"Ochaco Uraraka will enter a trance whenever Jett Walker says to her the phrase, "Gravity of the Mind." While in this state, she will mindlessly obey any command given to her by Jett, and when awake, will follow any subliminal commands he implanted in her mind," Jett wrote, going a hypnotist sort of route this time. "She will wake when Jett tells her, "Gravity Released.""

"Um, hello? Please don't ignore me," Ochaco whined a bit, watching him write from where she was curled up, doing her best to cover her nudity. "Can I have some clothes please?"

"Ah, sorry, just had an important thought to write down," he remarked, closing the Sex Note. "Now then... Gravity of the Mind."

Ochaco's expression immediately went blank, and she slumped somewhat. "Unh..." she moaned as her mind essentially shut down on her.

"Stand up," Jett ordered. Ochaco mechanically complied, rising to her feet, her arm over her boobs, and her other hand covering her pussy. "Move your arms, hold them at your sides," he continued, and her arms went limp as she also complied with that.

"Oh? What did you do to her Master?" Esther asked curiously.

"Oh, just drawing some inspiration from hypnotists this time," he remarked, gazing at Ochaco's nude form.
