I 愛 the story/movie spirited away. But umm... あなた know how when Chihiro was little and she fell into the river, i know that haku saved her, but did he save her in dragon form または did he save her like with the water? Help me please=)
I dont think that he saved her in dragon form, または else Chihiro would for sure remember that. I think he used his river spirit powers または something to save her. Maybe to calm the water down? または taking her back to 海岸, ショア through a wave. And I agree with Okami_Amaterasu on the whole how to become a river spirit :)
Okay I think I can help あなた out. If あなた remember when flying with Haku in the sky Chihiro 発言しました when she dropped her shoe in the river and fell in the water carried her back to shore. If あなた have the movie on hand または if あなた find it online she says that when they are flying in the air after leaving Zeniba's.
