I like the way how Tomoyo thinks and acts to whatever Sunohara throws at her. She just acts calm and accepts the challenge made by Sunohara, even though he knows already he is no match for her. I mean if I was in her position, I would really be irritated and probably just put that guy in the hospital already if that person hasn't learned it's lesson yet.
But out of all the Clannad girls so far in the show, I like Tomoyo the best next to Kyou. Both characters have certainly made their presence really known in the show. I wonder if she has a story behind her that makes her what she is now. I mean there must be some reason why she can fight like that unless she takes Karate classes for fun. Although I've heard that Tomoyo became a very popular character that Key decided to make a separate game just for Tomoyo. I wonder if Kyoto animations will decide to do an adaptation to that one as well.
