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.

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.
