Dune are large earthworm-like monsters capable of turning and maintaining soil for farm work. They are quite docile so even wild Dunes seem to spend their lives peacefully underground. Domestic Dunes will fight if ordered, but they aren't very strong. It is very rare for one to get into a fight. Dunes are Herbivores, that only eat dirt. It’s only fault is its speed. It can’t go very fast, or far. Visiting the neighboring towns seems to be its limit. Dunes have their own personality, their appearance may be of a huge earthworm but they're quite amiable and love to play. First seen in 『Chapter 139』 of the web novel.
