This Isekai had so much potential, but in the end it is just straight up hentai.
Here are the tags:
Rape, Moral Degeneration, Guro, Demons, Humans, Mind Break
Joke aside. The art style is fine I guess and the plot and world building does make the reader question how things came to be and how they will develop. There are several obvious messages from the author with a educational purpose like "Confidence comes from Actions and not Actions come from Confidence". The MC is hella edgy with that eye, but at least the side characters are comedic. My obvious criticism is the whole hentai stuff. It's so distracting from the actual story and I really feel like I'm reading straight up a ero-doujin about monster rape and moral degeneration. Also the MC kinda disappoints me. I mean I'm glad that he doesn't have a complete broken ability that allows him to go through challenges without effort. However I do expect a little bit more from a "Trap Genius". It's not like his traps are to bad, there are some clever ideas and tricks behind them, but I kinda expect more mind-blowing traps from what they built up in the first chapter.
So is this manga recommendable? Only if you can enjoy/ignore the hentai part and focus on the "plot" with classical supremacist.
