The idol voice actor project "Tiara☆Stars" has begun! The opening of this exciting initiative, filled with anime, games, and radio, kicks off with a competitive live performance between selected units. Among the participating senior voice actors, the leader is none other than—Yuuhi and Yasumi!? "Why are you the leader?" Mint Futaba, an elementary school voice actor with eight years of experience, is not pleased with the unit "Miraku" led by Yasumi. "Isn't it strange to think about winning and losing?" The atmosphere worsens as she clashes with the older newcomer voice actor, Kazariri. The gap between Yuuhi's unit "Altair" and theirs only widens. But— "Let's compete, Yasutane Yasumi." Even when not by her side, her fighting spirit for Yuuhi gives her strength! Can Yasumi, who is surrounded by problem children, grow and lead her team to success? This is the sixth installment of the intense youth voice actor story, featuring new hidden and revealed voice actors!
