Syo- Some cool videos he found in the Department Store that reminded him of Syo's favorite show. (I wanted to get you something else, but I'll just wait until we get back home, okay?)
Rise - A charming silver necklace with a cute star. (I think Rise-chan would look really nice in this one!)
Choutarou - Fluffy earmuffs. (You should always protect yourself from the cold!)
Yayoi - A t-shirt with a cute pikachu print in front. (I saw this and thought of you. I think you'd look cute with it.)
Ven - A nicer-looking bag compared to the default, colored red and white. (Do you think you'd use this? I think it might suit you.)
Shizuki - A cd with some nice pop music. (I hope you'd like this!)
Rapunzel - A guide to pokemon battles. (I hope you're doing well with your quest!)

Everyone else gets hugs a small bag of candy.

To be given late (probably after New Year):

Choutarou - A really nice jacket that he can use all year round. (Make sure to wear this, all right? I bet it suits ya.)
Makoto - A CD with some nice rock songs he heard inside the Department Store. (Hey, if you're performing, lemme hear you sing something like this.)
Misaki - A nice headband with a ribbon at the side. (Maybe this'll help.)

Shuusuke - Homemade spicy curry and a 'date', also decorations for his cacti pots. (I guess it's not so bad spending holidays with family, right?)
Saeki - A nice, form-fitting shirt with an interesting design in his favorite color. (I hope you like it, I tried to make sure it was in your size.)
Shiraishi - Compass. (I promised to stop worrying, but I think I'd feel better if you had this at least.)
Tezuka - ... A nice glasses case. (Thanks for taking care of my brother.)
Kisa - Some hairclips with tulip designs + a hairband with the same design. (I hope you'd like these. I thought they might look good on you.)
Akaya - Compass. (Thought you might need this.)
Choutarou - A pair of warm gloves. (It's not much, but I think at least for winter, it'll look pretty cool.)
Rise - A bag of cookies. (Sorry for the hard time my brother gives you.)
Wataru - A nice fantasy pokemon character figurine. (I wasn't sure what you'd like, but I hope this is good.)
Yagyuu - Wristwatch. (I hope the holidays are treating you well.)
Other Father - A nice blue scarf. (I hope things are going well in your home, sir.)

Everyone he knows in Goldenrod + the ones on the list also gets a small bag of chocolates.
