Ogin Uonome (ふかづめ 竜子 Fukazume Ryūko) (17 years old) is a member of the Saitama Crimson Scorpions who always wears a mask with an "X" on it, thus earning her nickname "Fish-eyed Ogin" (the X resembles the eye of a dead fish). She is taciturn. She is also a good friend of Nanako Oohara. Despite her somewhat fearsome demeanor, she possesses a kind side, shown in an episode where she helps out her sick mother. Her face was revealed when Himawari playfully took off her mask in episode 226-3.
