A



A is only mentioned briefly once in the book Death Note: Another Note: L. A. B. B. Murder Cases (spin-off novel by Nisio Isin). He was the original successor to L and one of the first Wammy Kids (along with B, a.k.a. Beyond Birthday). He lived in Wammy's House with B. The only other known fact about him is that he couldn't handle the pressure of having to succeed L and committed suicide.
