Gobu-É, also known as E or Earthe, is a female goblin from the same tribe as Rou. Initially assigned to the tribe's mining team, her responsibilities focused on resource extraction and subterranean exploration. She becomes mates with Gobkichi (Kichi). This relationship encounters physical challenges after Kichi evolves into a Minotaur, creating a significant size difference that makes intimacy hazardous for her.

The physical incompatibility persists until E herself evolves, transforming into an Earth Lord. This evolution alters her form to match Kichi's scale and resilience. The change resolves their physical limitations and connects intrinsically to her foundational earth-based mining role. Her progression demonstrates adaptation within the tribe's social structure regarding interspecies relationships navigating evolutionary changes.

E's narrative remains closely tied to Kichi's, without detailed solo story arcs or independent developments. Her background is defined by her mining role and relationship dynamics.
