After watching the 2nd anniversary stream and Tsubaki eating that pizza, I can see why Haruna blew it up.

Oh hey, I know someone who used to work for Little Caesars' R&D, and he spent most of his time there designing a pizza-making robot.
For the record, he never believed the project would ever be completed. He was just like "Yeah, they're paying me pretty well to work on this thing, so I don't really care that none of this work will ever amount to anything."
