Story - 6/10
To start with, the storyline had quite some interesting themes that could have gone into so much exploration. The idea of a doppeliner system was quite a unique idea and I thought, had a lot of promise to it. However, the actual anime itself, in my opinion, failed the actual storyline. In 23 episodes, I would say, is a good number of episodes to sum everything up, however, there were many character introductions that were extremely random and there were random villains here and there that were totally unnecessary to the entire storyline but were just there for show. For entertainment, I understand it is just for *show* but it verged on "filler-esque" and I was sure this was something the anime was not aiming for as there were no filler episodes. I would like to say however that this anime scored points for me in terms of action but they could have done much more with it still. Some action scenes seemed repetitive. It is funny to say that there was no build up to important scenes when necessary and there WAS build up when it was completely useless to put there. I do point out however the anime had some good plot twists, so that's somehow a plus because the unpredictable is always nice sometimes. However, there were certain things in this story that thought should not have been there such as some what I would call, "flat romance". Sure, just a side theme to the story, but a pretty bad choice and could probably do best without. Either do a side theme properly or just leave it out completely. And in all honesty, this anime was verging on anti-climatic.
Animation & Sound - 4/10
I would say the animation was not too shabby. But honestly, there is not much to say about it. Nothing noteable. It was just standard. On the other hand, for sound, the music and sound effect selection was pretty bad. The battle themes pissed me off quite a bit. It was very off-putting. The genre of the music was ok, but the choice of song and effects were just horrid. It just seemed very out of place. However, I did enjoy the opening and ending themes. I think those were pretty spot on.
Characters - 4/10
There were some very interesting characters, but the actual interesting characters were not explored. On the other hand, most of the boring characters were the main characters. Keita, the male protagonist pissed me off quite a bit throughout the anime for various reasons. I'm not very "for" the idea of this kind of character as a male protagonist. Kuro, I quite liked as she had the most background. But everyone else just seemed like empty shells to me. I also have a confession to make. I wish Akane was not part of this storyline and could have gone with something else. There was something about her that just seemed so lackluster.
Overall (Personal Opinion) - 4/10
Basically, I liked the action as I like action animes. And I like the idea of main characters getting stronger and defying the norm. I don't mean to be biased, but I am saying this because I guess I am, but I just really, really didn't like how the story flowed. It just felt too coincidental for the sake of the story to go somewhere. Honestly though this anime could have done so much but they just didn't do it. You don't know how much I was face palming myself by the time I was finishing off this anime. I just wanted it to end and then tell myself, well great, that was a complete waste of time. For me that is. I understand some people might have liked it, but in terms of what the anime was trying to *do*, it just didn't do it for me. For an anime that could have so many possibilities and so much potential, this one just epically face-planted. Literally.
