I am going to against all I have been rooting for up until now and go out on a limb here. Chances are I will have to recall this post later since it will get rolled over by so many "0MmGz Zoro!!!!!" posts and Thank-you posts.
I have to admit that I don't like it either, but two things come to mind:
[1] We know that Luffy is pretty tired out, and hasn't really taken the "I really have to fight this guy seriously" stance yet. So let's not give in just yet. (For Luffy, that is).
[2] This is the part I don't even want to say, but: ^^ Referring to your quote, maybe Oda really is trying to tell us something with the whole Haki jargan. We have another Logia pop up on the grid, another fighter capable of hurting Luffy without a DF / issue with Luffy's DF, and we have Rayleigh who can seemingly fight Logia's with something and can also use Haki ~~ and does so quite freely.
Maybe, and I do not want to think this way myself, but maybe Haki/Spirit will have something to do with Luffy's advancement in technique etc. Whether or not it is the means to fighting a Logia, who can say? Whether or not it is how Sentoumaru is attacking Luffy or not, we will have to find out. I am just tossing it out there for additional thought.
I'm not a fan of this 'haki' idea either, and like I had hypothesized with some other members that it may be some form of attack similar to zoro's manifestations. But we just have no idea :p
Regarding Luffy, I don't care how tired Luffy was supposed to be. For starters, the SHs shouldn't have been that winded fighting the PX-4, and Oda is pulling the same card he did in W7. Luffy couldn't fight Blueno because he was distracted by Robin leaving, and now Luffy can't fight Sentoumaru b/c he's distracted by Zoro. And don't get me wrong, I don't mind characters being stronger than Luffy, but I feel like Sentoumaru is too much stronger than Luffy.
@Urian:
But this is not the main subject, the main subject is "Sentoumaru" damaging Luffy internally and how the bodyguard is using normal moves and saying "I am not using any special technique or devil fruit" and I am sure that he is saying the truth and Luffy is the one who is suffering internal damage because the use of the Gears and this is why he is bleeding and exhausted before time, Luffy has got heart problem with the abuse of the Gears, we are not talking here about Sentoumaru being able to hit internally Luffy, we are talking here that Luffy needs to see a doctor.
The other part of the equation is Zoro, people says that he is out off the scene only because he is sustaining more injuries than the rest when the truth is that Kuma transferred Luffy pain and fatigue to Zoro and not his internal damage. Luffy was full of energy because the pain and fatigue in his body was in Zoro but the internal damage continued to be in Luffy.
I really don't know if I buy this Luffy is suffering internal damage from using gear second. this was lucci's hypothesis about the side-effects of luffy's technique. lucci's doesn't have luffy's rubber body and can only guess at how much (if any) luffy's body is damaged by him using gear second. so i really don't think this is the reason for luffy's fatigue. i'd put my money on sentoumaru dealing the damage.
@Garp:
Good lord, you're clearly not paying attention. Rayliegh can hurt Kizaru for some reason but his hits have to land. Apoo can't hurt Kizaru so it doesn't matter if his hits land or not. The only one of Rayliegh's hits that landed occured when Kizaru was trying to go after Zoro/Luffy as opposed to fighting Rayliegh hence him not being focused.
the point isn't being caught off-guard, b/c we've seen Apoo catch Kizaru off-guard before. the point is the rayleigh is capable of making kizaru bleed even though kizaru is a logia user, and we've seen no use of DF from rayleigh so far. this is the importance of the scene with the bloody cheek.
