I wanted to go as far as possible with the reincarnated as a monster thing as possible, which is to say as human as I can go. I was thinking of maybe going with something like a slime, amorphous and lacking most senses in favour of interpreting sounds and it’s environment through touch and vibrations. I also had an idea for its mind controlling the body via commanding it to do things rather than it operating in the usual direct manner, but that was more a neat idea I figured would be interesting to work through the pros and cons of. 

As far as things go how much of that is fine. Totally happy to rework or come up with an entirely new idea.
