A Guardian Spirit Beast ((しゅ)()(れい)(じゅう)()()()()()(), Shugo Reijū) is a parasitic-type Nen beast possessed by the king and princes of the Kakin Empire.[1] Since Guardian Spirit Beasts are visible to Nen users without the aid of Gyo,[2] but invisible to everyone else,[3] they could be created with Emission.


Seed Urn

The Seed Urn

In the age of rival warlords, Kakin was a small country threatened to be absorbed by its neighboring countries. Around that time, according to ancient manuscripts, the first king of Kakin conjured the Seed Urn inspired by "Worm Toxin"[1] 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.[4]

The Seed Urn

The Seed Urn, a conjured pot with some facial features, is the pivotal item for the beginning of the Succession War.[1]

The Seed Urn Ceremony

The Seed Urn Ceremony (()(ちゅう)(らん)()()()()()()(), Kochūran no Gi) 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 its mouth-like opening. At this point, a purple smoke fumes from the urn with a tiny female sprite dressed in Kakin traditional clothing holding a small egg, which she inserts into the host's mouth. The princes will thus be granted a Guardian Spirit Beast when the egg hatches.[1]

The sprite is invisible to ordinary people,[1] since it is made out of Nen, which caused Queen Oito to originally believe that the ceremony was only a purposeless tradition of the Royal Family.[2]

After receiving the egg, trying to escape the Succession War will result in the fugitive's death by countless ghostly hands that appear around the person (enforcing the ceremony's conditions).[5]


Born from the deceased king's strong desire of perpetuation for his descendants, a Guardian Spirit Beast is a parasitic-type Nen beast that possesses a person related to the deceased, feeding on their aura as an energy source and taking a shape and an ability which are influenced by its host's character and disposition. The more unsavory the prince's characters are, the more disgusting, obscene and threatening-looking their beast is. Since the Nen beast is not a direct creation of its host, it cannot be controlled at will.[1]

All Guardian Spirit Beasts are imbued with two primary instinctual rules:

  1. they do not fight and kill one another;
  2. they do not attack another human whom a Guardian Spirit Beast is protecting.[4]

Even without their special abilities, Guardian Spirit Beasts can protect the host against threats, including bullets[6] and other Nen abilities,[7] even if the host attempts to kill themselves, thus preventing their suicide.[6] However, there is no guarantee that the protection of the host is a Nen beast's highest priority,[8] and some can leave their presence.[2] It is also aware of any Nen users that are able to see it and, if not actively attacking, it simply stares back at them,[9] and some even intimidate them.[4]

Each Guardian Spirit Beast is endowed with its own Nen type, which can differ from its host's. Its abilities, however, are still influenced by the host's personality and possibly also their Nen category.[10] The beasts can also react to their respective host's emotion, as Camilla's and Marayam's changed their appearance in accordance with the former's outrage[11] and the latter's anxiety.[12][13] Some of them can even avoid showing themselves[14] or lack a form in the first place.[5]

The host cannot see their own Guardian Spirit Beast, nor are they able to see those of other hosts from the same generation even if they are a Nen user. Balsamilco surmised that there must be a Limitation that prevents the ceremony participants from seeing the Nen beasts, or a condition that must be fulfilled before they can do so.[11] However, a host from a previous generation can see the Guardian Spirit Beasts of the next.[15]

According to Kurapika, the invisibility to most of the Nen beasts makes them a low-risk ability, which the hosts compensate for with a large aura expenditure as well as the complex system of Vows and Limitations in place. This led him to speculate that if a prince managed to pull out of the Succession War, all Guardian Spirit Beasts would disappear.[3] A Guardian Spirit Beast cannot manifest itself while the host is in a state of Zetsu,[16] and it may find itself unable to protect its host if the latter has run out of aura.[17]

  • "Worm Toxin" (蠱毒, Kodoku) is a type of Japanese poisonous magic, derivative of the Chinese Gu (蠱*, * or ku*) magic. To create it, several poisonous insects are closed together inside a jar, which is opened when only one of them remains. The surviving insect is said to have absorbed the poison of all the other insects.
    • The inspiration for the Seed Urn is self-evident as the similarities do not stop at the ritual through which the members of the Kakin Empire's Royal Family obtain a Guardian Spirit Beast, but extend 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.

Intertextuality and References

  • The Seed Urn's facial features highly resembles the facial features of the clay dolls from the late Jōmon period of Japan.
  • In Togashi's manga YuYu Hakusho, an egg is given to new Spirit Detectives. After a while, a Spirit Beast will hatch from it, with its appearance, personality and powers resembling those of the one who keeps it. The whole process is very similar to the Seed Urn Ceremony through which Nasubi and his children obtained their Nen beasts.
  • 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.
