S1·E21 UPSET! Gourry vs. Zangulus!

Lina, Gourry, Amelia and Sylphiel get to Rezo's museum. They break the seal by the Sword of Light and look for Rezo's secret in the underground chamber. They are caught in a trap set by Eris and become separated. While Lina searches for Gourry and Amelia, Sylphiel asks her about her relationship with Gourry. She tries not to show any feelings for Gourry other than a mere friendship. In the meantime, Gourry is in the middle of man-to-man battle with Zangulus. He is cornered by the strong opponent but Gourry uses the full force of his Sword of Light and defeats Zangulus.
