He gets two volunteers actually!

"ME!" Tooru and Setsuna shouted at once as they stepped into Itsuka's place, before pausing and looking at each other with sheepish and mischievous grins respectively.

"...okay, so who goes?" Ochaco asked with a giggle. "And why do you both want to be in the dream?"

"I just like the idea of sleeping with a famous Hero a bit," Setsuna admitted without an ounce of shame in her demeanor.

"Of course that's why," Itsuka playfully rolled her eyes, and Setsuna stuck out her tongue.

"I want to be ogled by him in a nurse outfit," Tooru giggled into her fist, flushing slightly.

"That makes sense too," Izuku chuckled. "Though we're going to have to make his memories of your appearances fuzzy, just in case he meets you while awake," he added, making Tooru pout but nod. "...can anyone think of any reason we can't have two nurses "treat" Ingenium?" he then asked the girls.

"I got nothing, ribbit," Tsuyu shrugged. No one else has any reasons in mind either.

"So, we doing this now, or we waiting until we sleep normally?" Setsuna asked. "I don't want to miss Itsuka's initiation after all..."

"Izuku and I can always spar a bit while you guys are under, then do the initiation," Itsuka suggested.

Tooru grinned. "Master getting his ass kicked? I don't want to miss that either!"

"True, but initiation happens only once per girl, right?" Setsuna reasoned. "... Izu-kun will keep getting his ass kicked by Itsuka in Quirkless combat for a while yet."

"Hey!" Izuku pouted as everyone laughed at him as he blushed. "Alright, let's do this now. The longer Ingenium is in his current condition, the longer he and his family will live with the assumption that he's crippled for life." With that, he made the wish, after making sure Setsuna and Tooru were seated of course, so they wouldn't collapse, and they slumped, **** after Momo snapped her fingers.
