black gem can trap MORTAL souls, not only human but khajit, orc, mer, etc... sapient species

the author must have deep pockets to repair it...

Ui BEAM!!

a good concept but too much sex and too op from the start for my taste.

A good story, truly, but I don't like where it is going, heed my words, you have a great skill, there is no issue. Just my own opinion, I don't like the present yet cherish the past, but wont'tbe there in the future. A very good story while my interest in it lasted, for me. Good luck.

PD: forgot to mention, do not mix too many anime together, focus on one and maybe two. that makes less variables and easier to imagine the outcome, that said so, I have to mention that you have no idea of the power scale of the anime or lack the necessary information, improve in that and good luck.

It's a good story but not much my taste with letting the readers choose some of the settings for this story. You write for yourself, not to please your readers, that is optional. You must love the story before your readers, that is what makes stories special, as doing as you like lets the world and your imagination flow without having to consider the thoughts and opinions of other people than yourself.
