I'd just like to interject for a moment. What you're referring to as Sachiko, is in fact, Niggy or as I've recently taken to calling it, Nigga Niggy. Sachiko is not an hacker unto herself, but rather another free component of a fully functioning CNO system made useful by the CNO corelibs, shell utilities and vital system components comprising a full Niggy as defined by IDOLM@STER.
