Name: Wind Barrier
Rank: B
Type: Ninjutsu
Elemental Affinity: Wind
Description: The user creates a large wind barrier around anything it wants, but it cannot create barriers far distances away from the user. If in battle and the barrier is created, the opponent cannot escape, nothing can enter or leave, only will the barrier allow the user to enter or leave it. But the barrier does take a toll on the user's chakra. If an enemy tries to escape the barrier, it'll cut whatever part that enemy uses to escape. Hands on barrier will cut hands. But kunai will just reflect off the barrier and fall to the floor.
