Voice Over!: Seiyuu Academy(2009)

Seiyuu Ka!

To make matters worse, Sakura’s grouchy son, Senri, is in Hime’s class, and he seems determined to stomp on her dreams. He even has the nerve to call Lovely ♥ Blazers stupid! But Hime won’t be deterred by naysayers, her new nickname (“Gorilla Princess”), or even getting demoted to the Stragglers group. She’s ready to shine, and nothing is going to stand in her way!
