If you liked the Pupa anime, the Anime-Planet community thinks you'd like:
For Kouta and Yuka, finding the bloody naked young girl on the beach would change their lives forever, for better or for worse. Unable to speak or function as a normal human being, she is named Nyu by the duo, and taken into their home in an effort to save her. But what neither teenager knows is that this innocent young girl is actually a killing machine -- an experiment gone terribly wrong -- and it is only a matter of time before the murderer in her awakens again...
The plot of Pupa and the plot of Elfen Lied are nothing alike. But there's lots of gore in each anime. Pupa and Elfen Lied are both more serious animes with plenty of sad moments.
There isn't really anything linking these shows aside from the high levels of gore contained in each. But if you did enjoy Pupa and want something equally gory, and you haven't seen Elfen Lied yet, then you'll find plenty of gore, a much better plot, a better set of characters, nicer aesthetics....actually, it's just better in every single way.
Both anime have very similar feels and some sequences are near identical. Also they both have sub-plots dealing with torturous experimentation and a young girl having to cope with the monster within.
These are both shows that think excessive gore is equals horror. Both these show are condensed versions of their source material that rush and compress the material into something that is really unsatisfying to watch.
The plots are quite different with Corpse Party being about a group of students trying to unravel a curse and Pupa is about a girl that turns into a monster that eats her brother so she doesn't murder other people. Corpse Party has a little bit of a plot even in it is compressed. Pupa skips around to the point of incoherency.
Pretty much if you're just looking for violent anime with some really inappropriate fanservice then try either of these titles, although be warned the gore in Pupa is heavily censored.
Here we have two examples of shows that like to think that over the top gore is somehow the same thing as good horror, rather than trying to actually make the series scary through its writing or atmosphere.
They are both also pretty heavily butchered adaptations that rush through the source material with a staggering lack of respect. And while the premise in each aren't very similar at all, the only reason people will watch either of these is for the gore. So if that's your thing, you may find something to enjoy in both of these short series.
Over a century ago, mankind was devoured by giant beings of unknown intelligence and origin known as Titans – creatures that eat humans alive indiscriminately and for no apparent reason. The remaining population has managed to survive the last hundred years only by building a multi-walled city capable of keeping the Titans at bay, training military recruits to patrol the perimeter and gather intelligence about their mysterious foe. Eren and Mikasa have lived a relatively peaceful life behind the city's walls, but when a massive Titan appears, smashing the outer barrier and unleashing a wave of terror, their lives are brutally changed forever...
A girl and a boy lovingly sit beside each other in a park and lean in for a kiss, when they are interrupted by a man who pops up from behind the park bench, chopping the boy's head with an axe. Terrified, the girl runs from the boy's lifeless body as fast as she can, hoping to escape the carnage...
These are both anime with have a disturbing tone, excessive violence and not much in the way of story. Instead these are both anime that are content with showing creepy visuals with little or no narrative.
Bloody Date is a single episode Claymation short with no dialogue so its visual style is much different from Pupa, but there aren't many short horror anime out there, especially ones that are this violent. Bloody Date does have a story, but it's all told through background details and characters actions, whereas Pupa does try to tell a story, but it jumps around so much its hard to figure out what the hell is going on.
If you're going to watch these titles then go in expecting lots of gore, barebones story and some creepy imagery.
A maid tidies the house and prepares to 'tend to' the father of the house while his daughter is in the other room, when suddenly there's a knock on the door. A bloodied, frenzied woman screams that 'they're coming!' and promptly falls over dead... and that's when the zombies arrived...
These are both anime that are more focused on being gory and surreal rather than telling a coherent story. Both these are shows that seem to come from a very disturbed mind with their disturbing imagery and lack of explanation for anything that is happening.
Chainsaw Maid is single episode claymation short so its visual style is very different from Pupa which looks more like a traditional anime. Pupa also heavily censors its gore in the TV release. Also, Chainsaw Maid actually does have a story, but it is told through background details and character actions with no dialogue, whereas Pupa is just incoherent jumping from scene to scene.
If you're looking for anime with lots of violence and gore mixed with some surreal images that at least attempt to be disturbing then try either of these titles,
