Story (7/10)

- Concept (4/5)-
Dark, gorey, unexpected and unique in its own way…and at some point, philosophical. Compare to other psychotic manga or anime, this would probably be the cutest. Somehow, in a way, this manga is like a more subtle version or the shonen version of Gantz. Instead of badass science fiction, a badass fantasy and instead of having sex, the oniichan would satisfy his imouto by letting her eat him and enjoys it.
It is not just mindless gore. The manga would actually make you think how the pupa resembles the two siblings’ life – a sort of parallelism between butterflies and the cycle of human darkness. I am not sure whether or not it’s just a coincidence but the manga reflects a bit of Sigmund Freud philosophy. There are other philosophical resemblance such as nihilism although it is indirectly stated or shown in the series.
Perhaps what makes this manga good is how it, perhaps accidentally, combines gore, violence and psychotic ideas with incestdom and fantasy – abusive parents, siblingly love and gauging out one’s eyeballs and turning into monsters. It is a rare combination but not completely unique. There are other sweet and psychotic hentai out there but this could probably in line with one of the good ones even if it’s toned down on the hentai side.
-Organization (3/5)-
It has a very good phasing. It is not as abrupt that of its anime adaptation. It gives us more depth, insights and gore to spare. It has good timing with the audience reactions, assuming that the audience enjoys such things. A good grasp of techniques and devices – how the author inserts light and fluffy moments or jokes in the middle of a gorey story without making it seemed forced. It’s good but still needs improvement. I can say the same thing with the cliffhangers. The readers need more impact to make us want to read more.

Art (7/10)

-Memorability/Originality (6/8)-
The characters seems a bit generic but they are seemingly memorable in a way with the use of the weird looking hairpins and scars. Gore, darkness and blood. Scary looking creatures, cute and kowaii stuff toys. It suits the lightness part of the manga but at the same time its darkness.
-Quality (1/2)-
It’s okay. Not to that screwed up but not epic. Lacks background at some point, but good emphasis on the characters. Good direction and point of view.

Characters (6/10)
Relatable to people with siblings and those who are into incest but the characters are generic and unrealistic. Although the love between the two is good and as well as the psycho path tendencies of the characters. It lacks dimension, power and strength but how the characters transforms or develops is good and how they show scenes in the first person point of view saved the series from being a sucky one.

Enjoyment (9/10)
Although it can be generic at some point, I enjoyed the gore, the blood, the violence, meaning and the love between the two siblings. The desperate looks on the characters and how there is much violence, gore and more gore. Did I mention how bloody it is? It may not be realistic but anyone who enjoys incest, gore and philosophy might enjoy this.
