Sumiko Kiyooka Rar -

Wait, could "Sumiko Kiyooka" be a typo? Let me consider similar names. There's a character named "Kiyomi Kiyooka" in the game "The King of Fighters" in the "Rar" series? Or maybe a mod for "Rar" (which isn't a known game). Alternatively, maybe it's a reference to a character's name that's been misspelled.
