...You are the school's baby! Love Live! School Idol Size Stories - Definitive Edition! chapter 6 by Ninten

Edited from EmiyaShirou's original chapter:


Your eyes widen before you look over at where Eli is pointing. Indeed, there's a fleece onesie with clouds and unicorns on it, mittens and footsies, a lace bonnet, and a diaper that would make hard to walk beyond a waddle.

"A-And I have to wear this while I'm at school?"

Eli nods. "We've already contacted your mother about it and she sounded quite pleased about this state of affairs." You blanched; your mother had always smothered you and getting to treat you like a baby would be heaven to her. "We've also made it so that the law will treat you like an infant as well. Hopefully, we can get it extended for all boys as well, but you'll be the test case." You wondered how far the reach of an all-girls school could go but decided now wasn't the right time to ask.

"I-I assume I'm not going to have any privacy to change, am I?"

"What privacy does a baby like you need? You better get used to have your diaper checked regularly and women cooing over your 'wee-wee.'" Already being infantilized by Eli, you saw little choice but to take off your clothes. You were about to put on the diaper (or at least try) before Eli slapped your hand away. "Um, what are you doing?"

"Putting on the baby clothes...?" you questioned, slightly annoyed. Eli didn't appreciate your attitude one bit. She pulled out a device from her skirt pocket.

"You think girls would want to take care of a boy their age pretending to be a baby? Uh, no. You're going to become an ACTUAL baby, literally. With this nifty device here." Eli twirled the ray gun like machine in her hand before giving you a playful smirk. She stuck out her tongue in a mocking way before pointing it at you and zapping!!

"Hope you enjoyed your last moments of having any free will, or the capacity to form words!"

You felt your body shrink and squish down into the form of an infant. Your sense of sight, sound, touch, taste, and smell all regressed. You retained your memories but they became hazy. You could form thoughts just like before, but they felt conflicted by other more basic instincts. Your mouth couldn't form words properly, it's like there was a blockage between your brain and mouth.

"Aww... look at that. Our school's first little baby boy~" the blonde goddess Eli cooed down at you. This was the nicest she's ever treated you up to this point. "Little boys aren't allowed to do anything with their diapers besides pee and poop in them. Let me lay down." Eli gently flips you onto your stomach and begins powdering your behind, finishing off by giving your butt a gentle slap and taping your diaper snugly to you. "We'll have to start giving the girls at this school mandatory babysitting classes. Hmm. You just helped us create a whole new curriculum~"

You also got to see a somewhat kinder smile from Eli after she dressed you in the rest of your baby clothes, even though she was still proud of your humiliation. Your weaker body with less motor skills couldn't possibly resist the teenage blonde.

"There we go, that's a good boy. Now, there were a lot of girls who wanted to be your mommy, including myself I must admit. So each day, you'll have a mommy randomly chosen for you. From leaving her house, going to school with her, and going back home with her, you'll stay by her side at all times. She can punish and reward you in any way she pleases. All of your mommies have different standards, but you must still go by what they say even if it contradicts something you heard previously. Do you understand me?"

You attempted to nod, but your body didn't register your brain's motor input. You cursed this baby body you were trapped in...

The door opened behind you. "And here's your mommy for the day. Greet her properly." You take a breath and turn your head. You recognize this girl, it's...
