Ok I might have not remembered this correctly but I don't have the manga chapters with me to look it up. But what I remember reading in the manga a while back is that konohamaru and crew were gonna go on a mission and ebisu got a cold. And I THINK konohamaru was complaining because ebisu got a cold before their FIRST mission.

So if I remembered that part correctly, then the filler part they just added to nartuo:s ep 1 where konohamaru and crew were chasing that cat would conflict with the manga in the sense that it would not be their first mission at all if/when they animate the part i was referring to in the manga.

But my memory's a bit hazy on that little detail but I was just wondering about it. Any clarification would be apprecited.
