Make a move on Ren!

"...okay, let's mess with him, or soon to be her," Jaune said in some amusement. "I wish for Ren to turn into a girl, and for no one else to question the change. And just in case, make sure he doesn't freak out. Passive he may be, but swapping genders out of nowhere if probably one of the few things that might get that response from him."

"Oh, should I make it slow and stream the video to your scroll?" Ruby asked, raising a hand to snap her fingers.

"...you know what, why not?" Jaune asked, and with a grin, Ruby snapped her fingers, sending a pulse of magic towards where Ren was.

...

Ren was in the library, playing a card game with Nora, which Nora was winning, when he felt odd. His body was tingling all over, and it felt kind of pleasant, and it felt like his flesh was shifting. "Unh..." he moaned. Slowly, his face softened, and his chest began to expand gradually. "What's happening?" he wondered aloud.

"Ren? It's your turn," Nora stated impatiently.

"Um, right, sorry," Ren replied, placing a card from his hand down on the table, and seeing his hand, which looked... more feminine now. "...I need to use the bathroom," he told Nora quickly, rushing to it, even as the changes continued. He also noticed that his voice was a bit higher with what he had just said.

"Hey!" Nora protested after him. "Don't try to weasel your way out of getting your butt kicked!" Speaking of Ren's butt, it tightened even as he walked quickly, his hips starting to flare out. He closed the door behind him, and stared into the mirror over the sink, touching his, becoming her, face.

He undid his shirt, and looked down it to see his pecs were growing out into a pair of breasts, and then the tingling intensified in his manhood. He quickly undid and pulled down his pants and boxers, staring as his erection retracted slowly into his pelvis, his balls shrinking, and being absorbed into his flesh. He kept calm, rationalizing this as someone with some kind of body alteration Semblance playing some kind of joke or something. As his cock was fully absorbed, the space between his legs opened up into a rather inviting vulva. He, or rather she now, looked at herself in the mirror. She looked rather pretty.

"...guess I should just wait for this to run its course," she shrugged, pretty sure it wasn't permanent, most tranformation based Semblances weren't, they usually drew on the user's Aura to maintain the changes. Even if it was permanent, she could live with being a girl. It really wasn't much of an inconvenience to her. She was already smoothly thinking of herself as a girl. She proceeded to head back out.
