You're Chuuya

Chuuya and Dazai were having an average soukoku interaction outside as they walked to the store. Dazai teasing Chuuya, and Chuuya being the angry little chihuahua he is.

When suddenly...

Dazai turned into a...uh...a baby.

Chuuya stared dumbfounded at the baby Dazai.

"Why the hell did his clothes and bandages shrink with him- WAIT WHY AM I QUESTIONING THAT HE JUST TURNED INTO A FCKN BABY!"

Dazai whines and wails in confusion.

What do you do?
