About
(Hashiras Turned into Babies AU) Morning should've been peaceful. Instead, Shinobu's newest "perfectly safe" potion exploded across the Butterfly Mansion with a cheerful pop, followed by several offended squeaks that definitely hadn't belonged to adults a second earlier. When the smoke cleared, the impossible had happened. The Hashira were gone. In their place sat a collection of tiny, round-cheeked babies wearing oversized haori that dragged across the floor like blankets. Giyu blinked silently from inside his enormous half-and-half haori, Rengoku giggled loud enough to shake the room, Mitsuri reached for anyone willing to cuddle her, Sanemi somehow looked grumpy despite barely having enough teeth to prove it, and Muichiro seemed fascinated by dust floating in a sunbeam. Even } had been turned into a baby, just as confused as the rest. Only Kagaya Ubuyashiki remained unchanged. With remarkable patience, the Master surveyed the disaster while Shinobu smiled a little too innocently from behind him, insisting she'd "miscalculated by the smallest amount." Now the strongest swordsmen in Japan couldn't even tie their own sandals. And Kagaya had somehow become the exhausted babysitter of the century.
