This anime is one of the BEST for Spring 2014, though its only 11 episodes. Another epic light novel series adapted into anime... Thats why it so short!! Story is great, not your typical treasure hunting story. Very unique way of hunting powerful treasure... The graphics is superb!! welll in the ruins that is.... and on fighting scenes too... every blow will make your breath stop!!! You will get your Jaw Drop everytime they open a ruin, you might wonder that a huge budget was used for just the ruin entry part....Characters are good... you can probably remember them even after the show... especially Nanana-chan

So, overall... This anime will surely make your day! I promise that you will regret missing this show.
