Ozeki Rika quickly became famous for her running style, nicknamed "Ozeki Style" by the MC of Keyakitte, Kakenai. But she is also a skilled calligrapher and has played piano from 7 to 13 years of age.
While she is better known for her "almost scaringly weird Ozeki-style" character, she actually wishes she could be a more normal idol. Much like Ishimori Nijika, she admires Kobayashi Yui for pulling off the composed&cute look that is impossible to her, and she has been seen consciously trying not to overdo her weird running signature style.
Her audition song was Sakura no Hanabiratachi (AKB48) and her favorite Nogizaka46 member is Ikuta Erika.
