Commissioned in death to save a world in peril, a tabletop RPG fanatic is reborn as a humble farm boy with the rulebook for the universe at his fingertips! Young Erich’s quest for an invincible character build will require more than his decades as a number-crunching munchkin, though. Even with power-leveled skills, feudal life is no cakewalk—especially when you keep drawing more attention than you can handle… Can Erich adapt to his strange new world before his worst impulses take the campaign of a lifetime completely off the rails? Let the dice fall where they may!
Seen plenty of arachne girls in different series. Always thought they were more creepy and repulsive rather than “would wife up”. Not my thing at all.
But this series proves one thing: There’s an exception to every rule. Margit is too good to deny.
Love interest of main character has lower body of a spider. Her character is cute but their romance scenes are super cringe. I do not want to think about how they managed to have a child together.
MANGA FOR SPIDER FETISH
Should have Ecchi tag
This should be marked 18+ I didn’t expect chapter 1 to be like that even though it didn’t show what happened still 😐
You need to read this one, even if you don’t like it this one has done a good job at being different. This one is worth collecting physical volumes of.
woow that’s weird!
an isekai with a mc who only has 1 wife! and no harem… he even has a daughter !
what’s going on??
I don’t dislike his wife being non human and he doesn’t seem ultra op. 3 chapters anmrent enough to judge but it starts well 
not bad, not bad.
As someone who doesn’t really care much about breeds/race. This one doesn’t really bother much about it either. I wonder what are the “monsters” be like if different races are being acknowledge as normal race like humans.
Anyway, good start for 3 chapters with an instant canon-relationship from the get-go. 
The first 12 chapters of this are absolute fire! What a world; the magic system is inventive, the economics and social hierarchies make sense, the magic creatures range from sentient to beastly, from malevolent to neutral, from mundane to supernatural. There is real romance, and drama, and adventure, and real responsibilities and consequences. There are new chapters now and more new chapters in the raws (chapter 16 just dropped), and a long novel, so this might go on for a while. I’m stoked and strongly recommend!
Summary: Isekai MC has a cheat skill system with real costs. He’s trying to level up without standing out, enough to protect his cute little sister and still adventure with his half-spider girlfriend (jumping spider, so cute) But an unexpected calamity uproots everything…
