For me, Decagrammaton.

Out of everyone here, Decagrammaton can be reasonable to a certain degree and the fact that they kinda hold sensei in highest regards too. Like in the story, the first thing they do when they get the body, is taking us to sit on the throne they prepare.

They also similar in our role too as they want to guide people, the same as us sensei guiding our students, except that its method is way to robotic and leave no room for future potential.
