The anime's keeping me interested so far- it's really pretty to look at, the fanservice has been really minimal, and the characters have been fun.
Probably the only complaint I have is that the pacing is a bit slow at this point, but it was like that in the manga as well, so it's just a small thing.
I hope if they adapt 2wei they keep the fanservice to a minimum like they are with the first parts, as while it kept me hooked the whole way through, I really didn't like the fanservice bits. But I think that that'll be interesting too once it gets adapted.
As for the manga, I like it for the most part.
The only part I really wish would be different is the fanservice, but other than that, it's a very interesting read.
Back to the anime though, I'm loving that I get to see Luvia animated for the first time, and I'm loving the holy living hell outta Ruby thus far.
So yeah, it has my endorsement.
The fanservice is really minimal thus far and it's fun, so I recommend giving it a watch. I recommend the manga as well, but the fanservice is worse there, so especially in 2wei, just a bit of a warning there. Still, it's fun, fanservice aside.
