Eina

One of the many maids working in Klein Sandman's castle, Ena treats all members of Earthgertz and the other maids well. Easily frightened, Ena finds simple arguments harsh and battles against the Zeravire to be unbearable, but does her best in her piloting duties as the second driver of the G-Driller. She has cared and looked after Toga Tenkuji since his arrival into Klein Sandman's Saint-Germain Castle. In Gravion Zwei, she pilots the Geo Javelin alongside Luna Gusuku.

In Gravion Zwei, Ena reveals herself as one of Sandman's Proto Gran Divas. It took Sandman nearly 50 years to create her current, artificial body. After she is destroyed following a Zeravire attack, her memories are immediately transferred to her original body, located inside the Sol Σ Gravion, stored on the moon.
