How about Sakura defends herself inside Katsuyu until gates is over. Or Katsuyu splits into all her parts and Lee never finds Sakura due to the distraction of all the parts.Its not like Katsuyu can do much though. Lee is way too fast to get caught. Worst case scenario Katsuyu will have to spit her acid and let Sakura get caught in it as well. Can Sakura heal from that? I don't see lee getting hit any other way. The decapitation can occur in in the matter of seconds also...
