Halfling

Halflings (小人族) also known as Hobbits (ホビット) are a race of Demi-Humans that seem to have historically co-existed with Humans. Many swore their allegiance to Rimuru Tempest and became part of Tempest after he slew the Orc Lord. In Tempest they were largely assigned to doing agricultural work out in the fields, with them able to be seen frequently in the background of the manga.

Appearance
Halflings look largely the same as normal humans, with the notable difference being their extremely short stature and notably large ears.
