Hey, I've just finished reading up to
Chapter 153 of the manga. Just to let you know if you are here and haven't read past what has been released here in the US or have only been watching the anime, then
PLEASE LEAVE! Unless you are willing and ready to be spoiled then get out of here cause this ain't the place to be. I will not be using any spoiler tags.
Ok, for those who are gonna continue on, yeah I've read from the events in episode 57 to about Chapter 153 in the manga. Since there is hella lot of talking in this book, I have to rely on my limited knowledge of Japanese to guide me through, but I still have lots o' questions and comments.
1. In the Hyuuga vs. Naruto fight, what is up with the Nazi or Native American type symbol on his head? I know that it has to do something with his side of the clan, but then it looks like his dad or whoever it was died. Was it Hinata's father's fault? It seems like Hinata's father apologized to him later after the fight though.... It also looked like that symbol gave the dude that was with Hyuuga mad pain or something....
Answer: That seal is used my the Main Family to "control" the Branch Families, the seal is used to kill at any time any member from a Branch Family. Hiashi(Neji's father) was killed by this. If I remember well he sacrificed himself instead of Neji's father when some ninjas from other country did something to blackmail them(I think they kidnapped someone I don't remember well, probably Hinata). So, the prblem was that if Hizashi(Hinata's dad) was offered as a prisioner, the secrets of the Byakugan would be revealed cause he is from the main family. But if it was someone from a Branch Family, by the time you die, the seal in the forehead acts as a remover of the Byakugan.
NOTE: Some things like the names of Neji or Hinata's father may be wrong. But the things about the seal is true.
2. When Hinata got into coughing fit in the middle of the Hyuuga/Naruto fight, Kabuto offered to help in his missing-nin hunter outfit which was kinda freaky IMHO. Anyways, it seems like he knocked her out for no particularly good reason. Was that just to get her and Kiba before the bigger attack? Or did they do it to kidnap her or something to use against Naruto later? What happened to her and Kiba afterwards?
Answer: I really don't find it important if they were knocked out. But they get up as soon as the attack to Konohana starts.
3. I can't believe episode 55 was actually in the manga.... Poor Rock Lee. Isn't he like the tragic hero or something?
Answer: Rock Lee is the MAN! Like Naruto said
Ohhh Rock Lee!
The way a man should be!
4. When did Shikamaru and Naruto get so friendly? I mean him waiting there in the room was nice and all, but like...considering all that happened before it was a bit of a surprise. But then again it shouldn't, it's not like he's Ino or god-awful Sakura.
Answer: They probably know each other since small kids.
5.Gaara went to go pay a friendly visit to Sasuke and Kakashi. Was it just like to say hello or to spy on their progress?
Answer: Probably to give them kisses and hughs. No I'm kidding, maybe he was just desperate to start the fight since Sasuke was late for the match.
6. Does it explain why Gaara is the mother of sand and mascara? Like does he have some youkai-ness hidden within him or he is just one hella powerful human?
Answer: He has a demon sealed in his body. It is actually some evil priest with great power. BTW, he kicks ass!
7. I forget what Orochimaru's plans are exactly? Is it to take over the world?
Answer: Take over Sasuke's body because of his Sharingan and eliminate Konohana.
8. Is that female Orochimaru a personal female impersonator or like his sister? You never see her in the flashbacks yet she's so darn powerful.
Answer: Who??
9. The 4th Hokage looks strinkingly similar to Naruto. Now, this book is a great example of beautiful and distinct character designs. I can't just imagine that this striking similarity is it just coincidence or just a monkeywrench that the author put into the mix. Any clues on that one?
Answer: They may be relatives or maybe not. (Hey this is another anime)
10. When Gaara turned into that monster was that just sand? Also, I thought that the fight between Naruto and Gaara was very, very good. I was especially, feeling it in the end when Naruto looked like he was actually gonna get up and Gaara was all like "NOOOO!! No more! God you monster, why don't just ever stay down!!" Well he didn't say that, but I'm sure that was what was in his head.
Answer: That was part of Shukaku of the Desert. Wait for the badger form.... 
11. I feel good that Sasuke his seeing how much more powerful Naruto is becoming. For Sasuke to still think that he has a chance in a fight against this boy would just be too stupid, even for him.
Answer: We cant really tell until they fight.
12. I know that Sasuke's brother came back, but apparently he was there to either take Naruto away or kill him, didn't see the latter there, but there was some bad news going on though. Did it get reported back somewhere that Naruto _must_ die or something? Is Sasuke's brother even working for ole' Orochimaru? Which brings me to my next question....
Answer: Itachi is a badass mo*** fu****. He is stronger than MJ (Orochimaru). Itachi is working for some organization called Akatsuki that is formed by missing nins. the reasons he wants Naruto are unknown, probably the Kyubi.
13. Why did Ero Sennin take Naruto away? Was it like for Naruto's own good 'cause mad people are out to get him or to train him even more? And if the latter why at that particular time? Like, are they perparing Naruto for something he doesn't know about yet or we don't know about yet?
Answer: He is training Naruto to kick everyones ass!
14. Did Sasuke's brother give a reason to why he even slaughtered his entire clan? Was he just on some extreme power trip?
Answer: Ask for speculations.
15. I think that it's very cool that Ero Sennin is becomming somewhat of a father like figure to Naruto, even if not really, but it does give him a male to look up towards to drive him even further.
Answer: 
16. Before I forget, what was the significance of Ero Sennin bringing that chick upstairs in the hotel when he was fighting Sasuke's brother? I thought that Ero Sennin was gonna be like "Naruto, today I'm gonna turn you into a man." I don't know.
Answer: Naruto is not THAT pervert.
Sorry for all the questions. I know it's a lot, but the manga is really good and it would be better if I could get those points. ^_^ Also, if the answers lay beyond what I have read then please don't spoil me with the answer, like it has something to do with some major plot development...then I can just wait patiently....
