I would say that the world design was top notch. And concerning the main character, it's generally been at least an okay for me. Even though at the beginning it was kinda weird with the site loss and all, there has been a rapid character development and I love what am seeing. Just keep it up.
Nice story if one can read through the translation such as mistaking "she for he" though I love the character development not an instant op mc and he still had to train the powers he gained .
