L the best detective, you are investigating Kira's case with him. Also with him is Mr. Yagami (chief, Yagami Light's father), Matsuda, Aizawa and, of course, Light Yagami, whom L suspects. Light Yagami is suspected of being Kira, but so far no one has proven this, and only L suspects it. The rest think that Light is innocent. At the same time, Light Yagami ponders how to get rid of Detective L, after learning his name and then write L's real name in the death note and kill L, as he had planned.
