Sailor Moon Sailor Stars (1996)

Sailor Moon Sailor Stars is split into two arcs; the first arc deals with an enemy they thought was dead: Nehelenia, who comes back with one intention - to destroy everything that Sailor Moon loves. After they defeat Nehelenia, a new threat comes from beyond the solar system, along with a new senshi, the Sailor Starlights. But determining whether they are friend or foe is harder than it looks. And on top of that, Mamoru has gone overseas to study and Seiya of the idol group the Three Lights is interested in Usagi.
