I wonder why everyone seems to love this thing. It's honestly quite horrible, but perhaps my tastes have just been corrupted from reading too much manga and novels that this kind of thing can't be considered amusing anymore, or my tastes are just different to other people here.
First of all... where's the fun? I see a lot of things where the author is trying to make it funny, but I find it to be just about all low-level stuff which might make a kid laugh, yet I don't even smile, sorry, I've seen too funny stuff to even crack a smile at this shit. It completely gives me the feeling that it's similar to dragon ball, written for kids and that I remember enjoying when I was younger and couldn't properly evaluate stories. The art style is not just bad, it gives off radiance of childishness akin to a search light in the night. I don't really mind bad drawings, I've read a lot of stuff with horrible drawings far worse than this and loved it, but this is just dull, the style of the drawings and characters that show up are clearly aimed at kids, with mascot-like characters abound and childish-silly appearances of just about everything, it turns me off quite hard.
Oh, and it'd be cool if the demon was a tough loli instead of shota since it'd make all the escapades and stuff that character does way more amusing and cute, but that's just my preference and doesn't really matter. If the story here was actually good, that wouldn't have mattered. Well, in the end I guess I just picked the wrong manga.
