Beyond is a young man with black hair and shadows under his eyes. He wears long-sleeved white shirt and faded jeans. He is thin and fairly tall but always walks hunched over. Beyond was born with the eyes of a Shinigami, which allowed him to see and know when exactly people around him would die, as well as knowing their full names. Beyond and A were the first two children in line to succeed L. Later, after A’s death, B left Wammy's House at some unknown point.
