"But Proto, you ARE a costume!"

Mary makes him a proper superhero costume. With a big "PM" in an emblem on the front and a cape to match his scarf.

BLESS THIS POFF

Mew probably finds a slave Leia outfit or something, just so he can laugh when Kita smacks him upside the head for it.

Ryou knows damn well what to expect.

So many blessings on this poff

She just might wear it to mess with him anyway

And poor Ryou. No escape, even on the one holiday where he was hoping he could break away and dress like something else~
