Slayers Excellent (スレイヤーズえくせれんと) is the second set of three Slayers OVA episodes featuring Lina Inverse and Naga the Serpent, following the earlier OVA series Slayers Special. The series was written by Keiko Watanabe basing on the original stories in the light novels by Hajime Kanzaka, directed by Hiroshi Watanabe, and originally released in Japan in 1998–1999.
In the first episode, "Labyrinth" (らびりんす Rabirinsu), Lina and Naga first meet and are forced to battle zombies, ghosts, a vampire, and Naga's own tomfoolery. In the second episode, "A Frightening Future" (恐るべき未来 Osorubeki mirai), Lina is hired to escort a bratty and spoiled daughter of an aristocratic family in a job that will turn out much more challenging than she excepted. In the third episode, "Lina-chan's Lovely Makeover Operation" (リナちゃん・おしゃれ大作戦 Rina-chan oshare dai-sakusen), Lina and Naga take opposite sides in an out-of-control dispute between conservative and risque fashion designers.
Plot
"Labyrinth"
The episode begins with a retrospective story of Lina Inverse's and Naga the Serpent's original meeting when Naga began her obsession with Lina as her self-proclaimed arch rival. In the present, the two are traveling together when they are directed by residents of a village to the mysterious ruins nearby. After arriving there, however, they are ambushed by zombies and soon realize that this was all just a trap by the villagers as a sacrifice to a vampire dwelling inside an ancient labyrinth.
