Inoue Kikuko is referred as "Onee-chan" ("big sister" in Japanese) and stayed with the title on her official site and a few albums because of her role as Tendou Kasumi in Ranma 1/2; this is confirmed in her online profile. She believes that in her past life she was a fish and therefore uses fish as her trademark.

She always calls herself "17 years old" (井上喜久子１７歳です). Fans would refute her jokingly with "Oi! Oi!" (roughly equivalent to "yeah right"). To further promote her ideal, she founded a "cult" of "17-year-olds" (Juu-nana-sai Kyou, １７歳教). Current cult members include Yukari Tamura, Sakura Nogawa, Rina Satou, and Yui Horie.
