Names first, then granted!

"We ready, Master?" Momo asked, raising her hand to snap her fingers. "I have all the details of the wish memorized if you are..."

Izuku took a moment to wrack his brain, before a thought occured to him. "Oh wait, we need to install triggers for changing personalities, right? And on a related note, we should also give Nomu a new name!"

"...that's right!" Ochaco agreed, enthusiastic about that idea. "We should totally rename her! On that note, we could probably name each distinct personality of hers! The names themselves can be the triggers!"

"We should definitely make it so that only Master, and maybe us too, can trigger the personalities, especially if any of the names are common..." Momo nodded in full agreement, idly pinching and tugging one of Nomu's nipples with her free hand, the other still poised to snap.

Izuku nodded. "Good thinking... for the base personality... let's go with Yumi."

"Yumi? Like the bow type?" Ochaco asked curiously.

"Yes, but it has two meanings beside that," Izuku nodded. "One meaning is strength and resilience, and the second is "new beginnings." It suits her perfectly."

"Indeed it does, Master," Momo grinned. "With her strength and durability, she's got the first one down, and this is a new chapter in her existence. Yumi it is~!"

"For the Bimbo one... let's go with Yuya, that one tends to mean "carefree." For the Schoolgirl, I think... Fumiko, which means "intellectual,"" Izuku continued to consider. "The Nurse one... what's a good name that means "caring?""

"Hikari perhaps? "Caregiver" is one of the meanings," Momo suggested.

"The maid one can be called Yuko," Ochaco added. "I think that means "Helpful." Though that does make three "Yu" names, we should have probably tried a naming theme," she joked.

"Both good," Izuku nodded, before adding, "That might have been fun, but there aren't "Yu" names that fit each one..." He chuckled. "Jun might be good for the ****... It means "Obedience" and "Pure.""

"That leaves the Dominatrix, and I suggest Kana, meaning "Power,"" Momo suggested.

"That's all settled then," Izuku nodded, and they went over the details a final time, each personality having her own name, said names a trigger when spoken as a one word sentence by Izuku or any of his girls, and the clothes magically changing for each one. With it all settled, Izuku made the wish, and Momo snapped her fingers, and a red bolt of magical energy entered Noumu's chest from the hand currently fondling it.

She finally reacted, gasping, and convulsing slightly, before slumping with her eyes closed as her new mind came into being. Then, slowly, Nomu, or rather, Yumi, looked up at Izuku, opening her eyes. She gazed at him, now stoic instead of mindless, and opened her mouth, before pausing, hesitating as she searched for the right word, before finally speaking, "...Master?"

(Yeah, I ended up getting to this before much was suggested for names, so I came up with my own, sorry guys. Should have asked way sooner, but kept forgetting.)
