This technique requires that the user have at least 1 chidori or raikiri effect active (including Chidori Nagashi). The user fires 2 chidori senbon at targets within range, each dealing 100 points of electricity damage. The chidori senbon automatically hit regardless of concealment (barring total concealment, in which case the user must still guess the square) or cover, and cannot be avoided with instant action defensive technique such as Kawarimi no Jutsu. More than one chidori senbon can hit a single target.

Empower
The user can increase the number of chidori senbon by 1 every point of chakra spent in this technique, maximum 1 per level or 10.
