She's a mega star, so she writes big :P :D
And why would she write her name in Chinese characters?
If you have seen her signature, then you would know that it's spelled with 'AYU' and stuff and such :P :D

I saw it yesterday and looked at it for a good while before determining myself that it was fake.. so sad.. as I would love to have Ayu sign something.. but I'd much rather see her in concert, AND have her sign something.. I still am in love with the little pink ball up there..

the guy is selling so many fake signatures! even Gackt.. I must admit that is a very lovely picture of gackt.. but the signature is deffinatly fake there too.. Again.. very sad :(
