Blah blah blah LOL. The Kages volunteered thier services. Sasuke was not even begging for thier help any way. "Of our current battle strength..." LOL. Current means present. At that moment there was no Sakura there. Simple as that. Featless Darui is apparently waaaay stronger than some one who wrecked the shit out of Kaguya. LMAO. Trollings is so obvious in NDS.
Wtf is wrong with you kid? Darui's feats are so lame that in comparison with Sakura it looks like he got no feats Boohoohoo lol. Read the manga with your brain next time and stop pulling sh!t out of the rear end lol. Sakura slapped the mother of all shinobi, darui is nothing before her, she will just throat snaps him off in a fight.
