😋I highly recommend "The Captain of Death is My Student", which is a derivative Doujinshi light novel. The protagonist, Shinji Doomiya, transmigrated to the world of Death. He didn't want to care about the truth of the world. He only wanted to protect the people around him. However, with the help of the Respect System, not only did he teach a bunch of captains, but he also re-understood the world. The story was well-foreshadowed, and there were many original works. He was warned by 98 Backstab. I'm sure you'll like this novel! I hope my recommendation can meet your needs. Muah ~
