Idoly Pride

Mana Nagase gets classmate Kohei Makino involved and starts her idol career in high school. She makes it to the final round of the Next Venus Grand Prix, but dies in a tragic car accident.

Mana's younger sister Kotono and a mysterious girl with Mana's voice, Sakura Kawasaki, passes the audition to sign with Hoshimi Productions. They move into the company dorms to start their path to become idols.

Kotono feels uncomfortable working as a group. When LizNoir shows up at Hoshimi Productions and gives a lesson, it helps everyone come together as a group.

Kohei scouts Mei to join Hoshino Productions and finds out that she is able to see Mana. Kotono feels resistant to her addition at first, but begins to understand why it was necessary.

Kohei splits up the group, designating Sakura and Kotono as leaders and announces the addition of two new members, Haruko and Rei. Sakura's group struggles with Rei's strict dance practice.

Hoshimi Productions' Sunny Peace and Moon Tempest have their debut concert at Hoshimi Festival. Kohei and Mana look back on the day of Mana's debut concert.
