I've always thought that the one who was singing the Clockwork Lullaby to Irregular was the Master of the Court, sort of like how a mother sings a lullaby to her child. Also, the text saying that Irregular couldn't escape the room is closer to Gumi's shade than it is to Miku's, so perhaps it's safe to assume that it was Master of the Hellish Yard speaking. And if Waiter's the mysterious Singer in Clockwork Lullaby, then how could she be present at the MA Project in EC 13, way before the Epitome of Vanity happened?
