Superb Song of the Valkyries: Symphogear - Season 5 Episode 7 Cutting the Tangled Thread

After Millaarc attempts to use mind control to have Elfnein activate the Chateau, the bracelet goes out of control and spawns Shem-Ha, who proves too powerful for Hibiki to defeat. Retreating to base, the gang learn that the waveform used by the creature is similar to a song Maria used to sing. Back at the Chateau, Elfnein's plea for help causes the Autoscorers, whose spare bodies were chained to the reactor, to reactivate and come to her aid. As the Autoscorers are all defeated trying to hold off Noble Red until reinforcements arrive, Elfnein manages to call upon Carol's powers to defend herself.
