"Okay! I just need you to focus on the coin!" She declared as she began swinging it in front of Kawakami's eyes

"Watch it swinging back and forth, see the shimmer of light hit the coin. Feel the warmth radiating from it. Let that warmth wrap around your whole body..." Futaba continued, going on a bit of a rant as she tried to drop Kawakami down into a trance. Honestly, as usual for Futaba, she got a bit distracted with her induction. She didn't even realize anything had changed until she started to hear very faint snoring.

Coming out of her little obsessive rambling, she noticed Kawakami was now slumped down in their chair, her chin to her chest, snoring gently.

"Oh wow! You really WERE tired!" Futaba exclaimed. Kawakami didn't wake. She was clearly very hypnotized - which Futaba theorized was from her lack of sleep causing her to fall deeper than expected.

"Mwehehe! You shall call me Master Hypnotist Futaba, for I have entranced my beloved teacher!" She declared to... Well, to nobody really. Just narrating as she often did. Though...

"Yes Master Hypnotist Futaba..." Kawakami sighed in her sleep

Futaba immediately looked back to her, eyes wide.

"O-oh uh... That wasn't mean to be a command... Oops." She giggled bashfully to herself, before being struck by an epiphany

"Wait... Why did she obey a weird command like that..? Is she really THAT hypnotized?" Futaba mused aloud.
