(I am a German => my English sucks, don't complain XD)
Because there are only four episodes released yet I can't really tell you how amazing the story is because right now it is only at its beginning but so far it seems to be very entertaining and full of action. The fights are pretty cool and exciting. But so far I still don't understand what kind of powers the main character is able to use and why ruri is able to transform him with random jewels (not explained very well) but maybe that's just stupid me. While story is a bit confusing at times the characters are so adorable. The main character is ab bit boring to me, but ruri and her servant are so cute together and the other girls of the gem (or stone or whatever) club are so cute. Overall the design and the animation are very well made and the monsters and transformation are just amazing! Right now my only hope is that the story develops in a way where everything solves out in a logical way. Up until then i can only recopmmend this anime to you. (show less)

This anime jumps straight into the action with the first episode establishing the main characters and thier powers. The following episode rapidly builds on the storyline, further developing the good characters and the bad characters. The dialogue is wonderfully set out, making for an exciting story and wonderfull characters. The animation is excellent quality making brilliant combat scenes. The overall entertainment is good so far, and seems likely to get better over the next few episodes. Definitely download, although be prepared to wait for the next episodes. (show less)
