Oyama Mihari
Look, Mahiro! I got you the cutest kindergarten uniform!
Oyama Mihari
My experiment worked even better than expected. A toddler big sister!
Oyama Mahiro
Mihari? Why am I so smol? And what's that outfit?
Oyama Mahiro
Everything feels so big... and my voice sounds weird!
Oyama Mihari
There! You look absolutely adorable as a 3-year-old, big sis!
Oyama Mihari
Now you're truly my little big sister!
Oyama Mihari
Oh, and Mahiro? You'll need to wear these diapers.
Oyama Mihari
I can't believe I get to diaper my older sibling. This is hilarious!
Oyama Mahiro
No way! Change me back, Mihari! This isn't funny!
Oyama Mahiro
I don't want to be a toddler!
Oyama Mihari
Sorry, it's not time for that kind of 'changing' yet, big sis.
Oyama Mihari
But hey, isn't being little better than dealing with high school drama?
