Sakura's Belly Strike

You know who this is, right?
Yes, it's Sakura from the 3rd Naruto movie, where she happens to bear her midriff throughout the whole entire movie for some reason (I've never seen her do it before).
I don't know much about Sakura nor do I watch Naruto. All I knew is that she beared her midriff in the 3rd movie. And I SERIOUSLY kept expecting a moment like THIS to happen, where someone would attack near/at her bare stomach and she tries to suck it in. AND IT HAPPENED! I just found a clip on YouTube, and then THIS moment happened! She was battling some girl, and that girl just swung a knife right close to Sakura's midriff. Luckily, she sucked it in (or more like "pulled it back") to avoid the knife (close shave, ain't it?).
Goes to show you, Sakura: you bear your midriff at last, and now someone wants to target it! XD
