I disagree, the three main characters are likable and the romance angle is well-played but everything else screams of mediocre. Kanno's only good soundtrack after Wolf's Rain was Aquarion's, this is average and forgettable plot. The character designs are not appealing, they're fucking eye melting. I hate the profiles and 3/4 shots of them.
I think Frontier's OST is better so far than Aquarion's (which was good, but nothing in it ever leaped out at me the way the BGM in Frontier does)
And character designs are opinion, not fact.
