Daybit Sem Void
One of the seven Crypters—Masters working to replace human history with an alternate one from the Lostbelts. Before turning to that cause, he was one of Chaldea's 48 Master candidates and served on A-Team.
He was originally expected to summon a Berserker-class servant, but it's been confirmed he actually managed to summon a Grand servant instead—a major deal that sets him apart from the other Crypters.
