While you're at it, why not remove the pervert harem-seeker, the black hole, the beta and the edge lord-too?
"My Instant Death Ability is So Overpowered, No One in This Other World Stands a Chance Against Me!" Everything that you wished for I know the title sounds strange and boring, but it is actually a very creative and amazing novel imo. Also it is very gory. Nothing for the faint hearted reader.
I don't really really read many Japanese light novels but I read a few, so maybe you can try The Man Picked Up By the Gods (Reboot) Also, there is some recommendations from Hobby Lark website which I have read the manga: https://hobbylark.com/comic-books/Light-Novels-with-PowerfulOver-Powered-Main-Character-II-OP-MC
