To begin with english is not my main language so sorry in advance for the following misspellings thanks for reading
This idea at the beginning will be generic isekai but I will try to do my best so that it does not break the plot.
The concept is that each death of subaru that subaru copies the most special ability of his killer
This idea if not used well will break the plot and to avoid that I will put certain rules to prevent them from breaking the plot
1:Subaru will not completely copy the ability of his assassin Subaru would copy from 100% to 5%
2:To add a certain internal conflict for each death suffered by a human or semi-humanSubaru will start to look like his murderer his changes are minimal but if subaru dies several times for one person the change will increase an example if subaru dies for Felix he will not have his cat ears but if subaru dies 50 times for felix he will start to get slight bumps on his head head if he dies another 50 times he will have a kind of horns and if he dies 50 more for Felix he will have his cat ears (Do not use the scale I used it was only for exemplification you can alter the number of deaths to better suit your story but don't make subaru's first kill by Felix already have his cat ears )The idea that the cost of power for subaru is losing parts of him until a certain point is unrecognizable, a collage of the mistakes he has made, a collage of what he hates most, a collage of its consequences.
A walking collage
If you've made it this far, I appreciate you reading this.
You can use and modify this idea to your liking
without more I say goodbye
