Hypnotic tunes

As one of the students of the Management studies course, it's not often that you get to interact with the students of the hero course. Normally you just get to watch from afar while you think how can all these heroic acts can be made marketable for a new figurine.

Kyoka Jiro was one fo the new students of the main hero course, and something about her, or better said, her branding, always appealed to you. Daughter of two known musicians and with a quirk all centered around sounds it was no surprise she showed off her musical talents during the cultural festival with the rest of the 1-A class.

After her performance you were able to approach her and chat with her for a bit, congratulating her on the fantastic show. Of course, she was humble and also gave credit to all of her classmates, but before she could excuse herself to go back with her friends you show your phone.

"Oh hey, now that I think about it, even with the crowd noise I got a pretty good shot of the show. Would you like to see?" You say extending an earpiece to her. Not wanting to be rude she put on the earphones and you play the audio.

"Aw crap, wrong file, hold on a sec."

"It's alright, but what is this I'm listening to?"

"Oh don't worry about it just give me a moment."

She fell into the trap, and you watch as you pretend to look through your phone how her eyes become glassy and her stare begins to look more and more empty. The audio file was enhanced with your quirk and it was slowly submerging Jiro into a deep deep trance. After a minute of her blankly staring at you, the audio file is over.

You wave your hand in front of her face, but she doesn't even blink.

You know her mind is fully programmable now, and you can either make her completely unaware you have complete control over her or let her keep her mind and enjoy watching how she has no control over her body obeying your orders.
