We first meet her as the gentle and calm manager of Sheryl Nome... later revealed as a cyborg as she activates a weapon called a ""Dimension Eater". She's destroyed in the ensuing fold dislocation while calmly wishing everyone luck as the as the fold dislocation eats up half of the planet Galia IV and triggers a Vajra attack...
Grace uploaded her mind into another cyborg body.
She was the one who started all the attacks, all the suffering so that she could link to the Vajra fold communication network and "evolve."
Her ultimate plan was to kill all the humans who would not submit to her and have fold crystals embeddded in the others so they could be completely under her control, since nothing in the N.U.N.S. arsenal would have been able to withstand the might of the Vajra's interdimensional abilities in a galactic scale conquest.
