Juno

Juno (ジュノー, Junō), is the goddess and Emperor of Tophet, an organization of unknown goals that is, in actuality, a subterranean nation that secludes itself from the outside world of Gamindustri.

She aspires to take over Gamindustri and bring on what she calls the "Gamindustri Golden Age".

Etymology
Juno is the name of the queen of gods from Roman mythology. It correlates with her position in the series as the textbook definition of a goddess rather than a CPU and her claims of being the strongest goddess.
