You led her into the private rooms

“So what first Ren, new uniform? Costume? Skirts? What do you think?” Mina asked as you were led through the mall.

“First we have to get a good look at you. In private” you say, grabbing her by the wrist and leading her into one of the dressing rooms.

“Perfect” you whisper.

“This seems a little cozy doesn’t it” she joked perfectly unaware about her situation. You smiled now was the time.

“Fall asleep” you order and in an instant she fell asleep in your arms. Smiling you lay the poor girl on the ground and placed a hand onto her cheek. You had acquired two separate quirks that you knew would blend together nicely. One that allowed control of the acidity in one’s sweat, you predicted that combined with her quirks she could control that in her acid. The other would allow her to transform it like Midnight’s into a aphrodisiac, that too would blend with her acid.

But as you gazed upon the sleeping acid queen and read her mind you realised that she would be wasted as the femme fatale you had initially prepared her for. She oozed enthusiasm, charisma and boundless energy, she would do better on the larger scale.

So instead you placed one more quirk in her, one called charismatic voice, which did as it sounded. Making her voice naturally alluring and granting further legitimacy to her claims.

Now though it was time to rewrite her.

“Mina” you whisper with a glint in your eye. You so enjoyed this part “listen to me. When you awaken you will become an online celebrity. Making videos, blogs the best works. You’ll seek to blend this in with your hero work as well”

She nodded, already calculating her new career in her mind. You smiled at her, still kind and pure, but now to corrupt her.

“You’ll be completely shameless however, depending as much as possible on sex appeal and the like. You enjoy it, you’re a total exhibitionist and you’ll even use your acid to ‘accidentally left melt your clothes. You love and embrace the spotlight” you explain to her feeding into her thoughts “but in truth you’ll have a secret agenda. You’ll be working for me and my sisters, working to make Izuku’s fantasies come true. To that end you’ll rally your supporters towards any message we desire and you’ll always seek to make Izuku look good. You my dear will champion my cause”

You smile as she fell into this role perfectly then told her to awaken. You still had a shopping trip to fulfill.

A/N: on further examination the femme fatale idea didn’t work with Mina’s personality, so I've decided to save that idea for a different character down the line. Sorry if you were looking forward to it, instead I decided to use Lawless and Mapron01's suggestion of having her be a sort of online celebrity who exists as to raise support for Ren's plans
