Slayers - Season 1 Episode 10

Lina and the others challenge the Dark Lord, Shabranigdo. Unfortunately, he is too powerful and no magic works against him. Gourry is knocked down and Zelgadis is struck hard. Then, Lina is given the Sword of Light and it increases the power of her sorcery. Lina challenges Shabranigdo with the most powerful incantation, Giga Slave, which is superior to the Dragu Slave. She realizes that Rezo is still inside Shabranigdo. In the final moment, Rezo gets away from the body of Shabranigdo and finally Lina's Giga Slave smashes the Dark Lord. Upon arriving in Atlas City, Zelgadis decides to part ways with Lina and Gourry.
