I take my hat off for this young lad.
He turns normal chidori into a sword, long range spear, and little needles, combined with Sharingan its a deadly vital point striker. Plus using Chidori he tamed lightning by using Kirin.
As for Amaterasu, his doing the exact same like he did with Chidori. He turns Amaterasu into a shield with Susanoo, a sword and a projectile. Im looking forward to how he is going to evolve.
