Nokkers

Nokkers (ノッカー), also spelled as Knockers in Kodansha's simulpub version), are mindless and "violent" creatures that were created to impede Fushi's progress in preserving the world. The Beholder named them such because they "knock on the doors of Paradise, seeking its destruction."

Their ultimate aim is to "release" all human beings by helping them to get rid of their physical forms altogether, sharing the exact same belief of the Yanome Tribe that "death brings true freedom" which is why it had chosen to become one with Hayase and thus her descendants/reincarnations through the decades and centuries.

Description
Nokkers are creatures that were created by an unknown being for the purpose of hindering Fushi's progress in preserving the world. The Beholder also said that they have been designed to weaken Fushi by stealing the vessels (bodies) he has gathered.

A Nokker's main form resembles long, presumably sharp, vines. However, they adapt to their environment and take on various other forms - forms stolen from Fushi. When in the forest, the Nokkers took on the appearance of vines and leaves. At Rean's house and on Jananda Island, it took on the appearance of rocks.

Abilities

 * The Nokkers have the ability to steal Fushi's forms, along with his memories of that form. For example. when the Nokkers steal March's form from Fushi, he is completely unable to remember her. He isn't even aware that anything was stolen from him.
 * They adapt to their environment and are constantly studying and learning about the world around them. When Fushi first encounters the Nokkers in the forest, it is made up of vines and leaves. The next time he encounters one on the island of Jananda, it is made up of rock.
 * The Nokkers are able to control a person's body, whether they are dead or alive.
 * They can communicate/speak human speech through telepathy or even write, like the one that had merged with Hayase' s very being and has been carried to her own reincarnations/descendants, as it had with her only great-great-great-great grandson.

Means of Killing
There are means of killing the Nokkers. Doing so will return Fushi's Memories and forms to him. The main weakness is the destruction of their cores, and this can be done in various ways.


 * Fire & Heat: Seems to be a very nice way of killing them, as it burns the core.
 * Crushing in Hand: seen when Fushi took on the late March's form in their very first encounter.
 * Piercing: So long as the Nokker's core is unprotected, they are easily killed with a simple pierce.

Prevention

 * Nokker Prevention Cream: Developed by Yuki Aoki, it prevents Nokkers from invading the body.

There are microchips that handle Nokker control, but it is unknown how they work.

Hayase's Nokker
A name referring to a specific Nokker that has been with Hayase since she left Jananda Island. This Nokker first appeared to her on the boat Fushi left her on in the middle of the ocean. Somehow, this Nokker attached itself to Hayase's wounded arm and has been passed down to her great-great-great-great-great grandchildren ever since in order to ensure Hayase's twisted desire to have Fushi all to herself in her next eighteen lifetimes (reincarnations and direct female descendants).

This Nokker is clearly different from the average Nokkers, capable of understanding its host and appearing to have a mind of its own. Whether the ability to understand a host's body only applies to Hayase and her descendants is currently unknown. It is also unknown what exactly this Nokker's goal is. It had finally gained the ability to commune its objectives by using Kahaku to write.

Abilities

 * This particular Nokker can communicate with its host body, but act on its own when in danger. This can be seen when the Nokker attacking Tonari broke Hisame’s arm and finger to run away.
 * This Nokker's main purpose aside from destroying other Nokkers is to sense and track Fushi.
 * Kahaku can utilize this Nokkers otherworldly strength and power, giving him superhuman strength and elasticity in his right arm.
 * This Nokker writes to tell Fushi about it's fellows' objectives and tell its friends' (other Nokkers) locations.

Quotes

 * "Please don't kill me."
 * "To help everyone."
 * "The Black One who made you is imprisoning my friends."
 * "That is correct."
 * "Not true. We wish to help everyone. To release you from your heavy, painful, suffering flesh. If you go to the other side, all of that shall go away."
 * "We despise Fushi and the Black One for making the flesh eternal."
 * "No. That is not true."
 * "They might me."
 * "The head of the Church of Bennett."
 * "The Nokkers have lost, but Fushi is weakened, too."
 * "A message from the others: If you want them back, please come to our next game."

Nokkers in the Modern Era
Nokkers have evolved to become microscopic in size and seem to dwell inside the bodies of those who wish to die.

These dwelling Nokkers are categorized into three states:
 * Fully-Merged: Completely taken over the human body leaving the spirit to wander or move on to Paradise.
 * Half-Merged: The Nokker is awakened and takes over the person's consciousness at times, as well as their physical body by amplifying its host's natural abilities to superhuman levels; namely Hayase and her descendants/eighteen reincarnations.
 * Carrier: The Nokker is deep inside the body of Hayase and her many times-great grandchildren/reincarnations but is hibernating.
