Misato: A pair of earrings. There will also totally be a nice Christmas dinner because everyone knows that Shinji is actually the wife in this household.
Panda: Panda-shaped cookies baked and decorated by Shinji himself. (Though, where the pandas should be black, they're colored blue, pink, and yellow instead. He had leftover frosting from his Secret Santa present, okay.) He also gets a winter hat shaped to fit his ears and a Christmas card left over from the party.
Pilouette: A hairbow and pink gloves to match. Why this particular design? Because of that one time she "led" a biker gang. :') She'll also get some cookies, but hers will be shaped like snowmen and decorated with pink frosting.
Hayate: A written apology from Pen-Pen. A razor to shave his beard. Anti-aging cream. A model kit. Since Hayate was really into video games, he figures he might like a boy-ish thing like that. He gets cookies shaped like Santa snowmen, too! His are frosted blue.
Arata: A thick book about magic and lore from all kinds of different cultures. There may or may not be a naughty magazine stuffed inside the book. He gets snowmen cookies that are frosted purple.
Yurippe: A knit hat, except in green rather than blue. She gets snowmen-shaped cookies also frosted purple.
