A member of Babel, she is a girl known as an “Artificial Apostle” and uses equipment similar to that of an emissary. She has the power of an emissary, but doesn't seem to have much confidence in it.
The core she uses is the “Heart of Pandora,” a device that provides energy to Beta's artificial emissary equipment, but the Tower of Babel has not yet been able to figure out how it works. However, as long as it's operating normally, it seems that the energy source is no longer important.
