When I was searching for FSN I found, about year ago, that there are Fate\Zero light novel about the past when Kiritsugu was master of Saber, in short previous Holly Grail War... There is also Fate\hollow ataraxia. Fate/hollow Ataraxia is something like a sequel to Fate/stay night. Servants are living as normal people and I'm not sure about the story either. Saber, Rin, Rider and 2 new girls are living with Emiya in the same house and town, and they are his maids *note: not sure*. Lancer is florist and Caster is with her master, I mean like they are together... Fate\stay night is hentai game. From Fate\stay night game the company TYPE-MOON made anime taht we are in love with... The ero-ero parts are when Archer died fighting with Berserker, in order to protect Saber, Rin and Shiro... It happend in deserted house, the part when Shiro was filling her with his magical energy. You'll notice. Second ero-ero scene is when they were fighting Gilgamesh and they almost died *note: when Shiro created Avalon*. Saber's magical energy was empty and Shiro filled her... Those scenes were excluded (thank GOD- jap. kami-sama). The ero-ero scenes in the game are great and thank god they didn't spoiled anime. If u can't imagine how Shiro gave her magical energy leave a comment at my profile and i will answer you... That's all for now. Contact me if you have any more information about Fate\Zero and Fate\hollow ataraxia...
