Guardian Spirit Beast

Nen Beast (念獣, Nen-jū), also known as Guardian Spirit Beast (守護霊獣, Shugo reijū), is a conjured parasitic-type Nen creature possessed by the king and princes of the Kakin Empire.

History
In the age of rival warlords, Kakin was a small country threatened to be absorbed by its neighboring countries. Around that time, the First King of Kakin conjured the Seed Urn inspired by the "worm toxin" and had his children fight in a succession contest for the throne, which is the foundation for Kakin becoming the superpower that it is today.

The Seed Urn


The Seed Urn's facial features highly resembles the facial features of the clay dolls from the late Jōmon period of Japan.

The Seed Urn Ceremony
The Seed Urn Ceremony (壺中卵の儀, Kochuurannogi) is part of the Kakin Royal Family Tradition, to prove one's inheritance to the Urn, the host focuses their desire for the crown and offers a drop of their blood to the Urn, then puts their hand in the center of the Urn, a fairy-like creature will then come out from the top of the Urn holding an egg and inserts it into the host's mouth. They will then be granted a Nen beast.

Queen Oito once believed that the Ceremony was only an old tradition carried out by the Royal Family.

Properties
Born from a deceased person's strong desire of perpetuation for their descendants, a Nen Beast is a parasitic-type Nen creature that possesses a person related to the deceased, feeds on their aura as an energy source and takes a shape and an ability influenced by its host's potential and character, however since a Nen Beast is not a direct creation of its host, it cannot be manipulated at will. A Nen Beast will instinctually protect its host but there is no guarantee for it to be its highest priority. A Nen Beast is free to leave the presence of its respective host. It is also aware of any Nen users that are able to see it and simply stares back at them and in one case, Tserriednich's Nen Beast intimidates Theta.

The host cannot see his own Nen Beast or other people's Nen beasts even if he is a Nen user. Balsamilco surmised that there must be a limitation that prevents the Ceremony participants from seeing the Nen Beasts, or that there's a condition that must be fulfilled before they can see them.

A Nen Beast is imbued with instinctual rules that distinguish it from regular beasts and Nen beings, the known rules are:
 * 1) Nen Beasts do not fight and kill one another.
 * 2) Nen Beasts do not attack another human whom a Nen beast is protecting.

Trivia

 * Kodoku (蠱毒, worm toxin) is a type of Japanese poisonous magic, derivative of the Chinese Gu (traditional Chinese: 蠱; pinyin: gǔ; Wade–Giles: ku) magic. To create it, several poisonous insects are closed together inside a jar, which is opened when only one of them remains. The title thus has a symbolic function, as it refers not only to the ritual through which the members of the Kakin Empire Royal Family obtain a Nen beast, but also to the whole succession war: the siblings are in fact forced to stay on a ship journeying to the Dark Continent while they attempt to kill each other, with the only survivor becoming the legitimate heir to the throne.
 * When asked to place his hand in the mouth of the Seed Urn, Tserriednich worried it might be bitten off: this may be a reference to "La Bocca della Verità" ("The Mouth of Truth"). Starting from the Middle Ages, it was believed that if one told a lie while his hand was in the mouth of the sculpture, it would be bitten off.
