NoImage Alert.png Judging from the current state of this page, there is no available image on the Overlord Fandom as of yet to help emphasize its appearance. Since it is lacking visuals, this article requires an image for the first time, the kind which should be high quality and distinguishable. Unknown Intruder, you could go out of your way to assist the Overlord Wiki by adding an image that came from any Overlord adaptation to it. It cannot be a fan-art or fan-made. You must upload the official ones visually drawn by the main producers of the light novel, manga and anime adaptations.

Gashokukochuuou (餓食狐蟲王) is the Area Guardian of the Large Hole in Nazarick. He is also one of the Five Worst, the top five most disgusting NCPs of the tomb, holding the title "Worst Appearance."


Gashokukochuuou appears to be a parasitic creature, likely an insectoid. Also, its epithet, "Worst Appearance," implies he has a hideous appearance, even amongst some Nazarick's ugliest NPCs.


Little is known about Gashokukochuuou's personality. However, he appears to hold no sympathy for humans and is fine with using humans as his "house."


Gashokukochuuou holds the title as "Worst Appearance."[1]


The Invaders of the Large Tomb Arc

Ainz orders Aura to bring Hekkeran and Imina to the Large Hole, saying that Gashokukochuuou is running out of "nests" to use. However, Aura managed to convince her master to give the task to her brother Mare instead.[2]

To celebrate the acquisition of its new home, Gashokukochuuou held a house-warming party, inviting the rest of the Five Worst to its home on the 6th Floor.[3]

Abilities and Powers



Gashokukochuuou is on good terms with Cocytus.


  • It is very likely that Gashokukochuuou is a parasite-type NPC.
    1. Its name "餓食狐蟲" sounds similar to "芽殖孤虫," a Japanese name for Sparganum.
    2. It uses humans as a "house."
    3. The author said that Hekkeran and Imina gained weight after volume 7, it seems that the Gashokukochuuou or its family are infesting them.
    4. Aura hates to visit the Large Hole and sends Mare instead. This reaction is very similar to that when she heard about Kyouhukou.
  • In the official English version of the light novels, he is referred to as the "King of Hungry Prolyferum."
