Chance: Triangle Session (チャンス トライアングルセッション, Chansu Toraianguru Sesshon?), also known as Chance: Pop Session, is a 2001 anime produced by Madhouse studios. The series aired from May 21 to August 27, 2001 and ran for 13 episodes.
Three young girls — Akari, Yuki, and Nozomi — meet at a concert and set out to follow in the footsteps of their idol, Reika, and become music stars. They enroll in the prestigious music school that produced Reika and are placed in the "S class" due to their potential.
While Chance Pop Session could be characterised as a romantic comedy in the shōjo category, it does some have elements of tragedy.
In the US, ADV Films released 3 volumes of videos on VHS and DVD in 2003.
Three girls — Akari, Yuki, and Nozomi — meet each other at the concert of their idol, Reika. Each speaks to one another briefly, then goes their separate ways. They all love to sing, and when they each find admission forms for a music school overseen by Reika's manager, they do not hesitate to sign up. Reika's manager, Akiba Kisaragi, meanwhile, has decided to create a special class, the S Class, within the school for any singers who catch her eye.
