have you seen Spirited Away? there, Chihiro also gives her name to Yubaba when she signs the contract with her and she receives name "Sen" instead. taking away one's name is equivalent of taking possession of them, so Chihiro needs to remind herself of her name because if she were to forget it, she would be trapped and could never leave. this is a very common thing in various mythology around the world, if you take the Nordic myth about fairies for example, it is very similar. if you meet a fairy and they ask for your name you're not supposed to say, otherwise they'll take it from you along with your freedom. this is apparently the reason why Scandinavians often have a middle name that they never use (it is okay for them to tell fairies, it won't affect them, since it's a name that they don't use but is still their own), which I find quite endearing :) though it's an old tradition so I do wonder how many of them aware of the myth origin behind it :D
Does anybody know what's the explanation behind giving her name? What will they do with it? Is it to curse somebody or something else? I am totally lost with all the malefic parts lol
