The Jugol Series is a series of songs by Caprice. It is currently made up of 18 songs sung by eight VOCALOIDs, two UTAUs, and one human singer. 15 songs are uploaded to YouTube, 3 songs are uploaded to NicoNicoDouga, and 4 songs are uploaded to Piapro.
The series is about a world in which there is something known as "Ludzkość." "Ludzkość" is the Polish word for "humanity." Ludzkość is apparently destroyed in an incident involving a scientist trying to cure the fear of fish. The series is still active.
The Jugol series is divided into eight parts. Part Zero (Dramas of the Gods) and Part One (The Beginning of the World) currently have no songs.
The mysterious person from before prepares to go to the girl as a new character sees her off. The girl's mother is then worried about the girl's mental health, while the girl is completely sure that she is okay.
The man from before, having apparently caught his loved one's illness, tries to tell about his plight. Nobody believes him except for a mysterious group of individuals simply known as "the Council of Cawauso." ("Kawauso" is Japanese for "river otter.")

A man who tested Project S seeks a cure for his new affliction. He calls 911 some time after, which leads to the following conversation.
"911, what's your emergency?"
"Sorry, but I'm an...an...an otter!"
The beginning of the video shows a dictionary definition for "hallucination."

Caprice, Lemmings (grammar-checking)
The man from "fallout" and "The Council of ????" and his loved one talk about the current problem at hand. The loved one says "Because of you, I'm a fox! We will all become animals." This is most likely a delusion.
The people from 最終の「Ｓ」の視察 and 変死のアゴニー talk about what has happened to people who were born after it happened. The Japanese title appears to be that of "最終の「Ｓ」の視察" put backwards, while the English title is "Lutrine Revelation."
