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...
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.
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,
It’s been some time since Raccoon City, the origin of the T-Virus outbreak, was wiped off the map by the military. Umbrella Corporation’s stock plummeted and a new pharmaceutical company called WilPharma has risen in its place; however, unlike its predecessor, WilPharma is working on a vaccine for the illness that turns humans into bloodthirsty zombies. Claire Redfield has just landed in WilPharma’s town to visit a friend when she finds herself in the center of a zombie-filled bloodbath. Leon Kennedy and members of the Special Response Team are called in to save Claire and the other survivors from the airport, saving an important member of WilPharma in the process. What has caused this new recurrance of the T-Virus? Claire and Leon must get to the bottom of things before nefarious foes are able to carry out their plans...
If you're a fan of the zombie genre (which is the only reason I see someone watching Chainswa Maid), then I recommend you check out Resident Evil: Degeration. It has better visuals, an actual plot, and a ton more zombies.
