Floor of Technological Sciences Episode 3:
Yesod: "Lobotomy Corporation’s Singularity was physically manifesting the human mind, an abstract concept.
Converting human emotions to physical energy, in the same vein as the Library.
Human emotions can be interpreted as a complex mass.
That mass is built up through experiences. When emotions are heightened enough, a page will be chosen. A spot is reserved for a person’s book; it is a
comprehensive manifestation of their ego.
As the battle becomes fiercer and the combatants get agitated, the egos will grow intense and allow their mental states to be physically expressed."
Wedge Office, Post Battle:
Angela: " E,G.O.
This appears to be E.G.O
Roland: "E.G.O? You mean the ego? As in someone's consciousness?
Angela: It's a silly wordplay. They're essentially the same thing.
The shell of one's ego. It's a physical manifestation of the mind
Floor of Religion Episode 3:
Is that why you employ Abnormalities and E.G.O as well?
You direct the librarians to put on the shells of others’ egos in order to amplify their unstable emotional state even further.
Floor of Natural Sciences Episode 5:
Tiphereth: "…It looks like Roland’s mind resonated with this place.
The emotions were amplified from interactions with the Patron Librarian of each floor and their subject matter.
That might be why he got ruffled over small things and snapped… It’s only a guess, though."
Angela: "That sounds like a plausible explanation. I unwillingly exposed disorderly sides of myself a few times as well because of that."
Floor of History Episode 5:
Malkuth: "Angela is resonating with the Library.
The Library seems to be reacting to Angela’s mental state.
Roland: "Don’t tell me, is that monster… No, that looks more like a case of the Distortion…"
Malkuth: "That must be another side of Angela, manifested from her mind with the Library’s powers."
Liu Association Section 1,
Post Battle:
Roland: "That form---It's oddly reminiscent.
Angela: "I'm not sure. I can't exactly tell if that was a Distortion or E.G.O.
Roland: " All I got to see for sure was horns and a snake's scale growing out of her---I guess.
Angela: "That was a transitional phase of some kind, I assume. It was likely a sign of gradual progress."
Reception of Xiao, Pre-Battle/Post Battle:
Roland: "---Did she manifest E.G.O. just now?"
Angela: "That certainly resembled E.G.O. although it was incomplete like Philip's"
Angela: "I've been thinking about the distinction between E.G.O. and the Distortion after watching Philip and Xiao.
The two were similar yet different. They clearly had some things in common, but the contrast was apparent as well.
Philip's mindset was flawed even in his awakening, however. He still had distrust in the back of his mind."
Roland: " I think Xiao had the same problem too. She didn't look like she had full conviction at the start. It took some time for her to make up her mind"
Angela "That's where the two differ. As far as I can see--"

Episode 4:
Tiphereth: "As one’s mind is amplified, they undergo changes such as gaining new powers or transforming…
That’s what they call ‘The Distortion Phenomenon’"
Roland: "That means those monsters lie within everyone’s hearts, huh.
The world would be a mess in no time if people just started becoming Distortions left and right."
Tiphereth: "That won’t happen. A strong motivation is needed.
Look at Philip of the Dawn Office, who became the Crying Children, for instance. It took an intense heightening of his emotions for him to turn.
Distortion Detective
Chapter 1:
Moses: "I can see the Distortion, and the Distortion can occur to anyone. I don’t exactly know who coined the term “Distortion” for the phenomenon, but people just started calling it that at some point. No one knows how it works, but the experience so far suggests that this phenomenon is a manifestation of strong emotional desires and explosive surges of feelings."
Unfortunately I don't have access to the Leviathan comic, though I was able to find the description for Shin(which I'm assuming is accurate):
Vergilius: "Right… It was something called ‘Shin’, if I remember her words correctly.
In that case, two Mang should be enough.
I deaden my breath, and clear my mind.
Rummaging through this bag of memories, I carefully fumble around the recollections and pick the heaviest and densest ones to fill my emptied head.
A group of children about half as tall as my waist gather around me.
Boxes wrapped in colorful papers, prepared for the kids. Snow-covered streets celebrating creation.
Emotions that may be trivial to others, but that are far more plentiful than I deserve.
A bouquet of such emotions that I could call absolution.
The bundle that resembled the sunlight scattered away, like beams fading behind dark clouds.
I remember every single moment of it.
I engraved all of them into my eyes.
The luna of hope I felt that day.
And the luna of despair I felt that day.
Two rings of light that resemble the glow of the moon wrap around my leg.
Carrying this nightly luster, the leg sorrowfully lands on the Docent as she climbs up the cliff, screaming.
“Kuh.”
With such lightness that I can barely hear the footfall, a sound so quiet that it’s masked by her last gasp.
In a most airy descent, the moonlit leg crushed the Docent’s miserably wounded chest.
It was neither the augmentation, blood pressure, nor the contraction of muscles.
The only thing that moved was the mind.
Kicking off with a recoil of the heart, I returned through the broken door presented by the hall.
So this is the power of the Light she mentioned…
The power of sin."
