Description

A world where the Demon King was defeated by a Hero that came from another world. People carelessly forgot about their fear of the Demon King and of monsters, living in peace. In a forgotten and run-down cave in the mountains, a new monster that should not have been born was given birth. The monster’s name was the “Black Ooze”. It was nothing exceptional other than its black color, an ordinary slime. However, this slime had the special characteristic of being able to take the abilities of the living things it swallowed. It preyed on an insect that had paralytic poison, as well as other animals. Following that, it attacked a human, obtaining his knowledge and Desire. Before long, the monster established its target as the female mage that came to explore the cave. This world still wasn’t aware. A Monster Was Born. 4f2u5e

Looks great, problem with H is they all tend to be on the short side, lacking substance or development. 7 volumes is a lot of entertainment.

One of the worst things I have ever ready ... No it WAS the worst thing I have ever ready.

I read 5 chapter and I was done. This was the most disgusting thing I have ever read. And I will be honest, I tend to like stories that use tentacles creatively .. but this .. this was a hard NO!

The portrayal of women and humanity in general was insulting and I wish I had never read the 5 chapters I did. Left nothing but a bad taste in my mouth.

This is pure doujin hentai and can't be considered a manga.

I be sincere. I was interested in the beginning but then I get tired of the repetition. The author write story for doujin hentai and not story that can be considered for manga. Even if this is considered a mature manga it focus more on the perverted thing extremely to much and keep repeating the same formula over and over again. It makes the human do many stupid decisions just for the slime to beat them easily and rape all the women in the world that will eventually bring the extinction of the race. I have fast read the novel so a know where the story goes. Even if the author extended the story just for the purpose of making it longer; it still the same thing over again even if it put some twist in it. The novel is not finnish but is obvious that at the end the slime wins and humanity goes to be exting not before the slime rapes and break all the women and kills them in the end because if ultimate objective is survival, power and increase is number until theirs nothing left.

This series is so fcking disgusting! Because its all about rape, 95% of the story is about the slime raping several, dozens, hundreds, thousands of women at the same time, for days, months, years, NON STOP. When the women gets tired of being raped, and faint, he keeps raping them even while they sleep. Do they starve to death? Nope, because the same dck he uses to rape their mouths non stop, it also uses to feed them (it's a d*ck and a food dispenser). A normal female human can produce one egg per month, but once this female fall on his hands, she can be impregnated and give birth to another one of him every few days. Now, multiply this for thousands of women being raped 24/7, for months or years. Even if the slime let the woman take a bath; that still not enough for theirs health. They don't exercise, rest properly or eat properly (food is not gonna last because the slime just consume everything without raising livestock or plants; it just take); their bodies are gonna fail eventually. Also the author thinks that woman's can recuperate very fast after being violated non stop by the slime with no consequences on theirs bodies; showing a few walking and even fighting when they shouldn't be able to move properly and have any strength to fight.

The main character is the most ridiculous character ever written in manga history. He is the epitome of the plot armor concept. It is always prepared to deal with anything that is thrown at it. No one can defeat it, be it the strongest adventures, the biggest kingdoms armies, the fabled heroes from another world or even the gods who summoned them. They all die horrible deaths (the men) or become f*cktoys (the women). It always have on it's hands the exact kryptonite needed to easily deal with all adversaries that show up because the author makes the humans do stupid decisions so the slime can always wins even the ones it never saw before.
