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.
I'm really glad, though.
مع أنني مسرورة بذلك
Das freut mich sehr.
Pero me alegra.
Pero me alegro.
Oui, je suis vraiment soulagée.
Però ne sono davvero contenta.
Mas fico feliz, de verdade.
