<p>As usual, Oda Eiichiro has a "creative" explanation for that too! Oda blatantly disobeys the Laws of our world in One Piece.</p>

<p>In SBS Volume 44, when asked how Sanji could beat Jabra by heating his leg, without burning it, Oda's response was:</p>

<blockquote>
  <p>Sanji's leg is not hot!! His heart was burning so much hotter!!</p>
</blockquote>

<p>If asked your question, he would <em>probably</em> say something like:</p>

<blockquote>
  <p>Learning Haki, spending 2 years chased by Okamas, and being separated from ladies, especially Nami-san and Robin-chan, has made his heart burn much hotter!!! Even water cannot extinguish his burning heart!!!</p>
</blockquote>

<p>I know, it doesn't feel satisfying, but this is how Oda-sensei's "explanations" usually are!</p>

It's no use trying to think of the OP world in terms of our world. Remember Pappagu, who learned to talk because he *thought* he was a human, and it was too late, when he realised he was not! Even *Luffy* questioned how that could work!

Also, we could just blame it on the Haki. :P Luffy's haki makes his body becomes *black*. We've seen Vergo turn purplish when he uses haki. So may be, Sanji's burning heart and his haki, takes this form.

@R.J As for Luffy's Haki, there's a more "acceptable" reason for the black color. Read my answer here: http://anime.stackexchange.com/a/5717/99. I don't agree with the accepted answer there.

Totally agree with you Happy. Just that, I'm saying that it might be a case, where Sanji's leg turns that color when he uses Haki. It's just a speculation, based on the other Haki colors! :)

Yes, that is totally possible. Oda's imagination knows no bounds, no telling what he might be thinking. :)

Oda's imagination has no bounds, because the information available on this planet has no bounds. He is known to pick up so many things, from names to personalities, from so many various sources, that many things in One Piece world are mere speculations(unless he reveals them).

Im kind of getting what your trying to say. But the haki which is shown is normally for defence, perception and conquerers. So this cannot possibly be haki in the form of fire!
The heat in his heart could heat up sanji, but using that heat he burns his opponent, that is weird O_o

<p>As you know, Sanji has a move called Diable Jamble, where he somehow manages to generate fire on his leg by rotating with great speed.</p>

<p>We have seen this move first when he was fighting CP9.</p>

<p>According to science, fire can be generated by friction, but it should be spontaneous. This explains as to how he was able to generate while he was fighting CP9 at Enies Lobby.</p>

<p>But after the timeskip, when the Straw Hat Pirates were on their way to Fishman Island, they encountered a Kraken. How did Sanji generate fire in water?</p>

<p>In water, there is no rough material via which, fire can be generated.</p>

<p>And even if it is somehow achieved, how can the fire not get extinguished by the water!?</p>

As we all know, Sanji has acquired Haki and Sky Walk. If Sky Walk (also Blue Walk, but underwater) can serve as a foundation for friction, and Haki as an incinerator, then we get fire underwater. We know that Luffy can generate fire thanks to this logic... Haki and speed.
