The main character summons a giant pe*verted octopus, probably from some other story. I'm not sure what it's from but I'm sure that other people figured it out. Then the main character summons a sword that people say is from Bleach. At this point I think it's still okay because monsters and weapons from other stories are commonly used in games, animation, and novels. Even if they're unique weapons and monsters I'm not going to fault them for using them. However, the main character ends up summoning Gaara from Naruto and he seems oddly helpful towards someone who gave him what would be a tiny offering to someone of his level. From the main character's narration we can expect to see a lot more copyright infringement in later chapters.

Gaara from Naruto showing up, with the MC being all like "oh yeah, I know how to deal with this summon, BASED ON MY POST-APOCALYPTIC KNOWLEDGE!!!".

He f*cking summoned Blue Eyes White Dragon

I say that the author keeps the story intense by forcing scenarios happening one after another, sending monsters here and there, resuming the killing and stuff then when you thought they can rest there comes an unexpected Vine Demoness out of nowhere. It is so forced. How is a Vine Demoness an insect? He specifically said that they will be facing insects and low levels at that anyways so demoness appears, heroes rescues beauties with plot armours and stuff, I really don't have anything against plot armors, but turning you into a girl's appearance bit by bit really made me vomit. His first plot armour is a sword "Frost Moon" it turned his hair white and made his skin as white as snow making him look like a female as the novel said, then the demoness core that he swallowed now is making him effeminate adding to the fact that it decreased the size of his P*nis? That blew me 200000 miles away from this novel, I can sense from here that I will be facing gay scenes from then on, maybe author is going to make the MC receive men and women, it might be ok for some, I don't judge some people's preference but it really turned me off.

Plotholes start piling up early and in the end thousands of world are faced extinction because of MC his cowardly nature and hypocrisy. Because he does not want to take responsibly for either of the woman he fkd or rpd.

He even called every s*xual encounter he had reverse r*pe even though it was obvious he forced himself upon several of the woman.

Alright to address some other reviews which have misinformation. The book tags are right when they say there is no Netorare. The Main Character does get transformed into a woman but the worst contact he has with another male is hugging and kissing. The main character is never r*ped by a man, I can see where the reviewer who posted that got confused if they were skimming through the MTL as that was brought up multiple times but it was actually the MC's summoned pet using an artifact to screw with "The Male Protagonist" who had fallen in love with the female image of the main character. The main character is an absolute idiot and the author points that out many times.

The actual biggest negative I have with this book is the Main Character's rigidity on trying to limit the size of his harem and he is pretty scummy in how he does it at one point having s*x with a decent-sized (10+) group of women who have one-sided feelings for him then erasing their memory (oh and all the girls get knocked up too, for good measure). The s*x was to help them become stronger so they would be useful in the final battle in which they are completely useless.

To address some of the more offbeat things that users should avoid if it would make them uncomfortable. Their is fairly heavy BD*M added with pe*ophilia references as one of the darker characters makes a 10 year-old girl her s*ave and raises her as a "human dog" and the author is fairly descriptive on that and that girl also she is one of the girls that the MC sleeps with at the late ends of the novel when she is 13-14.

Other than that the novel is incredibly dark as the author puts in a lot of effort emphasize the cruelty of the apocalypse (rape, underage prostitution, betrayal, cannibalism, etc.) and the author will often spend several chapters writing about insignificant characters before immediately killing them off in the current tragedy.

The overall ending of the book is happy-ish though even the author admits how unpopular the book was during the course dropping from a 2nd-tier novel in China down to a 4th tier novel as he stated with only a few hundred subscribers near the end of the book so I could see it being easy for a lot of people wanting to drop the book midway.
