After being seriously injured by the Nephilim, Hibiki is unable to control her Symphogear.  She flies into a rage, destroying the Nephilim and ripping out its heart.  During the post-fight medical exam, it's discovered that if she continues to use her gear, she'll die.
The heartbeat of awakening!
إنها نبضة قلب اليقَظة
Der Herzschlag des Erwachens!
¿El latido del despertar?
¿El latido del despertar?
Il s’active !
Il battito della rinascita!
A batida do coração do despertar!
