I mean, take for example the moment when Akira discover the elf (forgot her name) :
Akira is in the dungeon on the HUMAN continent, pretty far from the elf continent but coincidentally, a slime had eaten Elf n°5720 without fully digesting her, conserving her ALIVE and UNCONSCIOUS. Then when she wakes up, they are weirded out then exchange a bit of food, start calling each other by name (Because God Eye, bitch) and then they suddenly work together perfectly like it's no biggie. So, um... How did she get here? In that slime too. How did she dwelve so deep into the dungeon without so much as an issue with the bosses? But get fucked by a slime?
Or maybe earlier, the princess got some cursing crystals but ummm... How do they work? Where are they from? Even just a little piece of info could give details about this world.
Not even talking about characters that just appeared out of convenience. And not even mentioning... The whole Elf Arc that was so rushed that it felt like unecessary drama between Elf n°5720, n°5721 and n°5722. Resolved in like... Too many useless chapters. In resume, Elf Sis is sad that her Big Sis was praised and because she doesn't understand why, she just complains about it and use charm magic to turn everyone on her side, then Grandpa Elf suddenly goes like "I deleted one of your memory but it's fine."
Not even talking about the "mobile" behind the Royal's acts which seems to be just Greed and War.
Not even talking about the classmates' part.
And I can go on. But I won't.
