This is more of a spin off that a continuation of the actual aquarion series. But overall i enjoyed it. It's not the best but it's not bad either. For those who are new to the mecha genre, this anime would be a good start. Art? Sure it ain't good, but it shouldn't be the one factor that deters you from watching it. Music/Sound? There's no Akino/bless4 so far, but May'n makes it up for that imo. As for the seiyuu, they fit the characters, that's pretty standard. Characters, this is where Logos shine. they are all weird people with funny aspects to them, and their personalitymash well together. The best parts of the episodes is always the interaction, Akira being totally disconnected from the others from his savior obsession, Maia not knowing anything other than her mission, etc. They make good use of their quirks and made their interaction entertaining.

Enjoyment: Refer to Characters.

I personally give it a 9. I like good/entertaining characters, and they gave me the latter, in a silly premise.
