if you guys noticed in the last chapter, when hidan got out of the circle, he quickly yelled for help to kakuzu, but he didnt react at all. the interesting part is the conversation after hidan's head was cut off. he begins by saying that kakuzu let that happen because he was slow. kakuzu's reaction was hidan shouldve asked for help earlier. and if you noticed like 2 chapters ago, when kakuzu snuck in from shikamaru's behind, the punch didnt even connect. that just shows that kakuzu really is one slow guy. kakuzu is probably a character that has a massive power, but in exchange, is slow. if the fight goes on, team asuma might have a chance to beat/defeat kakuzu, but they need shikamaru though. shika can tag kakuzu with his shadown bind jutsu if kakuzu doesnt pay attention. EDIT: oops i forgot to add one last sentence to last paragraph, im going to add that kakuzu takes time to unload his massive power, hence why he couldnt help hidan right out.
