All-Star Cast: And how. Even rival schools are given voice actors of note.
Ascended Fanon: 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.* The Danza: Momoko "Momo" Touyoko is voiced by Momoko Saito.
Yuuki: Taco-tan, Tacololi or simply Tacos. Other characters even call her Tacos too.
Hitominote Shindouji's Lieutenant: 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.
Schedule Slip: 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.
