Will Haku meet Chihiro again..? Well Chihiro doesn't remember anything about her days in the spirit world...

its not known, Haku tells her not to luck back and she goes its not known what he did...
I think they might meet again since Haku did promise that to her

Yes, I think if they will make a sequel of it.
I've always wanted to see it's sequel it
Always bother me everytime

I always believed that Haku and Chihiro would meet again. And even if Chihiro forgot, memories can be hard to recall but never forgotten (Zeniba). So she would remember eventually. And Haku would do anything to meet Chihiro again, because he loves her.
