Help needed! Cant remember title...

Dont know if im writing on write place,so i apologize in advance...
so here's the thing i cant remember title,its childhood memory,probably from 198-ies and its set in that samurai era

its goes like this "a girl comes into this world,solves a conflict between some army that terrorized peasants,and after its finished,at the end,huge white collosuss rise up from earth crumbles above her. A sword of it or some part fells near her,launches her into sky back to her home"

very sad scene

Anyone?

uuuummmmmmmmm i think u are talking about escaflowne but idk if it is but it sounds like it
