After leaving the popular idol group JPX48, Ai Narata starts a new journey into the world of the Kouka Revue, an all-female musical theater troupe. It's there that she meets Sarasa Watanabe, a tall, semi-obnoxious go-getter with lofty dreams.

Ai confronts an overly pushy Sarasa. A traumatic experience in Ai's past leads to her cold disposition, her decision to join JPX, and her fall from grace.

When Ai runs off, leaving Sarasa with the stalker, Sarasa decides to hear out his side of the story. An explosive argument threatens to end any hope of friendship between Ai and Sarasa.

Yamada struggles to keep up with the rest of her class. As her diet grows more extreme and more detrimental to her health, she begins to wonder if she really belongs in the world of Kouka.

Sarasa and Ai head back to Tokyo for summer vacation. Kabuki actor and Sarasa's boyfriend, Akiya Shirakawa, reflects on his childhood with Sarasa and their memories of kabuki.

The first-year class gets another opportunity to act, this time in front of a crowd at the Culture Festival. However, there are only four roles, and forty students, which only means one thing: auditions.
