Wait for "detention."

I decided against making any risky moves for now and simply studied and did homework while waiting for my detention with Midnight. In fact, I had an idea that would make putting triggers in girls easier, just had to put another one on Midnight first.

So at 5:30, I headed for her classroom, and entered. "Ah, Mr. Doe, have a seat, and just study for the next half hour," Midnight told me.

"I'll get right on that Sensei, but first, could you come over here and meet my eyes?" I asked with a grin.

She shrugged, my trigger rendering her unable to refuse, and walked over, before I met her gaze, and was once again greeted with her blank stare. Perfect.

"Alright Midnight, when I say "Helpful teacher," you will not only not care from that point on who I use my Quirk on, including yourself, but you will actively help me use it. When I ask you to, you will arrange to have a student come and discuss classwork with you in private, and will make sure I am present as well, so I can use my Quirk on them. You will do whatever is needed to help me with that, and ensure I am not interupted while placing my trigger in them."

Satisfied, I let her come to, triggered her, and stuck around until 6 for my fake detention before heading home for the day.
