Didn't we already have a similar technique before in that you do pretty much the same thing? I might be wrong of course, but it so reminds me of a ninjutsu technique, however this one is a bit more complicated then it looks like for one simple reason, it is just a technique with many 'parts to do' meaning that it will slow you immense and, unless you don't distract your opponent/your target with something, it won't land and you will be damaged badly if your opponent plays his cards the right way. The range is the only good thing of this technique in my opinion, other than that if you manage to distract your opponent it's not a bad technique, it's just something that I won't use in a fight. The best way to use it will be to follow up with a genjutsu and a technique beforehand and use this technique as the final third technique or rather for the final 'blow'. The countering part is pretty easy and straightforward, I don't even need to mention it but I will, you can basically use the timeframe to your advantage and use elemental ninjutsu or taijutsu/kenjutsu to interrupt the following technique; you can of course also overpower it. B rank or higher would work fine and I doubt anyone will have problems with countering just basic and straightforward technique.
The only cool thing about this technique is the name of it. Pretty much that yeah. It's once again one of these weapon ninjutsu technique which terribly annoy me. If I want to throw a kunai I would most likely do it by free form throwing a kunai, I don't even understand why there are such techniques as this one, but yeah what can you do. Not to mention it's only usable in short range, I mean come on you can free form a kunai in any range but you can't use such techniques in medium and long range, that's a shame. The countering part is easy, e.g. : earth shield/dome, wind blast, wind wall etc. I would rather strike the opponent with lighting release because lighting is the fastest travelling element after all and it will work good here. I really don't see myself using this particular technique just because you need to heavily rely on the distraction before this technique and I have really no idea how someone will let themselves get hit by such technique. Not that it's a terrible technique, it's just not my style, that's all.
