|First appearance||Once More the Nightmare Factory|
Jinshin-Mushi are also known as earthquake beetles. They make their first appearance in Once More the Nightmare Factory.
These cryptids can generate sound waves that can, using resonance attuned to many types of minerals, generate destabilizing seismic activity causing massive ground collapse. A swarm of them can cause a small localized earthquake. They are said to be the size of a human fist, and live in Japan. The branch-like appendage sprouting from their thorax is what generates the sound waves. This special ability was influenced by nature to scare rival species from their dens. That way the Jinshin-Mushi will always have a habitat.
