I read the current translation for the novel. Despite the translation being hard to read, I'll forgive the novel translators for that. This story is incredibly bland and suffers from really bad pacing issues. At points I feel the author forgets about the age of the protagonist and only brings it up whenever it's convenient for the author to do so. I suggest reading something else instead of wasting your time with this. If the manga actually fixes most of these issues, I'll be surprised.
