A cute and lovely person, Ozeki Rika is often the subject of affection from her fellow 1st Generation members and even her juniors. As the third personality/host of the group's regular radio program, "Kochi Hoshi," Ozeki improved her communication skills, which has shown in other events and shows as well. Not only is she well-spoken, but she is also capable of writing beautiful calligraphy and delicious cooking. Another characteristic of her is "Ozeki Style", a term coined from the unique running style and her movements in general.
