Gogo 4-ji. Toumei, Tokidoki Seiyuu

I, Rana Yamada, am a plain, unremarkable, "invisible" high school girl.

Even when I try to create something, nothing ever comes of it, and I’ve resigned myself to always being a background character. Then, one spring day during my senior year, Shion Kagesa, a super-popular voice actress whose voice sounds like mine, suddenly finds me! She tells me, “There’s something that only you can do…”

“Will you switch places with me?”

Me, an amateur, replacing Shion as a voice actress!? That's absolutely impossible... But I find myself wanting to try it. The thought that “my voice” is needed made my heart race. Diving into the thrilling world of anime production disguised as Saion, I discover that there are roles only someone "invisible" like me can play—!
