Are you talking about Platinum, her purpose was pretty much fulfilled after destroying Terumi because he was the one along with Izanami to start the phenomenon of the story since Trinity saved him ._. Ragna's purpose is either breaking free of Izanami's control and protecting the Azure or becoming the black beast with Nu in the next game to ensure Izanami's plans to turn everyone into seither, which obviously won't happen, and Jin's purpose is to kill Ragna to prevent the black beast, its been said hundreds of times.
