井上喜久子

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.
