The art is barely serviceable, especially with proportions and perspectives. When it gets it right it's decent, but boy, does it often get it wrong.
The writing is also cringy, and genuinely thoughtless, as characters often go way further than necessary to accomplish something, for no good reason other than to maybe hit some trope checklist—and not a very good trope checklist!
By chapter 2, the MC (main character, who is 41 when he gets isekai'd) is reunited with his long-lost crush, who liked him before she died and was reborn into the new world ahead of him. She liked him too, and wants to marry him. He says yes, then she asks to be his slave. Why? Who knows?
Then another girl, in chapter 5, who is a slave to start with, wants the MC to buy her because he is ridiculously strong, and will be useful to her. Her price has been recently raised to 5000, and he disagrees, saying he'll pay 7 times that, despite having literally balked at 1000 a few panels earlier. Then he nonchalantly says he'll somehow figure out the payment.
Oh, and apparently having sex with an adult (18) who looks her age makes you a pedophile... somehow. But the 10 year old who looks like an adult? Yeah, for some reason that doesn't. I'm actually angry here, this MC is disgusting.
Logic is thrown out the window for some of the lamest drama I've ever seen. I mean, all artificial drama is lame, but this manga manages to fail at even raising the stakes with it. The writing is so nonsensical that no form of urgency is ever established.
If you're looking for a trash story to not take seriously and make fun of... this would have been it without the MC bedding the 10 year old. Now I'm saying avoid it, there is nothing that will redeem this MC.
