Deus Ex Machina

デウス・エクス・マキナ

The deity of time and space, Yukiteru's alleged imaginary friend, and the architect of the game. He is seeking a successor, which is why he distributed future diaries to twelve candidates and forced them into a battle for survival. He appears to favor Yukiteru above all other candidates as his potential heir, owing to the miracles Yukiteru manages to achieve, while overlooking the fact that Yuno is assisting him.
Deus Ex Machina translates to 'God from the machine' in Latin.
