Goto, besides some of the other girls in H!P, know how important her fans are and she constantly makes sure we're happy because she knows that what we fans want is to know more about her, her 'real side'. She's a very down-to-Earth girl also, so she'll be glad to post silly pictures, or ones without any make-up.
She's a private person, so she knows her limits really well by not saying anything too personal, that should be obvious already, she reveals just enough for her and fans to have a casual relationship.
