Struck by Lightning from the Start, and Still Unconvinced!

I’m a part-time writer. I worked myself to death, then got struck by lightning and gained the ability to unleash my animalistic nature. As humans and beasts clash, I keep experiencing death. Each time I die, I gain a few more memories about myself. In the end, I begin to suspect that the only thing that has always stayed by my side is my 135-kilogram body.
