Unjust Anime, but with Death Note

After traveling through time and space as Light Yagami, he obtained a magical notebook. As long as he wrote the real name of someone he had seen before, that person would die. From then on, Light Yagami knew that he had said goodbye to youth romantic comedies.
In this world full of villains, criminals, murderers, moral corruption, and lawlessness... As an ambitious villain, Light Yagami immediately decided to become the god of the new world.
Faced with a powerful enemy that even the Public Security Anti-Demon Section 4 and the law were helpless to deal with, Light Yagami silently raised his pen.

Makima: "Capture Kira, obtain the notebook, and create a world where I am equal to the Moon Lord for life."
Ryougi Shiki: "As long as it's alive, I will kill it for you to see, even if it's a god... You must be Kira, Light Yagami——" (opens his eyes and draws his sword)
