future, but she had never expected to get from one place to another using these odd portals.

She went out through an open door and found herself in another room.


The chamber was colorless, light grey, made of concrete as the first, and there was further a door, a strange glass tank and a big red button the ground just before her.

Saki went up on it; the door opened. She went down; the door closed.

A cube fell from the glass tank which opened; the girl came to it and examined it.
It was grey, with prominent ridges; on each of its faces, there was a blue circle with a symbol that was most likely the same as the one she had on her back; a black coin with lines which made it look striped, like the aperture of a camera lens.

She tried to carry it ; it wasn't very heavy. She thought for a long time then about what she was supposed to do with it, sitting on the cube.

"Well... if the door opens when I'm on the button, it will open if this cube is on it," she thought.

She went down, took the item, advanced to the button and put it on it; the weight of the cube activated the door, which opened.

The hallway behind it was leading to an elevator; just before it, an immaterial coating sparkled.

Saki got into the elevator. Its doors closed. The voice sounded again:

"Perfect, little one. Please go into the chamberlock after completing each test."

She felt that she was beginning to rise.

"I would like to draw your attention to the field of incandescent particles before each elevator. It's an Ooarai Science Material Emancipation Grill. It will disintegrate any unauthorized equipment that passes through it -for instance, the Ooarai Science Weighted Storage Cube- so the test subjects won't be able to bring anything from the test chamber with them."

Saki always asked herself the same question; who was that voice she managed to recognize without being able to put a face on it? Who was it? She was sure to have known someone with the same vocal timbre, the same way of speaking. It seemed strange to her. She didn't know who it was, but on the other hand, she knew, and this contradiction was bothering her.

She waited until the rise was over and when she got to the next floor, the elevator doors slid and she found herself in another test chamber.
