This is the story of Beyond Birthday, a child, L's protégé, and a soon-to-be serial killer. He is raised out of his past into a new life at the Wammy's House but his hidden secrets remain, unknown to the rest of the world; a world in which he can determine the death of a person right down to the very second. He views the world through the eyes of a Shinigami. He remains at the Wammy's House up until the tragedy of his life. Until he leaves, he resides with a single-lettered alias: B.
B for Beyond Birthday. B for Backup. B for Beyond Insanity.
Before I trek into a life story of Beyond Birthday, the ages and year dates have been modified and justified. Here is an overview of what I have done. I have checked and checked and checked again. These ages and dates should come out matching with the actual dates and age of L. All I did was add three years and from there I calculated Beyond Birthday's information. Beyond Birthday's ages and dates were estimated, except for the Los Angeles BB Murder Cases (which takes place according to the manga's dates, not the anime's).
