i didnt notice it, thanks for pointing it out! it's really a sweet thing to do from both mangakas, im so touched :)
lol I've been wondering who Luffy was eating with, I didn't realize it was Naruto.
Yeah, I saw it on Naruto's 700th chapter and was like, "THAT'S THE STRAWHAT!!"
Then Oda sensei did it for Naruto too~
Wooooh Yeaaah~ Did you guys see the one piece tribute drawing to naruto and naruto to one piece?! I was surprised~ xD
