Yes, so Ren hypnotizes her

"Ren, I know you did something," Makoto said.

"What makes you say that?" Ren asked innocently.

"Okay," Makoto stopped Ann. "Then why don't I look this disease up?"

She pulled out her phone, and...

"Phantom Thief of Minds," Ren said, watching as Makoto, Ann, and Futaba fell into trance.

"Futaba, Ann, you played your parts beautifully."

"Thank you, sir."

"Let's see here...first and foremost Makoto, you need an animal trigger. So make the sound of the first animal you think of."

"MOOOOOO!" Makoto practically yelled.

"Cow, huh?" Ren snickered at the image of his girlfriend acting like a cow. "Okay, when I say 'Mako-Moo', you will become a cow."

He then thought to Makoto's freeze trigger and Ann's Simon says trigger. Futaba needed a trigger like that, too.

He racked his brain, wondering if he should input a trigger that was the opposite of Futaba's personality, like a slutty cheerleader or a confident superheroine, or maybe stick with her gamer girl aesthetic and make her a robot...or just something that allowed him to play with her body at will, like the aforementioned triggers already installed in Ann and Makoto.
