Comments of chapter undefined of I'm a Ghoul in Akame ga KILL!

I was reading a fanfic and remembered that there is the same fanfic. It's called Tokyo Ghoul: Rebirth, and judging by my memory, it can be judged that it was most likely copied and minimally changed to fit this plot (the same ghoul, Akame/Ezdem, etc.). I wouldn’t be surprised if when reading before the oprde chapter (or there were 2 such important points for such a fanfic). Of course I won’t spoil it, I’ll just wait to make sure whether this fanfic is almost completely copied or not.
