As you sat alone on a bench at night, enjoying a smoke, a group of non-sentient robots came towards you. It seemed like a programming error at first, but then one of the robots lifted you up and spoke through a speaker:

"Don't worry, Sensei. If you don't resist, there won't be any need for these robots to use force. See you in my room."

Realization struck you that Himari had hacked the robots. They began carrying you towards Millennium Academy or, more precisely, Himari's room.
