An Unjust Crossover, but with a Death Note

After transmigrating as Light Yagami, he acquired a mysterious notebook. Anyone whose face he had seen would die if he wrote their real name in it. From then on, Light understood that he had said goodbye to romantic high school comedies. In this crossover world, full of thugs, criminals, and murderers, where morality was corrupt and the law had fallen apart... As an ambitious villain, Light immediately decided to become the god of the new world. When faced with powerful enemies that even Public Safety's Anti-Devil Special Division 4 and the law could do nothing about, Light silently raised his pen. Bullies tormenting a deaf classmate? Kill! The serial killer in Morioh? Kill! The serial cannibal in Kannonzaka City? Kill! ...Yukinoshita: "You can't create anything, obtain anything, or give anything. The Death Note is nothing but a fake." Makima: "Capture Kira, obtain the notebook, and create a world where everyone is equal beneath me and Mr. Light for the rest of their lives." Ryougi Shiki: "Anything that's alive, even a god, I'll kill for you... You're Kira, aren't you, Light Yagami?" (Her eyes open, and she draws her sword.)
