Second season of Yatogame-chan Kansatsu Nikki.

Mew and Mica are alien androids sent by their boss to defend the Earth. Unfortunately for our planet, they are the laziest superheroines you will ever meet. Now most superheroes would drop whatever they're doing, transform, and proceed to kick monsters' butts... but these two would do no such thing. Mew and Mica just can't let their duties interfere with their ice cream, arguments, or whatever activities they happen to be engaged in at the time. When they are not Hyper Dolls they seem to be just ordinary, rather cute school girls, lusted after by the boys.

The story centers around an illness-stricken, constantly bullied orphan girl named Minori. After one rainy day, she doesn't turn up at school, having been admitted into a hospital in a distant town. Two months pass, and the girl's two school friends, Takashi and Kyouko, receive a mysterious email with no sender listed. The email reveals a summer festival taking place at a nearby town...

At the performing arts division of Seisho Music Academy, the ever-evolving stage threads the lives of its students together as they tirelessly hone their craft. Yet, as the girls prepare for a new rendition of the previous year's performance, the carefree Karen Aijou begins to settle for a smaller role. However, her waning passion is reignited by the return of her childhood friend Hikari Kagura, whose sudden transfer to the academy triggers a flurry of changes in the class dynamics. Subsequently, Karen chances upon a secret battleground underneath the school, which houses a set of auditions that will crown its ultimate victor as "Top Star." As she dives headfirst into these enigmatic trials, Karen begins to learn about the tribulations that come with vying for the top. Even if fate wills them apart, Karen and Hikari must fight in hopes of fulfilling their childhood promise: to become stars together. [Written by MAL Rewrite]
