Season 1

Under the leadership of the founder Sakiko, Ave Mujica's popularity and reputation are thriving. Dedicated to ensuring the success of their next stage performance, Sakiko pours her all into creating the perfect stage. However, discord arises among members dissatisfied with the band's direction.

Thanks to Nyamu's scheme, the members of Ave Mujica had their masks removed on stage.

Mutsumi's mental exhaustion takes its toll, and she makes a mistake during the live performance. Sachiko's quick reaction helps resolve the situation, but the impact it had on the audience will pose a problem for the future of Ave Mujica.

Ave Mujica continues to develop thanks to Mutsumi. There is no trace of the previous discord, and all its members are in harmony.

The band disbands in the middle of their national tour. The members of Ave Mujica each return to their own lives.

Mortis clings onto Soyo and attempts to enlist her help in order to wake up Mutsumi, who has fallen into a deep slumber. Just how will the MyGO!!!!! members react to seeing "Mutsumi", who has completely changed from her previous self...?

The MyGO!!!!! members have finally learnt the truth behind CRYCHIC's disbandment. Sakiko's broken words of not knowing who Mutsumi, Ave Mujica nor CRYCHIC are incite reactions from the former CRYCHIC members, to the point where they can no longer just stay still...

The ordinary girls have at last bid farewell to the place they called home. Upon witnessing CRYCHIC's performance, Umiri, consumed by a burning jealousy, takes it upon herself to revive Ave Mujica.

Umiri schemes, Mortis clings to her, Nyamu crashes due to her current situation, and Uika is filled to the brim with agony. As a result, everyone's hidden motives become entangled...

"I want to dedicate my whole life to you." Powerful words, but are they empty?

What we are about to show you is the story of a girl with a secret.

As fate surges before her like a raging storm, all that remains in her struggling hands is...

The path they have traveled, the scenery of where they are now. "The seasons have changed..."
