"Hello! Do you hear me?"

"Just couldn't not notice you, well, floating here. In the middle of the Grand Differentiation Valley!
...
Who are you?"

(He scans for magic. The magical background is increased as usual for the valley. Nothing about Kaworu is detectable as magic to Raz's senses. Which is very weird, in such circumstances.)

"The Angel of Free Will."
Kaworu keeps staring in the distance, barely reacting.

"That implies that angels are 'of' something. And that you are the only one Of Free Will. Which doesn't fully align with my understanding of angels. Are you some sort of...Exarch? Or Manifestation?"

"I...am a manifestation."

"Were you waiting for me? Are you sent to deliver a message, about my current mission, or what is happening generally?"
After all, freedom and messages seem, in the context of divine beings and manifestations, to be...wait, no, wrong metaphysics, nevermind.

"Not to my knowledge.
I had no intention to meet you, or tell you anything. Nor any other intention.
But fate often works regardless of our wills."

"You would probably know, being a manifestation of free will.
Why are you here then? What are you doing? Unless youre just, you know, meditating, thinking about life."

"I do not know why I am here. Or anywhere else. I do think about life."

"Why would you..not be anywhere?"

"I died. And did not expect to continue existing. Not in a physical form capable of...sight, and speech."

"Huh. Well, that's not that rare an occurrence in the omniverse. Relatively speaking. Even has three-syllable words that describe it, and such! People have many theories about why that happens. Though I personally think most of them are nonsense."

"How did you die, and what all did you do, or wanted, before?"

"I was created with great power, and no set course. My choices would determine the fate of the world. My kind, if able to fulfill their purpose, would destroy humanity. The strongest of them, I chose to die rather than let that happen.
I do not know what I wanted, exactly. Love. For Shinji, who fought to save humanity. Fulfillment of prophecy, but it would have been fulfilled either way. Freedom, to choose unexpected actions, go against my nature. And to die."

"Don't know who this Shinji is, but am totally in favor of saving humanity. How could you go against your nature, though, if your nature is free will? Isn't that paradoxical?"
He assumes it all happened in a different world, if happened at all. Isekai is evidence of favor. And he doesn't expect to get clear answers on interdimensional geography from this guy. He barely understands it himself.

"The nature of angels, as of all creatures, is to survive, by destroying their enemies. Doing so would have been the simplest course of action for me.
I was born with the destiny of freedom, so I could choose. According to the prophecy. It is paradoxical. So I was never told what my fated choice is. Only that this destiny exists, and I had the freedom to decide, and what the prophets themselves wanted me to do. I acted against their desires, in the end.
But maybe they told me lies. Or were mistaken. There is no way to tell."

"They could have lied about the nature of angels! Considering this is not at all what I think the word 'angel' means. Though words are always flawed. And...actually, do you notice the language you are speaking in?"

"Words are the expression of thought. I do not need to learn a language to say the right words."

"Here you go then, the imperfection of automatic translation through the noosphere. I think.
What exactly do you mean when you talk about angels, though? I want to understand."

Passing through the barriers between souls is easy for the Vessel of Adam. Thoughts flow directly between the two speakers:
The Seed of Life, falling to Earth. Shattering into pieces. Each continues living. Endless energy flowing, constantly changing, shaping itself into unimaginable forms. The ground shaking, space bending into impossible shapes. All seek to return to the source, be combined together, a process of mind-shattering power.

"Fuck! That was unpleasant. You know, people who aren't as enlightened and mentally stable as me might consider that 'horror beyond mortal comprehension', or something like that. And showing it to them as a hostile act!"

"You wanted to understand."
