I am SO freaking tired of this show! It's just SO OVERHYPED I couldn't resist but to share my thoughts with this review. People keep saying that the manga is SOO good and stuff but I am reviewing the ANIME, not the manga, so those manga readers could shut up and accept the truth that the first season is nothing more than a 6!
Story - 5/10
Tbh, just seems like a bleach ripoff at first but changes to something a little more original. But again, it's just like an average shonen with a demon-possessed main character along with his rival and friend and a girl to complete the trio. Also, not to forget the playful overpowered sensei.
Art & Animation - 8/10
The art and is very close to the Manga and the animation by Mappa carried it for me.
Music - 8/10
There are some very good soundtracks used in the anime which do a pretty good job to support the environment.
Overall - This show might be a good suggestion for someone who likes their shonen.
Mappa did a pretty good job animating it. But the ratings this show has got are definitely not justified.
