テトラ

A combat golem created by Eleanore. Eleanore considers Tetra to be her masterpiece, as she is packed with extreme destructive potential and is completely loyal.

She is extremely dependent on Eleanore, detests making decisions by herself, and often sticks very close to Eleanore. As she was made using the parts of destroyed golems in the previous war, these parts only show their true power during combat. During daily life, however, she often trips as a result of the parts being unbalanced.

She takes care of Eleanore's personal needs in day-to-day life, and apparently Eleanore really likes the coffee Tetra makes.
