Koro Sensei is going to fly to China to watch a movie being unleashed there fir the first time tonight. The movie is called Sonic Ninja, a manga comic now being turned into a movie series.

Karma, thought of the bright idea, that since you’re small and tiny, to hide you in his backpack. Also he’s your older brother. He forgot you were with him and when Koro Sensei agreed to fly both Karma and Nagisa at Mach 20 to see the movie, he took you with them.

Somehow during the flight, Koro Sensei started explaining what dilatancy is. Well, while explaining it, you got the backpack open which Karma is still wearing and almost started cussing him out for leaving you in there for so long when you realized, you’re not in Tokyo anymore.
