I read only 5 volumes and I have to say, it's interesting. It grabbed and clung to my attention since the first volume and I was thinking of buying it. However, looking how other people say the ending is rushed, it just add a blow to the idea of having the hardcopy of it. So I'm going to wait until I read the last volume to decided.
Sakurai Mikito is your basic average kid, who gets bully and never fights back. But don't think he's just your normal weakling. Underneath that bullied kid is someone who puts other feelings before him, hence why he doesn't fight back because he doesn't want to hurt someone. That caught my admiration for him when his childhood pointed that out.
So when a mysterious sphere, Zakuro, enters him and ask what he desired, Sakurai thought about getting stronger to protect his childhood friend. But Sakurai gets the urges to eat humans and view them as meat! Apparently Zakuro have a different idea of getting stronger and turned him into an orge. He finds himself thrust in the fights of orges and humans, and even battling himself to stay human. So the main question of this series: Is Sakurai going to stay that way, or will he find a way to turn himself back into human?
Storyplot, awesome. The fights? Awesome as well. Both weave together into an attention-grabbing manga series and makes the readers craving for more. More also, the twist in volume 5 doesn't seems to make it any better as I anguished for the next volume.
The art? The cover looks different from the inside. Looks like Acrylic painting, yet it have it's own texture and style that seems to sit well with me. The inking is done in an extreme contrast and the screentones are done in moderation in the midtone grey, so the beauty of the black and white contrast really grabs my attention. Watch for a few of them through out the series. There's a favorite one of my own, but I'm not going to ruin that for you and let you find your favorite.
Character development is on the top with everything else. Sakurai intends to stay human (as we all predict), and it's interesting what his mind setting is and his view in doing so. You'll grow to love the characters and with the twist, you feel a bit despair because you don't know who's on which side of your liking.
So my rating is high for the time being. I'll have to see how is the ending and I hope the ending doesn't make me change it.
