Ex Machina: Minerva

Ex Machina: Minerva (・ミネルヴァ) was an automaton with the Idea Engine equipped. Her power source was a miniaturized reactive furnace (反応炉) created by gathering and combining the energy in all the reactive weapons in the world Kokonoe Mercury could find.

Using notes left by Konoe Ayatsuki Mercury and Relius Clover on Machine God: Nirvana, Kokonoe built Minerva for Celica Ayatsuki Mercury. It both protects her and acts as an amplifier for her powers.

Minerva self-destructed to destroy Corpse Burial: Requiem, as it should have exploded as soon as the time-stop ends, destroying the whole world.
