Slayers Royal

Slayers Royal marks the first time Naga the Serpent — Lina Inverse's companion from the prequel stories — appears alongside the main cast of Gourry Gabriev, Amelia Wil Tesla Seyruun, and Zelgadis Greywords. Their path crosses with Lark, an elven boy under attack by mazoku demons. After rescuing him, the group learns that the demons have kidnapped Lark's sister to seize an ancient amulet now in his possession. The amulet carries a power far beyond any of them realized — wielded correctly, it can resurrect the demon king Ruby-Eye Shabranigdu and bring the world to ruin. Stopping that from happening means staying ahead of the mazoku, protecting the amulet, and trusting an unlikely alliance to hold together long enough to matter.
