Cutie Honey Universe - Season 1 Episode 6 May Fortune Befall You

One summer's day, a Panther Claw army led by Dragon Panther and Snake Panther launches a sudden airborne assault against Saint Chapel, as a part of Sister Jill's plan to drive Honey into despair and thus into her hands. With the school destroyed and their schoolmates slaughtered, Honey and Natsuko seek refuge in the woods, with their pursuers hot on their heels. Honey disguises Natsuko as a rock before taking the fight to Sister Jill herself, but ends up severly beaten. Natsuko bursts her camouflage and creates a diversion, allowing Honey to recover, and Naoko sacrifices her life covering Honey and Natsuko's escape from the island. Sister Jill slays Snake Panther for disobeying her orders to capture Honey alive; and for the death of her friends, Honey swears bitter revenge on Panther Claw.
