Dr. Ver arms Miku with a Symphogear, both in order to raise Frontier and defeat the wielders.  His use of LiNKER means that any serious shocks could kill her.  Hibiki tries to stop her, but she only has two minutes and forty seconds before the overload from her Gear kills her as well.

Ela já perdeu a utilidade,
