I think Yasusada would definitely be the type to believe in Santa if he was taught about him. And he would want to make the Santa Kami happy!

Kane-san would act like its beneath him to believe in such silliness but he would actually believe and apologize to Santa in private

Shokudaikiri would definitely believe and if his other Date-gumi didn't he would write notes to santa apologizing and being like "Please forgive them they are so sweet and kind, they mean well!" and make many snacks for Santa.

THE GREAT MAMMON-SAMA canonly believes in Santa and Lucifer slips gifts to him "from Santa" so he isn't sad

ALSO PLEASE TELL ME OF YOUR HEADCANNONS/CANON THOUGHTS OF YOUR CHARACTERS TOO

lmfao all of your characters believe in Santa...!!!

Listen!! You have to respect Santa Kami!!!

in Descendants, Santa is a real person XD Lonnie believes wholeheartedly

oh no thats adorable ;u;

yep!

it's different for Miharu since Christmas is the KFC holiday

mmm fried chicken...

Santa-san is like a children's character for her, at least

Grandpa wants to chat with Santa

Kara probably believed in Santa since, according to Canon, she came to Earth right around the holidays. she was young enough to be convinced to believe in him despite Kryptonian logic telling her no XD

Minato and Miharu hands clasp at the excitement of KFC

Chimken 🤤

Sonica: Jiji leave out cookies and you can!!! (just dont leave them unattended cause Yasusada will eat them)

of course, as an adult she doesn't believe in him anymore

I have a feeling as much as Mami is the mature one, she definitely believes in Santa

Belle likes the story of Pierre Noel and definitely believed in him growing up

Ichigo will be your Santa, Mitsu! (he has to be Santa anyway for all his brothers! XD)
