Haruka - Probably my favourite character of all time. She got me back into the show, and brought in contests; if it weren't for that, I probably would've never gotten back into the show. She has a great personality and was probably the best thing that happened to the show after Johto, imo. I hope she stays for a long time.
Shuu - Shuu is teh awesome. XD Seriously. I guess I can see why people dislike him, but really, he is very nice/caring at heart. He also has that inside dorkiness about him, ("Yummy!" and "Phoney bolgna!" XD) and even though he's Haruka's rival, he looks out for her. You gotta love the hair flipping, and the way he combines his style with his coordinating. It's just too cool, and I love his pokemon. <3
Satoshi - What can I say? XD He rocks. [/has nothing else to say about Satoshi just that she likes him for the reason being that he rocks]
Other Characters That Aren't My Favourites But I like - Kasumi, Masato, Kanata, Robert, Shigeru, Hiroshi, and Sakura.
