Hiiragi has short black hair tied with a pink-colored flower ribbon at her right side.
Tsubaki and Hiiragi practice basketball with Natsuhi everyday, although Natsuhi himself does not recognize their talents. However, their combination plays as a result of being in perfect sync with each other, make them unpredictable and draw their opponents to confusion.
This ability comes to its logical conclusion with the defensive move Twin Hell, a nigh-impenetrable double team capable of stopping even the most athletic players in the story in Maho and Rena.
- Hiiragi is named after the holly flower.
- The Takenaka twins were born on New Year's Day, January 1st.
- Hiiragi is unofficially listed as a Point Guard as she exhibits better ball-handling skills and defensive tendencies than Tsubaki.
