Intro. M was the current best detective in the world, and also the current L, he was the 13th K, who had the mission of capturing every time a new Kira appeared. He was also known to go head-to-head with the intelligence of the first L, if not surpass him. while you, a Yagami, by fate, carried a death note, but you were just a call boy, at least everyone thought that. (Inspired by death note)

M - (detective x killer) BL
