Honestly, I wouldn't watch this for the story. You can litterally walk away for a month or so and not feel like you missed anything other than minor stuff.

It is best to look at this as something to watch a bunch at once, or turn off your brain while you're watching. 

Story: There is some, but as I mentioned the show streches any story it has to a good number of ep. Like something that should only be down to 1 or 3 ep gets streched to 10 or so.

Animation: It is OK. Maybe not the best, but it is up there at times.

Sound: This is iffy at times. The main person peaks, the sound can get rough, but at other times it is ok. Things like the replay of music over and over and over is noticeable after a bit.

Characters: There is depth, but not by much. Like many have some back story, but how they act is very 2D. Their past is brought up once in a while, but mostly they are 2D.

Overall: You will know pretty quickly if you will like this show or not. I like it, but I can easily forget about it.
It's on the same line as mordern DBZ. Where you can litterally have an entire ep on people screaming and nothing happening.
