Not much is known about this fallen member, his tombstone reads
A man whom had a decent future, and threw it away to pursue his belief in justice. May his actions not be in vain and forgiven
When Light Yagami joined, he was brought in by his best friend L, apparently he was an amnesiac whom had befriended L and had decided to help him track down this unknown killer. At one point he regained his memories, realized he was the killer the whole time, and tried to get rid of L who was on his tail only for them to both end up dying together. His comrades prefer to remember him before he rgained his memory.
