The Kazura squid can first be seen in the Great Fault, as embedded spiky eggs below 6750m. Once hatched, they live in the upper regions of the 4th layer, in the water housed atop the goblets.
It is unknown if they are edible or pose any harm to Delvers. Riko states that the squid has no name, but on a map of the 4th layer, the nesting grounds are labelled as 'Kazura squid nesting grounds' along the edges of the 4th layer.
- According to Riko, its species doesn't have an official name.
