I would say it’s a tie between Sovanna and Tendri. Sovanna is the MC in Solar Song, Frozen Fate. She loves to have fun and is smiling most of the time. She doesn’t make others feel bad or lesser than when being around her. She’s also confident in who she wants to be which also translates into her personality.
Tendri is the younger sister of MC Pinti in Lunar Heart, Shadow Bound. Tendri is sunshine if sunshine were a blue feline
Despite living in hardship, it’s all she’s known and she rarely shows a frown even when she’s not feeling particularly smiley. She’s a flower blossom, always radiating good vibes and she makes everyone feel special to be her friend.
Hands down raven girl Wescherlie, the supporting character from Lone Gold, Daring Purple. Wescherlie is fifteen, but she’s been around the block and has had to deal with things most her age would not have to deal with. She’s also insightful which helped her learn how to navigate difficult situations. She’s grown up fast and can even give profound advice about self-love and self-acceptance.
Sovanna. She’s not a “things make me happy” girl anyway. If she has family and friends she doesn’t need anything else 
I’ll talk about Sovanna since her story was recently finished. Sovanna’s second goal is to have a family of her own. It’s to keep lionkind alive and she also wants to be a mother. She’s heard so many lovely stories about her own mother she never got to meet, so she wants that for herself, too.
Ramen and sushi?
That’s all I can think of.
I can say that Mason, a supporting character from Paws Chase Murder Case would love Asian cuisine. He loves drinking, so he would definitely enjoy sake with sushi and have the time of his life. His friend, MC Scotch would have to be convinced XD
But who would hate it? Hmm… Even I’m not big on sushi XD
Maybe Taro, the bird guy from Solar Song, Frozen Fate. He turns his nose up to most things raw. He might eat the ramen, but he would not try the sushi. Despite being a wild creature himself, he doesn’t like eating raw food. He can eat it and be okay, but he prefers it cooked.
