This is just a little thing - I'm pretty sure it doesn't affect gameplay, but I wanted to bring it to the devs' attention just in case.

I noticed when doing Ninja Exam lv. 50 that the Neji I was facing had some weird animations whenever he dodged an attack. The blue sphere still appeared; however, Neji would punch the air afterwards, as if he had activated his Mystery skill.

This was not the case for my own Neji; his animations are fine. I also don't think I've had problems with this when fighting Nejis anywhere else - he was fine during my last Chase mission...
