## Kunihito's uncle's notebook

   There is a old notebook written by the uncle of Kunihito, located in the Okinaga residence.

It is conserved and protected in a large box under the altar Kunihito built in the basement, along with several other documents. It is quite old, and is covered in tape.

It contains detailed information and records about the strange phenomenon going on in *sweet pool*​, as well as a map.

Kitani reads it even though he is not allowed to, in order to understand the strange behavior and words of his boss Kunihito as well as Kunihito's son whom he takes care of, Zenya.

### ​Notes

The notes are organized into different parts:

* In regards to "inner beings".
* Regarding Osu.
* Regarding Mesu.
* Regarding the Pure Breed.

Here is the notebook's exact retranscrition.

I was allowed to walk alongside "Them", the single blessed human. Therefore, I will record the truth that has been passed down for eternity per my wishes.
 In regards to "inner beings".
"Inner beings" were originally part of "him". I will explain that later on. "He" is the being of the organization called "Onnushi".
We're not sure where "he" exactly came from. We can guess that he appeared in the Meiji era, based off the fact that "The Free Peoples" organization was based around that time.
"He" originally has a human form, bringing the people to faith with his flesh... As followers consumed his flesh and took him in to live inside them, our numbers would increase.
 Regarding the hosts.
I will now refer to the ones chosen by the Pure Breeds as "hosts".
"His" flesh is like any organism, with the instinct to breed, and lives in a human's abdomen. Humans that are made "hosts" are transformed into either Mesu or Osu.
If they were not chosen to be such, in many cases, there is strong rejection between the mind and body, and causes their equilibrium to fall out of place.
 Regarding the Osu.
Osu are far more frequent than Mesu. They release a pheromon that attracts Mesu, one that can be described as a sweet scent.
Osu have a high ration of the flesh, leading to the Osu having a generally high regenerative ability. This is a power Mesu do not have.
The Regenerative Abilities - it is a bit surprising.  Whether it be a wound or a sickness, their recovery ability is powerful.
I cannot ascertain how powerful the ability itself is. With just a cut from a knife, the wound easily closes.
So what about guns?
Bullets lodge into the body, wounding both muscles and organs.
Assuming it penetrates, they can be saved by treatment, but in the case that it goes untreated, the victim usually dies of blood loss.
The blood continues to escape, perharps at a quicker rate than the regeneration rate. I've taken the fact that hosts were originally human into great consideration, so their body not lasting makes plenty sense.
So killing them with guns is a possibility.
 Regarding Mesu.
Mesu are extremely rare. When Mesu and Osu copulate, the Mesu can produce a Pure Breed. If they have intercourse with a human male, it is possible for them to produce the flesh.
In order for a Mesu and an Osu to call out to one another, both emit pheromones. The aroma has a strong effect, and highly sensitive humans have been recorded to react to it. When a Mesu makes contact with an Osu, the Mesu conjures a certain kind of phantom pheromone.
They "stamp" them. This "stamp" is to let the Osu know of their existence, something that only "hosts" can see.
 Osu and Mesu. They're like animals.
In summary, humans with a "living being" inside of them that successfully lived are "hosts" which are divided into Osu and Mesu.
Why Osu and Mesu are divided. It's for breeding purposes.
 Regarding the Pure Breed.
Pure Breed are born in the event when, hosts, a Osu and Mesu copulate. They can be distinguised by their crimson colored eyes. The chance that a Pure Breed is born is heightened when the Osu and Mesu have a high affinity with one another, but it's still extremely low. There has not been one born for decades. When the Pure Breed is born, both the parent Osu and Mesu die.
Pure Breeds are different from the "seeds" Mesu born, it has the ability to foster itself inside of humans. Again, Mesu distribute "seeds" after copulation, but a Pure Breed's seed has the potential to to be directly absorbed into the human body without the need of intercourse.
Pure Breed can freely control "planting seeds" and "stamping" as well as hold a high regenerative ability. Their pheromones are stronger that any Osu and Mesu's, with the ability to captivate even normal humans.
The last living Pure Breed was protector of the Okinaga household.
However, in the past, two thirds of his body was lost, lowering all of his abilities to nearly zero.
Pure Breed. From their features, it's as if they are to be the leader.
In the end, are Osu and Mesu only alive to birth the Pure Breed?
 Why did I choose to record this way? I just jotted it all down. My utmost intention is to protect the "inner beings"  and "him". It seems that along the way, it became a fascination.
"He" was actually a beautiful young man. I only saw him once during my childhood, but his elegant face and deep crimson eyes left me breathless. When "he" came up to me, he gave me a soft grin.
However, "he" was not a low existence like myself, one that you could just meet at will. Seeing "him", the embodiement of the perfect man, was a once-in-a-lifetime chance.
The next time I saw him was during the time of the revolt. A time passed, peoples' faith in him disminished, and members had plotted to kill him in order to create a Pure Breed.
The revolt nearly destroyed the organization. However, I took advantage of the situation and secretly went to "him". I wanted to see "him" and his divine beauty one more time.
 I knew that it was definitely "him", but this time he was a mere large slab of meat.  No head, no limbs, nothing resembling a human at all. He was only a shadow of himself after he gave so much of his flesh to the followers.
And then, the non-followers lit a blaze. They wanted to burn him away. When I realized that, my body moved on its own. I took "him" in my arms,  and frantically ran through the crowds of people.
 And from then on... I was determined to continue to protect "him". After the non-believers were eliminated and the organization's representative changed, it was acknowledged that the Okinaga household would guard "him".
I have left a map which includes the sacred area in which he is enshrined. All rituals have been held there.

### Map

The map left with the notebook is made out of a thin paper; it is a map of this town. There's a place in the lower right corner circled in red, that indicates where "he" was enshrined: the Komanami Private Academy.
