Senhime Zesshou Symphogear - 1x11 - 月を穿つ- Followmy.tv

As Ogawa tries to get Miku to safety to the 2nd Division headquarters, they are attacked by Finé, who is revealed to be Ryoko as Genjuro arrives on the scene to fight against her. However, Ryoko manages to critically wound Genjuro and goes on to take the Durandal. As Ryoko goes on to confront Hibiki, Tsubasa and Kurisu as they arrive on the scene, she explains how she is an ancient priestess who possessed Ryoko's body 12 years ago. She then proceeds to bring out the Kadingir, a huge cannon that she had been building in the 2nd Division's elevator shaft all this time, which she plans to use to destroy the moon which possesses some spell holding back her true power. As the cannon prepares to fire, Kurisu sings her swan song and sacrifices herself to stop the beam from completely destroying the moon, to the shock of Hibiki.
