Should I read the manga?

The manga is madami 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 pag-ibig knowing what good fights are coming up in the anime, makes it all the better to watch.

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