thank you for the reply, i will try to insert one of these in my new bio i'll make.You cant. Unless you throw the Kunai with more speed than the opponent can track. As freeform throwing a kunai is(if i rememebr rightly) only as fast as your base speed, you'll never be able to throw one faster unless you using Eight inner gates or something. You're best off with a Wind Cj or a Lightning cj along the lines of "increases the speed of the kunai x4 your base" of something along those lines
But Eight Inner Gates sounds too complicated so i'll go for the wind one, an element i can have.
