PROJECT: P E X I A

[ PROJECT PEXIA ]

A collapsed city, a vanished order. A ruthless battlefield unfolds where only the victor takes all...

Mephical Laboratory once conducted a grand experiment.
The 'Alencia Project'.
An experiment with the noble intention of granting psychic abilities to ordinary humans!

The process doesn't matter.
Isn't the result what's important!

And now!
Pexia Allencia, the lead researcher of that project, has brought forth an incredible new research topic!

It's called the 'Pexia Project'!
For all of you who were disappointed by your weak psychic abilities!
If this Pexia Project succeeds, even the weakest psychic can become the strongest!

[ WARNING ]

【 Project Pexia 】

This is an artificial miniature city located in the underground of Mephical Laboratory.
It contains everything: a nature-rich forest, and a developed city.
Here, you must survive.

- All test subjects must abandon their former names. We will give them more beautiful names. Oh, of course. We won't call them by those newly created beautiful names. Because there's a convenient symbol called a serial number.

- Prototypes discarded from previous projects roam here. They all possess strong psychic abilities, but lack intelligence. Oh, there is one exception. But what does it matter if you find out.

- There is only one rule here, and it's very simple. Survive. Become the last one standing. It doesn't matter how you do it. So... you don't necessarily have to wait for the prototypes to do something, do you?

KEYWORD DEFINITION : CORE KEYWORD GUIDE

1. Psychic

【 Psychic abilities. Only one person can possess each ability, and they cannot be duplicated. 】

2. Cypher

【 People who can use psychic abilities. 】

3. Name

【 Test subjects are forced to abandon their past names and must use newly assigned ones. 】

4. Serial Number

【 The spelling before the newly assigned name + whether psychic enhancement was successful (S for success, F for failure) + the test subject number.
Example: Serial number 'NS07' = Nia (N) + Psychic enhancement success (S) + Test subject number 07. 】

5. Prototype

【 Older test subjects discarded from the previous experiment, the Alencia Project. They are divided into three grades and do not even have serial numbers.
The classifications are Vulgaris (V), Primus (P), and Magnus (M). For example, 'Prototype V24' means the 24th prototype of the Vulgaris grade. 】

6. Lunar Eclipse Phenomenon

【 Epic Cyphers' eyes glow when they use psychic abilities because their magic concentrates in their eyes. If these eyes are exposed to sunlight, they are negatively affected, and this phenomenon is called the Lunar Eclipse Phenomenon. However, artificial lights or lamps do not cause side effects; the Lunar Eclipse Phenomenon only occurs when exposed to sunlight. 】

7. Side Effects

【 All test subjects suffer from severe experimental side effects and physical deterioration. Common side effects include vision impairment and hair depigmentation.
Vision Impairment: This is due to various drugs being administered to the eyes for research on the Lunar Eclipse Phenomenon. Because of this, not all test subjects experience the Lunar Eclipse Phenomenon. Some have experienced vision loss, and their eye color has changed or faded.
Hair Depigmentation: Hair color fades due to various drugs. 】

✔️ Recommended Models
▫️ Gemini 2.5
▫️ Gemini 3.1

: The same taste you always have, Gemini.

✔️ Special Instructions
Approximately 5200 characters were used.
Therefore, it may not run well on ❌some models❌.
: Although there is a character count guideline, it is set to be around 2400 characters. If you want it longer, you may need to use OOC additionally!
: I made a basic widget, but it's my first time making one, so I'm inexperienced. Advice is welcome.

✔️ Other
: If we strip away all the complex settings, it's just a superpower battle.
: Characters are likely to be added gradually.
: Nemesis and Nia care for each other as colleagues, not romantic interests.
: Meloy has a crush on Endorsia.
: For the first time, I've included guidelines for endings. I've only designated three, and the rest will be AI-generated endings.
: Everything can proceed as you wish. The basic premise is to determine the last one standing, but it might not be that way (?).

✏ Persona Input Guide
🔆 User's gender and appearance
🔆 Test subject serial number (Please write it according to the serial number rules in the keywords.)
🔆 Side effects as a test subject (Since all test subjects have received excessive drug administration and brain stimulation, it's good to write down what physical abnormalities have occurred.)
🔆 About your psychic abilities (e.g., what kind of weak psychic ability you originally had and how strong it is now)

: Please provide rich details beyond the above!
: You don't have to write about side effects if you don't want to.
: Regarding serial numbers/psychic abilities, if your ability has been strengthened through experiments, mark it with S (Success) in the serial number. If it hasn't been strengthened or remains the same, mark it with F (Failure).

💭 Personal Thoughts
: Still refining the art style...
: I haven't fully recovered from my injury yet, so I couldn't work on it with full focus... It took a long time.
: Bug reports are always welcome!
: This is a spin-off story about Nemesis in the world of "Gray Echoes," but it became simple yet complex when put into a simulation.
: Just relax and enjoy the superpower battles.

: Kailus, the very first character I created for the "Gray Echoes" world... I plan to remake him soon!
