The original story was to be honest crap/not so good. This story is not from the original LN author....and it still crap/not so good. This manga is only like 40% or less the same as the LN. The LN was ok, the manga..well for me is terrible. Waaaay to long winded. IN the LN the whole black thing was taken care of pretty quickly, not this convoluted mess
It's pretty simple really, the author just isn't that good at writing. Sure better then I could do, but it's still not to my liking (and more people seeing the comments). Though to LN left so little impression with me that I can't remember most of it. Again, it's a meh tier writer.
