There is a novel called Death Note- another note and so if you have read it give me your opinions on Beyond Birthday. I mean his natural shinigami eyes is weird.(how did that happen?) Wiht the eyes he was named Beyond(his)Birthday. He was very smart at diguising himself as L and knowing everything, I mean EVERYTHING about L. He is a very smart criminal like how he led Naomi and planned out that the fourth victim was himself. All in All , He is one who is equal to L(he was raised in Wammy's House after all) .
