When Utsutsu and Yume were young, they were physically and emotionally abused by their sadistic father; and now that they’re older, Utsutsu swears above all else that he’ll protect his little sister at any cost. So when the girl is infected with the mysterious Pupa virus, causing her to turn into a terrifying monster that eats anything around her, the boy does the only thing he can: he offers his sister his body and flesh to consume. He won’t die, for Utsutsu was also infected with the virus, giving his body the superhuman ability to regenerate from any wound, and making himself the the perfect food source for his beloved sibling. Though nefarious researchers and doctors are studying their every move, Utsutsu will do whatever he can to keep the pupa inside of his sister from emerging and killing them all.

    Honest to God garbage.  Where to even begin??  The plot was stretched so thin, and all the explanation was so vague that I'm not even sure the author understood how everything fit together. It was so seemingly random, that at some point it just felt like the mangaka and the editor must have just been throwing out every possible idea and said, "Why not?". The parts that did make sense were so tacky,and overplayed that I had next to no interest in it whatsoever. A lot of the parts that are explained, are also gross feeling (like, oh, let's say, a woman taking the sperm/eggs from two siblings and implanting it into her own body in order to force a child between them?).    The characters were dull, with each character having basically one thing about them. Utsutsu has an extreme sister complex. Yume is a monster. Their father is violent. Maria only cares about research & Hotoki literally gets off to his own sister. And that's essentially IT. There is absolutlely no character development worth noting, and no real intelligence or drive to any of their actions.     The art wasn't terrible, but was definitely not distiguishable or noteable, and was very lacking in some places. There was no characterizing art style, like One Piece, or Soul Eater, but I didn't expect there to be in the beginning, anyways. What there was a lot of are images of two siblings eating each other in some very purposely erotic ways. Lots of scenes of them hugging each other, scenes of them being completely naked around each other, and also scenes of them hugging each other while being completely naked. Y'know... Just normal sibling things.. ((Big yuck)). If I walk away remembering anything about this manga, it will only be how truly bad it was. tldr: A nasty waste of time catering to people with sibling complexes while being disguised as a psychological manga.


*I do not mean to undermine the existing review, I just wanted to add one of my own.* Warning - this manga has high gore content, and it is not "cleverly censored". There is a reason this is listed for having "mature content". It is pretty disturbing, but truly interesting. If you're into gore style horror and a whirlwind plot that grows more complex as more is revealed as chapters pass - Pupa is something I recommend to you!   As the reader, you're introduced to the back story from the viewpoint of Utsutsu by way of adorable teddy bears in tragic scenes. You move on to Utsutsu and his "sister" going about their lives together without their parents... It is clear Utsutsu has a sister complex and Yume is very attached to Utsutsu as well, but in a way that's less incestual and more like a very loyal and loving dog.  Their father is a Yakuza, Shiro Onijima, whom people in the community fear greatly. Their mother is Sachiko Hasegawa, whom Shiro married when she became pregnant with their son at the age of 16. Their relationship becomes extremely violent when Shiro returns after a 5 year trip to see a SECOND child, whom he assumes was born of an affair, which is probably why he turned so hard towards his once cherished love.     One day, Utsutsu and Yume walk home from school and bump into a strange woman who warns them to "leave before the red butterflies come". Utsutsu then sees their father parked waiting for them - he has Yume go on ahead to the park without him...This is when tragedy strikes, or so it seems from Utsutsu's point of view...                                      I found the storyline intriguing, overall, but a little slow paced for my liking. I could have seen this series lasting a bit longer, or at the very leastI expected a lot more from it's anime adaption...If you don't have a weak stomach - you may find this just as interesting as I did. In closing I'd like to mention I'd be happy to explainany confusing things in the back-story or overall.*Good luck finding the "completed" series, it seems to have fallenthrough the cracks - such a pitty.*Stay Creepy,~Krovyu ***SPOILER ALERT***The incestual undertones, portrayed by Yume feasting on Utsutsu in a way that makes it seem as if it's an euphoric experience for him, are a little weirder than simple sibbling incest - Yume is a genetic copy of Utsutsu's mother Sachiko.Yume did NOT get "infected" on that day in the park, she IS a Pupa and she simplyawakened and left her shell. Like a larva transforming into a butterfly.Yume is a "monster" - she is not human.The reason Sachiko gave her the name Yume was because the events that transpired after Utsutsu's birth surely had to have been some horrible nightmare, only a dream - right? Sachiko feared Yume would harm her precious Utsutsu and has a difficult time keeping her sanity due to various events that occur further proving Yume is a monster. Shiro thinks Yume is a bastard child and takes out his rage and feelings of betrayal out on Sachiko as well as the children. Perhaps the reason he even beat on Utsutsu was because of Yume's existence Shiro may have wondered if he was even his son either because surely she wasn't his daughter.Sachiko is believed, by the duo, to have left with another man.In reality, she finally lost her mind and remains in a hospital over a pupa research lab.Shiro truly did abandon them, but in his own twisted way it is clear he still caredabout his wife and children. (It truly seemed like relief hit him when he heard ths story of how Yume came to exist, knowing his beloved had indeed been faithful. Maybe I was reading into things too much, and his facial expressions, but that's how I saw things.)
