This series is so f*cking 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 d*ck 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 and deteriorate 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 goddess 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.
