Uuuh the mysterious director has a relation with Sensei!

 

[Terithian]

@User1898 It has already been implied by this point that she was involved in the development of robots like Alpha, and since the Director is also called "Alpha", it's safe to assume from the necklace that she's a robot who was directly developed by Sensei.

@Terithian

I guess so! I mean, repairing an android in your home doesn't strike me as a common skill.
But given that Sensei never met Alpha before she was hit by lightning made me think that while she was involved in the development of alphas, she does not know all of them. So the director is still a very special Android
