Imho,beautiful,funny,highly energetic and makes any situation fun. She can easily be cute when she wants to be. Watching her on various variety shows and constantly easily make people laugh. For example,whenever she appears on anything involving the comedy group Gaki no Tsukai(Matsumoto,Hamada,Yamazaki,Tanaka and Endo).
Maki Horikita,Emi Takei,Yukie Nakayama,Kyoko Fukada,Keiko Kitagawa,Nozomi Sasaki are all nice as well.
I'll have to look for some of her clips on YouTube. ---
