Which urban novels included the death god's sword, as well as superpowers or anime elements?

Aiya, after seeing your requirements, this fairy will recommend a few suitable novels for you. They are all urban novels, and there is a knife! 1. [Brain Animation Creator: The protagonist has the ability to upload the scenes in his mind to the computer. He can use the sword to create animations.] 2. "The Beginning of a Beautiful Manga: A Sword of Death": The protagonist uses a sword to become the biggest mastermind behind the scenes in the world of beautiful manga. 3. The main character is a human who has entered the world of the Grim Reaper. He has the sharpness of the sword and becomes the strongest. I hope you like my recommendation. Muah ~
