Although I prefer to leave Dzu to their own devices, I could not help but send one of my students to analyze their sword. 

It is a remarkable device. I do belive it is directly connected to a sub realm. The energy it emits comes from that realm. 

How they managed to collect and fill that realm with such energy I do not know.

I do believe I know the source, as the potency of it is only matched by one other.

I do not fear Dzu, but I am wary of that weapon.

Still, they are very useful and make my own tasks easier with their presence.

-Notes by the Demon Master, The Head Master, collected by the Demon Master Bael

The sky is endless here. I feel like I will fall up into it. Why does it need to be so big? What's out there?

I'm already so small, I don't need to feel smaller. I try to get used to it, but a part of me wants to find a deep cave and disappear into it.

Hungry and alone, and scared. Maybe when I am an imp things will be simpler...

-Masterless Demon Fetan

She was born a healthy weight, a healthy size, all red and wrinkled and sticky... and I am filled with the strongest sense of love and despair.

I did not know it would be this way, to feel like I am at the edge of a great and endless pit.

She is so infinitely fragile. I have woven every spell of protection I can, and the doctors assure me that she is hitting every milestone, and Beckett is always here and always so full of patience... but I did not know it would be this way.

I take care of a CITY! I have defeated DEMONS AND MONSTERS! And yet. And yet!!

I cannot face what would become of me if something was to happen to her. And yet I cannot look away.

-Diary of Queen Augustine

My love and my anger are entwined, both cause me pain and yet are my only reason for continuing.

I am worried that one of them will snap, and the other will not be able to sustain my actions any longer.

I know I need more than this. But this is all I can manage, at the moment.

-The Slayer Nina

It disgusts us how wasteful Demons are with their finite, precious, infinitely valuable energy.

Not just the common Demon, for that we would understand. Even though they have so little they do not have the COMPREHENDING of how to truly utilize it. They dribble and drain it away in a thousand small ways. The tell-tale glow in their eyes or around their bodies of a slow leak, of energy forever lost on pointless expenditure. (We have witnessed lesser Demons use their energy to FLY instead of WALK what would have been only a few steps up!)

But even the Masters waste and spend their energy as if it is INFINTE. Every drop must be used expeditiously and to a purpose. Instead of a beam of raw power, use instead a line with which to dissect. 

Use energy to deflect energy. Use energy with the understanding that the pressure it exerts is its force divided by the area it connects with. Use the minimum amount needed to finish the JOB.

Do they not understand the difference between a Pillow and a Pin? Which would you rather lay your heads upon...

-Internal Memo from the Demon Master Buzhum

My thoughts are SO LOUD I can't shut them up but I'm doing EVERYTHING that I'm told and Saint Vau likes me at least I LIKE HIM! I REALLY like him. When I'm around him I feel more grounded. I'm not crazy but I feel sane. I held his hand yesterday. I only realized that the voices had stopped roaring when I did that. 

The Doctor said that it's normal and to not worry. To just focus on what we need to accomplish. Don't let my fears get in the way don't let my ANGER get in the way!! GOD WHERE IS ALL THIS ANGER COMING FROM??

I need to see Vau. We can kill something together. That's the absolute best way to calm it all down. To have no thoughts at all.

-Demon Slayer Gerda

Through hidden informants I have learned that the play "The Entire and Complete History of Demonkind" has a runtime of several hours and three intermissions during which the audience is asked (forced) to give (positive) feedback. 

While some of the play is clearly built on deep and even hidden truths, much of it is symbolic and/or terrible rhyming verse. 

As the play progresses things become increasingly skewed towards the viewpoint of the Demon Master Sangui, and the final act entirely revolves around her gathering all Demons and Humanity to her, finding a way to merge with them all as a kind of liquid, and then ushering a new golden age with her as all things.

Truly horrifying and hopefully entirely delusional.

...There was a bit with a comical Angel Dog that I could not help but laugh at, I am sorry to say.

-Notation on Demon Master Activities by the Demon Master Dzu

Sooo... he's gone! Is that bad? Does it matter?

-Ms. Ferret

It does not matter any longer. As long as we keep him away from Gerda, he can do no harm. Even if they come into contact with one another, we have solutions.

-The High Angel

Huh. You sure he can't do anything?

-Ms. Ferret

We allowed him leniency out of respect, and that leniency was rejected. We will not be so respectful when we next encounter Mr. Crow.

-The High Angel

Although extremely hard to procure, it has been shown that young Demons are far more Magica than they are flesh.

Imagine a delicate and ripe fruit. Although it gives the appearance of solidity, if you squeeze it will yield completely.

As a Demon ages it is able to compact and refine its own energy into an increasingly dense structure. 

Still, even solidified Magica is still Magica, and in turn it is weak to disruption by Magica. 

The purity of Magica needed does increase in relation to the refinement of the Demonic form.

-Notes on "Demonic Flesh; Methods for Efficient Vivisection" by the Head Scientist Priest 

See the thing is, Kassandra should have never opened her mouth. I think then... yes. Then she would have gotten what she wanted, perhaps.

-The Snow Queen

(several minutes of laughter follow the above statement)

Pleasure and pain can only be measured relative to your own reality.

For those that have suffered immensely, a great pain in others will be dismissed as insignificant.

For one that has never encountered tragedy then even a small upset can be insurmountable.

To understand what another is experiencing, we must see the moment through the light of their past.

The same event encountered by ten different people will have ten different outcomes, not all measurable until much later.

Reality must remain subjective, lest it be taken from you.

-Writings by the demon Philospher Fizzlestatros (widely derided as a fool)

What do you think about the "God" that used to run things, Kay?

-The Snow Queen

... I don't really think much about her? The stories never really made sense. She couldn't have made the world only several hundred years ago. It is possible she was a massively powerful magica user though!

-Kay

She did "make" this world, Kay. And magica is a gift left behind by her. But you are right, she was no true God.

-The Snow Queen

Uhh. Wait she was real? Huh! Wow. Does that mean-

-Kay

To be a TRUE God you must be more than a human. You must abandon all those weaknesses people hold dear. You must know the Future, and it must bend to YOU.

-The Snow Queen

Uhm. I don't know if that's strictly true for all Gods, I've read about a few that were pretty flawed, but I see what you're saying...?

-Kay

Further testing shows that patient Gerda cannot be equipped with the Halo. Multiple energies are active in her and will lash out at any attempt to insert the spinal connection core. Recommend giving her no authority beyond that of a blade.

Patient Vau has shown immense progress with no more erratic actions. As the Halo is installed it cannot be removed, but patient Vau may be given increased clearance and responsiblities. 

Patient Iota is impeccable in her following of orders and behavior, but is disappointing in her energy accumulation. She has now fallen behind the EVs, although her technique is still better.

Patient Mu has increased greatly in both energy and technique, but must be used soon or lost. Temporary measures have been taken to gain more time, but these measures have capped her energy output.

-Private Medical Update, sent to The High Angel

Do you think there are Demons that live in the human world, alongside humans? More or less getting along?

-Cezar

Uhh. No? How would that work.

-Scrambles

Well I guess you'd eat a few here or there, right? But mostly you wouldn't! And then you could have like, human friends you would DEFINITELY not eat! That would be fine, right?

-Cezar

... From what I understand about humans, they have a kind of "zero eating humans" rule in place.

-Scrambles

What if it was only bad guys or something?

-Cezar

Yeah I think they don't even eat their enemies. Sorry buddy.

-Scrambles

The Unsanctified sleep deeply.

Rho, Pi, Xi, and Lambda are not saints, and they are not demons, and they are not humans.

Their bodies have continued to change in ways unlike the Sainted. Perhaps because a human consciousness is no longer guiding the energies within them.

I hope that we do not need to use them, but they will be if the cause is great.

It is interesting that all four of them have lost their eyes in the physical shifts. Inexplicable.

-Notes on the Saintification Process by the Head Scientist Priest

Sometimes it's like my Halo is talking to me.

-Empty Vessel 1

Mine just drools. I get nervous that it's going to bang on a door frame and I'll die.

-Empty Vessel 2

No they are very tough! As tough as us, I think. But it does feel weird to be wearing "yourself" outside of yourself. Vulnerable.

-Empty Vessel 1

It's like the Angels wanted to give us a weak spot or something! Hahaha!

-Empty Vessel 2

Hahahahahaha!!

-Empty Vessel 1

The High Angel has requested that all Walled Cities make every effort to get not only criminals and "those who have sinned", but ordinary Citizens, to commit to the Angelic Sin Removal Ritual.

To facilitate this, we are using high profile Citizens to go City to City and promote the efficacy of the ritual, and showcase the amazing effects.

See if we can put together some kind of fair or parade, that tends to bring people out that otherwise might not partake. 

He says we are in the final weeks of the ritual, so we must move quickly on this.

-Meeting notes from the Council of Edges on "Further Inroads With Angels"

Sometimes I like to give it a snack.

-Priest 1

What? The Demonic Flesh amalgam??

-Priest 2

Yeah, I mean, it's always writhing and in distress! I figure it might appreciate it.

-Priest 1

Do NOT feed the APOCOLYPTIC end times BEAST!!

-Priest 2

Hey we don't have to be mean...

-Priest 1

... I also sometimes give it treats.

-Priest 3

They are the stories we are told as children.

So beyond belief that that they cause only a thrill, a delight.

Until you hear the tales that are not fiction. 

Until the day comes that you see one truly, and it sees you.

And unlike an animal, or a monster, it knows you.

It has heard stories of you, as a child.

And those stories caused it to thrill, to delight.

To Hunger.

-Reflections on Demons, by an unknown poet

I think my name can confuse people, although I obviously smash, I mainly employ nearly invisibly thin layers of demonic energy. When I send these out at high speeds the edge slices through my enemies on contact. Sometimes the slices are so precise I have to "smash" them for my opponent's body to even realize it has been cut! Still, attaining that level of precision is not easy, and every day I practice mindful energy control to maintain cohesive ability.

-Smashmaster

GHHHGHHHHHGH!! GKKKGK!!!!! ZZZCHHHHKK. ZHHHCKKKKKKKKK!!! LRGGHHHH!!! Ghrnt.
