Naruto 309 page 13 | One Manga
Well i was remembering about Sasuke's entire array of techniques displayed...and i realized...They never showed the technique at the bottom left Panel...He was stopped by Orochimaru. Sasuke never again used a technique with those hand gestures (raised one hand after doing a seal). So do u think Kishimoto forgot about as Orichimaru said "That Techinque"? OR was it one of his Chidori Manipulations?!
Well I Just wanted to see if anyone thinks that this secret new technique was shown already...I think its a powerful lethal blasting technique (chidori/raikiri manipulation) that he'll show against Itachi (IF kishimoto remembered he put that there[Hopefully he will])
