Ok i watched ALL the episodes again...and again ive learnt stuff that answers some questions and makes me want to ask more. first of alli remeber asking if everyone as in sasuke, sakura, neji, shikamaru and all those ppl know abt the kyuubi inside naruto. some ppl actually said yes they probably know by now. well its wrong they dont and they show it in more than one episode. first of all in the fight between Naruto and Gaara, wen the big frog tranformed into the kyuubi to fight gaara's demon, sasuke saw it and he said a fox? and he had no idea what it was and y it showed up there...second thing is wen itachi went to get naruto, kisame said "and to think that this little kid has the kyuubi in him" and then naruto gets shocked and goes like "they know abt kyuubi!!" another thing which means theyre not supposed to know. plus the fact they always wonder where the red Chakra comes from. anyway moving on one of the topics that got me curious..and this can probably be answered by manga readers....in the episode wen Gekkou Hayate died...this Anbu girl comes and she says she will take revenge for him and she went to his grave twice. so i want to ask who is she? and what does she have to to do with hayate..were they friends? did they work together? and also what does she have to do with kakashi? for some reason i thought she was rin the first time but i saw the picture in kakashi's room with obito and rin and yondaime and she has light brown hair. i have no idea if rin is alive or dead but i thought it was her... another thing what does Senpai mean..i thought u say it to ur parents or granparents but she said kakashi-senpai and im sure he isnt a grandfather or smthg lol

Senpai is another name for a senior person, dude have you ever seen Rising Sun with Wesley Snipes and Sean Connery (sp). Also we don't yet know anything about the ANBU girl except that she must be nice to be on the ANBU team. You are correct not to many people know about the Nine tails, all the kids parents know because they were there when he was destroying the village, but the 3rd forbid anyone from talking about it, so there kids were never told about it.

Yep, and another thing I learned is that "senpai" can also be used to call a "respected upper classman". So from that we can discern that she's younger than Kakashi. And even us manga readers still don't know more about this ANBU girl.

For all your other questions, what kidistight said is true: while many Konoha adults know about the Kyuubi inside Naruto, most of his generation doesnt know since the 3rd forbade anyone who knew about it to talk about it (Kyuubi inside Naruto).
