Manga author Miho Obana makes several cameo appearances in the television series, where she is seen wearing a pink kimono and sometimes plays a saxophone. She occasionally pops up in the background, was a contestant in the quiz show episode, and was also the fiancee of Takuya Kimochi, an idol singer of the group SNYAP (a spoof of Takuya Kimura.) Also, her name is frequently referenced: as the author of various books the characters are reading, as the license plate of Rei's car, and as the name of a never-seen school friend of Sana. The only thing she says is "Obana-desu", or "Obana here" in the English dub. (Source: Wikipedia)
