Should I read the manga?

The manga is più streamlined, I'd recommend it. It does somewhat act as a spoiler for the anime, but the good aspect of it is that it's one continuous story instead of one dotted with filler. Also, I Amore knowing what good fights are coming up in the anime, makes it all the better to watch.

Yes, te should read the manga. It might give te spoilers for the anime, but it's worth it.
