Seems like GTO meets Kamen Rider. It's got Natsuna Watanabe, so that's nice. Unfortunately, the action seemed mediocre...?
Spoiler
I was expecting some badass kicking from the main character, but everytime he gets into a fight he just drowns in his own angst and lets himself get beat up, like a punching bag for the antagonists to let out their stress before befriending then.
Well at least it had Natsuna Watanabe... though she was a little stiff in the movie.
