When Dorothy first entered the classroom of the Automated Mechanical Civil Engineering major, she was quite intimidated by the numerous "Gundams" and "Transformers" that filled the lobby.
At the time, she thought they were some sort of formidable war machines or something. After a closer look, she realized that these things were actually engineering machinery made by Spider Teacher. And the teacher had mentioned that these were just trial products she made casually and would eventually be sold off to the otherworldly races in bulk.
Back then, the homebody witch wondered which unlucky sod would end up buying these pieces of construction equipment, but now...
Well, the clown turned out to be myself.
Damn, after going full circle, these things have ended up back in my hands again.
