Deteoh – A Glitched World’s Isekai Story

When you die you're supposed to just go to either an afterlife worthy of your exploits or get reincarnated and start all over.
Or you can be like me and volunteer to play hero to save a world!
I even managed to negotiate immortality as a reward, well I have to become a vampire for that but its not half bad.

Glitched skill system?
God devouring artefacts?
Death counts in scientific notation?
What do you mean I just killed the heroine?
What have I gotten myself into.
I get the feeling I'm playing on impossible difficulty.
Also why does everyone make such a deal about how I died?
Just because I don't understand the scientific principal at fault doesn't make it important, right?
