Blue Exorcist (Ao no Exorcist) volume 8 contains chapters 28 to 32 plus a question corner with the author and characters, and an extra 4 panel comic!(with a special drawing of Kuro in what would be his human form!)
It is rated T+ for older teen (16+) due to violence, suggestive situations and some adult themes.
Once again, continuing from the Kyoto arc, it's Yukio vs Todo in a 1-on-1 battle while the others hold back the demons and Rin and Suguro head towards the Impure King. But the hardest battle is being fought by Yukio, not with his opponent, but with himself as he starts to doubt if he really loves his brother.
What I really love about this volume is how Mephisto is just sat there watching, he's so funny!
The cover of volume 8 is my favourite so far and inside is a colour page where we get to see it zoomed out and Yukio is stood behind them. And the image on the back is also adorable~
I didn't spot any mistakes and the quality is good so a perfect 5/5 from me!
