There are a lot of spoilers in this review. horny teenagers might enjoy this but it's objectively a very bad manga. This is basically just hentai but very censored and worse plot. Every single chapter has nonsensical sexual moments, ALL the female characters are oversexualized and their only quirks are that they're horny af all the time and are always forced into sexual situations like getting naked and performing an erotic dance to share their qi or being forced into having f-tanari s-x in order to fuse with a spirit??? Every single monster also destroys their clothes for some reason. MC basically gets NTRed all the time whichis disgusting but he doesn't seem to give a shit and the ones doing the NTR are women or monsters.
The plot is so dumb, the MC basically becomes the strongest after a couple chapters. The MC has the power to make any magic he imagines into reality, so I'm sure he could go home whenever he wants to but of course he doesn't... The MC is a selfish asshole that doesn't give a shit about what other people feel, since he doesn't feel the need to tell his friends that he's alive and okay (instead he lets them risk their lives over and over in order to find a way to resurrect him). If he were even a half decent person he'd go and talk with his friends, clear up the misunderstandings and then help them go home if they want to.

I honestly don't have anything good to say about this manga, the writing is disgusting.
