Death Note 5 Ohba Tsugumi (2007)

Light Yagami is an ace student with great prospects, but he is bored out of his mind. Everything changes when he finds the Death Note, a notebook dropped by the rogue Shinigami death god Ryuk. Any human whose name is written in the notebook dies, and Light vows to use its power to rid the world of evil. When criminals begin dropping dead, the authorities send the legendary detective L to track down the killer. After a week locked up with no one but Ryuk for company, Light is ready to give up the Death Note and all memories of it. Freed from his past actions, Light is convinced he is innocent, but L is ready to keep him under lock and key forever, especially since the killings stopped once Light was incarcerated. Then a new wave of Kira crimes hits Japan. Someone else has obtained a Death Note, and these new deaths are not focused on making the world a better place, but on making money. Big business can be murder, and Kira has gone corporate.
