The God of Death in the Kexue World

After the ending at the warehouse, Light Yagami woke up as Tsukiji Shiraishi and became the son of a high-ranking member of the Metropolitan Police Department. Cases occur frequently in this world, famous detectives are active within the cordon, and black organizations lurk in the shadows of the city. The black note in his hand is still effective, but he is no longer eager to stand in the spotlight. After learning the lessons of his previous failures, he chose to dive under the water, observe detectives, get close to the darkness, and use the rules to re-plan his own order in the world of science.
