Starlights, Kakyuu and Chibichibi Cast List
There have been several musicals with the Sailor Starlights around, and while some of the cast started out earlier with the musicals playing other roles, the Starlights are often what they are remembered best for. Princess Kakyuu herself didn't appear in many musicals, however.
It was also less likely to see Chibichibi in the musicals as well. Still, because she was a younger actress she was often double-cast and therefore had plenty of actresses playing her!
