this was my first anime that i watched on subbed. the plot is perfect and the story is good too this makes this worth a watch you must have heard about anime know as "Infinite stratos" if you liked that anime trust me you will love this. i was addicted to this anime just by watching the fist episode it got my attention and i finished the series just in one day. there is nothing to dislike in this anime however, the way it ended is really something else. on last episode a girl just comes out of nowhere and claims to be Chidorigafuchi's sisterand then it says
to be continued....

you cant just leave fans hanging like that and this gives us the hope for season 2
i say give this anime a try you will love this.
