I just finished with the 5th episode and so far it has been so good. They haven't revealed or explained much of the things yet. However this show does have that quality to become a prominent show. I've always been stoked to see tournament in any anime and this show has given me that in initial episodes.

Animation and characters are eye candy of the show. Especially animation is really clean and slick.

Opening and ending soundtracks are really catchy.

Seems highly promising, so for now I'm gonna continue with this.

Arigato!
