This is one of my favorite shows of the current season. Mainly for the outstanding drawing and animation, but also because the story moves at a nice pace and the characters are vivid.
The cast is a mixture of young seiyuus just now becoming stars, and idols doing their first seiyuu work. This show is the product of a real idol project that started in 2010 and has produced a number of music videos separate from the anime.

The star is Nitta Emi, who debuted as Kotori in last year's TP Sakura OVA. This season, she is starring both in this show, as Honoka, and in DC Da Capo III, as Ricca.
With her is Nanjou Yoshino (the student council president), whose role as Akino in Robotics;Notes proved that she has become a real seiyuu, as well as the singer she is with fripSide. The other two known names in the main cast are Uchida Aya (Kotori; Himawari in Vividred Operation) and Minori Suzuko (Umi; Sherlock in Milky Holmes).
But the unknowns are even more interesting. Iida Riho (Rin) was a teen photo-idol, with numerous DVDs and photo books to her name. She has also acted in TV dramas and films.
Kubo Yurika (Hanayo) was a teen model, then after 18 put out a series of fairly sexy (but not quite nude) DVDs. She actually does have a bit of seiyuu experience, with small roles in Sakurasou, Sukitte ii na yo and a couple of other shows.
Pile (Maki) is a half-Korean singer who had a single of her own out before she joined the Love Live project in 2010.
The other three members of the main cast have come up in a more normal way, as seiyuus. Kusuda Aina (Nozomi) had bit parts in Penguin Drum and Gon. Tokui Sora (Nico) was Nero in Milky Holmes.
