The Ex Machina: Minerva (自動人形・ミネルヴァ Ekusu Makina: Mineruva, JP Automatic Doll: Minerva, LA From Machine: Minerva) was an automaton with the Idea Engine equipped. It was an Embryo Storage number 3.
Using notes left by Konoe Ayatsuki Mercury and Relius Clover on Machine God: Nirvana, Kokonoe Mercury built Minerva for Celica Ayatsuki Mercury. It both protects her and acts as an amplifier for her powers.
Her power source was a miniaturized reactive furnace (反応炉 hannō ro) created by gathering and combining the energy in all the reactive weapons in the world Kokonoe could find.
Minerva self-destructed to destroy Corpse Burial: Requiem, as it should have exploded as soon as the time-stop ends, destroying the whole world.
