* AllStarCast: And ''how''. Even rival schools are given voice actors of note.
* AscendedFanon: Yoshiko Kainou and Hayari Mizuhara being a pair. Started as a bit of a fan pairing after their first appearances in the main series, their relationship became canonical in both the main manga and ''Shinohayu''.
* TheDanza: Momoko "Momo" Touyoko is voiced by Creator/MomokoSaito.
** Yuuki: Taco-tan, Tacololi or simply Tacos. Other characters even call her Tacos too.
** Chikako: Gardevoir.
** Hitomi[[note]]Shindouji's Lieutenant[[/note]]: Sheep. Because of her hairstyle.
** Himeko: "KISS fan" due to makeup under her eyes.
** The Kei Arakawa Corps: Kei and her four friends from different schools who are either competing in the individuals or not in the tournament at all.
* ScheduleSlip: Ritz isn't exactly the most consistent mangaka around. The series at one point jumped from being bi-monthly to getting a (''very'' short chapter) a month to stopping altogether for close to a year, then going back to monthly and bi-monthly. As of 2014, due to health complications, Ritz is back to releasing the manga monthly, with substantial breaks in between. She did publish bi-monthly chapters near the end of Nodoka's match in the semifinals, but quite a few of them were unfinished.
