I'm not sure...but indeed they were inhumane...I know first hand.

Not sure I understand what this Plume of Dusk is, but the only sure-fire way to get a persona that I know of is to face your own shadow in the TV world.

I've only used it 60+ times (not cheating inevitable death)

@Yu-Narukami a Plume of Dusk is the core of my personality module; my heart. Its what allows me to have a personality, ego, and thus persona.

@-Labrys-

...Oh. I'm not quite sure what to say. It sounds like you endured quite an ordeal, and I'm sorry that you had to go through that.

One of the main reasons I'm asking is because, despite the fact that Command has reassured me that they won't do anything cruel... I'm not convinced they won't try similar methods given how little we know. I want to prove there's a better way so we can avoid the tragedies of the past.

It's very reliable though

@Yu-Narukami

Facing one's own shadow... You're talking about the manifestation of the repressed parts of one's ego, right? Well that sounds like a solid plan, but we're not quite sure how to access this Cognitive World. It seems we currently are not capable of accessing this TV World, as when one of our units tried to do so, she just broke a monitor.

The biggest thing is to not make unit fight each other. They need tah fight somethin, to get stronger and learn, but just not each other. That was the cruelest part; killin my sisters. They have hearts, hopes, dreams too. They're more than just robots. More than just weapons!

Robot death battles sound like fun

The Plume of Dusk doesn't not inherently grant an ego. It has to be fostered and grow. So they can fight their shadow, yes, I did to get mine. Just they have to learn and grow a personality first.

That's so cruel of @MakotoYuki14!!

@-Labrys-
Don't listen to him sis, he's just a door.

O-okay sis..

@-Labrys- Yeah, to have a YoRHa Unit kill one another needlessly, it's just too cruel to think about...

Hold on... if what you're saying is true then... there's no need for any replication of the experiments of the old world! As long as we simply install a Plume of Dusk into a YoRHa Unit, the Persona ability should manifest on its own during our fights against the machine lifeforms! I have to go tell Command!

Make sure they interact with each other too! Binds and interactions are necessary, as they help solidify the concept of emotions.

@-Labrys- Bonds huh... I wonder if... ah. Never mind... I should proceed with the mission and report to Command.

If you need help entering a TV I could always lend a hand.
